Lapho kwakhiwa noma kuthuthukiswa uhlelo lokuvikela umlilo kulo lonke elaseYurophu, zimbalwa izinqumo ezithwala umthwalo omkhulu wokusebenza njengokukhetha ukuxhunywa kwepayipi elifanele. Amazinga amathathu avelele — iGuillemin, iStorz, neCamlock — ngalinye liletha izimiso zobunjiniyela ezihlukile, futhi impahla okwenziwa ngayo kungase kuthume ukuthi inethiwekhi yakho yomlilo isebenza kahle ngaphansi kokushisa okukhulu, ingcindezi ephezulu, nezindawo ezigqwala. Ukungahambisani phakathi kwezinga lokuxhunywa nencazelo yempahla kungaholela ekuvuzeni, ukuguga okusheshayo, noma ngisho nokwehluleka okuyinhlekelele ngesikhathi sokuphuthuma. Amaphrojekthi omlilo aseYurophu kumele futhi ahambisane nezindinganiso eziqinile ezifana ne-EN 14420, i-DIN 14330, kanye nemithetho yendawo yezinsizakalo zomlilo ebeka ukunemba kobukhulu namazinga engcindezi. Lesi sihloko sinikeza ukuqhathanisa okuphelele kwale mikhakha emithathu yokuxhunywa, kugxilwe kakhulu ekukhetheni impahla, ukuze onjiniyela, ochwepheshe bokuthenga, nabaphathi bamaphrojekthi benze izinqumo eziqinisekile, ezihambisana nomthetho. Ngaphezu kwalokho, sizogqamisa indlelaVaricpand International, umhlinzeki ohamba phambili wokuxhuma kwezimboni, uletha ikhwalithi yezinga laseYurophu, amanani ancintisanayo, nezixazululo zobunjiniyela ezenziwe ngokwezifiso emaphrojekthi okuvikela umlilo ezweni lonke.

Ama-Guillemin couplings, aziwa nangokuthi ama-symmetric noma ama-A-type couplings kwezinye izimakethe zaseYurophu, inguqulo yaseFrance eyasungulwa ekuqaleni kwekhulu lama-20 futhi selokhu aba yinto ebalulekile ezinhlelweni zokudlulisa amanzi noketshezi eFrance, eSpain, nasezingxenyeni ezithile zaseNtshonalanga Yurophu. Umklamo ubonakala ngezigamu ezimbili ezifanayo, ngasinye sinama-lug amabili ayisicaba nendandatho yokuvala enomgodi, ezihlanganiswa indandatho evulekile eqinisa zombili izigamu uma iqiniswa. Lokhu kuhlelwa okulinganayo kusho ukuthi noma yiziphi izigamu ezimbili ze-Guillemin zihlangana kahle ngaphandle kwesidingo sokuthi kube nezinhlangano zobudoda noma zobesifazane, okunciphisa kakhulu ukuphathwa kwempahla. Indlela eyinhloko yokuvala incike ku-gasket ecindezelwa ngokuqondile lapho indandatho iqiniswa, okukhiqiza ukuxhumana okuqinile, okungavuzi, okungakwazi ukumelana nokucindezela okuphakathi nendawo nokuphakeme. Izinto ezijwayelekile zokusebenzisa zihlanganisa ama-hydrant omphakathi, imigqa yokucisha umlilo yezimboni, ukudluliswa kwamanzi ezindaweni zezolimo, namapayipi esikhashana emisebenzini yokwakha neyezimayini. Ngenxa yokwakheka kwazo okuqinile nokulula kokubopha ngesandla, ama-Guillemin couplings ahlala eyikhetho elithandwayo ezinkonzweni zomlilo eFrance, ikakhulukazi eParis Fire Brigade, futhi aya ngokuya amukelwa ezinhlelweni zokucisha umlilo zaseSpain. Atholakala ngobubanzi obuhlukahlukene – ngokuvamile kusukela ku-25 mm kuya ku-150 mm – futhi angakhiwa nge-aluminium, ithusi, insimbi engagqwali, noma i-polypropylene, okunikeza onjiniyela ukuguquguquka okukhulu. Umklamo olinganayo ubuye unciphise ubungozi bamaphutha okuxhuma ngesikhathi sokusetshenziswa ngokushesha, inzuzo ebalulekile ezimweni zokusabela eziphuthumayo. Lapho kukhethwa ama-Guillemin couplings amaphrojekthi omlilo aseYurophu, ukukhethwa kwezinto kuthinta ngqo ukuphila isikhathi eside, ukumelana namanzi olwandle, nokukwazi ukumelana nokusebenza okuphindaphindiwe kokuxhuma emazingeni okushisa aphezulu. Ku-Ama-Guillemin Couplings, ungahlola izinketho ezahlukene zezinto ezenziwe ngokukhethekile ukuze zihlangabezane nezidingo zokuvikela umlilo.

Izixhumanisi ze-Storz zasungulwa ngo-1882 nguCarl August Guido Storz eJalimane futhi ngokushesha zaguqula izixhumanisi zamapayipi omlilo emhlabeni wonke ngenxa yohlelo lwazo oluhlakaniphile lokuvala nge-cam – noma ngokunembile, uhlelo lwazo lwe-quarter-turn bayonet – oluvumela ukuxhumana okuqinisekile ngokuphenduka okukodwa noma okubili kuphela. Ngokungafani ne-Guillemin, izixhumanisi ze-Storz zinomklamo olinganayo onamasongo amabili angaphakathi nezikhala ezinhlangothini zombili, futhi uma zicindezelwa ndawonye ziphendulwe, amasongo angena ezikhaleni enze ukukhiya okungokomshini okuqinile futhi okumelana nokudlidliza. Ukuvala kwekhwalithi ephezulu kutholakala nge-gasket eyisicaba noma eyindilinga ehlala ngaphakathi kwengxenye eyodwa, iqinisekisa ukungavuzi nhlobo ngisho naphansi kokushintshashintsha kwengcindezi okuvamile kumaphampu okucisha umlilo. I-Storz isiphenduke izinga elijwayelekile lezinsizakalo zomlilo eJalimane, e-Austria, eSwitzerland, eNetherlands, nakwamanye amazwe amaningi aseYurophu, futhi isetshenziswa kabanzi ezinhlelweni ze-hydraulic zezimboni nasekuniseleni. Enye yezinzuzo ezinkulu zezixhumanisi ze-Storz ukuhambisana kwazo namapayipi omlilo – kokubili amapayipi ajwayelekile e-lay-flat namapayipi okudonsa amanzi – yingakho cishe yonke imoto yomlilo yaseYurophu ithwala izixhumanisi ze-Storz ezindaweni zayo zokuphuma. Zitholakala ngobubanzi obungama-25 mm kuya ku-150 mm, nasezinhlobonhlobo ezinokugeleza okuphezulu kuze kufike ku-300 mm zokuhlinzekwa kwamanzi ngezinga elikhulu. Izinto ezijwayelekile zezixhumanisi ze-Storz yi-aluminium (imvamisa i-aluminium-silicon casting), ithusi, insimbi engagqwali, ne-polypropylene eqinisiwe, kanti i-aluminium iyona evame kakhulu ngenxa yokuba lula kwayo nokulingana kwayo okuhle kwamandla nesisindo. Okwezicishamlilo okumele zixhume futhi zikhiphe amapayipi kaningi ngaphansi kwezimo ezinengcindezi, umshini wokuxhuma osheshayo nesisindo esincane se-aluminium Storz kwehlisa kakhulu ukukhathala nesikhathi sokusebenza. Ukuze ubone uhla olugcwele lwezinketho ze-Storz ezakhelwe amazinga aseYurophu, vakashelaUkuxhuma Kwe-Storz lapho kuchazwa khona uhlobo ngalunye lwempahla ngokuningiliziwe.

Ama-Camlock couplings, aziwa kakhulu ngokuthi ama-cam-and-groove couplings, asungulwa embonini yezindiza ngeminyaka yawo-1930 futhi selok anwebeka kwizicelo eziningi zezimboni, kuhlanganise nokucisha umlilo, ukudlulisa amakhemikhali, nokwelapha amanzi. Idizayini ihlanganisa i-adapter yesifazane enezingalo zekhamera ezimbili noma ngaphezulu kanye ne-adapter yesilisa enomsele, futhi ukuxhumana kufezwa ngokucindezela umkhawulo wesilisa ungene kowesifazane bese ugoqa amalever ekhamesa, abamba umsele futhi acindezele i-gasket ukuze kwenziwe uphawu lokuvula. Lolu hlelo lunikeza ukuxhumana okusheshayo ngokwedlulele nokungadingi mathuluzi, okwenza kuthandeke kakhulu ezimweni eziphuthumayo, zesikhashana, nasezindaweni zokudlulisa uketshezi lapho isivinini sibaluleke kakhulu. Nokho, ngokungafani nama-Guillemin nama-Storz, ama-Camlock couplings awalingani – adinga ipheya elihambisanayo lesilisa nelesifazane, okusho ukuthi impahla kufanele ihlanganise zombili iziphetho futhi ubungozi bokungahambisani buphakeme kancane. Ama-Camlock couplings akhiqizwa ngosayizi abaningi kakhulu kusukela ku-12 mm kuya ku-600 mm, ngakho angakwazi ukuphatha konke kusukela emapayipini amancane okuphuza amanzi kuya ezinhlelweni ezinkulu zokudlulisa uketshezi oluningi. Ukusebenza kwawo ngokwehlukahlukana kuthuthukiswa ukutholakala kwezinto eziningi: i-aluminium (elula, engabizi kakhulu), insimbi engagqwali (engagqwali), ithusi (eliqinile futhi elingavuthisi kalula), kanye namapulasitiki obunjiniyela afana ne-nylon ne-polypropylene (amelana namakhemikhali). Emaphrojekthini omlilo aseYurophu, ama-Camlock couplings avame ukusetshenziswa ezakhiweni ezihlala njalo, emapayipini okudonsa amanzi, nanjengokuxhumana kwesikhashana ezindaweni zokuhlanganisa i-hydrant neloli, ikakhulukazi lapho kudingeka ukuhlukaniswa okusheshayo. Noma kunjalo, ukuba khona kwezingalo zekhamera eziqhamukile kungaba yinkinga ezindaweni ezincane, futhi i-gasket kufanele ihlolwe njalo ukuze kuvinjelwe ukonakala ngenxa yamazinga okushisa aphezulu noma uketshezi olunamandla. Ukuze uthole iqoqo eliphelele lezinhlobo ze-Camlock, kuhlanganise nezinhlobo ze-aluminium nensimbi engagqwali, ungahlolaUkuxhuma Kwe-Camlock ukuze kuqhathaniswe imininingwane.

Ukuqonda umehluko wobuchwepheshe phakathi kwe-Guillemin, Storz, ne-Camlock kubalulekile ukuze wenze ukukhetha okufanele kwezinto, futhi iphuzu lokuqala lokuhlukanisa likusezindleleni zazo zokuxhuma. I-Guillemin incike kumantongomane weringsi onentambo okumele uzungeziswe kaningi ukuze uvikele ukuxhumana, okuthatha imizuzwana embalwa isikhathi eside kune-Storz noma i-Camlock kodwa kunikeza ukuhlangana okuqinile kakhulu nokukwazi ukumelana nomfutho ophezulu. I-Storz isebenzisa isenzo se-bayonet sokujika ngekota, esheshayo kune-Guillemin futhi sinikeza ukukhiya okuhle ngomshini ngaphandle kokudinga amathuluzi, okwenza kube yindlela ephumelela kakhulu ekucimeni umlilo lapho isivinini sibaluleke kakhulu. I-Camlock isebenzisa amalever e-cam agoqeka phezu komsele, inikeza ukuxhumana okushesha kakhulu kukho konke okuthathu – ngokuvamile ngaphansi kwemizuzwana emibili – kodwa amalever agqamile asengozini yokulimala futhi uhlelo alunasimo elincane. Ngokomqondo wokwakhiwa, izingxenye ze-Guillemin ngokuvamile zisinda kakhulu ngoba zihlanganisa inathi elikhulu, kuyilapho izixhumanisi ze-Storz zilula futhi zihleleke kahle; i-Camlock iphakathi nendawo. Ngokwezinga lomfutho, izixhumanisi ezijwayelekile ze-Guillemin zibamba kuze kube ngu-25 bar, i-Storz ngokuvamile ifinyelela ku-16 bar (nakuba ezinye izinhlobo zifinyelela phezulu), kanti i-Camlock ifinyelela ku-10–12 bar nge-aluminium ejwayelekile, kanti izinhlobo zensimbi engagqwali eziqinile zikwazi ukumelana nemfutho ephakeme. Ezinhlelweni zokucisha umlilo, ezivame ukuba nomfutho ogxumayo nokushaywa kwamanzi, amandla omfutho aphezulu e-Guillemin ne-Storz angaba usizo. Omunye umehluko obalulekile ukuhambisana namahose ajwayelekile omlilo: i-Storz icishe ihlanganiswe yonke indawo kumafutha omfula aseYurophu, kuyilapho i-Guillemin ivame kakhulu ezinhlelweni ze-hydrant ezimile eFrance naseSpain, kanti i-Camlock ivame kakhulu ekuthuthweni kwamanzi kwezimboni nokwesikhashana. Uhlelo lokuvimba nalo luyahluka: i-Guillemin isebenzisa i-gasket ye-axial ecindezelwa inathi, i-Storz isebenzisa i-gasket eyisicaba ehlala endaweni ebaziwe, kanti i-Camlock isebenzisa i-radial lip seal ku-adapter yensikazi; ngayinye inezici zayo zokugqoka nokulula kokushintsha. Uma kucatshangelwa izinhlelo zomlilo, ikhono lokuxhuma nokukhumula ngaphansi komfutho nalo libalulekile – i-Storz ivumela ukuxhuma okulinganiselwe ngaphansi komfutho ophansi, kuyilapho i-Guillemin ngokuvamile kumele ikhishwe umfutho, kanti i-Camlock ingaxhunywa ngaphansi komfutho osele ngomklamo okhethekile. Ukukhethwa kwezinto kuthinta ngqo yonke le miphumela, ikakhulukazi isisindo, ukumelana nokugqwala, nokumelana nokushisa okuphezulu. Isibonelo, i-Guillemin yethusi inikeza amandla amahle kakhulu kodwa yengeza isisindo esikhulu emaphethelweni ehose, kuyilapho i-Storz ye-aluminium ilula kodwa ingase ingakwazi ukumelana nokuchayeka isikhathi eside emanzini olwandle noma amakhemikhali anamandla. Izinduna zomlilo nonjiniyela ngakho-ke kumele bahlole izidingo ezithile ze-hydraulic, izimo zemvelo, nezinqubo zokusebenza ngaphambi kokunquma ngezinga lokuxhuma.

Ukukhetha impahla efanele yama-couplings emaphrojekthini omlilo aseYurophu akugcini nje ngokuqhathanisa intengo; kudinga ukuqonda okujulile kwengcindezi yokusebenza, amazinga okushisa endawo, ukuchayeka kumakhemikhali, kanye nokuhambisana namazinga aseYurophu nawesizwe. Izinto eziyinhloko ezisetshenziswa ekwenzeni ama-couplings yi-aluminium, ithusi, insimbi engagqwali, kanye nama-thermoplastics obunjiniyela afana ne-polypropylene (PP) ne-nylon, ngayinye inikeza inhlanganisela eyingqayizivele yezakhiwo zemishini nokumelana nokugqwala. I-aluminium, evamise ukwenziwa nge-EN AC-42100 noma efanayo, ilula, imelana nokugqwala ezindaweni ezomile, futhi ingabizi kakhulu, okwenza ibe yinto ezenzakalelayo kuma-Storz nama-Guillemin couplings amaningi asetshenziswa ngaphezu komhlaba. Nokho, i-aluminium ingathinteka ukugqwala kwe-galvanic uma ithintana namapayipi e-copper-alloy noma ezinhlelweni zamanzi olwandle, ngakho kunconywa ukufakwa kwe-anodising noma i-coated finish evikelayo. Ithusi, ingxubevange yethusi ne-zinc, linikeza ukuqina okuhle kakhulu, ukumelana namazinga okushisa aphakeme, kanye nezakhiwo zemvelo zokungakhiqizi izinhlansi, okubalulekile ezindaweni ezingaba nokuqhuma njengezikhungo ze-petrochemical; nokho, ithusi linzima futhi libiza kakhulu kune-aluminium, futhi lingathinteka ukukhishwa kwe-zinc emanzini ane-chlorine ephezulu noma i-pH ephansi. Insimbi engagqwali, evamise ukuba yi-grade 316L, iyona nketho ehamba phambili emaphrojekthini omlilo adinga ukumelana nokugqwala okuphezulu kakhulu, ikakhulukazi ezindaweni ezisogwini, ezindaweni zasolwandle, noma lapho ama-fire suppression agents equkethe izithasiselo ezigqwalayo. Ama-couplings ensimbi engagqwali angamelana namazinga okushisa aphezulu kakhulu ngaphandle kokulahlekelwa ukuqina kwesakhiwo, okwenza afanelekele ukusondelana nemithombo yokushisa noma ezinhlelweni zokucisha umlilo zamazinga okushisa aphezulu. Ama-couplings e-polypropylene ne-nylon avela njengezinketho ezilula, ezimelana namakhemikhali, nakuba enemikhawulo ephansi yengcindezi namazinga okushisa futhi ngokuvamile ekhawulelwe ekusetshenzisweni endaweni evamile. Amaphrojekthi omlilo aseYurophu kumele ahambisane namazinga afana ne-EN 14420 yama-hose fittings nama-couplings, i-DIN 14330 ye-Storz, ne-NF S61-200 yemishini yomlilo yaseFrance, acacisa ubukhulu be-dimensional, amazinga engcindezi, nezinto ezisetshenziswayo. Ukwengeza, imithetho ye-REACH ithinta ukutholakala kwezinye izingxubevange, futhi izitifiketi zokuhlola – njengophawu lwe-CE noma ukugunyazwa kwe-TÜV – kungadingeka ekuthengweni komphakathi. Uma lezi zici zicatshangelwa ndawonye, ukukhetha impahla okufanele akugcini nje ngokuqinisekisa ukuphepha kwesistimu kodwa futhi kunciphisa izindleko zomjikelezo wokuphila ngokunciphisa ukugcinwa nokushintshwa njalo. I-Varicpand International inikeza uhla olugcwele lwezinto nezitifiketi, okuhlanganisa namakhasi athile,I-Aluminium Guillemin Coupling, I-Aluminum Storz Coupling, kanye I-Stainless Steel Guillemin Coupling, okuvumela amakhasimende ukuthi afanise ukusebenza kwezinto ezibonakalayo nezidingo zephrojekthi ngokunembile.

Ukuhlangana kwe-Guillemin sekuvele kwaziwa ngokuqina kwakho, futhi umklamo wamantongomane anentambo unikeza amandla okucindezela angalinganiswa yizinhlelo ze-bayonet noma ze-cam ngaphansi kokudlidliza okukhulu nokukhuphuka kwengcindezi. Ukuxhumana kungavimbi ukuvuza ngokwemvelo ngoba i-gasket icindezelwa ngokulinganayo nxazonke, futhi noma ngabe ukuxhumana kungahambisani kancane, intongomane idonsa izinhlangothi zombili ndawonye ngokulinganayo, ivimbele ukuvuza okuncane okuvame ukubonakala kwezinye izinhlelo zokuxhuma ngokushesha. Lokhu kwenza i-Guillemin ithembeke kakhulu emigqeni yokucisha umlilo enengcindezi ephezulu, njengalezo eziphakela ama-risers ezakhiwo noma izinhlelo ezinkulu ze-water cannon. Umklamo uvumela ukusetshenziswa kwezinto ezahlukahlukene ngaphandle kokunciphisa ukusebenza – ungakhetha i-aluminium elula empahleni ephathwayo, ithusi ezindaweni zokukhipha amanzi omlilo lapho ukuqina kubalulekile, insimbi engagqwali ezindaweni ezinogwaja olunamandla, noma ngisho ne-polypropylene ezinhlelweni zamakhemikhali okucisha umlilo. Enye inzuzo yikhono lokufeza izingcindezi zokusebenza eziphezulu kakhulu; ama-Guillemin couplings anamandla kakhulu angabamba kuze kufike ku-40 bar kwezinye izimo, okufanele amaphampu omlilo akhiqiza amandla amakhulu. Ngaphezu kwalokho, umklamo we-symmetrical male/female wenza izinto zokuthutha zibe lula, ngoba awudingi ukugcina ama-adapter ahlukene; ingxenye ngayinye iyafana, kunciphisa izindleko zokugcina impahla futhi kuqede ubungozi bokuxhuma izingxenye ezingahambelani. Ukunakekela kulula ngoba i-gasket ingashintshwa ngokushesha ngama-o-ring ajwayelekile atholakala kunoma yimuphi umthengisi, ngaphandle kwamathuluzi akhethekile. Ama-Guillemin couplings nawo anempilo yokusebenza ende uma enakekelwa kahle, futhi imicu yamantongomane ingagcotshwa kabusha ukuze iqhubeke isebenza kahle ngemva kwezinkulungwane zokuxhuma. Emabuthweni ezicishamlilo okungenzeka aqeqeshelwe i-Storz ngokwesiko, ukufunda akuthathi isikhathi eside, futhi amazinga ezobuchwepheshe aseYurophu afana ne-NF S61-200 achaza ngokucacile ubukhulu be-Guillemin, okuqinisekisa ukusebenzisana kwemishini yaseFrance neyaseSpain. Ekugcineni, ukuqina kwama-Guillemin couplings kubenza babe ukutshalwa kwezimali okuhlakaniphile ezingqalasizinda zokuvikela umlilo eziphikelelayo, ezinobuqotho obuphezulu lapho ukuthembeka kokusebenza kubaluleke kakhulu kunesivinini sokuxhuma.

Izihlanganisi ze-Storz zingamaqhawe angenakuphikiswa okuxhumana okusheshayo emsebenzini wokucisha umlilo, futhi umklamo wazo we-bayonet olinganayo usho ukuthi noma yiziphi izingxenye ezimbili ze-Storz – kungakhathaliseki ukuthi yiluphi uhlobo noma into – zihlangana kahle ngokuphenduka kwesihlakala ngekota, okuyisici esisindisa izimpilo esimweni esiyinkinga sendawo yomlilo. Ngenxa yokuthi akukho umehluko wesilisa/vesifazane, abacishi bomlilo bangaxhuma amapayipi avela kubakhiqizi abahlukene ngaphandle kokuzama ukuthola ukuphela okulungile, futhi indlela yokukhiya iyazivikela, igwema ukunqanyulwa okungazelelwe ngesikhathi sokunyakaza. Isivinini sokuxhuma sibalulekile nje: isihlanganisi esijwayelekile se-Storz singaxhunywa ngokugcwele ngaphansi kwemizuzwana emithathu uma kuqhathaniswa nemizuzwana emihlanu noma ngaphezulu kwe-Guillemin, futhi ngezandla ezigqokile umsebenzi ulula ngokufanayo. Izihlanganisi ze-Storz nazo zihambisana kakhulu namapayipi omlilo – cishe wonke amapayipi omlilo aseYurophu akhiwa namuhla afaka isixhumi se-Storz, ngakho ungaxhuma noma iliphi ipayipi kunoma iyiphi indawo yokukhipha yeloli. I-gasket eyisicaba ifihliwe futhi ivikelwe ekugqwaleni, inciphisa amathuba okuvuza futhi igcina ukuqina ngisho nangemva kwamakhulu emijikelezo yokuxhuma. Izihlanganisi ze-Storz zitholakala kabanzi nge-aluminium elula, okunciphisa ubunzima bomzimba kubacishi bomlilo, futhi umklamo owenziwe kahle awunazo izingxenye eziqhamukayo ezingabamba imfucumfucu noma izinhlangano zeminyango. Ngokombono wokuklama uhlelo, i-Storz ivumela ukufakwa kwama-dry risers, izindawo zokukhipha ama-hydrant, nokuxhunywa kwamaphampu ngesixhumi esisodwa esivamile, kwenze kube lula kokubili ukuthenga nokuqeqesha abasebenzi. Ngaphezu kwalokho, indlela yokuphenduka ngekota ingashintshwa ukuze isetshenziselwe izinsiza ezinomfutho ophezulu kuze kufike ku-16 bar ngesimo esijwayelekile, futhi izinhlobo ezithile zilinganiswa ku-25 bar ukuze kuvikelwe umlilo wezimboni. Ukuthandwa kwe-Storz kusho ukuthi izingxenye zokushintsha, ama-gasket, nezinsiza zokwengeza zitholakala kakhulu futhi zinamanani ancintisanayo kulo lonke elaseYurophu. Njengoba kucatshangelwa zonke lezi zici, i-Storz ihlala iyisinqumo esikhethwayo emabuthweni omcishomlilo kamasipala, ezinhlelweni zokucisha umlilo zezimboni, nasezingxenyeni ezihambayo zokucisha umlilo, futhi i-Varicpand ihlinzeka ngohlu olukhethekile lwe-Ukuxhuma Kwe-Storz Yethusi kanye nezinye izinketho zempahla ukuze kuhlangatshezwane yonke imfuneko yokusebenza.

Ama-coupling e-Camlock aletha izinga lokuguquguquka okungafaniswa ne-Guillemin noma i-Storz, ikakhulukazi ngenxa yobubanzi obukhulu bemikhiqizo nezinto ezitholakalayo – kusukela kuma-adapter amancane angu-12 mm asetshenziswa emapayipini aselabhorethri kuya kumasistimu amakhulu okudlulisa angu-600 mm. Lokhu kuguquguquka kwenza i-Camlock ibe ikahle ezindaweni zokuhlinzeka ngamanzi, emigqeni yokuzivikela yokucisha umlilo yesikhashana, nanjengezixhumanisi phakathi kwezimoto zomlilo namasistimu amahydrant agxilile lapho kudingeka ukuhambisana ne-ASME noma amanye amazinga ezimboni. Umakhenikha we-cam-arm uvumela ukuxhumana okuphephile ngaphandle kwesidingo sanoma yimaphi amathuluzi, futhi ukuxhumana kungenziwa futhi kuhlukaniswe ngaphansi kwemizuzwana emibili, okwenza kube ukushesha kakhulu kwezinhlobo ezintathu, okubalulekile ezimweni zokushintsha ngokushesha ukuhlelwa kwamapayipi. Ama-coupling e-Camlock nawo abiza kakhulu, ngamamodeli e-aluminium anenani eliphansi kakhulu eliheha izinkontileka ezigxile kwisabelomali nasezinhlelweni lapho ama-coupling engalahleka noma entshontshwa. Ubulula bomklamo benza ukulungiswa kube lula – i-gasket iyindingilizi ejwayelekile ye-‘O-ring’ noma iphrofayili eyisicaba engashintshwa ngemizuzu embalwa, futhi izingalo ze-cam zingaqiniswa kalula uma zixega. Enye inzuzo ukuhambisana nezinhlobonhlobo zezinto ze-gasket (NBR, EPDM, Viton, PTFE) ukuze kumelwe amagwebu ahlukene okucisha umlilo, izinto zokumanzisa, noma amakhemikhali angajovwa emanzini. Ama-coupling e-Camlock nawo alula futhi aminyene, okwenza kube nokwenzeka ukukhipha osayizi abaningi kukho kokubili ipulasitiki nensimbi, futhi umklamo uye wafakazelwa emashumini eminyaka ekudlulisweni koketshezi ezimbonini, ngakho ukukhetha okuthembekile kwezindawo zokugcina amanzi omlilo namapayipi okudonsa amanzi. Nokho, emigqeni eyinhloko yokuletha izinsiza zomlilo, izinga eliphansi lokucindezela le-Camlock ejwayelekile (imvamisa i-10 bar) lingaba umkhawulo, kodwa izinguqulo ezinzima ezenziwe ngensimbi engagqwali zingakwazi ukubhekana nokucindezela okuphezulu. I-Varicpand inikeza uhla oluphelele lwezinsiza ze-Camlock nezinye izindlela, ezifana ne-Ukuxhuma Kwe-Camlock Kwe-Stainless Steel, ukusekela amaphrojekthi adinga ukuguquguquka kwalolu hlelo.

Naphezu kwezinzuzo zazo eziningi, uhlobo ngalunye lokuxhuma lunezinkinga ezithile okumelwe zihlolwe ngokucophelela ngokuqondene namaphrojekthi omilio waseYurophu, futhi ukuziba lezi zinkinga kungaholela ekwehlulekeni kokusebenza noma ezingozini zokuphepha. Ama-Guillemin couplings, nakuba eqinile, athatha isikhathi eside ukuxhunywa kune-Storz noma i-Camlock, futhi i-threaded ring nut ingavimbanwa yiqhwa, isihlabathi, noma ukungcola komgwaqo, kuvimbele ukuvaleka okuqinile ngesikhathi esiphuthumayo. Ukwengeza, i-nut ephumayo yengeza ubukhulu, futhi izingxenye ezimbili ezilinganayo zokuxhuma zincike ekulinganeni okunembile kwe-gasket; noma yikuphi ukuphambuka okubangelwa ukushisa okuphezulu noma amakhemikhali anamandla kungadala ukuvuza. Ama-Storz couplings, nakuba ashesha, anomkhawulo wokucindezela – amazinga ajwayelekile we-16-bar angase anganele ezakhiweni eziphakeme kakhulu lapho amaphampu omilio ekhiqiza ngaphezu kwe-20 bar, edinga izinhlobo ezikhethekile zokucindezela okuphezulu ezibiza kakhulu. Futhi, ama-bayonet prongs angagqoka ngokuhamba kwesikhathi, okuholela ekungazinzeni ekuxhumekeni, futhi i-flat gasket kumelwe iqondaniswe kahle; i-gasket engaqondaniswanga ingaphuma ngenxa yokucindezela. Ama-Camlock couplings, nakuba eguquguquka, abhekana nenkinga yokuthi kudingeka izingxenye zombili zesilisa nezesifazane, ngakho okugcinwayo kumelwe kulawulwe ngokucophelela ukuze kugwenywe ukushoda, futhi ama-cam levers asengozini yokuvuleka ngengozi uma ebamba eminye imishini. Izinga lokucindezela lama-Camlock ajwayelekile liphansi, ngakho awafaneleki emigqeni yokuhambisa enomfutho ophezulu omile noma lapho kulindeleke i-water hammer, futhi i-gasket iveziwe engxenyeni yesifazane, okwenza kube lula ukulimala ngenxa yokuxhunywa okomile noma izinto ezibukhali. Enye inkinga evamile ukungafani kwamazinga: nakuba i-Storz ne-Guillemin zibhalwe emazingeni kazwelonke naseYurophu, ama-Camlock couplings avame ukuhambisana namazinga ezimboni (isb., MIL-C-27487), okungenzeka angamukelwa yiziphathimandla ezithile zomlilo. Ukwengeza, ezindaweni ezibandayo kakhulu, zontathu izinhlobo zokuxhuma zingaba yiqhwa, futhi ama-gasket angaba lukhuni, adinge ukushisisa ngaphambilini noma izinqubo ezisheshisiwe zokunakekela. Ekugcineni, ukukhetha impahla kunganciphisa ezinye izinkinga kodwa kuletha ukushintshana okusha: ngokwesibonelo, i-aluminium Camlock ilula futhi ishibhile kodwa igqwala ngokushesha emanzini anosawoti, kuyilapho i-stainless steel Guillemin imelana nokugqwala kodwa inzima kakhulu futhi ibiza kakhulu. Ngakho-ke, ukuhlolwa okuphelele kwezingozi kumelwe kwenziwe ngaphambi kokuzibophezela kunoma yiluphi uhlelo lokuxhuma, futhi kuyelulekwa ukuthintana nabahlinzeki abafana ne-Varicpand abangahlinzeka ngedatha yobunjiniyela eqhathanisayo kanye nolwazi lwangempela lokufakwa.

Sikhwathi futhi sinendawo enkulu yokugcina izingxenye zokushintsha nama-gasket, siqinisekisa ukuthi izinhlelo zakho zomlilo zihlala zisebenza ngaphandle kokuphazamiseka okuncane. Ukuthembeka kwenkampani kubonakala ebudlelwaneni obude nabasabalalisi bemishini yomlilo, abeluleki bezobunjiniyela, kanye nezinhlaka zikahulumeni kulo lonke elaseYurophu, bonke abathemba imikhiqizo yeVaricpand ezinhlelweni zokuphepha kwempilo. Ngokumboza okuphelele kwezinsiza – kusukela kumakhava othuli kuya kuma-adaptha wamapayipi – siyisitolo esisodwa, senza kube lula ukuthola izinto zakho nokuhlanganisa umthombo wakho wokuhlinzeka. Ukuze ubone ububanzi obugcwele bamakhono ethu futhi ubuke imigqa yethu yemikhiqizo, sicela uvakashele i-Imikhiqizo ikhasi, noma xhumana nethimba lethu nge-Xhumana ikhasi lokuxoxa ngemidingo yakho yephrojekthi yomlilo ngemininingwane.

Ukukhetha phakathi kwe-Guillemin, Storz, kanye ne-Camlock couplings ngephrojekthi yomlilo yaseYurophu akusona isinqumo esilula, ngoba kuthinta ngqo ukusebenza kahle, ukuphepha, kanye nezindleko zokunikela ngempahla. I-Guillemin couplings inikeza ukuqina okuphezulu nokungavuzi kwamanzi okuphelele ezikhungweni ezinomfutho ophezulu, ikakhulukazi emasikweni okucisha umlilo aseFrance naseSpain, kuyilapho i-Storz couplings inikeza ukuxhumana okusheshayo kwekota yokujika kanye nokuhambisana okujwayelekile namapayipi omlilo, okwenza kube ukukhetha okuyisisekelo emabuthweni amaningi aseYurophu. I-Camlock couplings iletha ukuguquguquka nezindleko eziphansi, kodwa izinga layo lomfutho eliphansi kanye nesidingo sokuthi abesilisa nabesifazane babhanqwe ngokufanele kuvame ukubakhawulela emigqeni yokudonsa amanzi, ukuxhumana kwesikhashana, noma izinhlelo zamanzi omlilo zezimboni. Ukukhetha kwempahla kuyisisekelo esibalulekile: i-aluminium ilula futhi ingabizi, ithusi linikeza amandla nokungakhiqizi izinhlansi, insimbi engagqwali inikeza ukuvikelwa okuphezulu kakhulu ekugqwaleni, futhi amapulasitiki obunjiniyela anikeza ukumelana namakhemikhali, futhi impahla ngayinye isebenza ngendlela ehlukile ngomfutho, izinga lokushisa, nokuchayeka emvelweni. Ngokuhambisa izinga lakho le-coupling nempahla efanele – nokuqinisekisa ukuthobela i-EN, i-DIN, namakhodi kazwelonke omlilo – ungakha uhlelo lokuvikela umlilo olusebenza ngokuthembekile iminyaka eminingi. Kumthengisi osunguliwe onohlu olubanzi nobuchwepheshe bobunjiniyela,IVaricpand Internationalimisukulwe ukusekela iphrojekthi yakho kusukela ekuklanyweni kuze kufike ekugqibeleni. Siyakumema ukuthi usebenzise ulwazi lwethu lomkhiqizo, amandla ethu okukhiqiza ngokwezifiso, kanye nochungechunge lwethu lokunikezela oluthembekile ukuze wenze iphrojekthi yakho elandelayo yomlilo ibe yimpumelelo. Khumbula ukuhlola izidingo zakho ze-hydraulic, ukubonisana neziphathimandla ezifanele zomlilo, futhi ucele amasampula ukuze uhlole i-prototype ngaphambi kokwenza isinqumo sokugcina. Ngokuhlanganisa okufanele kanye nezinto ezifanele, ungazuza ukusebenza okungenazihibe, okuphephile, nokusebenza kahle kokucisha umlilo kulo lonke elaseYurophu.

Umehluko omkhulu phakathi kwe-Guillemin, Storz, ne-Camlock usezindleleni zokuxhuma namandla okucindezela. I-Guillemin isebenzisa i-ring nut enemicu enikeza ukuvala okuqinile, okuphezulu kakhulu kokucindezela kodwa kuthatha isikhathi eside ukuxhuma, kanti i-Storz isebenzisa i-quarter-turn bayonet action esheshayo futhi elinganiselayo, okwenza ifaneleke kakhulu emapayipini omilio. I-Camlock isebenzisa ama-cam levers agoqeka phezu komsele, inikeza ukuxhuma okushesha kakhulu kodwa inamazinga aphansi wokucindezela ajwayelekile futhi idinga ama-adaptha ahlukene abesilisa nabesifazane. Emaphrojekthini omilio, i-Storz ivame ukuhlanganiswa ezinhlelweni zamapayipi omilio, i-Guillemin ikhethwa ekufakweni okuqinile kokucindezela okuphezulu, kanti i-Camlock ifanele ukudluliswa kwamanzi kwesikhashana noma kwezimboni.

Izinto ezinhle kakhulu zincike endaweni lapho usebenzisa khona. Ezinhlelweni ezijwayelekile zomlilo zikamasipala, ama-aluminium Guillemin couplings anikeza isisindo esilula, isixazululo esingabizi kakhulu esinokumelana nokugqwala okwanele ezimweni ezomile noma zamanzi ahlanzekile. Ezindaweni ezisogwini noma lapho kungenzeka ukuchayeka emanzini olwandle, i-stainless steel 316L inikeza ukumelana nokugqwala okuphezulu kakhulu namandla emishini amahle kakhulu, nakuba isinda futhi ibiza kakhulu. I-Brass ingenye inketho lapho kudingeka izakhiwo zokungakhiphi izinhlansi nokuqina okuphezulu, ikakhulukazi ekucimeni umlilo kwamaphethroliyumu namakhemikhali. Uhlu olugcwele lwezinto lungabuyekezwa ekhasini lomkhiqizo we-Guillemin elinikezwe yi-Varicpand.

Izingxube ze-Storz ezijwayelekile zivame ukukalwa zifinyelele ku-16 bar, kodwa izinhlobo ezinzima ezinokwakheka okuqinisiwe nezinto eziqinile, njengensimbi engagqwali noma i-aluminium eqinisiwe ngokukhethekile, zingaphatha izingcindezi eziphakeme ezifinyelela ku-25 bar noma ngaphezulu. Uma uhlelo lwakho lokucisha umlilo ludinga izingcindezi zokusebenza ezingaphezu kuka-16 bar, kufanele uqinisekise isilinganiso sokucindezela semodeli ethile ye-Storz futhi uhlole amashidi edatha omkhiqizi. Izindinganiso zaseYurophu zezixube ze-Storz, ezifana ne-DIN 14330, zicacisa izigaba zokucindezela, ngakho khetha isixube esiqinisekisiwe ukuze sihambisane nomfutho wakho omkhulu wokusebenza.

Ama-coupling e-Camlock ngokuvamile awanconozwa ukuthi asetshenziselwe ukuxhumana okujwayelekile kwezimpompi zomlilo, ngoba izinhlelo eziningi zezimpompi zidinga amazinga okucindezela adlula amabhawa angu-10–12 ajwayelekile ama-aluminium Camlock coupling. Ngaphezu kwalokho, izinsiza zomlilo zivame ukuphoqa ukusetshenziswa kwama-coupling azwakalayo kazwelonke (anjenge-Storz noma i-Guillemin) ukuze kuqinisekiswe ukuhambisana namahose omlilo. Nokho, ama-Camlock coupling avame ukusetshenziselwa imigqa yesikhashana yokuhambisa amanzi, amahose okudonsa amanzi, noma njengama-adaptha eziteshini zokugcwalisa izimoto zomlilo, lapho ukucindezela okuphansi nokunqanyulwa okusheshayo kwamukelekile.

Ukukhetha impahla kuyisici esibalulekile esinquma isikhathi sokuphila kokuxhuma ngoba kulawula ukumelana nokugqwala, ukugqwala, izinga lokushisa elidlulele, nokukhathala kwemishini. Ama-coupling e-aluminium angagqwala ezindaweni ezinomswakama noma ezinosawoti ngaphandle kokuthi afakwe ukumboza, kuyilapho ama-coupling ensimbi engagqwali ecishe aqede ukugqwala futhi angahlala iminyaka eminingi, ngisho nasezindaweni ezisogwini. Ithusi liqinile kodwa lingahoxa emanzini ane-chloride ephezulu, futhi ama-coupling epulasitiki asengozini yokonakala yi-UV nokulimala komthelela. Ukukhetha impahla ehambisana nezimo zakho zemvelo namakhemikhali kunciphisa izidingo zokunakekela futhi kunwebe isikhathi sokusebenza saso sonke isistimu yomlilo.

Kumaphrojekthi omilio waseYurophu, amazinga afanele kakhulu yi-EN 14420 yezixhumi zamahose nama-couplings, ehlanganisa izidingo zobukhulu nokusebenza, kanye ne-DIN 14330 ngokuqondile yama-Storz couplings. Amasistimu omilio aseFulansi ama-Guillemin avame ukubhekisela ku-NF S61-200, echaza ubukhulu namazinga okucindezela. Ama-Camlock couplings avame ukwenziwa ngokwe-MIL-C-27487 noma i-EN 14420-7 ezimweni ezibucayi zokuphepha. Hlala uqinisekisa ukuthi ama-couplings akhethiwe anophawu olufanele lwe-CE futhi ahlangabezana nemithetho yeziphathimandla zomilio zendawo.

Yebo, kungenzeka ngokobuchwepheshe ukuhlanganisa ama-Guillemin nama-Storz couplings ngaphakathi kohlelo olulodwa lokuvikela umlilo, kodwa kufanele usebenzise ama-adaptha okuguqula afanisa ngokunembile izinhlobo ezimbili zemisonto noma amaphethini e-bayonet. Nokho, ukuhlanganisa amazinga kukhulisa ubunkimbinkimbi bokusungula impahla futhi kudinga ukuba abasebenzi baqeqeshwe kuzo zombili izinhlobo zokuxhuma, okungase kubambezise ukusabela okuphuthumayo. Kuvame ukuba nempumelelo enkulu ukwenza okukodwa kube okujwayelekile ngohlelo ngalunye noma ngendawo yesevisi yomlilo, futhi kusetshenziswe ama-adaptha kuphela ezindaweni ezibalulekile ezifana nokuxhuma kwemibhobho yamanzi noma ukuxhuma kwamaloli.

Izimbotshana zensimbi engagqwali, ikakhulukazi lezo ezenziwe nge-316L, ngokuvamile zibiza kathathu kuya kahlanu ngaphezu kwezimbotshana ze-aluminium ezilinganayo ngenxa yezindleko zempahla eluhlaza kanye nezinqubo eziyinkimbinkimbi zokwenza. Umehluko wentengo uyahlukahluka ngosayizi nomkhiqizi, futhi ububanzi obukhulu bukhombisa umehluko omkhulu nakakhulu. Nakuba i-aluminium ingabiza kancane ekuqaleni, insimbi engagqwali inganikeza izindleko eziphansi zomjikelezo wokuphila wonke ezindaweni ezinokugqwala ngokunciphisa ukunakekela nokuvuselelwa njalo. Kumaphrojekthi abucayi ngebhajethi, kungasetshenziswa indlela ehlanganisiwe: i-aluminium yemishini ephathwayo engaphezulu komhlaba kanye nensimbi engagqwali yokuxhumana okungapheli, ezindaweni ezinzima.
