Lapho kwakhiwa noma kuthuthukiswa uhlelo lokuvikela umlilo eYurophu, ukukhetha kwe-coupling kungabonakala kuyimininingwane encane, kodwa kunganquma umehluko phakathi kokuphendula okuphumelelayo okuphuthumayo nokwehluleka okuyinhlekelele. Onjiniyela nochwepheshe bokuthenga ezwenikazi lonke bavame ukubhekana nenselelo yokukhetha phakathi kwe-Guillemin, Storz, nama-camlock couplings, ngayinye inikeza izinzuzo ezihlukile zokuxhumana kwamanzi omlilo. Izinto ezakhiwa ngazo la ma-couplings zidlala indima ebaluleke kakhulu ekusebenzeni, ekuphileni isikhathi eside, nasekuphepheni ngaphansi kwezimo zokusebenza ezinzima. I-Aluminium, ithusi, nensimbi engagqwali yizinketho ezivelele, futhi ngayinye iletha isethi ehlukile yezakhiwo zemishini namakhemikhali. Lesi sihloko sinikeza ukuqhathanisa okuningiliziwe kwalezi zindlu ezintathu zama-couplings ikakhulukazi kumaphrojekthi omLilo aseYurophu, ngokugxila okukhulu ekukhetheni izinto ze-coupling. Njengomhlinzeki ohamba phambili embonini,Mayelana Nathi amakhasi e-Varicpand International abonisa inkampani ezinikele ekusekeleni onjiniyela ngezingxenye zekhwalithi ephezulu nobuchwepheshe obuqondene nezidingo zokuvikela umlilo.

Imisebenzi yokucima umlilo yaseYurophu ihlelekile kakhulu, kodwa imishini esetshenziswayo emingceleni yamazwe ahlukene ayifani nhlobo, okwenza ukuqonda kwezindinganiso zokuxhuma ngakunye kube semqoka. Ama-Guillemin couplings amukelwa kabanzi eFulansi nakwezinye izimakethe ezimbalwa ezikhuluma isiFulentshi, kuyilapho ama-Storz couplings egqama eJalimane, e-Austria, eSwitzerland, nasezifundazweni zaseScandinavia. Ama-Camlock couplings, ngakolunye uhlangothi, enza umsebenzi owezimboni kakhulu, evame ukuvela kumaphampu, emathangeni, nasemigqeni yokudlulisa izinto ezinkulu ezisekela izinhlelo zokucisha umlilo. Ukuxhunywa kwamanzi okucima umlilo kumele kumelane nokukhuphuka komfutho ophezulu, ukudlidliza okuqhubekayo, kanye nemijikelezo yokuxhuma nokukhumula evamile, okubeka ingcindezi enkulu emzimbeni nasezintweni zokuvala. Ukukhetha ama-couplings afanele okucima umlilo kudinga ukuqonda okujulile kwezimo zokusebenza, izindinganiso zaseYurophu ezisebenzayo, kanye nezindleko zokuphila kwempilo yomkhiqizo. Ezigabeni ezilandelayo, sihlola uhlobo ngalunye lwe-coupling ngokujulile futhi siveza imibandela eqondisa ukukhethwa kwezinto ezifanele zama-fire hose couplings nemishini ehlobene nayo.

I-Guillemin coupling, eyaziwa nangokuthi i-symmetrical instantaneous coupling, inomklamo ohlukile onezingxenye ezimbili ezifanayo ezihlangana ngama-lug avumelanayo kanye neringi lokukhiya elisebenza nge-lever, okwenza kube i-quick connect coupling yangempela. Lo mklamo uthandwa kakhulu ezinkonzweni zomlilo zaseFrance, lapho ufakwa emapayipini, ezindaweni zokukhipha amanzi (hydrant outlets), nasezindaweni zokumpompa amanzi nsuku zonke, futhi ukuthembeka kwawo kufakazelwe emashumini eminyaka yokusebenza. Ukuvumelana komklamo kusho ukuthi noma yimuphi umkhawulo ungaxhuma komunye, okwenza kube lula kakhulu ukuphatha ebumnyameni, entuthwini eminyene, noma ngesikhathi sokucindezela okukhulu lapho ukubona kungasebenzi kahle. Ama-Guillemin couplings ngokuvamile akhiwa nge-aluminium, ithusi (brass), noma insimbi engagqwali (stainless steel), futhi uhlobo ngalunye lwezinto lukhethwa ngokusekelwe endaweni yokusebenza elindelekile kanye nezinga lokucindezela elidingwa ukusetshenziswa. Izinhlobo ze-aluminium zinika isilinganiso esihle kakhulu sokuqina nesisindo ekuphatheni amapayipi ngesandla, kuyilapho ithusi nensimbi engagqwali zikhethwa ezindaweni ezinokugqwala noma ezishisayo lapho ukuqina kwesikhathi eside kubalulekile. I-Varicpand International ihlinzeka ngohla oluphelele lwe-Guillemin Couplings ngezinhlobonhlobo zezinto, kuqinisekisa ukuthi yonke insiza yokuvikela umlilo ingafakwa ngengxenye efanele.

Ama-Storz couplings asungulwa nguGuido Storz ngo-1882 eJalimane futhi asalokhu eyizingxenye ezijwayelekile zokuxhuma amapayipi omlilo emazweni amaningi asenkabeni nasenyakatho yeYurophu, okuwubufakazi bokuklama kwazo okuhle okuhlala njalo. Ukuklanywa kusebenzisa izingxenye ezimbili ezilinganayo ezinama-lug agobile ahlangana ndawonye ngokuphenduka okulula kwekota, okwakha ukuxhumana okusheshayo nokuphephile ngisho nasezimeni ezinzima kakhulu. Ama-Storz couplings aziwa ngokusebenziseka kalula, futhi abacimi bomlilo bangaxhuma amapayipi ngemizuzwana nje ngisho begqoke amagilavu avikelayo aminyene noma besebenza ezindaweni ezincane. Lawa ma-fire hose couplings akhandwa noma acastwe nge-aluminium, ithusi, noma insimbi engagqwali, kanti i-aluminium ekhandiwe iyona ekhethwa kakhulu emishinini yezimo eziphuthumayo ngenxa yokuba lula kwayo nokuqina kwayo okuhle kakhulu. Ubukhulu obujwayelekile bama-Storz couplings buvumela ukusebenzisana phakathi kwemishini yabakhiqizi abahlukene, okubalulekile ekusizeni okuhlangene emingceleni yezifunda nezizwe ngezikhathi zezigameko ezinkulu. Noma kusetshenziswa kuma-hydrants, kuma-standpipes, noma ekuxhumaneni kwamaphampu emoto yomlilo,Storz Couplings ukuletha ukusebenza okuthembekile okuthenjwe yizinsiza zomlilo zaseYurophu iminyaka engaphezu kwekhulu, futhi uhla lubuye luhlanganise ezikhethekile I-Aluminum Storz Coupling izinketho zamaqembu acabangela isisindo.

Ama-camlock couplings ahluke kakhulu kumadizayini kaGuillemin noStorz ngoba awalingani, enziwe nge-male adaptor ne-female coupler ahlanganiswa kusetshenziswa izingalo ezimbili noma ezintathu ze-cam ohlangothini lwe-female, okudala indlela yokukhiya esebenza nge-lever-action ehlukile. I-lever action yezingalo ze-cam ivumela ukuxhuma nokuhlukanisa ngokushesha okukhulu ngaphandle kwesidingo sanoma yimaphi amathuluzi, okwenza ama-camlocks abe yintandokazi ezinhlelweni zokudlulisa uketshezi ezimbonini lapho isivinini nokulula kubaluleke kakhulu. Emongweni wokuvikela umlilo, ama-camlock couplings avela kuma-pump intakes ezimoto zomlilo, amaphampu aphathwayo, izinhlelo ze-foam proportioning, nemigqa yokuhambisa amanzi eminingi lapho kusetshenziswa amahose anobubanzi obukhulu ukuhambisa amanzi amaningi. Akhiqizwa nge-aluminium, i-stainless steel, ithusi, ne-polypropylene, futhiI-Camlock Coupling Yensimbi Engagqwali kube ukukhethwa okuthandwayo kumakhemikhali anamandla kanye nezindawo zasolwandle ezonakalisayo. Umklamo olula we-Ukuxhuma kweCamlock okwenza kube lula ukukugcina nokukushintsha endaweni, okuyinzuzo enkulu emaqenjini omilio kamasipala nawemboni ngokufanayo. I-Varicpand International inikeza uhlu olubanzi lwezinto zokuxhuma ze-camlock nezinsiza ezihlangabezana nezidingo eziqinile zamaphrojekthi omilio aseYurophu anamuhla.

Ukukhetha impahla efanele ye-fire protection coupling akukona ukuzivocavoca okulula, futhi kunezici eziningi ezibalulekile okumelwe zicatshangelwe ngaphambi kokuthi kuthathwe isinqumo sokugcina, ngoba iphutha lingabeka engcupheni kokubili ukuphepha nokulungela kokusebenza. Izidingo zomfutho ziza kuqala, ngoba i-coupling esebenza kahle kumfutho ophansi ingase yehluleke ngendlela eyingozi uma ibhekene nomfutho ophezulu wokukhipha okhiqizwa amaphampu omlilo anamuhla, avame ukudlula amabhawa ayi-10. Ukumelana nokugqwala kubaluleke ngokulinganayo, ikakhulukazi koxhumo lwamanzi omlilo oluchayeke kumswakama, usawoti womgwaqo, izithasiselo zamakhemikhali, noma amanzi anosawoti ezindaweni ezisogwini, lapho izinto zokufaka ezingavikelwe zingonakala ngokushesha. Ukuhambelana nezinga lokushisa nakho kubalulekile, ngoba ama-elastomer seals kanye nempahla yomzimba kufanele kusebenze ngokuthembekile kulo lonke uhla lwamazinga okushisa atholakala ezimweni zaseYurophu, kusukela ebusika obubandayo kuya ezinsukwini ezishisayo zasehlobo. Isisindo nokusebenza kahle komzimba kuvame ukunganakwa kodwa kubaluleke kakhulu, ngoba abacimi bomlilo kufanele bathwale futhi baxhume amahose ngaphansi kwengcindezi enkulu yomzimba, futhi i-brass coupling esindayo ingasheshe ibangele ukukhathala futhi ibambezele ukusebenza. Emizimbeni ye-aluminium, kufanele kunakwe ngokucophelela i-anodising nokukhethwa kwe-alloy, kanti kwi-stainless steel, izinga kufanele liqinisekiswe ukuthi linikeza ukuvikelwa kwangempela ekugqwaleni kwe-pitting nokugqwala kwemifantu.

Ukuthobela izindinganiso zaseYurophu kuyimfuneko engenakuphikiswa kunoma yisiphi isixhumi esisetshenziswa ekuvikelweni komlilo, futhi onjiniyela kumele baqinisekise ukuthi izingxenye zihlangabezana nezindinganiso ezifanele ze-EN, njenge-EN 14420 yezixhumi zamahose kanye ne-ISO 14565 yezixhumi zamapayipi omlilo, kanye nemithetho kazwelonke lapho kufanele khona. Ukonga izindleko nokubaluleka komjikelezo wokuphila nakho kumele kucatshangwe, ngoba isixhumi se-aluminium esishibhile singadinga ukushintshwa masinyane kakhulu kunesimo sensimbi engagqwali esibizela kancane uma sivezwe ezintweni ezigqwala noma ukuphathwa kanzima okuvamile. Ukutholakala kwezinsimbi zokushintsha kanye nokulula kokulungisa ensimini kumele kube nomthelela esinqumweni njengoba kunjalo ngentengo yokuthenga yokuqala, ngoba ukuma komsebenzi enkonzweni yomlilo akwamukeleki nhlobo. Empeleni, ukukhethwa kwezinto zokuxhuma kumaphrojekthi omlilo aseYurophu kuvame ukuthanda i-aluminium ekhohlisiwe yokusetshenziswa okujwayelekile, insimbi engagqwali yezindawo ezinzima, kanye nethusi lezinhlelo ezidinga ukumelana nokugqwala okuhle kakhulu nokukwazi ukusebenza kahle. Lapho kuhlolwa lezi zici, amaqembu okuthenga kumele asebenze nozakwethu oqonda kokubili ubuchwepheshe kanye nesimo somthetho, futhi i-Varicpand International ihlinzeka ngezinto ezibhalwe ngokugcwele futhi eziqinisekisiwe zokusetshenziswa kwezinsizakalo zomlilo ezwenikazi lonke.

Uma kuqhathaniswa imikhakha emithathu yokuxhuma eceleni kweyodwa, kuvela umehluko obalulekile ngejubane lokuxhuma, amandla okumelana nokucindezela, ukusebenza kokuvimba ukuvuza, nokuqina kwesikhathi eside, futhi lomehluko unomthelela oqondile ekukhetheni ukuthi iyiphi i-coupling ekhethelwa umsebenzi ngamunye. Mayelana nejubane lokuxhuma, ama-camlocks ngokuvamile ashesha kakhulu ukusebenza ngoba izingalo zama-cam zidinga nje ukuphonswa phansi, kanti ama-Storz couplings adinga ukujika kwengxenye yesine futhi ama-Guillemin couplings adinga ukuthi iringi ye-lever ibandakanywe, okungathatha isikhathi esincane ngaphezulu. Nokho, ukwakheka okulinganayo kwe-Storz ne-Guillemin kunenzuzo enkulu kwezokusebenza, ngoba zingaxhunywa ngokungaboni kahle ngaphandle kwesidingo sokuqondanisa isiphetho sowesilisa nowesifazane, okubaluleke kakhulu ezindaweni ezigcwele intuthu lapho ukubonakala kucishe kungabikho. Izinga lokucindezela liyahlukahluka ngosayizi, impahla, nomkhiqizi, kodwa ama-aluminium nama-stainless steel couplings akhiwe kahle ngokuvamile abamba izingcindezi zokusebenza ezihambisana ngokugcwele nokuphuma kwamandla ezimpompi zomlilo ezijwayelekile kanye nezingcindezi zokuhlinzekwa kwama-hydrant. Ukuhambisana kwe-seal kungenye into ehlukanisayo, ngoba izinketho ze-elastomer, ezifana ne-NBR, i-EPDM, ne-Viton, kufanele zikhethwe ukuze zihambisane namakhemikhali amanzi omlilo, ububanzi bezinga lokushisa le-ambient, nanoma yiziphi izinto ezigxilile zamagwebu ezisetshenziswa ohlelweni.

Izimfuneko zokuqina nokunakekela zihluka kakhulu phakathi kwezinhlobo ezintathu zokuxhuma kanye nezinto ezitholakalayo, futhi lezi zici kufanele zifakwe esibalweni sezindleko zokuphila kwesistimu yokuvikela umlilo. Ama-Guillemin couplings, ngemishini yawo yamalever nama-spring, adinga ukuhlolwa ngezikhathi ezithile ukuze kuqinisekiswe ukuthi isenzo sokukhiya sihlala sicacile futhi siyithembekile, ngoba ukuguga kunganciphisa amandla elever ngokuhamba kwesikhathi. Ama-Storz couplings aqine kakhulu futhi adinga ukunakekelwa okuncane, okuyisizathu esisodwa esenza abe yizinga legolide emisebenzini yezomlilo yaseYurophu, lapho ukuthembeka kubaluleke kakhulu kunakho konke. Ama-Camlock couplings anezingxenye ezinyakazayo ezimbalwa futhi kulula kakhulu ukuwakhandela endaweni yokusebenza, kodwa ancike kuma-gasket okufanele ashintshwe ngezikhathi ezithile ukuze kugcinwe ukuvala okungavuzi, futhi izingalo zama-cam kufanele zihlolwe ukuguga. Uma kukhulunywa ngokufaneleka kwamaphrojekthi omlilo aseYurophu, zontathu lezi zinhlobo zindawo yazo, ngoba i-Storz ihamba phambili ekusetshenzisweni kwamapayipi omlilo avamile, i-Guillemin ibalulekile ezinhlelweni zaseFrance, futhi ama-camlocks agqama ohlangothini lwezimboni nolwezinsimbi ezinkulu zokuhambisa amanzi. Ukuxhunywa kwemibhobho yomlilo, ukuxhunywa kwamaphampu ezimoto zomlilo, kanye nezinhlelo zezimboni zokuvikela umlilo ngakunye kunezimfuneko ezihlukile ezinomthelela ekukhetheni kokugcina kwe-coupling nezinto, futhi isiqondiso somthengisi onolwazi sibaluleke kakhulu ekwenzeni isinqumo esifanele.

I-Varicpand International isisungule ukuthi ingumhlinzeki othembekile wamajoyinti okuvikela umlilo kanye nezinsiza ezihlobene emakethe yaseYurophu, idume ngempahla ekhethekile kanye nekhwalithi engaguquki abanikazi bomsebenzi abathembela kuyo ezinhlelweni ezibalulekile. Inkampani ikhetha izinto zokusetshenziswa ezisezingeni eliphezulu, okuhlanganisa i-aluminium ebunjiwe, insimbi engagqwali ye-AISI 316, kanye nethusi lezinga eliphezulu, iqinisekisa ukuthi lonke ijoyinti lihlinzeka ngamandla emishini kanye nokumelana nokugqwala okudingekayo emsebenzini obalulekile womlilo ezindaweni ezinzima. Kukhona izinketho ezahlukahlukene zokuvala, okuhlanganisa i-NBR, i-EPDM, i-Viton, nama-elastomer asezingeni lokudla, ukuze amakhasimende akwazi ukufanisa ukuvala noketshezi olunembile kanye nezimo zokushisa zohlelo lwawo oluthile. Ukulinganisa ngendlela oyifunayo, ukuthungwa kwentambo, kanye nokuhlelwa kwe-flange kuyasekelwa, okusho ukuthi noma izixhumanisi zomlilo ezingajwayelekile zingaklanywa ngokucacile ngaphandle kokuphazamisa ikhwalithi noma ukuphepha. Lokhu kuzibophezela ekwenzeni ngendlela oyifunayo, kuhlanganiswe nokuhambisana nemithetho emikhulu yokuphepha komlilo yaseYurophu, kwenza i-Varicpand ibe uzakwazi othembekile wamaphrojekthi awo wonke amazinga, kusukela ekuthuthukisweni kwe-hydrant eyodwa kuya ohlelweni oluphelele lokucisha umlilo lwezimboni.

Ngaphezu komkhiqizo obonakalayo, i-Varicpand International iyehlukanisa ngokutholakala kwesitoko esithembekile kanye nokusekelwa kwezobuchwepheshe okuphendulayo, okuyizimfanelo ezibalulekile emkhakheni wokuvikela umlilo. Izinhlelo zokuvikela umlilo azikwazi ukubekezelela izikhathi ezinde zokulinda, futhi ukugcina isitoko esinamandla kosayizi bezixhumanisi abadumile kanye nezinto zokwakha kuqinisekisa ukuthi izidingo eziphuthumayo ziyahlangabezana ngokushesha, kungakhathaliseki ukuthi ukulungiswa okuvamile noma ukushintshwa okuphuthumayo. Ithimba lobunjiniyela benkampani lingaluleka ngokukhethwa kwezinto zokwakha zezixhumanisi, amazinga okucindezela, ukuhambisana kwezinto zokuvala, kanye nokuthobela imithethonqubo, lisize amakhasimende agweme amaphutha abizayo angabeka engozini ukuphepha. Izinsiza zangaphakathi ezinjenge-Landa ikhalenda kanye nehlelwe ImikhiqizoUkufakwa kohlu kusiza amaqembu okuthenga ukuthola ingxenye eqondile ayidingayo nokufinyelela emibhalweni eningiliziwe yobuchwepheshe. Lokhu kuhlanganiswa kobubanzi bomkhiqizo, ubuchwepheshe, nokugxila kumakhasimende yilokho okuhlukanisa i-Varicpand emakethe yokuncintisana yezinto zokucima umlilo zaseYurophu, futhi yisona sizathu esenza abakontraka abaningi nomasipala babuyele enkampanini ngezidingo zabo zokuxhuma.

I-Varicpand International inikeza uhla olubanzi lwemikhiqizo ehlanganisa yonke imindeni emithathu yama-coupling okuxoxwe ngayo kulesi sihloko, kanye nokukhethwa okuphelele kwezinsiza kanye nezingxenye eziyisipele eziqinisekisa ukuhambisana okuphelele kwesistimu. Ezinhlelweni zase-Guillemin, amakhasimende angakhetha kuma-aluminium, ibrasi, insimbi engagqwali, kanye nama-polypropylene variants, ngayinye yakhelwe ukuhlangabezana nezidingo zokucindezela nokugqwala koxhumo lwamanzi omlilo lwase-Europe. Uhla lwe-Storz luhlanganisa ama-coupling e-aluminium, ibrasi, nensimbi engagqwali kanye nezinsiza ezihambisanayo ezifana nama-cap, ama-plug, nama-gasket, konke kukhiqizwe ngokulinganisa okuqinile ukuze kube nokufakwa okuthembekile kwe-quarter-turn. Ezinhlelweni zezimboni, i-camlock portfolio ihlanganisa izinketho ze-aluminium, insimbi engagqwali, ibrasi, ne-polypropylene, kanye nama-dust cap, ama-gasket, nama-adaptor aqedela isistimu futhi avikele izindawo zokuvala. Umndeni ngamunye womkhiqizo usekelwa imibhalo yezobuchwepheshe enikelwe kanye nedatha yobukhulu esiza onjiniyela ukucacisa ingxenye efanele yokufakwa kwabo.

Amakhasimende angafinyelela kukhathalogi ephelele ngekhasi lokulanda kuwebhusayithi ye-Varicpand, lapho kutholakala khona imininingwane yezobuchwepheshe nemidwebo yobukhulu ukuze isetshenziswe njengereferensi yobunjiniyela, futhi lolu hlelo lwezinsiza luhlala lubuyekezwa ukuze lubonise intuthuko yakamuva yemikhiqizo. Inethiwekhi yokuthengisa ihlanganisa amazwe amaningi aseYurophu, futhi isitolo se-inthanethi sihlinzeka ngendlela elula yoku-oda izingxenye ezijwayelekile ku-inthanethi, okusheshisa kakhulu inqubo yokuthenga. Ngezidingo ezikhethekile, uhlelo lokubuza ngomkhiqizo luvumela amakhasimende ukuthi athumele imininingwane yawo futhi athole isilinganiso esenziwe ngokwezifiso eqenjini, okuqinisekisa ukuthi noma izicelo ezingajwayelekile ziyasekelwa ngokugcwele. Le ndlela ehlelekile yokutholakala komkhiqizo nokusebenza ngekhasimende iqinisekisa ukuthi osonkontileka bokuvikela umlilo nomasipala bangathola konke abakudingayo kumthengisi owodwa onokwethenjelwa, ngaphandle kobunzima bokuphatha abathengisi abaningi. Inhlanganisela yekhathalogi ephelele, ukusabalala kokuthengisa okubanzi, nokuphathwa kwemibuzo okusabelayo kwenza i-Varicpand ibe ukukhetha okungokwemvelo kwamaphrojekthi omlilo aseYurophu azo zonke izinhlobo nosayizi.

Ukuxhumeka kwamapayipi omlilo emadolobheni aseYurophu kuncike kakhulu ezingxenyeni ezijwayelekile zokuxhuma ezivumela izisebenzi zomlilo ukuthi zixhume amapayipi ngokushesha nangaphandle kokudideka, futhi ukukhethwa kohlobo lokuxhuma kwehluka ngamabomu kusukela ezweni ngezwe. EFrance, ama-Guillemin couplings afakwa kuma-hydrants, futhi abacimi bomlilo baphethe iziphethu zamapayipi ezihambisanayo ezikhiya ngesenzo esilula se-lever, okunikeza ukuxhumana okusheshayo nokuphephile. EJalimane naseScandinavia, ama-Storz couplings enza umsebenzi ofanayo, futhi indlela yawo yokukhiya ngokujika kwengxenye yesine yomjikelezo yaziwa wonke umuntu ngabasebenzi, okwenza ukusabela ngokushesha ngisho naphansi kwengcindezi enkulu. Ama-Camlock couplings avame ukutholakala kumapayipi amakhulu okuletha amanzi asetshenziselwa ukugcwalisa amathangi omlilo kusukela kuma-hydrants noma ukudlulisa amanzi phakathi kwamaphampu namadamu athuthukayo, lapho ukusebenza kwawo ngaphandle kwamathuluzi kuyinzuzo enkulu. Ngayinye yalezi zingxenye zokuxhuma zokuvikela umlilo kufanele yenziwe ngezinto ezingagqwali emanzini angaphansi komhlaba nasekuchayekeni izinto zemvelo kaningi, futhi insimbi engagqwali ivame ukucaciselwa ukufakwa okungapheli lapho impilo ende yesevisi ibalulekile.

Ukuxhumeka kwamaphampu emoto yomlilo kumelela enye indlela ebalulekile yokusetshenziswa, lapho ama-coupling kufanele amelane nomfutho ophezulu kanye nemijikelezo yokuxhuma evamile ngaphandle kokuvuza noma ukubhajwa, futhi ukukhethwa kwempahla kuthinta ngqo ukuthembeka. I-inlet nephampu yokuphuma emotweni yomlilo ivamise ukufakwa ama-Storz noma ama-camlock threads, okwenza kube lula ukuxhuma ngokushesha imigqa yokuhambisa nokukhipha engashintshwa ngokushesha ngesikhathi sesehlakalo. Izinhlelo zezimboni zokuvikela umlilo, njengalezo ezisezitshalweni zamakhemikhali, ezindaweni zokugcina izimpahla, nasezikhungweni zasolwandle, zivame ukusebenzisa ama-camlock couplings ngenxa yokuguquguquka kwawo nokulula kokunakekela ezindaweni ezisebenzayo ezinzima. Kulezi zimo, ama-stainless steel couplings avame ukucaciswa ukuze amelane namagwebu okucisha umlilo anamandla nama-chemical agents ngaphandle kokonakala, futhi ama-Viton seals ayasetshenziswa lapho ukuhambisana kwamakhemikhali kuyinkinga. Ukukhethwa okulungile kwempahla ye-coupling kusetshenziswa ngakunye kwalawa kuthinta ngqo ukulungela kokusebenza, ukuphepha kwabasebenzi, kanye nezindleko zesikhathi eside zokunakekela ingqalasizinda yokuvikela umlilo.

Ama-coupling akwa-Guillemin nawakwa-Storz womabili ayizinhlobo zokuxhuma ngokushesha ezilinganayo, kodwa asebenzisa izindlela ezahlukile zokukhiya futhi ahlobene namazinga ezwe ahlukene aseYurophu. Ama-coupling akwa-Guillemin asebenzisa iringi yokukhiya esebenza nge-lever ehlangana nama-lug acikilizanayo, futhi ayizinga elijwayelekile eFrance nasemazweni amaningi akhuluma isiFulentshi. Ama-coupling akwa-Storz asebenzisa ukunyakaza kwe-quarter-turn ngama-lug agobile futhi asungulwa eJalimane ngo-1882, aba izinga elijwayelekile emazweni akhuluma isiJalimane naseNordic. Womabili la ma-coupling atholakala nge-aluminium, nge-brass, nangensimbi engagqwali, futhi womabili avumela ukuxhuma okungaboni kahle kwezingxenye ezimbili ezifanayo. Ukukhetha phakathi kwawo cishe kuhlale kunqunywa izinga likazwelonke lomnyango wezomlilo osebenzisa le mishini.

Impahla yokuxhuma efanele yezinhlelo zomlilo namanzi incike kumfutho wokusebenza, indawo, kanye nesikhathi sokusebenza esilindelekile sengxenye. I-aluminium ekhohlisiwe iyona elula futhi elula kakhulu ukusebenza ngayo, okwenza ifaneleke kumapayipi aphathwa ngesandla kanye nemishini yezimo eziphuthumayo, futhi inikeza ukumelana nokugqwala okuhle kakhulu uma ifakwe i-anodised kahle. Insimbi engagqwali, ikakhulukazi i-AISI 316, inikeza izinga eliphezulu kakhulu lokumelana nokugqwala futhi iyanconywa ezindaweni zasolwandle kanye nasekuchayekeni kwamakhemikhali anamandla. I-Brass inikeza ukumelana nokugqwala okuhle kanye nokusebenza kahle, okwenza ifanelekele ukufakwa okungapheli kanye nezinhlelo zomfutho ophezulu lapho isisindo singakhathazi kangako. Kufanele njalo uqinisekise ukuthi uhambisana namazinga aseYurophu afana ne-EN 14420 lapho ukhetha.

Cha, izixhumanisi ze-Guillemin, Storz, ne-camlock azishintsheki phakathi kwazo ngoba zisebenzisa izinhlobo ezihluke ngokuphelele zokuxhuma kanye nezinqubo zokukhiya. Ingxenye ye-Guillemin ngeke ixhumeke kwingxenye ye-Storz, futhi ayikho kuzo ezoxhumeka ngqo kumfazi we-camlock. Nokho, kukhona ama-adaptor atholakalayo aguqulela phakathi kwalezi zindinganiso, okuvumela amaqembu ezicishamlilo ukuthi axhumanise imishini evela ezinhlelweni ezahlukene uma kunesidingo. Uma umsebenzi wakho uhilela izindinganiso eziningi zokuxhuma, kufanele ugcine isitokwe sama-adaptor afanele futhi uqinisekise amazinga awo okucindezela. I-Varicpand ingahlinzeka ngama-adaptor okuguqula ukuze ixhumanise le mehluko yezindinganiso ngokuphephile.

Izinga lokucindezela elijwayelekile lama-coupling okuvikela umlilo liyahlukahluka ngosayizi, impahla, nomkhiqizi, kodwa ama-coupling amaningi asezingeni eliphezulu alinganiswa ukuthi asebenze ngaphansi kwengcindezi yokusebenza okungenani amabhawa ayi-10 kuya kwangu-16, okudlula kalula amazinga okucindezela ajwayelekile wamaphampu omlilo. Ama-coupling e-aluminium nensimbi engagqwali ngokuvamile anikeza amazinga okucindezela aphezulu kunalezo ezenziwe nge-polypropylene, futhi imizimba ekhanyisiwe iqine kunalezo ezakhiwe ngokucindezelwa. Izinga lokucindezela livamise ukubhalwa emzimbeni noma lichazwe emibhalweni yezobuchwepheshe yomkhiqizi. Uma ucacisa ama-coupling, hlala uqinisekisa ukuthi izinga lokucindezela elilinganisiwe lidlula ingcindezi ephezulu kakhulu engakhiqizwa iphampu yakho yomlilo, kuhlanganise nengcindezi yokugijima. Ezinhlelweni ezikhethekile zokucindezela okuphezulu, ama-coupling ensimbi engagqwali anedizayini eqinisiwe ayikhetho eliphephile kakhulu.

I-NBR (nitrile) iyinto evame kakhulu futhi engabizi kakhulu yokuvala amanzi emlilweni ajwayelekile, inokumelana kahle namanzi kanye namagwebu okucisha umlilo ajwayelekile. I-EPDM iyanconywa ezimweni lapho amanzi engaphathwa ngamakhemikhali athile noma lapho kudingeka khona ukumelana nokushisa okukhulu, futhi ibamba kahle kakhulu i-ozone kanye nesimo sezulu. I-Viton (FKM) iyona nkinga engcono kakhulu ezindaweni ezinamakhemikhali anamandla kanye nokuchayeka ekushiseni okuphezulu, nakuba ibiza kakhulu kunezinye izinketho. Ama-elastomer ezinga lokudla ayatholakala ezimweni lapho kufanele kugcinwe khona ukuhlanzeka kwamanzi, njengezikhungo zokucubungula ukudla. Into yokuvala kumele ngaso sonke isikhathi ihambisane nezithako ezithile zokucisha umlilo ezisetshenziswa ohlelweni lwakho ukuze kugwenywe ukuvuvukala noma ukucekelwa phansi.

Yebo, i-Varicpand International isekela usayizi owenziwe ngokwezifiso, ukuthungwa, kanye nokuhlelwa kwe-flange kuzo zonke izinhlobo zayo zokuxhuma, okuvumela ukuxhumana kwamanzi omlilo okungajwayelekile ukuba kwakhiwe ngokwezidingo eziqondile. Amandla enkampani okukhiqiza angakwazi ukwamukela izinhlobo zokuthungwa ezingejwayelekile, ububanzi obungavamile, kanye nezidingo ezikhethekile zokucindezela. Izixhumi ezenziwe ngokwezifiso zivivinywa ngokugcwele futhi zibhalwe phansi ukuze kuqinisekiswe ukuthi zihlangabezana namazinga adingekayo aseYurophu. Amakhasimende angathumela izidingo zawo ngohlelo lokubuza ngomkhiqizo kuwebhusayithi futhi athole isilinganiso esenziwe ngokwezifiso. Lokhu kuvumelana nezimo kubaluleke kakhulu ekulungiseni izinhlelo ezindala noma ekufakweni kwezimboni okukhethekile lapho izingxenye ezijwayelekile zingafaneleki khona.

Yebo, iVaricpand International ikhiqiza ama-couplings ayo ukuze ahambisane nezindinganiso ezinkulu zaseYurophu ezilawula imishini yokuvikela umlilo, okuhlanganisa i-EN 14420 yezinsimbi zamahose kanye ne-ISO 14565 yama-couplings amahose omlilo. Inkampani futhi iqinisekisa ukuthi izinto zokusebenza nezinqubo zokukhiqiza zihlangabezana nezidingo ezisebenzayo zekhwalithi nokuphepha zemishini yezinsizakalo zomlilo. Imibhalo nezitifiketi zokuvumelana ziyatholakala kumakhasimende adinga ukuqinisekiswa kokuthobela imithetho yamaphrojekthi abo. Uma ucacisa ama-couplings ohlelo lokuvikela umlilo, kubalulekile ukucela nokubuyekeza le mibhalo yokuthobela imithetho. Ukuzibophezela kweVaricpand ekuthobeleni imithetho kunikeza onjiniyela namathimba okuthenga ukuzethemba ezinqumweni zabo zokuthenga.

Uhlobo olungcono kakhulu lokuxhuma kwamaphampu ezimoto zomlilo luncike ezindinganisweni zikazwelonke zomnyango wezomlilo kanye nendima ethile yokuxhuma emotweni. Ama-Storz couplings ayikhetho elivame kakhulu ekuxhumaneni kokungena nokuphuma kwephampu eJalimane, e-Austria, eSwitzerland, naseNyakatho Yurophu, ngenxa yomklamo wawo oqinile wokujika kwesine kanye nezidingo eziphansi zokunakekela. Ama-Camlock couplings asetshenziswa kakhulu ekungeneni kwephampu lapho amapayipi amakhulu okudonsa kufanele axhunywe futhi axhunywe ngokushesha, futhi ukusebenza kwawo ngaphandle kwamathuluzi kuyinzuzo enkulu. Ama-Guillemin couplings ayizinga lokuxhuma kwamaphampu eFrance nakwezinye izimakethe ezilandela umkhuba waseFrance. Noma yiluphi uhlobo, impahla kufanele ikhethwe ukuze imelane nokucindezela nezimo ezibangela ukugqwala ezilindelekile ekusebenzeni komnyango wezomlilo, kanti i-aluminium ebunjiwe nensimbi engagqwali yizona ezikhethwa kakhulu.

Ububanzi bezinga lokushisa lokusebenza kwe-coupling lunqunywa ikakhulukazi izinto zokuvala kanye nezinto zomzimba, hhayi ukwakheka kwe-coupling ngokwayo. Imizimba ye-aluminium, ithusi, kanye nensimbi engagqwali ngokuvamile ingasebenza ebangeni elibanzi kakhulu lokushisa, kusukela emazingeni okushisa aphansi ebusika kuya ngaphezu kuka-100 degrees Celsius. Ama-seal e-NBR ngokuvamile alinganiswa ukusuka cishe ku--20°C kuya ku-+100°C, kuyilapho i-EPDM inikeza ububanzi obufanayo nokumelana okungcono nesimo sezulu. Ama-seal e-Viton anweba umkhawulo wokushisa ophezulu ukuya cishe ku-200°C, okubalulekile ezinhlelweni eziseduze nemithombo yokushisa. Kumaphrojekthi omlilo waseYurophu, kufanele uqinisekise ukuthi izinto zokuvala zifanele amazinga okushisa aphansi kakhulu asebusika endawo yakho, ngoba ama-elastomer amaningi ajwayelekile aba buthaka emazingeni okushisa aphansi kakhulu.
