Uma kumayelana nokuklama izinhlelo zokucima umlilo ezithembekile kulo lonke elaseYurophu, kumbalwa izinto ezibaluleke kakhulu kune-coupling elula ehlanganisa amahose, amaphampu, ama-hydrant, namathangi okugcina ndawonye. Lezi zinsimbi zokuxhuma zinomsebenzi wokuqinisekisa ukuvala okungavuzi amanzi ngaphansi kwengcindezi enkulu yamanzi, futhi ukusebenza kwazo kungasho umehluko phakathi kokucima umlilo okulawulekayo nokwehluleka okuyinhlekelele endaweni yomlilo. Lo mhlahlandlela obanzi uqhathanisa izinhlobo ezintathu ze-coupling ezisetshenziswa kakhulu kumaphrojekthi omlilo aseYurophu: i-Guillemin, i-Storz, ne-Camlock, ngokugcizelela okukhethekile ekukhetheni izinto zokwakha. Ngalinye lalawa mndeni wama-coupling linikeza izinzuzo ezihlukile mayelana nesivinini sokuxhuma, ukuqina kokuvala, ukuphatha ingcindezi, nokuhambisana nemishini ekhona yomlilo yaseYurophu, ngakho ukukhetha kudinga ukuhlaziywa ngokucophelela kwezidingo zokusebenza zephrojekthi. Sizobuye sihlole izindlela ezibalulekile zokukhetha izinto zokwakha okumele onjiniyela, ochwepheshe bokuthenga, nabaphathi bomlilo bakuhlole ngaphambi kokuzibophezela kumkhiqizo othile, okuhlanganisa ukumelana nokugqwala, amazinga engcindezi, ukubekezelela izinga lokushisa, isisindo, nokuqina. Ukwengeza, sizogqamisa indlela i-Varicpand International esekela ngayo ochwepheshe bokuvikela umlilo kulo lonke elaseYurophu ngezixazululo ze-coupling eziqinisekisiwe, ezisezingeni eliphezulu ezihlangabezana nezidingo eziqinile zokulawula. Ekupheleni kwalesi sihloko, uzobe unalo lonke ulwazi lobuchwepheshe oludingekayo ukuze wenze isinqumo esinengqondo mayelana nokuthi yiluphi uhlobo lwe-coupling nezinto zokwakha ezifaneleka kakhulu iphrojekthi yakho yomlilo yaseYurophu.

Izinhlelo zokucima umlilo eYurophu zisebenza ngaphansi kwezimo ezinzima neziguquguquka kakhulu, kusukela kumanethiwekhi e-hydrant asemadolobheni asiza amadolobha anabantu abaningi kuya ekufakweni kwezinto zokucisha umlilo ezisezimbonini ezitholakala ezitshalweni zamakhemikhali, ezindaweni zokuhlanza uwoyela, nasezikhungweni zokukhiqiza ugesi. I-coupling ekhethelwe lezi zinhlelo kumele imelane nokucindezela okuphezulu kwamanzi, imelane nokugqwala okubangelwa umswakama, ukuchayeka kumakhemikhali, nomoya osawoti ogwini, futhi inikeze ukuvala okuthembekile, okungavuziyo ngaphansi kwengcindezi enkulu yemishini, okuhlanganisa ukudlidliza, ukushaqeka, nokushintshashintsha kwezinga lokushisa. Ngaphezu kwalokho, imiyalelo yaseYurophu nemithetho kazwelonke ibeka amazinga aqinile emishinini yokucisha umlilo, okwenza ukuthobela amazinga afana ne-EN 14420-6, EN 14420-7, EN 14420-8, ne-NFE 29572 kube yinto ephoqelekile yokuthenga kunoma yimuphi umsebenzi womphakathi noma wangasese. Imindeni emithathu yama-couplings okuxoxwe ngayo kulo mhlahlandlela imele izindlela ezahlukene zokuklama, futhi ngayinye izitholele indawo ehlukile emakethe yokuvikela umlilo yaseYurophu, ngakho ukuqonda lokhu kwehluka kubalulekile lapho ucacisa izingxenye zephrojekthi yakho. Ama-Storz couplings abusa ekuxhumaneni okujwayelekile kwamapayipi omlilo nasezindaweni zokuphuma kwamanzi ezindaweni eziningi zaseYurophu, kuyilapho ama-Guillemin couplings esetshenziswa kakhulu ezinkonzweni zomlilo zaseFrance nasezinhlelweni zokulayisha amathangi ezimbonini, futhi ama-Camlock couplings anikeza ukusebenza okusheshayo kokuxhuma ezindimeni zokusekela. Ngolwazi oluningi lweminyaka eminingi lwezimboni kanye nohlu olubanzi lwemikhiqizo, i-Varicpand International isize izinhlangano eziningi ukuthi zithole izinqumo ezicacile mayelana nokucaciswa futhi zithole ama-couplings anikeza ukusebenza kahle, inani, nokuphila isikhathi eside ezindaweni zazo ezisebenzayo.

Izihlanganisi ze-Storz zibonakala ngokushesha ngomklamo wazo olinganayo, osekelwe kuma-lug, onazo izingxenye ezimbili ezihlangene ezinama-lug afanayo, izivalo zangaphakathi, futhi akukho umehluko phakathi kowesilisa nowesifazane phakathi kweziphetho ezimbili ezixhumeneyo. Lokhu kulingana okungokwemvelo kusho ukuthi noma iziphi izihlanganisi ezimbili ze-Storz zobukhulu obufanayo obujwayelekile zingaxhunywa ndawonye ngokushesha nangokuqiniseka ngaphandle kwesidingo sokufuna ucezu olufanayo lokuxhuma, okwenza kube lula kakhulu ukuphathwa kwempahla eziteshini zabomlilo, ezimotweni zomlilo, nasezindaweni zokugcina impahla. Ukuxhumana kufinyelelwa ngomnyakazo olula wokukhiya ngekota yokujika ocindezela ubuso bezihlanganisi ezimbili ndawonye futhi ucindezele i-gasket yangaphakathi, kudala ukuvala okungangeni manzi okusheshayo ukuxhuma futhi okusheshayo ukukhulula. Kulo lonke izwekazi laseYurophu, izihlanganisi ze-Storz zisebenza njengezinga elijwayelekile lokuxhuma amapayipi omlilo, izindawo zokuphuma kwamanzi, imigqa yokudonsa amanzi, nokuxhunywa kokukhipha amanzi, futhi zicaciswe ezindinganisweni zikazwelonke kusukela ku-DIN 14301 yaseJalimane kuya ku-ÖNORM F 3140 yase-Austria kanye nemihlahlandlela ye-VKF yaseSwitzerland. Ukwamukelwa kwazo okubanzi kusho ukuthi imishini ekhiqizwa yizinkampani ezahlukene isebenza ngokuhambisana ngaphandle kwezinkinga zokuhambelana, okucatshangwa okubalulekile emabuthweni omlilo aphendula ngaphesheya kwemingcele yomasipala noma yezwe. Uhlu lomkhiqizo we-Storz Couplings e-Varicpand International luhlanganisa izinguqulo ze-aluminium, zethusi, nezensimbi engagqwali ukuze kuhlangatshezwane nezimo ezahlukene zemvelo, izigaba zokucindezela, nokulindeleka kwempilo yokusebenza.

Ama-Guillemin couplings, aziwa nangokuthi ama-symmetric couplings noma "système Guillemin," anamhlathi amane axhumene ahlelwe ngokulinganayo azungeze umzimba we-coupling, enikeza ukuxhumana okomele nokuvikelekile ngomshini okuphikisa ngempumelelo ukunqanyulwa okungahlosile ngesikhathi sokusebenza okunomfutho ophezulu noma ukudlidliza okukhulu. Idizayini isebenzisa indlela yokuxhuma efana ne-bayonet lapho izingxenye ezimbili ze-coupling zicindezelwa ndawonye zisontwe, kube ne-gasket eyindilinga ebekwe phakathi kobuso ukuze kutholakale ukuvala okuthembekile, okungavuzi. Lawa ma-couplings avame kakhulu ezinhlelweni zomlilo zaseFrance naseBelgium, futhi ayindlela ejwayelekile yokusebenza kokulayisha nokukhipha amathangi ezimbonini, lapho ukuxhumana okuphephile nokungavuzi kuyimpoqo kukho kokubili ukuphepha nokuthobela imithethonqubo. Ukuhlelwa kwemihlathi emine kusabalalisa imithwalo yemishini ngokulinganayo ezungeze umjikelezo we-coupling, okunciphisa ukugxila kwengcindezi, kuvimbele ukuwohloka kwendawo ethile, futhi kuthuthukise ikhono le-coupling lokumelana namazinga omfutho aphezulu kakhulu esikhathini eside sokusebenza. Ama-Guillemin couplings akhiqizwa nge-brass, i-aluminium, insimbi engagqwali, ne-polypropylene, okuvumela onjiniyela bamaphrojekthi omlilo ukuthi bafanise impahla ngqo noketshezi olusingathwayo, indawo ezungezile, kanye nemvamisa elindelekile yemijikelezo yokuxhuma. I-Varicpand International inikeza uhlu olubanzi lwama-Guillemin Couplings, okuhlanganisa amamodeli e-aluminium alula ezimoto zokucisha umlilo ezihambayo kanye nezinketho zensimbi engagqwali ezinzima zokufakwa unomphela kwezimboni zokuvikela umlilo ezidinga ukumelana nokugqwala nokuqina okuphezulu kakhulu.

Camlock couplings, okuvame ukubizwa ngokuthi ama-cam-and-groove couplings, asebenzisa indlela ye-lever-arm enika amandla ukuxhuma nokuhlukanisa ngokushesha, ngaphandle kwamathuluzi, amahose, amapayipi, nezinsimbi zokuxhuma ngemizuzwana nje. Uhlelo lwakhiwe nge-female adaptor efakwe izingalo ze-cam ezixhunywe nge-spring kanye ne-male adaptor enomsele owenziwe ngobuchule, futhi uma ama-lever evaliwe, ama-cam akhinya ngokuqinile emseleni ukuze akhe ukuxhumana okuqinile nokuphephile ngokomshini. Lo mklamo uye wamukelwa emhlabeni wonke ngaphansi kwezimfuneko ezifana ne-MIL-C-27487 ne-DIN 2828, okusho ukuthi ama-Camlock couplings akhiqizwa noma yimuphi umkhiqizi othembekile ayalingana ngobukhulu, okunikeza ukuguquguquka okukhulu ekuthengeni kwemiklamo enabahlinzeki abaningi. Nakuba ngokwesiko engasetshenziswa njengokuxhumana okuyinhloko kumahose omlilo, ama-Camlock couplings asetshenziswa kakhulu ezinhlelweni zokusekela ukucisha umlilo, okuhlanganisa imigqa yokuhlinzeka ngamanzi yesikhashana, imigqa yokudlulisa i-foam concentrate, izixhumanisi zokuhlola izifutho ze-sprinkler, nezinye izifunda eziyizinsiza ezidinga ukumiswa nokuhlukaniswa ngokushesha. Ikhono lazo lokuxhuma ngokushesha libenza zilungele izimo zokusabela eziphuthumayo lapho isivinini sokumisa sibalulekile, kodwa zihlala zilula futhi zincane, okwenza kube lula ukuzigcina nokuzithutha. I-Varicpand International ihlinzeka ngama-Camlock Couplings ngezinto eziningi ezahlukene, okuhlanganisa i-aluminium, ithusi, insimbi engagqwali, i-polypropylene, ne-nylon, ngayinye yalezi zinhlobo yakhelwe izimo ezithile zokusetshenziswa, izidingo zokuhambisana namakhemikhali, nezidingo zokucindezela.

Ukumelana nokugqwala kungumkhakha obaluleke kakhulu ekukhetheni izinto zokwakha zamacouplings asetshenziswa kumaphrojekthi omilio waseYurophu, ngoba lezi zingxenye zivame ukuchayeka kumswakama, umswakama, amahhwa amakhemikhali, futhi ezindaweni ezisogwini, emoyeni onosawoti okhulisa kakhulu ukucekelwa kwensimbi. Ama-aluminium couplings anokumelana nokugqwala okuhle ezinhlelweni zamanzi ahlanzekile futhi afaneleka kahle ukufakwa ngaphakathi, kodwa asengozini yokugqwala kwe-galvanic uma ehlanganiswa nezinsimbi ezihlukile njengethusi noma insimbi endaweni emanzi noma enomswakama, okungaholela ekugqwaleni, ukuvaleka kwemicu, nokwehluleka ngaphambi kwesikhathi. Ama-brass couplings ahlinzeka ukumelana nokugqwala okuphezulu emanzini anosawoti futhi avame ukukhethwa eziteshini zomilio zasogwini, izikhungo zamachweba, nezinhlelo zokucisha umlilo zasolwandle, nakuba isisindo sazo esiphezulu kakhulu kufanele sicutshungulwe ekwakhiweni kwemishini nasekusetshenzisweni kwayo. Ama-stainless steel couplings, ikakhulukazi lawo enziwe nge-304 noma i-316L, ahlinzeka izinga eliphezulu kakhulu lokuvikelwa ekugqwaleni phakathi kwazo zonke izinto ezivamile futhi acishe angathinteki ekucekelweni umswakama, amakhemikhali, nokuchayeka elangeni, okwenza abe ukukhetha okufaneleke kakhulu ezindaweni ezinzima zezimboni nasekufakweni kwangaphandle kwesikhathi eside. Lapho kuhlolwa ukumelana nokugqwala, kubalulekile ukucabangela hhayi kuphela uketshezi oluyinhloko oluthuthwayo kodwa nezimo zomoya ezizungezile, imvamisa yokuhlanza noma ukuchayeka kumakhemikhali, kanye nesikhathi sokusebenza esilindelekile sohlelo lomilio, okuthi emaphrojekthini amaningi aseYurophu ludlule iminyaka engamashumi amabili nanhlanu. Imishini yomilio ivame ukugcinwa ngaphandle, ifakwe kuma-trailers, noma igcinwe ezindlini zokumpompa ezinomswakama, ngakho into ekhethiwe kufanele imelane neminyaka yokuchayeka emvelweni ngaphandle kokulahlekelwa ukuqina kwesakhiwo noma ukunemba kobukhulu, okungaphazamisa umsebenzi wokuvala. I-Varicpand International inolwazi olubanzi ekuqondiseni amakhasimende ekukhetheni izinto ezindaweni ezinokugqwala futhi ingahlinzeka amashadi okuhambisana kwe-galvanic, idatha yokuhlolwa kokugqwala, nezitifiketi zezinto zokwakha ukusekela izinqumo zakho zobunjiniyela.

Yonke i-coupling inesilinganiso esiphezulu sokucindezela kokusebenza, okumelela umfutho omkhulu wamanzi wangaphakathi umshini ongawuthwala ngokuphephile ngesikhathi sokusebenza okuqhubekayo, futhi ukukhetha into enesilinganiso esanele sokuphepha ngaphezu kwezinga lokucindezela lokusebenza kwesistimu yakho kuyimfuneko eyisisekelo yokuphepha okungamelwe izekelwe. Ama-brass couplings ngokuvamile anikeza amazinga aphezulu kakhulu okucindezela phakathi kwezinto ezijwayelekile ze-coupling, futhi amamodeli amaningi alinganiselwe ukucindezela kokusebenza ngaphezu kwe-40 bar, kuyilapho ama-aluminium couplings ngokuvamile esekela amazinga acishe abe ngu-25 bar, okwenza afaneleke ngokuphelele ekusetshenzisweni kokucisha umlilo komasipala lapho ukucindezela kwe-10 kuya ku-16 bar kuyizinga elijwayelekile. Ama-stainless steel couplings nawo afinyelela amazinga amahle kakhulu okucindezela, ngokuvamile edlula i-40 bar, kuyilapho ngasikhathi sinye enikeza ukubekezelela amazinga okushisa aphezulu, okwenza akwazi ukuphatha konke kusukela kuma-cryogenic fluids ku-minus 40 degrees Celsius kuya ezinqubweni zezimboni ezishisayo ezingabangela ama-elastomeric seals nezinsimbi ezibuthakathaka ukuthi ziguquke noma zehluleke. Ama-plastic couplings, njengalawo enziwe nge-polypropylene noma i-nylon, ngokuvamile alinganiselwe emazingeni aphansi okucindezela we-6 kuya ku-10 bar, kodwa anikeza ukuhambisana okuhle kakhulu namakhemikhali kanye nesisindo esilula kakhulu, okwenza akhangayo ezinhlelweni ezikhethekile lapho kukhona amakhemikhali anamandla futhi ukucindezela okuphezulu kungadingekile. Amaphrojekthi omilio waseYurophu kumele futhi acabangele ububanzi obugcwele bezinga lokushisa lamanzi, ekhumbula ukuthi amanethiwekhi kamasipala enyakatho ye-Scandinavia angahlangabezana namazinga okushisa aseduze nokubanda, kuyilapho izinhlelo zomilio zezimboni eNingizimu Yurophu zingachayeka ekushiseni okungaphezu kuka-50 degrees Celsius. Into ekhethiwe kumele igcine ukuqina kwayo kwemishini kulo lonke lolu hlu lokushisa ngaphandle kokuba buthaka emazingeni okushisa aphansi, ukulahlekelwa ubulukhuni emazingeni okushisa aphezulu, noma ukwanda okuhlukile kokushisa okungabeka engcupheni ukusebenza kokusebenza kwe-coupling noma ukulingana kwayo. Emisebenzini yokucisha umlilo, i-coupling ehluleka ngenxa yokucindezeleka kokushisa akulona nje inkinga, kodwa kuyingozi enkulu yokuphepha engabeka abacishi bomlilo engcupheni yemifutho yamanzi enomfutho ophezulu noma ishiye isistimu yokucisha umlilo ingasebenzi ngesikhathi esidingeka kakhulu.

Ezimweni zokucima umlilo, ikhilogremu ngalinye lemishini okufanele ithwalwe, iphakanyiswe, futhi ixhunywe libaluleke kakhulu, ikakhulukazi ngesikhathi sokusebenza okunwetshiwe lapho abacimi bomlilo sebekhathele, futhi isisindo sokuxhunywa singathinta kakhulu ukusebenza kahle kokuphatha amapayipi, ukugcinwa emalolini, nokuhlelwa kwemishini. Izixhunywa ze-aluminium zingumholi obonakalayo ekwehliseni isisindo, zinikeza ukonga okucishe kube ngu-60% uma kuqhathaniswa nezixhunywa zethusi ezilinganayo zosayizi ofanayo, okuhumushela ekunciphiseni ukucindezeleka komzimba kubasebenzi bomlilo, ukushesha kokuthunyelwa kwemishini, nokwandisa amandla okusebenza ngesikhathi sezigameko ezinkulu. Nokho, ukonga isisindo kufanele kulinganiswe ngokucophelela nokuqina, ngoba i-aluminium iyinto ethambile, eguquguqukayo evame ukugoba, ukuklwebheka, ukugqwala, nokonakala kobuhle ngesikhathi ukuphathwa ngobudlwangudlwangu, ukuvivinywa okuphindaphindiwe kokuwa, nokuthintana nokugqwayiza nokhonkolo, amatshe, noma amashalofu ezimoto. Izixhunywa zethusi, nakuba zisinda kakhulu, zimelana nokonakala kwemishini, ukuguquka kwesimo, nokugqoka kangcono kakhulu kune-aluminium, zinikeza impilo yokusebenza ende ezimweni ezinzima zendawo yomlilo futhi zibekezelela ukuphathwa kanzima okuvamile ezimweni zokusabela eziphuthumayo. Insimbi engagqwali inikeza inhlanganisela enhle kakhulu yamandla emishini aphezulu nokumelana nokugqwala okuhle kakhulu, kodwa ukuminyana kwayo kuyibeka phakathi kwe-aluminium nethusi ngezinga lesisindo, okwenza kube ukukhetha okuthandwayo ezifakweni ezihlala njalo lapho isisindo singeyona inkinga enkulu. Ukuthobela izindinganiso zaseYurophu ezifana ne-EN 14420-6 yezixhunywa ze-Storz, i-EN 14420-7 yezixhunywa zohlobo lwe-Guillemin, ne-EN 14420-8 yezixhunywa zohlobo lwe-Camlock kuyimpoqo ngokuphelele emishinini yomlilo ethengiswayo futhi esetshenziswa e-European Union, futhi lezi zindinganiso zibeka imithetho eqinile ngezinto zokwakha, ubukhulu, amazinga okucindezela, nezinqubo zokuhlola. Izinqubo zokukhiqiza ze-Varicpand International zakhelwe ukuthobela lezi zindinganiso eziqinile zaseYurophu kusukela ekuqaleni kokutholwa kwezinto zokwakha kuze kube sekuhlolweni kokugcina kwekhwalithi, futhi inkampani inikeza izitifiketi nemibhalo eqinisekisa ukuthobela okugcwele kuzo zonke izindinganiso ezisebenzayo.

Uma zonke izikhathi zibalulekile ngesikhathi sezimo eziphuthumayo, isivinini okuxhunywa ngaso amapayipi, ukusungulwa kokugeleza kwamanzi, nokufakwa kwezinhlelo ukuthi zisebenze kuba yinto ebalulekile ekusebenzeni okuqondile okuthinta imiphumela yokucisha umlilo nokuphepha kwabaphenduli. Ama-Storz couplings adume ngokufanele ngokusebenza kalula okumangalisayo, ngoba idizayini yawo elinganiselayo ivumela abacishi bomlilo ukuthi baxhume amapayipi amabili ngesikhathi esingangemizuzwana emibili kuya kwemithathu, ngaphandle kokudinga ukuhlola ukuthi imiphetho ingowesilisa noma owesifazane, ngokumane nje uqondanise izingxenye ezimbili bese ufaka ukuvala okuqinile kwekota yokujika. Ama-Guillemin couplings adinga isenzo esifanayo sokujika ukuze axhumeke, kodwa adinga ukuqondaniswa ngokucophelela kwemihlathi emine ehlanganayo, okungangeza imizuzwana emibili kuya kwemihlanu esikhathini sokuxhumeka, umehluko oba nokubaluleka ngesikhathi sokuhlasela kwangaphakathi okuhamba ngokushesha noma lapho kusebenza ezimweni zomsi ongabonakali. Ama-Camlock couplings anikeza isikhathi esisheshayo sokuxhumeka kuzo zontathu izinhlelo, ngoba izingalo zamalever zingavalwa ngomnyakazo owodwa opholile ngesandla esisodwa, okunikeza ukuqinisekiswa okusheshayo kokubona nokuthinta kokubambana, yingakho edumile kakhulu ekusungulweni kwezinhlelo zamanzi zesikhashana neziphuthumayo. Mayelana nokusebenza kokuvala, ama-Storz couplings ahamba phambili ngoba i-gasket yangaphakathi icindezelwa ngokulinganayo nxazonke ngesenzo se-lug, kukhiqize ukuxhumeka okuthembekile, okungaconsi ngezingcindezi ezifinyelela nangale kuka-30 bar, okwenza kube yindinganiso eyisiqinisekiso ezinhlelweni ezibalulekile zamapayipi omlilo. Ama-Guillemin couplings anikeza ukusebenza kokuvala okumangalisayo ngokufanayo ngenxa yendawo enkulu yokuthintana kwe-gasket nokucindezelwa okulinganayo okuzuzwa umshini wokuvala wemihlathi emine, kodwa adinga ukuqondaniswa okunembile kwemihlathi, futhi ukuxhumeka okungahambisani kahle kungaholela ekulayisheni kwe-gasket endaweni ethile okubeka engcupheni ukuqina kokuvimbela ukugcwele ngezingcindezi eziphezulu kakhulu. Ama-Camlock couplings, nakuba esebenza kahle ezinhlelweni zokucindezela okuphansi kuya kokumaphakathi kuze kufike ku-10 bar, ngokwemvelo asengozini enkulu yokuvuza uma izingalo ze-cam zingavalwa ngokugcwele noma uma i-gasket ye-elastomeric iye yacindezelwa noma yangcoliswa ngokuhamba kwesikhathi, ngakho akunconywa ukuthi abe ukuxhumeka okuyinhloko emigqeni yokucisha umlilo enengcindezi ephezulu.

Ikhono lokumelana nokucindezela okuphezulu kwamanzi ngaphandle kokwehluleka, ukuvuza, noma ukwehlukana kokuxhuma kuyimfuneko yokuphepha engenakuphikiswa emishinini yokucisha umlilo, futhi umehluko wezinga lokucindezela phakathi kwemiklamo yokuxhuma uyisici esikhulu enqubweni yokukhetha. Izixhumi ze-Storz zakhelwe ukumelana nokucindezela okuphezulu kakhulu, nezinhlobo ezisindayo ezilinganiselwe ukuphatha ukucindezela kokusebenza okungaphezu kuka-40 bar, okwenza zifanelekele zombili izinhlangothi zokudonsa nokukhipha amanzi kumaphampu omilio, lapho ukucindezela okuguquguqukayo kungavela khona ngenxa yokushayiswa kwamanzi nokuvalwa kwamasongo ngokushesha. Izixhumi ze-Guillemin nazo ziqine kakhulu, futhi ukwakheka kwazo kwemihlathi emine kunikeza amandla amakhulu okwakheka, nezinga lokucindezela elivamise ukusuka ku-16 kuya ku-40 bar kuye ngokuthi izinto ezisetshenzisiwe, usayizi, nokukhethwa kwegasket, okwenza zanele ezinhlelweni eziningi zokucisha umlilo nezokuvikela umlilo ezimbonini. Izixhumi ze-Camlock ngokuvamile zisebenza ngamazinga okucindezela aphansi kunezixhumi ze-Storz ne-Guillemin, ngokucindezela okujwayelekile kokusebenza okuyi-6 kuya ku-16 bar ezinhlotsheni ze-aluminium kanye namazinga aphezulu kancane kwezethusi nensimbi engagqwali, okukhawulela ukusetshenziswa kwazo ezimweni eziqondile zokucisha umlilo lapho ukucindezela okuphezulu kubalulekile. Ukuhambisana nengqalasizinda ekhona yezinsiza zomlilo zaseYurophu mhlawumbe kuyisici esibaluleke kakhulu esinqumweni, futhi lapha i-Storz inesikhundla esiqinile esingenakuphikiswa ngoba ihlanganiswe ezindaweni zokukhipha amanzi ezijwayelekile zomlilo, izixhumi zamahose, nokuxhunywa kwemishini emazweni amaningi e-European Union. Izixhumi ze-Guillemin ziyindlela ejwayelekile yezinsiza zomlilo zaseFrance kanye nemisebenzi yamathangi ezimbonini esamukele izinga le-NFE 29572, futhi nazo zisetshenziswa kabanzi eBelgium naseLuxembourg, okwenza zibe ukukhetha okunengqondo kumaphrojekthi akulezo zifunda. Izixhumi ze-Camlock zilawulwa amazinga aziwa ngamazwe ngamazwe futhi zitholakala ngosayizi abaningi kusukela ku-12.5 mm kuya ku-150 mm, kodwa ukusetshenziswa kwazo emisebenzini yomlilo kamasipala kukhawulelwe ezinhlelweni zokusiza, imigqa yesikhashana, namanethiwekhi okukhiqiza umlilo ezimbonini lapho ukuhlukaniswa ngokushesha kubaluleke kakhulu kunekhono lokucindezela okuphezulu.

Izinto zokuphendula umlilo kulindeleke ukuthi zihlale zikulungele ukusebenza amashumi eminyaka, ngakho izici zokugcinwa kwempahla zesikhathi eside zezinto zokuxhuma zithinta ngokuqondile izindleko zokunikela, izidingo zabasebenzi, nokwethembeka kokusebenza. Izixhumi zethusi zidinga ukugcinwa okuncane kakhulu ngaphandle kokuhlolwa ngezikhathi ezithile, ukuhlanza, nokushintshwa kwama-gasket, ngoba ukushelela kwemvelo kathusi kugcina izingxenye ezinemicu nezokukhiya zihamba kahle ngisho nangemva kwezikhathi ezinde zokungasebenzi, kuvimbela ukunamathela nokugqwala. Izixhumi ze-aluminium zidinga ukugcinwa ngokucophelela okwengeziwe, ngoba into yazo ijwayele ukugqwala ebusweni nokugqwala kwe-galvanic uma ihlanganiswa nezinsimbi ezihlukile, futhi izindlela zokukhiya kufanele zigcotshwe ngezikhathi ezithile ngamafutha afanele ukuze kuqinisekiswe ukusebenza kahle eminyakeni eminingi yokusebenza. Izixhumi zensimbi engagqwali zidinga ukugcinwa okuncane kakhulu kuzo zonke izinto, zigcina ubuqotho bazo bokwakheka, ukunemba kobukhulu, nokubukeka okucwebezelile ngisho nangemva kwamashumi eminyaka kuchayeka esimweni sezulu esibi, umoya wasolwandle, amakhemikhali, nentuthu yezimboni, nakuba izindleko zokuqala zibonisa lokhu kuqina okuphezulu.
