Emhlabeni wokudluliswa kwezinto ezingamanzi ezimbonini, ukwethembeka kokuxhumana kuvame ukunquma ukuphepha nokusebenza kahle komsebenzi wonke. Izixhumi ezisheshayo yizona eziqhawe ezifihliwe emikhakheni esukela ekucimeni umlilo nasekuqhubeni amakhemikhali kuya ekwelapheni amanzi nasekuqhubeni uwoyela negesi. Ukukhetha uhlobo olungalungile kungaholela ekophuneni, ekuyekeni ukusebenza, nasezingozini ezibizayo zokusebenza. Kubaphathi bezokuthenga kanye nonjiniyela bokugcinwa ezindaweni eziningi eYurophu nangaphezulu, ukuqonda umehluko phakathi kwezixhumi ze-UNI, GOST, ne-Storz akuyona nje into yokufunda kodwa kuyisinqumo esibalulekile sebhizinisi. Lo mhlahlandlela ophelele uhlola izimiso zokuklama, izindinganiso, izinketho zezinto, kanye nezicelo ezithile zemikhakha yale mikhaya emithathu eyinhloko yezixhumi ezisheshayo zaseYurophu. Ekupheleni kwalolu hlahlobo, uzoba nenkambiso ecacile yokufanisa okufanele okufanele nezidingo zakho zokusebenza, kusekelwe ngesiqondiso sochwepheshe esitholakala nge-Varicpand International. Sizophinde sihlolisise ukuthi ukukhethwa kwezixhumi ezisheshayo kuthinta kanjani ukuphathwa kwezinto, ukuthobela imithetho, kanye nezindleko zokuba nazo, siqinisekisa ukuthi izinhlelo zakho zokuphatha uketshezi zisebenza kahle kakhulu ngaphansi kwezimo eziyinselele.

Ama-coupling e-UNI, aqanjwe ngegama lenhlangano yezindinganiso kazwelonke yase-Italy (Ente Nazionale Italiano di Unificazione), amele enye yezinhlelo zokuxhuma ezisheshayo ezamukelwa kakhulu ezolimo lwaseMedithera kanye nemililo yezimboni. Lezi zixhumi, ezibizwa nangokuthi ama-coupling ase-Barcelona/Uni ezimakethe ezithile, zibonakala ngokwakhiwa okune-thread noma okuxhuma ngokushesha okuvumela ukuxhunyelelwa kwamanzi okusheshayo ngaphandle kwamathuluzi akhethekile. Indinganiso ye-UNI ichaza imingcele eqondile yobukhulu nomfutho, okwenza zithandwe kakhulu ezinhlelweni zokunisela, ukudluliswa komanyolo, kanye nezicelo zomlilo ezinomfutho ophansi kuya ophakathi. Uma kuqhathaniswa nezinye izinhlobo zokuxhuma ezisheshayo, izixhumi ze-UNI zinikeza ibhalansi phakathi kokubiza kancane nokwethembeka komsebenzi, yize zingavunyelwe ukuthi zenzelwe imifutho edlulele etholakala kwezinye izindawo zezimboni. Indlela yokuxhuma ngokuvamile ihlanganisa i-lug yomuntu wesilisa noma iphiniphi elibamba isamukeli sowesifazane, esiqiniswe ngendandatho yokukhiya noma isibambo, siqinisekisa uphawu oluphephile ngesikhathi sokusebenza okuqhubekayo. I-Varicpand International inikeza uhla oluphelele lwama-coupling e-UNI ezintweni ezifana ne-aluminium, i-brass, ne-stainless steel, ehlangabezana nezidingo ezahlukene zokuhambisana namakhemikhali nokumelana nokugqwala. Ezinhlanganweni ezisebenzisana ezolimo kanye nezinsizakalo zomlilo zikamasipala ezisebenza e-Italy nasezifundeni ezizungezile, ama-coupling e-UNI ahlala eyisinqumo esisebenza kahle kwezindleko futhi esihambisana nezindinganiso.

Ama-coupling e-GOST, avela ohlelweni lwamazwe aseRussia lwezindinganiso zesifundazwe (Gosudarstvennyy Standart), enzelwe ukuqina okunamandla nokusebenza okuthembekile ezimweni ezinzima. La ma-coupling asheshayo asetshenziswa kabanzi ekukhiqizweni kukaphethiloli negesi, ekucubunguleni okuyikhemikhali, nasezinhlelweni zezimboni ezisindayo lapho ukudlidliza, ukushintsha kwezinga lokushisa, kanye nengcindezi yemishini kuyinselele yansuku zonke. Umklamo uvame ukuba nomshini wokuvala onamandla ongamelana nokwanda komfutho ophezulu nemijikelezo ephindaphindayo yokuxhuma-nquma ngaphandle kokudicilela phansi ubuqotho besitembu. Ngokungafani nomklamo we-Storz ongabheki ubulili noma uhlelo oluxhunywe ngentambo lwe-UNI, ama-coupling e-GOST avame ukusebenzisa i-pin-lug noma i-bayonet-style engagement enikeza ukukhiya okunamandla kwemishini, kunciphisa ubungozi bokunqamuka okungalindelekile. Izinga lihlanganisa ububanzi obuhlukahlukene bamasayizi namazinga omfutho, ngezinto ezifaka insimbi esezingeni eliphezulu, ithusi, ne-aluminium ukuze zihambisane nezinto ezithile ezifana ne-crude oil, udaka lokumba, namakhemikhali anolaka. Ngenkathi ama-coupling e-GOST angase angabi ajwayelekile eNtshonalanga Yurophu njengama-variant e-Storz noma e-UNI, abalulekile ezinkampanini ezisebenza eMpumalanga Yurophu, e-Central Asia, noma kunoma yisiphi isimo esidinga ukuhambisana nemithetho yezobuchwepheshe yaseRussia. Ukukhetha i-coupling ye-GOST efanele kudinga ukucatshangelwa ngokucophelela ububanzi bezinga lokushisa, ukuchayeka kumakhemikhali, nezidingo zokuqinisekiswa, futhi i-Varicpand International ingahlinzeka ngama-coupling aqinisekisiwe e-GOST&Rotta ahlangabezana nalezi zidingo eziqinile ngaphandle kokudicilela phansi izikhathi zokulethwa.

Ama-coupling ase-Storz amele umqondo wokuklama ovuselela umhlaba emkhakheni wama-quick coupling: uhlelo oluphelele olungenabo ubulili lapho izinhlangothi zombili zifana, okuvumela noma yimaphi ama-fittings amabili ase-Storz ukuthi axhumane ngaphandle kwesidingo sezinto zikaduna nezensikazi. Kwakhiwa eJalimane ekuqaleni, leli zinga laseYurophu lama-quick fitting selibe umgogodla wokusebenza kwezomlilo zesimanje kulo lonke izwekazi, kanye nasemasimini okuhlinzekwa ngamanzi, ukunisela, kanye nezinhlelo zokupholisa zezimboni. Ukuxhumana kufezekiswa ngomshini olula wokujika ikota olubandakanya izimbazo ezihlangene, olunikeza umuzwa wokuxhuma osheshayo nowokuzenzakalelayo ngisho nasezikhathini ezinzima eziphuthumayo. Ngoba akukho ukulungiswa futhi akukho sidingo sokulungisa izingxenye zikaduna nezensikazi, ama-coupling ase-Storz anciphisa kakhulu isikhathi sokulungisa kanye nephutha lomuntu. Umklamo uphinde ukhuthaze amazinga okugeleza aphezulu ngenxa yokuphazamiseka kwangaphakathi okuncane, okubalulekile kumaphampu ezomlilo kanye nezinhlelo ze-hydrant. Atholakala ngosayizi kusuka ku-25 mm kuye ku-150 mm futhi ngezinto ezifana ne-aluminium, ithusi, insimbi engagqwali, ne-polypropylene, ama-coupling ase-Storz ahlinzeka ngokuguquguquka okungajwayelekile. I-Varicpand International ihlinzeka ngokukhethwa okuphelele kwama-coupling ase-Storz nezesekeli, okuhlanganisa izinhlobo ze-aluminium nensimbi engagqwali, iqinisekisa ukuthi iminyango yomlilo kanye nabaphathi bamanzi ezimboni banokufinyelela ezintweni eziqinisekisiwe, ezinokusebenza okuphezulu. Ubulula obungokwemvelo bohlelo lwe-Storz buphinde benze lula ukuphathwa kwezinto, njengoba iminyango idinga ukugcina uhlobo olulodwa kuphela lwe-coupling end end kunokuba izethi zikaduna nezensikazi ezihlangene.

Uma uhlola izixhumi ze-UNI vs GOST vs Storz, kubalulekile ukuhlola izici ezimbalwa ezibalulekile: umqondo wokuklama, ukuhambisana nengqalasizinda ekhona, amazinga okucindezela nokushisa, kalula ukusetshenziswa, nezidingo zokugcinwa. Umklamo we-Storz uphumelela ngesivinini nokulula ngenxa yokusebenza kwawo okungenabo ubulili okuyisigamu sokujikeleza, okwenza kube ukukhetha okuncanyelwayo ekuphenduleni kwezimo eziphuthumayo nasekudluliseleni amanzi okukhulu. Izixhumi ze-UNI, ezinezixhumi ezinezintambo noma ezisheshayo, zinikeza indlela yendabuko eqondwa kahle ngabasebenzi bezolimo kodwa zingadinga isikhathi esiningi nokunakekelwa ukuze kufezekiswe ukuxhumana okungavuqi. Izixhumi ze-GOST zibeka phambili ukuqina ngaphezu kwakho konke, ngezinqubo zokukhiya ezimelana nokuxegiswa ukudlidlizela nokulimala komshini, yize zingase zibe nzima futhi zingabi nokuqonda kwabasebenzi abangafundisiwe. Ngokuya ngokumiswa, i-Storz ilawulwa yi-European Norms (EN 14423 namazinga ahlobene), iqinisekisa ukusebenzisana okubanzi phakathi kwabakhiqizi namazwe. I-UNI ilandela amazinga kazwelonke ase-Italy aqashelwa kabanzi kodwa angahlali ngokushintshana nezinye izinhlelo zaseYurophu. Ukuhambisana kwe-GOST kuyimpoqo emisebenzini eRussia naseCommonwealth of Independent States (CIS), kodwa lezi zixhumi zingadinga ama-adaptha ukuze zisebenze nemishini yasentshonalanga. Amazinga okucindezela ayahlukahluka: izixhumi ze-Storz ngokuvamile zibamba kufika ku-16 bar kumamodeli ajwayelekile, kanti izinhlobo ze-GOST zezimboni zingeqi ku-25 bar, futhi izixhumi ze-UNI ngokuvamile zisebenza ebangeni lika-6 kuye ku-12 bar. Izidingo zokugcinwa nazo ziyahlukahluka: izixhumi ze-Storz zidinga ukugcotshwa njalo kwezingxenye ezihambayo, kanti izintambo ze-UNI zingadinga ukuhlanjululwa kanye nezinto zokuvimbela ukugqwala, futhi izinqubo ze-bayonet ze-GOST kufanele zihloliswe ukuguga ezindaweni zokukhiya.

Ukusetshenziswa kwezixhumi ze-UNI, GOST, ne-Storz emhlabeni wangempela kubonakala kakhulu lapho kuhlolwa ukwamukelwa kwazo ezimbonini ezithile. Emililweni yomlilo, i-Storz standard ibusa kakhulu eYurophu ngenxa yesivinini sayo esingaphezu kokunqotshwa kanye nomklamo wayo ongabheki ubulili, ovumela abacimi bomlilo ukuthi baxhume izivuvu ngemizuzwana ngaphandle kokufuna iziphetho zikaduna nezikadede ezifanayo. Imicishamlilo yaseJalimane, yaseFrance, neyesiDutch ithembele kakhulu ezixhumi ze-Storz ezimishini yamanzi, amaphampu, kanye nezinsiza zokundiza. Ngokuphambene, imicishamlilo yase-Italy kanye nezinhlangano zezolimo zivame ukusebenzisa izixhumi ze-UNI, ezihlala ziqinile engqimeni kazwelonke yezinethiwekhi zokunisela kanye nemililo yasemakhaya. Imboni kawoyela negesi eRussia, eKazakhstan, kanye namazwe e-CIS cishe ivumela kuphela izixhumi ze-GOST ngenxa yokuthobela imithetho kanye nesidingo sezixhumi eziqinile ezingabhekana negesi emuncu, uwoyela oluhlaza, kanye nomusi onomfutho ophakeme. Izindawo zokwelapha amanzi, izimboni zamaphilisi, kanye nokucubungula ukudla kuvame ukwamukela indlela exubile: kusetshenziswa i-Storz amanzi ahlanzekile kanye nemigqa yokudlulisa ejwayelekile, kuyilapho kugcinwa i-UNI noma i-GOST yezinhlelo ezithile zokubeka amakhemikhali noma ezishisayo. I-Varicpand International isebenza kulezi zimboni zonke ngokunikeza imigqa yemikhiqizo ekhethekile njengezixhumi ze-Storz ezisensimbi engagqwalisiwe ezindaweni ezonakalisa kanye nezinhlobonhlobo ze-GOST ze-aluminium zezicelo zamafutha ezibucayi ngesisindo. Ukuqonda i-standard yokuxhuma ebusayo esifundeni sakho sezindawo kanye nomkhakha wezimboni kubalulekile ukuqinisekisa ukuhlanganiswa okungenamaphutha nemishini ekhona kanye nezimboni zokuhlinzeka.

Ukwakheka kwezinto ze-quick coupling kuthinta ngqo impilo yayo yokusebenza, ukuhambelana namakhemikhali, kanye nezindleko zokuba nayo isiyonke.Ama-couplings e-Aluminum Storz anikeza isilinganiso esihle kakhulu samandla kuye kesisindo nokumelana nokugqwala ngokwemvelo, okwenza alungele imishini ephathwayo yokucisha umlilo kanye nokudlulisa amanzi lapho ukonga isisindo kubaluleke kakhulu.Ama-couplings e-Brass Storz ahlinzeka ngokusebenza kahle kakhulu kwe-machining kanye nezakhiwo zokulwa namagciwane, okuyizinto ezizuzisayo ezinhlelweni zamanzi okuphuza kanye nezicelo zokudla. Kumakhemikhali agqwalisa kakhulu, amanzi olwandle, noma izinga lokushisa elidlulele,ama-couplings e-stainless steel Storz(ngokuvamile 304 noma 316L) yikho okuncanyelwayo, enikeza ukumelana okungajwayelekile nokugqwala okubangelwa izimbobo nokugqwala okungaphakathi. Izinhlobo ze-Polypropylene ziyatholakala emanzini acwebile kakhulu namakhemikhali anolaka lapho ukungcola kwensimbi kufanele kugwenywe. Izixhumi ze-UNI ne-GOST zilandelwa ingqikithi efanayo yezinto: Izixhumi ze-UNI ngokuvamile zenziwa nge-aluminium ezosetshenziswa ezolimo nobhedu ezokucisha umlilo, kanti izixhumi ze-GOST zivame ukuba nensimbi ye-carbon enezendlalelo zokuzivikela noma insimbi engagqwali ezosetshenziswa emafutheni. Lapho ukhetha isixhumi, hlola njalo izitifiketi zezinto zomkhiqizi nezilinganiso zokucindezela-lokushisa. I-Varicpand International ihlinzeka ngemininingwane yezobuchwepheshe yazo zonke izinketho zezinto, isiza amakhasimende ukuthi afanise i-alloy yesixhumi nezinto ezithile, izinga lokushisa lokusebenza, kanye nezimo zemvelo zendawo yawo. Ukumelana nokugqwala akuyona nje into yohlobo lwezinto; ukwelashwa kwendawo njenge-anodizing, i-passivation, noma ukugqoka kwe-epoxy kungaqhubeka nokwandisa impilo yesevisi ezindaweni ezinolaka.

Ukukhetha phakathi kwezixhumi ze-UNI, GOST, kanye ne-Storz akubandakanyi nje kuphela imininingwane yezobuchwepheshe; abaholi bokuthenga kufanele futhi bacabangele ukuthobela imithetho, ukwenziwa okujwayelekile kwezinto ezigciniwe, kanye nezindleko zokusebenza zesikhathi eside. Ukuthobela Iziqondiso ZaseYurophu (njengePressure Equipment Directive 2014/68/EU) kanye namazinga kazwelonke kuyimpoqo ukuze kuqinisekiswe ukuphepha kanye nomshwalense. Izixhumi ze-Storz eziqinisekisiwe ku-EN 14423 zinikeza indlela ecacile yokuthobela kulo lonke elase-EU, kanti izixhumi ze-UNI ezihambisana namazinga ase-Italy zingamukelwa ezindaweni ezithile zezolimo nezomkhandlu. Izixhumi ze-GOST zidinga isitifiketi esihlukile (i-GOST-R noma i-EAC) ukuze zisetshenziswe ku-Customs Union yaseRussia, Belarus, kanye neKazakhstan. Ukwenziwa okujwayelekile kwezinto ezigciniwe kungenye into ebalulekile: ukwamukela uhlelo lwe-Storz olungenabo ubulili lunganciphisa inani lezinhlobo zezinto ezihlukene ngama-50%, kwenze lula ukuphathwa kwesitolo futhi kunciphise ingozi yezingxenye ezingafani. Izindleko zokusebenza zihlanganisa hhayi kuphela intengo yokuqala yokuthenga kodwa futhi nomsebenzi wokugcinwa, izindleko zokuyeka ukusebenza ngenxa yokuhluleka kokuxhuma, kanye nezindleko zokugcina izinhlobo eziningi zama-adapter. I-Varicpand International iluleka amaklayenti ukuthi enze isheke eliphelele sezinto zawo ezikhona ezixhumeneyo kanye nezinhlelo zokwanda esikhathini esizayo ngaphambi kokwenziwa okujwayelekile ohlelweni olulodwa. Kwezisebenzi okufanele zisebenze nezinga eliningi, ukutshala ezixhumenini zama-adapter ezisezingeni eliphezulu kungalungisa umehluko ngaphandle kokudinga ukuguqulwa okuphelele kwemishini ekhona. Ubuchwepheshe bomphakeli bubaluleke ngokufanayo: ukusebenza nomlingani njenge-Varicpand International kuqinisekisa ukufinyelela emikhiqizweni eqinisekisiwe, imibhalo yezobuchwepheshe, kanye nokwesekwa ngemuva kokuthengisa okunciphisa ingozi yamaphutha okucaciswa.

Cha, ukuxhumana okuqondile phakathi kwezindinganiso ezihlukene akunakwenzeka ngaphandle kwe-adapter ngoba izindlela zokukhiya namaphrofayili osayizi ahlukile. Noma kunjalo, i-Varicpand International inikeza ama-adapter coupling aguqula phakathi kwezindawo ze-Storz, UNI, kanye ne-GOST, okuvumela ukusebenzisana ezindaweni ezinezindinganiso ezixubile. Lawa ma-adapter atholakala ku-aluminium, ithusi, kanye ne-stainless steel ukuze kugcinwe ukumelana nokugqwala kanye nokuqina kwengcindezi.

Izixhumi ezijwayelekile ze-Storz ngokuvamile zilinganiswa kufika ku-16 bar (232 psi) enkonzweni yamanzi ezingeni lokushisa elijwayelekile. Izinhlobo zokucindezela okuphezulu ezinama-locking lugs aqinisiwe nezingxenye zodonga ezisindayo zingafinyelela kufika ku-25 bar. Njalo thintana nedatha yomkhiqizi imininingwane yemodeli ethile nezinga lezinto, njengoba izilinganiso zokucindezela zincipha ezingeni lokushisa eliphezulu.

Yebo, amagama athi UNI coupling kanye ne-Barcelona/Uni coupling ngokuvamile abhekisa kuso sonke isilinganiso esifanayo. Isibonelo se-Barcelona/Uni ngezinye izikhathi sisetshenziswa kwezohwebo lwamazwe omhlaba ukuhlukanisa lezi zixhumi kwezinye izilinganiso zase-Italy, kodwa imininingwane yobukhulu kanye nezingxenye zokuxhuma ziyafana. Amakhophi e-aluminum ne-brass ase-Barcelona/Uni ka-Varicpand International ahambisana ngokuphelele nesilinganiso se-UNI.

Ezindaweni ezinezindunduma eziphakeme njengemigqa yokudlulisa amafutha negesi, izindawo zokubhola, neziteshi zama-compressor, izixhumi ze-GOST zivame ukukhethwa ngenxa yendlela yazo eqinile yokukhiya izikhonkwane evimbela ukuxega ngaphansi kwezindunduma eziqhubekayo. Ukuxhumana okufana ne-bayonet kunikeza ukukhiya okunamandla okungokomshini okungathinteki kalula ukuze kuxhunulwe ngephutha uma kuqhathaniswa nezinhlelo zokujika ikota noma ezintambo.

Ukuhambisana namakhemikhali kuyinto eyinhloko okufanele icatshangelwe. Kumaladi namachloride, insimbi engagqwali engu-316L noma i-polypropylene iyatuswa. Kumalcali namadliquid angathathi hlangothi, i-aluminium noma i-brass ingase yanele. Njalo hlola imidiya neshadi lokuhambisana namakhemikhali bese uthintana nomphakeli ofana neVaricpand International, enikeza isiqondiso sokukhetha impahla futhi inganikeza izixazululo ezenziwe ngendlela efanele kumidiya enolaka.

Ukukhetha indinganiso efanele yokuxhuma okusheshayo kuyisinqumo samasu esithonya ukusebenza kahle, ukuphepha, nokulawula izindleko ezinhlelweni zokudlulisa uketshezi. Izixhumi ze-Storz ziyimpawu ezingafani nhlobo zokusebenza ngokushesha nokulula, okwenza zibe yisinqumo esihle kakhulu emililweni, ekusabalaliseni amanzi, nasemisebenzini ejwayelekile yezimboni lapho ukuxhuma nokunqamula ngokushesha kubalulekile. Izixhumi ze-UNI ziyaqhubeka nokusebenzela izimakethe zezolimo nezomlilo kamasipala kahle, ikakhulukazi eNingizimu Yurophu, ngenxa yengqalasizinda yazo esungulwe kahle nokusebenza kahle kwezindleko. Izixhumi ze-GOST zinikeza ukuthembeka okunamandla okufunwa abasebenzi bakaphethiloli negesi kanye nezimboni ezisindayo ezisebenza ezindaweni ezinzima noma ngaphansi kwemithetho eqinile ye-CIS. Okubalulekile empumelelweni akusho ukukhetha indinganiso eyodwa kunabanye, kodwa ukuqonda izidingo ezithile zohlelo lwakho, isifunda sakho sezindawo, kanye nemvelo yokulawula. I-Varicpand International ingumngane wakho omethembayo ekuhambeni kule ndawo eyinkimbinkimbi, enikeza iqoqo eliphelele lezixhumi ze-Storz, UNI, ne-GOST ezintweni eziningi, kanye nobuchwepheshe bezobuchwepheshe ukuqinisekisa ukukhetha okulungile nokuhambisana. Sikumema ukuthi uhlole i-amakhasi omkhiqizo ukuze uthole imininingwane eningiliziwe kanye nemibhalo yezitifiketi, futhi ukuthinta ithimba lethu ukuze uthole iseluleko esenziwe ngendlela efanele sokufeza izinhlelo zakho zokuxhuma izidliquid.
