Ijoyinti yerabha eguquguqukayo evamile ijoyinti yerabha yebhola elilodwa, kanye neukunciphisa ukuhlanganiswa kwenjoloba yokwandisaiyinhlanganisela yenjoloba ekhethekile eyakhiwe ngesisekelo sebhola elilodwa elijwayelekile
Ijoyinti yokunciphisa injoloba enwetshiwe yakhiwe ngama-flange amabili anobubanzi obuhlukene kanye nomzimba wokunweba werabha phakathi. Ama-flange emikhawulweni yomibili angaxhunywa nokufakwa kwamapayipi wesistimu yamapayipi. Esimeni sokunwetshwa okushisayo noma ukugudluzwa kwepayipi, indikimba yenjoloba enwebayo inganwetshwa futhi ifinyeze ukunwetshwa Kwamahhala, imunce ukususwa kanye nengcindezi yepayipi, futhi igcine ukuzinza kwesistimu yamapayipi.
Njengempahla yesinxephezelo sepayipi, ngokuvamile yenziwa ngenjoloba. Umsebenzi wawo oyinhloko ukuqeda ukucindezeleka nokuguqulwa okubangelwa ukwanda kwezinga lokushisa, ukudlidliza, ukugudluzwa kanye nezinye izizathu ohlelweni lwamapayipi, ukuze kuncishiswe umthwalo wesistimu yamapayipi futhi andise impilo yesevisi yepayipi.Ngaphezu kwalokho, indlela yokunciphisa ijoyinti lokunwetshwa kwenjoloba linciphisa ukunwetshwa kukathayela. Amajoyinti anwebekayo anama-flanged ngokuvamile akhiwa ama-flange ensimbi engagqwali namajoyinti erabha ensimbi engenasici.
Uma kuqhathaniswa nezinye izinhlobo zejoyinti lokunweba, ukwehlisa ukunwetshwa kwejoyinti kunezici ezilandelayo:
1. Ingakwazi ukuxhuma amapayipi ama-diameter ahlukene, okwenza kube lula ukuxhuma ohlelweni lwamapayipi.
2. Yenziwe ngezinto zenjoloba, inokumelana nokugqwala okuhle nokumelana nokugqoka, nempilo ende yenkonzo.
3. Ukufakwa kalula, ukugcinwa kalula, kanye nomthelela omncane ohlelweni lwamapayipi.
Ukunciphisa ukuhlanganiswa okuguquguqukayo kwenjoloba kusetshenziswa kabanzi ohlelweni lwamapayipi emikhakheni yemboni yamakhemikhali, i-petroleum, amandla, ukwakhiwa, ukufudumeza, njll., okunganciphisa ngempumelelo umthwalo wesistimu yamapayipi futhi kunwebe impilo yesevisi yepayipi.
Izinzuzo zokunciphisa ukujoyina kwenjoloba ngaphezu kokujwayelekileukuhlanganiswa kwenjoloba yokwandisazibonakala kakhulu kulezi zici ezilandelayo:
1. Ububanzi obubanzi bokusebenza: ukunciphisa ijoyinti lokunwetshwa kwenjoloba kungaxhuma amapayipi anobubanzi obuhlukene, futhi ububanzi bokusebenza bukhulu, kuyilapho ijoyinti elivamile lenjoloba eliguquguqukayo lingaxhuma kuphela amapayipi anobubanzi obufanayo.
2. Umthamo wesinxephezelo esinamandla: ngoba ingxenye ephakathi yomzimba wokunwetshwa kwenjoloba weukunciphisa ukuhlanganiswa kwenjoloba yokwandisai-conic, ingamelana nengcindezi enkulu futhi inamandla okunxeshezelwa aqinile lapho uhlelo lwamapayipi lususwa endaweni noma lukhubazekile.
3. Indawo yokufaka evumelana nezimo kakhudlwana: ububanzi be-flange bejoyinti lenjoloba elivamile lokunwetshwa luyafana nelomzimba onwebayo, futhi kufanele lufakwe kuzo zombili iziphetho zepayipi, kuyilapho ububanzi be-flange bokunciphisa ijoyinti lokunwetshwa kwerabha buhlukile kulokho umzimba wokunweba, futhi ungafakwa kunoma iyiphi indawo yepayipi.
4. Ukugcinwa okulungile kakhudlwana: ubude bokunciphisa ukunwetshwa kwejoyini lenjoloba bungalungiswa ngokuya ngezidingo zohlelo lwamapayipi, olulungele ukushintshwa nokugcinwa.
Ngamafuphi nje, ijoyinti encishisiwe yokunwetshwa kwenjoloba inobubanzi obubanzi bokusebenza, umthamo wesinxephezelo oqinile, indawo yokufaka evumelana nezimo kanye nemodi yokulungisa elula kakhulu kunejoyinti elijwayelekile lokunwetshwa kwenjoloba, elingahlangabezana kangcono nezidingo zesistimu yamapayipi.
