Ipayipi le-hydraulicidivayisi iwumsebenzi oyinhloko wokufakwa kwemishini yamanzi.Izinga ledivayisi yepayipi ingenye yezikhiye zomsebenzi ojwayelekile wohlelo lwe-hydraulic.
1. Lapho uhlela futhi ufaka amapayipi, ukucatshangelwa okuphelele kufanele kunikezwe izingxenye, izingxenye ze-hydraulic, amapayipi amapayipi, nama-flanges okudingeka axhunywe ngokusekelwe kumdwebo we-hydraulic schematic diagram.
2. Ukubekwa, ukuhlelwa, kanye nendlela amapayipi aya ngakhona kufanele kube okuhlanzekile futhi okujwayelekile, kube nezingqimba ezicacile.Zama ukukhetha ukuma kwepayipi enezingqimba noma eqondile, futhi ukungalingani kwamapayipi avundlile kufanele kube ≤ 2/1000;Ukungaqondile kwepayipi eliqondile kufanele kube ≤ 2/400.Hlola nge-level gauge.
3. Kufanele kube negebe elingaphezu kuka-10mm phakathi kwamapayipi ahambisanayo noma ahlanganayo.
4. Imishini yamapayipi iyadingeka ukuze kube lula ukulayishwa, ukuthulula, kanye nokulungiswa kwamapayipi, amavalvu asebenzisa amanzi amaningi, nezinye izakhi.Noma iyiphi ingxenye yepayipi noma ingxenye ohlelweni kufanele ikwazi ukuhlakazwa futhi ihlanganiswe ngokukhululeka ngangokunokwenzeka ngaphandle kokuthikameze ezinye izingxenye.
5. Uma ufaka amapayipi ohlelweni lwe-hydraulic, kuyadingeka ukuqinisekisa ukuthi ipayipi linezinga elithile lokuqina kanye nekhono lokulwa nokuzulazula.Izisekelo zamapayipi kanye nezinsimbi kufanele zifakwe ngokufanele.Amapayipi asontekile kufanele afakwe abakaki noma izinsimbi eduze nendawo yokugoba.Ipayipi akufanele lishiselwe ngokuqondile kubakaki noma isigxivizo sepayipi.
6. Ingxenye yepayipi akufanele yamukelwe amavalvu, amaphampu, nezinye izingxenye ze-hydraulic kanye nezinsiza;Izingxenye ezisindayo akufanele zisekelwe ngamapayipi.
7. Kuyadingeka ukucabangela izindlela eziwusizo zamapayipi amade ukuvimbela ukucindezeleka okubangelwa ukushintsha kwezinga lokushisa okubangela ukwanda nokufinyela kwamapayipi.
8. Kudingeka ukuthi kube nesisekelo esicacile sokuqala sezinto zokusetshenziswa zepayipi ezisetshenziswayo, futhi amapayipi anempahla eluhlaza engaziwa awavunyelwe ukusetshenziswa.
9. Amapayipi e-hydraulic system anobubanzi obungaphansi kuka-50mm angasikwa ngesondo lokugaya.Amapayipi anobubanzi obungu-50mm noma ngaphezulu ngokuvamile kufanele asikwe ngokucubungula ngomshini.Uma ukusika igesi kusetshenziswa, kuyadingeka ukusebenzisa izindlela zokucubungula ngomshini ukususa izingxenye ezishintshile ngenxa yokuhlelwa kokusika igesi, futhi ngesikhathi esifanayo, i-welding groove ingavulwa.Ngaphandle kwepayipi likawoyela elibuyayo, akuvunyelwe ukusebenzisa isisiki sokuxova sohlobo lwe-roller ukusika ingcindezi epayipini.Kudingekile ukusika ubuso bepayipi flat futhi ususe ama-burrs, isikhumba se-oxide, i-slag, njll. Indawo enqunyiwe kufanele iqonde nge-axis yepayipi.
10. Uma ipayipi lenziwe ngezigaba eziningi zamapayipi kanye nezingxenye ezisekelayo, kufanele litholwe ngamunye ngamunye, ligcwaliswe ingxenye eyodwa, lihlanganiswe, bese lihlonyiswa ngesigaba esilandelayo ukuvimbela amaphutha aqoqwe ngemva kokushisela okukodwa.
11. Ukuze kuncishiswe ukulahlekelwa kwengcindezi ngokwengxenye, ingxenye ngayinye yepayipi kufanele ivimbele ukwanda okusheshayo noma ukuncipha kwengxenye enqamulayo kanye nokusonteka nokujika okubukhali.
12. Ipayipi exhunywe ekuhlanganyeleni kwepayipi noma i-flange idinga ukuba ingxenye eqondile, okungukuthi, i-axis yalesi sigaba sepayipi kufanele ihambisane futhi ihambisane ne-axis ye-pipe joint noma i-flange.Ubude bale ngxenye yomugqa oqondile kufanele bube bukhulu noma bulingane izikhathi ezi-2 ubukhulu bepayipi.
13. Indlela yokugoba ebandayo ingasetshenziselwa amapayipi anobubanzi obungaphandle obungaphansi kuka-30mm.Uma ububanzi obungaphandle bepayipi buphakathi kuka-30-50mm, ukugoba okubandayo noma izindlela zokugoba ezishisayo zingasetshenziswa.Lapho ububanzi obungaphandle bepayipi bukhulu kuno-50mm, indlela yokugoba eshisayo ivame ukusetshenziswa.
14. Abashiseli abashisela amapayipi adonsa amanzi kufanele baphathe isitifiketi sokufaneleka sokushisela sepayipi elinengcindezi ephezulu.
15. Ukukhethwa kobuchwepheshe bokushisela: I-acetylene gas welding isetshenziselwa ikakhulukazi amapayipi anogqinsi oluvamile lwe-2mm noma ngaphansi kwamapayipi ensimbi ye-carbon.I-arc welding isetshenziselwa ikakhulukazi amapayipi ane-carbon steel pipe odongeni ubukhulu obukhulu kuno-2mm.Kungcono ukusebenzisa i-argon arc welding ukushisela amapayipi.Kumapayipi anogqinsi olungaphezulu kuka-5mm, i-argon arc welding izosetshenziselwa ukwakhiwa futhi i-Arc welding izosetshenziselwa ukugcwalisa.Uma kunesidingo, i-welding kufanele yenziwe ngokugcwalisa umgodi wepayipi ngegesi yokulungisa.
16. Izinduku zokushisela kanye nama-fluxes kufanele amataniswe nempahla yamapayipi ashiselwe, futhi izimpawu zawo zokuthengisa kufanele zisekelwe ngokucacile ezintweni ezibonakalayo, zibe nesitifiketi sokufaneleka komkhiqizo, futhi zibe phakathi nesikhathi esiwusizo sokusebenzisa.Izinduku zokushisela kanye nama-fluxes kufanele zomiswe ngokwemithetho yebhukwana lomkhiqizo wazo ngaphambi kokusetshenziswa, futhi kufanele zigcinwe zomile ngesikhathi zisetshenziswa futhi zisetshenziswe ngosuku olufanayo.I-electrode coating kufanele ikhululeke ekuweni nokuqhekeka okusobala.
17. Ukushisela izinqe kufanele kusetshenziselwe ukushisela amapayipi amanzi.Ngaphambi kokushisela, ukungcola, amabala kawoyela, umswakama, namabala okugqwala ebusweni be-groove nezindawo eziseduze ezinobubanzi obuyi-10-20mm kufanele zisuswe futhi zihlanzwe.
18. Izinqe zokushisela kufanele zisetshenziselwe ukushisela phakathi kwamapayipi nama-flange, nama-flange ahlabayo akufanele asetshenziswe.
19. I-butt welding kufanele isetshenziselwe ukushisela amapayipi namapayipi ahlangene, futhi i-penetration welding akufanele isetshenziswe.
20. Ukushisela izinqe kufanele kusetshenziselwe ukushisela phakathi kwamapayipi, futhi ukushisela ukungena akuvunyelwe.
