Khiqiza Inqubo kanye nezinzuzo
Insimbi ye-billet, ngemuva kokudweba okunembayo, ukwelashwa okungenayo i-oxidation nokugqamile kokushisa (isifunda se-NBK), ukuhlolwa okungabhubhisi, ukugudluzwa komfutho ophezulu kanye nokucocwa kwe-asidi yembobo yangaphakathi yepayipi lensimbi, ukwelashwa kukawoyela ovimbela ukugqwala kwezindonga zangaphakathi nezingaphandle. wepayipi lensimbi, kanye nokwelashwa kokuvimbela uthuli kuzo zombili iziphetho zekhava.
1. Izindonga zangaphakathi nezingaphandle zepayipi lensimbi azinalo ungqimba lwe-oxide;
2.Withstand high pressure, akukho ukuvuza, ukunemba okuphezulu, ukushelela okuphezulu;
3. Ukugoba okubandayo ngaphandle kokuguqulwa, ukunwetshwa, ukucaba ngaphandle kokuqhekeka;
4. Ukwelashwa kokuvimbela ukugqwala kwamanzi.
I-DIN 2391 ipayipi yensimbi engenamthungo Isicelo
IHydraulic system, umshini wokubumba umjovo, umshini wokubacindezela, ukwakha umkhumbi, umshini wokudonsa amanzi we-EVA onegwebu, ipayipi lensimbi lomshini wokusika oqondile we-hydraulic, umshini wokuthunga izicathulo, izinto ezisebenza ngogesi, ipayipi likawoyela elinengcindezi ephezulu, ipayipi likawoyela osebenza ngogesi, ijoint ferrule, ipayipi lensimbi, imishini yerabha. , imishini yokubumba, imishini yokubulala, imishini yobunjiniyela, ipayipi lensimbi elinomfutho ophezulu weloli lephampu likakhonkolo, imoto yokuthuthwa kwendle, imboni yezimoto, imboni yokwakha umkhumbi.Injini kadizili, injini evuthayo yangaphakathi, i-compressor yomoya, imishini yokwakha, imishini yezolimo neyamahlathi, njll., efakwe amalunga epayipi ensimbi, amajoyinti emikhono, namapayipi kawoyela anengcindezi ephezulu.
