Paub meej txog kev xaiv cov kua dej hydraulic
Kev xaiv kom raug ntawm cov kua dej hydraulic yuav tsum muaj kev paub txog kev ua haujlwm ntawm qhov kub thiab txias hauv kev sib raug zoo rau qhov kub thiab txias: hauv
ib tug kaw Circuit Court kub Circuit Court. Cov kua dej hydraulic yuav tsum raug xaiv kom qhov kev khiav hauj lwm viscosity nyob rau hauv kev khiav hauj lwm kub nyob rau hauv qhov zoo tshaj plaws ntau yam - qhov ntxoov ntxoo ntawm daim duab xaiv. Peb pom zoo kom xaiv cov chav kawm viscosity siab dua hauv txhua kis. Piv txwv li: Ntawm qhov ntsuas kub ntawm X degree kev khiav hauj lwm kub ntawm 60 degree yog teem. Nyob rau hauv qhov zoo tshaj plaws kev khiav hauj lwm viscosity ntau (qhov chaw ntxoov ntxoo) no sib raug rau cov chav kawm viscosity VG 46 los yog VG 68; yuav tsum tau xaiv: VG 68. Thov nco ntsoov: Cov ntaub ntawv ntws kub, uas yog cuam tshuam los ntawm lub siab thiab ceev, yog ib txwm siab tshaj qhov ntsuas kub ntawm Circuit Court. Nyob rau hauv tsis muaj cov ntsiab lus nyob rau hauv lub system yuav kub siab tshaj 115 degree. Yog tias cov xwm txheej saum toj no tsis tuaj yeem khaws cia vim muaj kev ua haujlwm tsis zoo, thov nrog peb tham.
Hydraulic kua
Ua ntej pib qhov kev npaj, thov mus saib peb cov ntaub ntawv RE 90220 (cov roj ntxhia), RE 90221 (ib puag ncig siv tau cov kua dej hydraulic) thiab RE 90223 (HF hydraulic fluids) rau cov ncauj lus kom ntxaws txog kev xaiv cov kua dej hydraulic thiab daim ntawv thov. Lub twj tso kua mis hloov pauv A4VG tsis haum rau kev ua haujlwm nrog HFA, HFB thiab HFC. Yog tias HFD lossis ib puag ncig tau siv cov kua dej hydraulic, cov kev txwv ntawm cov ntaub ntawv kev lag luam thiab cov ntsaws ruaj ruaj tau hais hauv RE 90221 thiab RE 90223 yuav tsum raug soj ntsuam. Thaum xaj, thov qhia cov kua dej siv hydraulic.
