• Cov chaw khaws cia yuav tsum tsis muaj cov khoom corrosive thiab gases.• Txhawm rau tiv thaiv kev puas tsuaj rau cov ntsaws ruaj ruaj, tsis txhob siv cov khoom siv ozone (xws li mercury-vapor teeb, cov cuab yeej siv hluav taws xob, lub tshuab hluav taws xob, cov khoom hluav taws xob thiab / lossis hluav taws xob tawm. ) nyob rau hauv cov chaw cia khoom.• Cov chaw khaws cia yuav tsum qhuav. Pom zoo cov av noo tsawg dua lossis sib npaug li 60%.• Zoo tagnrho cov kabmob kub: +5 degree rau +20 degree .• Qhov ntsuas kub tsawg kawg nkaus: −50 degree .• Cia siab tshaj plaws: +60 degree .• Khaws tawm ntawm tshav ntuj ncaj qha.• Tsis txhob tso cov axial piston units thiab khaws cia rau hauv qhov kev poob siab.• Tsis txhob khaws cov axial piston unit ntawm lub tsav ncej lossis Cov khoom sib dhos, xws li cov twj tso kua mis lossis cov li qub.• Yog xav paub ntxiv txog kev khaws cia, saib Table 7.▶ Tshawb xyuas lub axial piston unit txhua hli kom ntseeg tau tias kev khaws cia zoo.

Kev xaiv kom raug ntawm cov kua dej hydraulic yuav tsum muaj kev paub txog kev ua haujlwm ntawm qhov kub thiab txias ntawm qhov ntsuas kub: 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; 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 hauv 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.
