Kev Ntsuam Xyuas Rau Kev Tshawb Xyuas:
1. Dej degradation:
{{0- Viscosity puas (Kinematic viscosity<40 cSt at 40°C).
- Air entrainment (foam stability >5 feeb ib astm D892).
2. Kev tivthaiv hnav:
- Axial piston pump wear plate delamination (clearance >15µm).
{-} Kev sib cav sib ceg Valve tshaj 5% FS.
Kho kev ntsuas:
-} Cov Khoom Noj Hluav Taws Xob:
-}} Xa roj qauv rau kev txheeb xyuas theem rau kev tshawb fawb ntxiv (icp} AES) los xyuas cov khoom ntxiv.
{{0-} hloov cov kua dej yog particle suav tau tshaj ISO 18/16/13.
- Twj Tso Cai Ua Tau:
{{0-}}}}}}}} Siv Bluke® 754, Txheeb xyuas cov neeg them nyiaj siab siab<200ms.
{{0- Rov ua cov twj nrog cov khub rotor / barrel sib dhos.
- valve valve ntsuas hluav taws xob:
-} Tau kho ls (thauj khoom ls (thauj khoom ls (thauj khoom siab) cov npoo siab rau 2.0 ± 0.3 MPa ntawm qhov chaw nres nkoj.
Cov Lus Qhia Ua Haujlwm:
{{0- Tswj HYDRAULIC roj kub ntawm 50-70℃thaum lub sijhawm ua haujlwm.
-}} Siv tau kaw {{1/2 lub voj uas dej ntws thaum cov roj hloov ib vickers i-286-s.
