oil main tank circulating pump suction filter
The filter element OF3-08-3RV-10 work with circulating pump. In the process of EH oil flushing and filtering, the circulating pump (put the oil source bypass filter into operation) shall be started and operated continuously for 24 hours. The EH oil pressure shall remain unchanged at 4.5MPa until the oil quality test is qualified and the flushing and filtering work is completed.
Because the pressure of fire-resistant oil is high, the clearance of hydraulic moving parts is small, and the minimum clearance of servo valve is 5 ~ 10um, the flushing filtration shall be 3 during unit maintenance μ M precision flushing to keep the oil within the safe cleanliness range can achieve the safety of oil pump and servo valve in the protection system.
The pressurized oil return filter element OF3-08-3RV-10 is installed on the EH oil station. The fire-resistant oil will return to the oil tank after one cycle of the system. It must be filtered before returning to the oil tank to ensure that the cleanliness of the fire-resistant oil returned to the oil tank meets the standard. The filter’s working filtering accuracy 10μm. we suggest that replace it twice a year under normal working conditions.
