Jiangsu New Silver Leaf Transmission Ltd Precision gear oil composition and function of the system are as follows:
Lubricate: to lubricate the pump - motor group, filters, valves and piping and other components for pressure and flow rate required lubrication system and control system cleanliness.
Safety valve on the pump set pressure 10bar, to prevent damage to the high pressure system components. When the oil temperature is low or when the filter cartridge pressure greater than 4bar, open the check valve on the filter, hydraulic oil only through the coarse filter 50μ; when the temperature is gradually increased, the differential pressure is lower than 4bar filter, the hydraulic oil through 10μ and 50μ two-stage filtration. In either case, unfiltered hydraulic oil must not be allowed to enter the gear box lubricating parts. When sump temperature is below 30 ° C, the filter differential pressure transmitter alarm signal is inactive; and when the oil sump temperature exceeds 30 ° C, when the pressure reaches 3 bar, this time an alarm signal to be effective, must replace the cleaning cartridge in two days.
