How it works: When a low pressure, high pressure pump through the high and low pressure check valve while oil, when working pressure greater than 2.5MPa when the press electric pump type, high pressure oil hydraulic control low pressure relief valve to open, low-pressure pump mortar dynamic load return oil (low pressure oil under high pressure oil does not work situation also has its own open low pressure overflow valve function. The valve for your safety) (2) 34SZHP 6M pressure hand valve for unloading the median three-way type valve, the valve is assigned rotary vane, its better stain resistance, commutation, reliable, easy maintenance, with packing function. Work in the tank liquid level should remain at the center line of the underlying oil presses electric pump pressure, to prevent pump cavitation. When refueling, use 120 mesh grease filter new oil filter out impurities. When the press is often used low pressure electric pump, filter cleaned once every two months, half a tank cleaning, and replace with new oil. Presses electric pump high-pressure electric pump presses Wuzhou _ _ Texas aerospace hydraulic provided by Dezhou City aerospace hydraulic machinery plant.
