Usage & Feature:
ZB4-500 electric oil pump is the power resource and control device for wire tension, which is used in conjunction with various jacks(Nom. pressure 50MPa),as well as other low flow or high pressure hydraulic equipments. ZB4-500s electric oil pump is based on ZB4-500. It features trinity 3-way valve, simultaneous operation of tensioning and pressing.
Specifications: ZB4-500 Hydraulic pump, ZB2-500 Hydraulic pump
ZB4-500 electric oil pump consists of pump, control valve, cabinet, and internal pipes.
P2 Pump Structure
2. The left and right valve bodies which are the same structure constitute the pump. Each valve body consists of throttle valve, unload valve, one-way valve, pressure meter,relief valve, intake nozzle, output nozzle and oil-return nozzle. (P3)
The throttle valve is a tunable wedge valve used to adjust input flow of the cylinder.The unload valve is a kind of tunable globe valve(open---unload, close---intake oil). The one-way valve of ball type stabilizes the pressure of working system. The relief valve is a tunable overflow valve used to adjust the system pressure of 50MPa.
(P3) Control Valve Structure
Using & maintenance:
1.Use #46 oil, keep it clean, filter it frequently, and replace it regularly. The height of oil in the cylinder is 150-200mm. To assure the function of greasing, the oil level mustn't be lower than 150mm, and the temperature mustn't be higher 60ºC.
2. Operating for the first time
Before operation, air exists in each oil container, please open the control valve, idle the oil pump, expel the air till bubbles in oil-return hose vanish.
3. Relief valve adjustment
Seal the output nozzle, open the throttle valve, close the unload valve. Then switch the pump,close the throttle valve, and read the pressure meter as well as adjust the unload valve till designed pressure. The adjusting pressure of relief valve is 10%-15% higher than working pressure.
4. Pressure meter check-out
To assure the quality of operation and accuracy of measurement, check the pressure meter as the regulation.
