1. The speed and pressure of the pump should not exceed the specified value, and long-term use should be avoided, otherwise the life of the hydraulic pump will be affected.

2. When the hydraulic pump is started, it should be jogged several times, and after the oil flow direction and sound are normal, it should run under low pressure for 5-10min, and then put into normal operation. Before the piston pump is started, the pump must be filled with clean working oil through the oil drain port on the casing.

3. The self-priming vacuum degree of the pump should be within the specified range, otherwise insufficient oil absorption will cause cavitation, noise and vibration.

4. If the inlet of the pump is specified with oil supply pressure, it should be guaranteed.

5. The oil must be clean, not mixed with mechanical impurities and corrosive substances, and the hydraulic system without a filter device on the suction pipeline must be refueled to the oil tank through the oil filter truck (filtration accuracy less than 25μm).

6. The leaking oil pipe of the pump should be unobstructed.

7. The pump with a long downtime should not be started at full load, and then used normally after idling for a period of time.

8. Check the condition of the filter, understand the quality, quantity and size of the blockage attachment, and remove it regularly.

9. Check the changes of hydraulic oil, changes in liquid level, check the temperature and viscosity of the oil, the degree of pollution and discoloration, and replace the hydraulic oil or make up the oil regularly.

10. Check the condition of each sealing point to prevent air from entering the pump or oil leaking outside the pump.

Rexroth Balancing Valve Installation Instructions Rexroth Balancing Valve Installation Instructions

1) Remove the protective covers on both sides of the flange end, and rinse and clean the valve when the valve is fully open. 2) Before the installation of the balance valve with actuator, the whole machine should be tested according to the specified signal (electricity or gas) (to prevent the vibration caused by transportation from affecting the performance).

Analysis of the reasons for the insufficient flow of Rexroth hydraulic pump plunger pump Analysis of the reasons for the insufficient flow of Rexroth hydraulic pump plunger pump

(1) Insufficient inhalation The reason is that the resistance in the suction line of the Rexroth piston pump is too high or the oil replenishment is insufficient. For example, the speed of the pump is too large, the liquid level in the oil tank is too low, the oil inlet pipe is leaking, and the oil filter is blocked. (2) The amount of leakage is too large The reason is the gap in the Rexroth piston pump ...
