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.

Precautions for the use of Rexroth hydraulic pump hydraulic oil
(1) Make sure that the hydraulic oil of Rexroth hydraulic pump is clean and prevent debris from entering the oil. Clean the tank thoroughly when changing the oil and filter it when refueling.
(2) Do not paint the inner wall of the oil tank to prevent precipitation in the oil.
(3) In order to prevent air from entering the hydraulic system, the oil return nozzle should be lower than the tank fluid.

How to select Rexroth solenoid valves
1. Select the solenoid valve according to the pipeline parameters: the diameter specification (i.e., DN) and the interface mode 1) determine the diameter (DN) size according to the on-site pipeline inner diameter size or flow requirements; 2) Interface mode, generally > DN50 to choose the flange interface, ≤ DN50 can be freely selected according to the user's needs. ...

The difference between Rexroth hydraulic pump and hydraulic motor
Rexroth hydraulic pumps:
1. Most users think of a pump as an element that outputs a flow rate at a certain pressure
2. Hydraulic pumps often work at stable and high speeds
3. Generally, it is required that the pump can output high pressure when the rated speed is saved
4. In some applications, the pump is generally only ...

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
(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 ...
