1. The principle of Rexroth hydraulic pump oil volume adjustment
Generally, in order to adapt to the specific requirements of the diesel engine under the load, the fuel injection pump must be able to adjust the maximum fuel supply of the whole machine within the range of zero oil supply. The adjustment of the oil supply must be achieved through the tooth rod and the rotating sleeve, so that all the plungers used on the fuel injection pump can be rotated at the same time.
When the column is rotated during the work, the oil supply time will not change, and if the oil supply time is gone, the hypotenuse of the plunger will change due to the change of the position of the various oil return holes in the plunger sleeve. If the angle of rotation of the plunger is different, the effective stroke of the plunger will also change, and the amount of oil supply will also change.
Second, Rexroth hydraulic pump oil volume adjustment method
There are no more than two ways to regulate the flow of the pump, one is to add a speed regulating valve at the outlet of the pump to adjust the flow output, this method is relatively stupid, and the energy loss is not small. The other option is to switch to variable displacement pumps, which can change the flow output by adjusting the angle of the hydraulic pump with hydraulic or electromagnetic force or by hand, which saves energy and lays the foundation for possible automated control.

Precautions for Rexroth pressure reducing valves
1. For easy operation and maintenance, the valve is generally installed upright on the horizontal pipeline.
2. The installation of the pressure reducing valve must be in strict accordance with the direction of the arrow on the valve body and keep it consistent with the direction of fluid flow. If the water quality is not clean and contains some impurities, it must be installed at the upstream inlet of the pressure reducing valve ...

Rexroth hydraulic pump - piston pump selection precautions
1. Determine the pressure
The rated pressure of the selected metering pump is slightly higher than the actual maximum pressure required, generally 10-20% higher. Don't choose too high, too much pressure will waste energy, increase the investment and operating costs of the equipment.
2. Determine the flow rate
Selected ...

Rexroth hydraulic pump - common faults and treatment methods of piston pumps
1. The output flow of the hydraulic pump is insufficient or does not output oil
Piston pumps often suffer from insufficient suction, excessive leakage, or too small an inclination angle. The insufficient suction volume is mainly caused by the high resistance of the suction pipe or the insufficient oil replenishment, such as the pump speed is too fast and the oil level is too low; Excessive leakage ...
