Appliion
The charge pump series products are used in Rexroth oil pumps as a
supporting operation for control and charge pumps in a closed
system
Product functions and features:
1. Provide cooling oil to the system to reduce the temperature of
the system.
2. Maintain the pressure of the main system loop,
3. And provide the operating pressure to the control loop, the
operating pressure of the system is generally designed to be the
same as the replenishing pressure.
4. Replenish oil loss from internal leakage. In order to avoid
damage to the transmission under any driving and braking
conditions, the charge pressure must be set at the specified
pressure.
5. The charge pump is generally a gear pump or an external gear
pump or a cycloid gear fixed pump, which is installed on the main
pump and driven by the main pump's main shaft. The pressure of the
charge pump is limited by the charge relief valve.
6. The standard charge pump is suitable for most pumps. If the
displacement of the charge pump is insufficient, it is necessary to
increase the displacement of the charge pump or install a gear pump
in the auxiliary spline to provide the necessary Extra oil
