Reasons for unloading of single column hydraulic press

- 02/09/2024 -

In the work of the hydraulic system, sometimes the actuator stops working for a short time, or the actuator maintains a certain force during a certain period of working time, but moves very slowly or even stops moving. In this case, there is no need to consume the power of the hydraulic system. For this reason, an unloading circuit is needed, that is, when the hydraulic pump driving motor does not open and close frequently, the hydraulic pump can operate with the power output close to zero. , to reduce power loss, reduce system heat, and extend the life of the pump and motor.
