Analysis of hydraulic system failure of four-column hydraulic press and its solutions.
The hydraulic pump of a four-column hydraulic press is the heart of the hydraulic system, and its operating status will directly affect the work of the entire system. When the plunger pump fails, the outlet pressure signal of the pump must be abnormal, so the pressure signal can be used to detect the state of the hydraulic pump. Pressure sensor at the overflow valve: In the hydraulic system, the overflow valve sets the rating of the hydraulic actuator The working pressure ensures the normal operation of the system and directly affects the working performance and safety of the entire hydraulic system.
The hydraulic pump outlet pressure signal: The hydraulic pump is the heart of the hydraulic system, and its operating status will directly affect the work of the entire system. When the plunger pump fails, the output pressure signal of the pump must be abnormal. Therefore, the pressure signal can be used to check the status of the hydraulic pump. The regular maintenance methods of the hydraulic machine include: regularly test the performance of the servo valve and check the zero correction current of the servo valve Whether it is out of tolerance, replace it in time if there is a fault; replace the faulty servo valve, and return the valve to the servo valve testing center for repair, because the production site does not have the conditions for repairing this valve.
Precautions for the storage and transfer of working oil: Oil drums should be marked and covered. In winter, be careful not to mix the oil into the barrel due to the air condensing into moisture, and do not drop the rusty rust on the barrel skin into the barrel.
