First, the hydraulic system failure

1. Insufficient pressure: It may be that the hydraulic tank oil level is insufficient or the hydraulic pump is damaged. The oil level of the hydraulic tank should be checked in time, and the hydraulic pump should be replaced or repaired.

2. The temperature is too high: it may be that the hydraulic oil is too dirty, blocked or the pump flow is too large. Can replace the hydraulic oil, clean the hydraulic oil circuit, adjust the pump flow.

3. The mechanism is not moving or stuck: it may be the inlet and outlet valve is stuck or the sediment or bubbles in the hydraulic cylinder. Can clean inlet and outlet valves or clean hydraulic cylinders.

4. Leakage: the seal may be aging or damaged. Seals can be replaced or hydraulic cylinders repaired.

Second, electrical control failure

1. Electrical control system failure: may be poor contact or open circuit. You can check the terminal and reconnect it.

2. Sensor fault: The signal reception may be abnormal or unable to feedback. You can replace the sensor or check the signal input line.

Third, mechanical transmission failure

1. Mechanical transmission system failure: it may be poor gear mesh or bearing wear. Gears or bearings can be replaced to adjust the transmission structure.

2. Improper operation: It may be caused by improper adjustment or improper use. It can be properly adjusted and used according to the operation manual.

To sum up, the common faults and troubleshooting methods of the hydraulic plate rolling machine need to be analyzed and solved according to the specific situation, and it is recommended that the equipment user have a certain maintenance and maintenance experience in daily operation, and regularly check and repair the equipment to ensure the normal operation of the equipment.

This paper introduces the common faults and troubleshooting methods of hydraulic plate rolling machine, hoping to be helpful to enterprises and individuals using this equipment.
