The maintenance of hydraulic press in automobile production needs to pay attention to the following matters:

1. Check the hydraulic oil regularly-ensure the cleanliness of the hydraulic oil, take samples and test it regularly, and replace it in time if the oil is seriously polluted.

-Check the oil level, keep it within the specified range, and replenish it in time when it is insufficient.

-Pay attention to the temperature of hydraulic oil to avoid the oil temperature being too high or too low. Generally, the appropriate temperature is between 30-55℃.

2. Cleaning and filtration system

-Regularly clean the impurities and deposits in the fuel tank.

-Check and replace the hydraulic oil filter to ensure the filtering effect.

3. Fasten the connector

-Regularly check the bolts, nuts and other connectors of various parts of the hydraulic press to ensure that the fastening is not loose.

4. Check the seal

-Observe whether the seals are worn, aged and leaked, and replace the damaged seals in time.

Step 5 lubricate parts

-Regularly lubricate moving parts, such as slider guide rails and columns, to reduce wear and tear.

6. Electrical system maintenance

-Check the electrical wiring for damage and aging, and ensure the normal operation of electrical components.

-Clean the dust in the electrical control cabinet to prevent short circuit and fault.

7. Safety valve and pressure relay

-Regularly check the safety valve to ensure that it works normally under the set pressure.

-Check the set value and working state of the pressure relay.

8. Cooling system

-Check the working condition of the cooling system to ensure that the oil temperature can be effectively controlled.

9. Mold maintenance

-The mould should be cleaned, rustproof and properly stored after use.

10. Equipment operation monitoring

-Record the operating parameters of the equipment, such as pressure, stroke, speed, etc., so as to find the abnormality in time.

11. Training and operation specifications

-Train operators to ensure that they use the equipment in strict accordance with the operating procedures.

12. Regular comprehensive maintenance

-Make regular comprehensive overhaul plans and conduct comprehensive inspection and maintenance of equipment.

13. Reserve of spare parts

-Reserve some commonly used vulnerable parts for timely replacement and reduce downtime.
