The rules and requirements for the operation of air compressors under load are to ensure the safe and efficient operation of the equipment, as well as to extend its service life. Here are some important rules to follow:

1.Gradually increase the load: After the air compressor is started, the venting valve or oil-water blowing valve should be gradually closed, and the compressor should be operated at 1/4 rated pressure for 1 hour, and then at 1/2 rated pressure for 4-8 hours to ensure that all parts of the equipment can adapt to the gradual increase in pressure.

2. Operation under minimum pressure: After operating under minimum pressure to ensure that there is no abnormal phenomenon, the pressure can be gradually increased to the rated working range.
3. Special requirements for large high-pressure air compressors: For large-scale high-pressure air compressors, the operating time under nominal pressure shall not be less than 24 hours to ensure the stable operation of the equipment under high pressure.

4.Inspection during operation: During operation, it is necessary to regularly check the pressure, temperature and oil supply of the lubricating oil to ensure that the oil pressure is not less than 1 kg/cm², and the temperature of the lubricating oil should be controlled within the specified range.

5.Check the cooling system: check the temperature of the inlet and outlet water and the supply of the cooling water to ensure that the cooling water is smooth and free of bubbles and blockages, and the drainage temperature should not exceed 40°C.

6.Check for leakage: check the connecting flange parts, shaft seals, intake and exhaust valves, cylinder heads and water jackets, etc., to ensure that there is no air leakage, oil leakage and water leakage.

7. Check the moving parts: confirm that the intake and exhaust valves are working normally, the safety valves are sensitive, and there is no loosening of the connecting parts.
8. Check the motor: check the heating and current value of the motor to ensure that it meets the specified requirements.
9. Inspection after operation: including disassembling valves at all levels, checking the mirror friction of the cylinder, checking the friction on the surface of the piston rod, and replacing the lubricating oil in the fuselage.

10.Regular maintenance: Formulate a detailed maintenance plan, implement fixed operation, regular maintenance, and regular inspection and maintenance to keep the air compressor clean and in good condition.

11.Safe operation: Operators should receive professional training to understand the normal operation and maintenance process of the air compressor to ensure safe operation.
Following these rules and requirements can ensure the safety and reliability of the air compressor under load, while also helping to improve its efficiency and service life.
