To ensure the long-term and efficient operation of the air compressor, regular maintenance and servicing are required. The following are some basic maintenance steps and related source information:

1.Replace the air filter regularly: The internal clearance of the screw air compressor only allows particles within 15u to be filtered out. Regular replacement can prevent particles larger than 15u from entering the machine, avoid shortening the service life of the oil filter element and the oil-gas separation element, and increase the rotor clearance and reduce the compression efficiency.

2.Replace the oil filter on time: The oil filter element should be replaced after the first 500 hours of operation of the new machine, and then replaced every 1500-2000 hours. If the working environment is harsh, the replacement cycle should be shortened, and it is strictly forbidden to use the oil filter element beyond the expiration date.

3.Replace the oil-gas separator on time: Under normal working conditions, the service life of the oil-gas separator is about 3000 hours. When the oil-gas separator expires or the pressure difference between the front and rear exceeds 0.12Mpa, it must be replaced to avoid motor overload and oil-gas separator damage and oil leakage.

4.Coolant replacement: The first coolant replacement is after 500 hours of running-in period for a new machine, and then every 3,000 hours of operation. When used in harsh environments, the replacement cycle should be shortened and it is best to replace the oil filter at the same time.

5.Clean the dust from the cooler at least once a week: clean or replace the air filter, drain the remaining water in the air compressor, refrigerated dryer, precision filter, and gas tank, and check for abnormal bubbling, dripping, and oil leakage, and check whether all operating parameters are within the working range.

6.Check the oil level, exhaust temperature and exhaust pressure daily: Check for any abnormal sounds and check the machine for any abnormal sounds.

7.Regularly check the air intake control valve, minimum pressure valve, electric control box connection line terminal, safety valve, cooling fan: clean and sweep the cooler, and test the reliability of the safety valve.

8.Maintenance procedures: formulate a detailed maintenance plan, implement designated personnel operation, regular maintenance, regular inspection and maintenance, so that the air compressor unit is kept clean, oil-free and dirt-free.

9.Inspection or replacement cycle: According to the use of the air compressor, determine the corresponding inspection or replacement cycle, such as air filter element, intake valve seal, compressor lubricating oil, oil filter, etc.

10.Safety precautions: When performing maintenance, ensure that the pressure in the air compressor system has been released, isolated from other pressure sources, the switch on the main circuit has been disconnected, and safety signs have been made.

By following these maintenance measures, you can ensure the stable operation of the air compressor to the greatest extent, reduce the probability of failure, and extend the service life of the equipment.
