Air compressor normal maintenance need to replace what

The main components that need to be replaced for normal maintenance of the air compressor include air filter element, oil filter, oil and gas separator, rotor lubricating oil and some other wearing parts and consumables. The following is based on different sources and authoritative information to organize the specific content:

1. air filter element

• role filter dust and particles in the air to ensure that the air entering the air compressor is clean.

• Replacement cycle:

  • maintain once a week and blow off the dust on the outer surface with compressed air.
  • Under normal circumstances, the air filter element should be replaced every 1000-1500 hours, and it is recommended to replace it every 500 hours in extremely harsh environments such as mines, ceramic factories, and cotton mills.
  • The new machine should also be replaced after 500 hours of first operation.

2. oil filter

• role: Filter the impurity particles in the lubricating oil to keep the lubricating oil clean.

• Replacement cycle:

  • the new machine must be replaced after 300-500 hours of first operation.
  • The second one was replaced at 2000 hours and then every 2000 hours.
  • When the environment is bad, the replacement cycle should be shortened.
  • Replace the oil filter with each oil change.

3. oil-gas separator

• role: Separate the oil and gas mixture in the oil and gas barrel into oil and air to reduce the oil content in the air.

• Replacement cycle:

  • under normal operation, the service life of the oil and gas separator is about 2000 hours, but the quality of the lubricating oil and the filtration accuracy of the air have a great impact on its service life.
  • The maintenance and replacement cycle of the air filter element must be shortened in the harsh use environment.
  • When the service life of the oil-gas separator has reached, or the pressure difference between the two ends of the separator exceeds 0.12Mpa, it must be replaced.

4. rotor lubricating oil

• role: Circulating in the air compressor to play the role of cooling, lubrication and sealing.

• Replacement cycle:

  • replace the new oil after 500 hours of operation for the first time.
  • After that, it should be replaced every 4000 hours. Machines with less than 4000 hours of annual operation should be replaced every year.

5. other wearing parts and consumables

• belts and drive components: Regularly check the tightness and wear of the belt, and adjust or replace it as needed. Transmission parts need to check the condition of lubricating oil, and timely add or replace.
• Coolers and radiators: Regularly clean the dust and dirt on the cooler and radiator to improve the heat dissipation effect and avoid overheating and machine failure.
• Vortex separator: Regularly remove the water and oil in the vortex separator to keep it working normally.
• Safety valve, pressure gauge and other protective devices regularly check to ensure normal function and eliminate hidden trouble.

6. maintenance precautions

• when replacing the filter element, oil filter and other components, ensure correct operation to prevent debris from falling into the air compressor.
• Before maintenance, adjust the parameters of the air compressor and check the internal parts of the machine to ensure that there is no oil leakage.
• After the maintenance is completed, the machine should be started to check the operation and ensure that everything is normal before it is put into use.
• Maintenance records should be detailed records of maintenance date, maintenance content, replacement parts and other information, in order to develop a more scientific and reasonable maintenance plan.

In summary, the main components that need to be replaced for normal maintenance of the air compressor include the air filter element, oil filter, oil and gas separator and rotor lubricating oil. In addition, it is necessary to regularly check and replace other wearing parts and consumables according to the specific situation, and pay attention to the details and precautions in the maintenance process.
