The air compressor may encounter various common problems during operation. The following is a detailed summary and explanation of these problems:

1、 Start failed

Possible causes: power supply issues, motor malfunctions, or control system issues.

Solution:

Check if the power sockets, switches, and cables are intact and undamaged to ensure a stable power supply.

Test the continuity and insulation of the motor, and check if the contactors and relays of the starter are working properly.

Check if there are any faults in the control panel and related circuits.

2、 Insufficient pressure

Possible causes: system leakage, decreased compression efficiency, or filter blockage.

Solution:

Use soapy water or a specialized leak detector to check for leaks in pipeline connections, valves, and joints.

Check the intake filter and oil gas separator, and clean or replace them if necessary.

Check the piston, ring, and cylinder for wear to ensure compression efficiency.

3、 Overheating

Possible causes: cooling system malfunction, improper maintenance, low oil level, low oil grade or poor oil quality, broken or loose fan tape, faulty oil cut-off valve, etc.

Solution:

Clean the cooler, check the operation status of the cooling fan and water pump, and ensure that the cooling system is functioning properly.

Adjust the load to avoid prolonged full load operation.

Check and replenish lubricating oil to ensure that the oil level is normal.

Use compressor oil recommended by the manufacturer and avoid using low-grade or inferior oil.

Check and replace the fan tape to ensure proper tightness.

Check and repair the oil cut-off valve to ensure its normal operation.

4、 Abnormal noise

Possible causes: bearing damage, insufficient lubrication, loose components, belt slipping, dry metal friction, etc.

Solution:

Check the bearings and lubrication system to ensure that the bearings are free of wear and well lubricated.

Tighten loose parts, such as screws, bolts, and mechanical components.

Check and replace the belt to ensure proper tension.

Check the oil supply of the air compressor to ensure that there is no dry metal friction.

5、 Oil water separator malfunction

Possible cause: The oil-water separator is not working properly, affecting air quality.

Solution:

Regularly check the working status of the oil-water separator, clean or replace the separation components.

Regularly discharge condensate from the oil-water separator to avoid water backflow.

6、 Corrosion and fracture faults

This type of failure mainly involves metal corrosion and mechanical fracture, which may be caused by various reasons, such as chemical corrosion, electrochemical corrosion, physical corrosion, mechanical fatigue fracture, thermal fatigue fracture, and plastic fracture.

Solution:

Regularly inspect the corrosion of various components of the air compressor and replace severely corroded components in a timely manner.

Regularly inspect the mechanical components of the air compressor, such as connecting rods, bolts, etc., to ensure that there is no fatigue fracture phenomenon.

7、 Exhaust temperature too high

Possible causes: mechanical malfunctions, lubricating oil issues, etc.

Solution:

Inspect and repair relevant mechanical components, such as oil stop valves, compressor oil filters, etc.

Check and replace the lubricating oil to ensure its quality and oil level are normal.

8、 Abnormal cooling fan

Possible causes: Fan damage, motor malfunction, etc.

Solution:

Check and replace the cooling fan to ensure its normal operation.

Check the fan motor to ensure there are no faults.

9、 Insufficient oil quantity

Possible reasons: low oil level, leakage, etc.

Solution:

Add an appropriate amount of lubricating oil in a timely manner to ensure the oil level is normal.

Check and repair the leakage point to prevent further reduction in oil volume.

The above is a summary and solution of common problems with air compressors, hoping to be helpful for your air compressor maintenance and troubleshooting work.
