What is the fault of the air compressor working all the time?

Air compressor has been working continuously may be caused by a variety of faults, the following are some common reasons and corresponding solutions:

common faults and causes

1. leakage of gas path system

   • reason: When there is a leak in the gas circuit system, such as loose gas pipe joints, loose valve seals, etc., the air compressor needs to work continuously to supplement the leaked gas, resulting in failure to stop.

2. Pressure sensor or pressure switch fault

   • reason: The pressure sensor or pressure switch is responsible for monitoring the pressure in the gas circuit. If they fail, the air compressor may not be able to correctly sense that the pressure has reached the set value and continue to pump air.

3. Imbalance or damage of pressure regulating valve

   • reason: The pressure regulating valve is used to control the pressure of the output gas of the air compressor. If the pressure regulating valve is out of adjustment or damaged, the pressure may not be stabilized within the normal range, so that the air compressor continues to work.

4. Relay fault

   • reason: When the pressure sensor or pressure switch has given a signal, but the relay does not perform the power-off operation, the air compressor will continue to run.

5. Intake valve failure

   • reason: If the intake valve cannot be closed normally, the air compressor will continue to inhale gas and work.

6. Unloading valve fault

   • reason: The unloading valve is used to close the air inlet when the air pressure reaches the set value. If the unloading valve is damaged or stuck, the air inlet will not be closed normally, causing the air compressor to continue to work.

7. Oil-gas separator blocked

   • reason: The blockage of the oil and gas separator will affect the normal exhaust of the air compressor, causing the pressure to fail to rise to the set value, so that the air compressor continues to work.

8. Excessive gas consumption

   • reason: When the gas production capacity of the air compressor cannot meet the actual gas demand, the air compressor will always work to try to meet the gas consumption.

9. Air compressor internal failure

   • reason: Such as piston ring wear, cylinder strain, etc., these failures will affect the compression efficiency of the air compressor, making it impossible to reach the set pressure in a short time, so as to continue to work.

Solution measures

1. check and repair the leakage of gas circuit system

   • carefully check the various connecting parts in the gas path, such as gas pipe joints, valves, etc., and repair or replace the seals in time if leakage points are found.

2. Replace pressure sensor or pressure switch

   • if it is confirmed that the pressure sensor or pressure switch is faulty, replace it with a new pressure sensor or pressure switch in time.

3. Adjust or replace the pressure regulating valve

   • readjust the pressure regulating valve to ensure that it can control the pressure normally. If the pressure regulating valve is damaged, it needs to be replaced.

4. Check and repair the relay

   • check the working status of the relay. If the relay is found to be faulty, it should be repaired or replaced in time.

5. Inspect and repair the intake valve

   • check the working status of the intake valve to ensure that it can be closed normally. If the intake valve fails, it should be repaired or replaced in time.

6. Check and repair the unloading valve

   • check the working status of the unloading valve to ensure that it can normally close the air inlet when the air pressure reaches the set value. If the unloading valve fails, it should be repaired or replaced in time.

7. Clean or replace the oil/gas separator.

   • Clean or replace the oil and gas separator regularly to ensure that it is unobstructed.

8. Evaluate and replace larger capacity air compressors

   • if it is confirmed that the air compressor continues to work due to excessive air consumption, it should be evaluated and replaced with a larger capacity air compressor according to actual needs.

9. Disassemble and overhaul the air compressor

   • when it is suspected that the internal failure of the air compressor leads to continuous work, the air compressor should be disassembled and overhauled, and the worn parts, such as piston rings and cylinders, should be replaced.

Preventive measures

1. regular inspection and maintenance

   • regularly check and maintain the air circuit system, pressure sensor, pressure regulating valve, relay, intake valve, unloading valve, oil and gas separator and other components of the air compressor to ensure its normal operation.

2. Use of high quality accessories

   • when replacing accessories, high-quality original or certified accessories should be used to ensure the performance and stability of the equipment.

3. Reasonable setting of working pressure

   • set the working pressure of the air compressor reasonably according to the actual gas demand to avoid unnecessary energy consumption and failure caused by setting too high or too low.

4. Training of operators

   • operators should be trained to understand the working principle and operating specifications of the air compressor to avoid malfunctions caused by improper operation.

Through the implementation of the above measures, we can effectively solve the problem that the air compressor has been working continuously, and prevent the occurrence of similar failures.
