What is the air compressor working continuously?

Air compressor intermittent work may be caused by a variety of reasons, the following are some common reasons and solutions:

common Causes

1. leakage of gas path system

   • reason: If there are leakage points in the gas path, such as loose connection parts such as gas pipe joints and valves or damaged seals, it will cause compressed air leakage, making it difficult for the air compressor to reach the set pressure, thus working continuously.
   • Solution: Carefully check each connection part in the gas path, and repair or replace the seal in time if any leakage point is found.

2. Pressure sensor or pressure switch fault

   • reason: The pressure sensor or pressure switch is responsible for monitoring the pressure in the gas circuit. Once a failure occurs, the air compressor may not be able to correctly sense that the pressure has reached the set value, thus continuously pumping or working continuously.
   • Solution: Check whether the pressure sensor or pressure switch is working normally, if there is any abnormality, it should be replaced or repaired in time.

3. Imbalance of pressure regulating valve

   • reason the pressure regulating valve is used to control the pressure of the air compressor output gas. If the pressure regulating valve is out of adjustment, the pressure cannot be stabilized within the normal range, resulting in the air compressor working continuously or intermittently.
   • Solution: Readjust the pressure regulating valve so that it can control the pressure normally. If the pressure regulating valve is damaged, it needs to be replaced.

4. Oil-gas separator fault

   • reason: The failure of the oil and gas separator will cause a large amount of oil to be mixed into the air, which will affect the normal operation of the air compressor and make it work continuously.
   • Solution: Clean and maintain the oil and gas separator to ensure its normal operation. If the fault is serious, it may be necessary to replace a new oil-gas separator.

5. Air filter element clogged

   • reason: If the air filter element is not cleaned and replaced for a long time, it will be blocked, resulting in insufficient air supply, and the air compressor will work continuously.
   • Solution: Clean and replace the air filter element regularly to ensure its normal smoothness.

6. Solenoid valve fault

   • reason if the solenoid valve is used for a long time, it will be blocked, the coil short circuit or virtual connection, which will affect the air supply, resulting in the air compressor working continuously or intermittently.
   • Solution regularly maintain and clean the solenoid valve to ensure its normal operation. If the solenoid valve is found to be damaged, it should be replaced in time.

7. Unstable gas demand

   • reason when the gas consumption of the gas-using equipment fluctuates greatly, the air compressor may start and stop frequently, showing intermittent work.
   • Solution: Consider increasing the capacity of the gas storage tank or adopting frequency conversion control technology to stabilize the system pressure.

8. Pressure switch set incorrectly

   • reason: If the upper and lower limits of the pressure switch are set too close, the air compressor may start and stop frequently.
   • Solution: Adjust the setting value of the pressure switch and increase the difference between the upper and lower limits.

9. Air compressor internal failure

   • reason: Internal failures such as piston ring wear and cylinder wear will affect the working efficiency of the air compressor, making it unable to reach the set pressure after long-term operation, thus working continuously.
   • Solution: Disassemble and repair the air compressor and replace the worn parts.

Summary

the intermittent operation of the air compressor may be caused by a variety of reasons, including air system leakage, pressure sensor or pressure switch failure, pressure regulating valve imbalance, oil and gas separator failure, air filter blockage, solenoid valve failure, and gas demand. Unstable, improper setting of pressure switch, and internal failure of the air compressor. In view of these reasons, it is necessary to investigate one by one and take corresponding measures to ensure the normal operation of the air compressor. At the same time, regular maintenance of the air compressor is also an important measure to prevent such failures.
