What’s going on when the air compressor works intermittently

The air compressor intermittent and continuous operation may be caused by a variety of reasons. The following are some common reasons and corresponding solutions:

1. Common reasons

  1. Pressure switch fails

    • After the air compressor is started, the start and stop of the air compressor is usually automatically controlled through the pressure switch. When the pressure switch fails, the air compressor may not correctly sense the pressure changes in the pipe, resulting in interrupted and continuous operation.
  2. Gas system leakage

    • If there is a leak point in the gas circuit, the air compressor needs to continue working to replenish the leaked gas, thereby keeping the pressure in the pipeline stable. This will cause the air compressor to work intermittently.
  3. Pressure sensor or pressure automatic switch fails

    • Pressure sensor or pressure automatic switch is responsible for monitoring the pressure in the air circuit. Once a failure occurs, the pressure changes may not be accurately sensed, causing the air compressor to continue working.
  4. Oil and gas separator failure

    • The function of the oil and gas separator is to separate oil and gas in compressed air. If the oil and gas separator fails, it will cause a large amount of oil to be mixed into the air, which will affect the normal operation of the air compressor, which may cause it to work continuously.
  5. The air filter element is blocked

    • If the air filter element is not cleaned and replaced for a long time, it will cause blockage, resulting in insufficient air supply. In order to maintain normal pressure output, the air compressor may operate intermittently.
  6. Solvent valve is blocked

    • If the solenoid valve is used for a long time, it may become blocked, affecting the supply of air, resulting in the air compressor being continuously working.
  7. The gas demand is unstable or increased

    • When the gas consumption of the gas equipment fluctuates greatly or increases, the air compressor may need to start and stop frequently or continue to work to meet the gas demand.
  8. Pressure regulating valve is imbalanced

    • Pressure regulating valve is used to control the pressure of the air compressor’s output gas. If the pressure regulator valve is not adjusted, the pressure cannot be stabilized within the normal range, which may cause the air compressor to continue to work.
  9. Head head failure

    • The head of the machine is the core component of the air compressor and is responsible for absorbing air and generating pressure. If the head is aging or malfunctioning, it will directly affect the normal operation of the air compressor, which may cause it to work continuously.

2. Solution

  1. Check and replace the pressure switch

    • If the pressure switch fails, check and replace the new pressure switch in time to ensure that the air compressor can correctly sense the pressure changes in the pipeline.
  2. Inspect and repair leaks in the gas circuit system

    • Cleanly check all connection parts in the gas circuit, such as tracheal joints, valves, etc., and repair or replace the seals in time when the leakage points are found.
  3. Check and replace the pressure sensor or pressure automatic switch

    • If the pressure sensor or pressure automatic switch fails, a new sensor or switch should be replaced in time to ensure the accuracy of pressure monitoring.
  4. Cleaning or replacing the oil and gas separator

    • Cleaning and maintenance of the oil and gas separator to ensure its normal operation. If the oil and gas separator is seriously damaged, a new oil and gas separator should be replaced in time.
  5. Cleaning or replacing the air filter

    • Cleaning or replacing the air filter regularly to ensure normal and smooth flow. It is recommended to formulate appropriate cleaning and replacement cycles based on the use environment and the degree of contamination of the filter element.
  6. Cleaning solenoid valves

    • Remain maintenance and cleaning of the solenoid valves regularly to ensure their normal operation. If the solenoid valve is seriously damaged, a new solenoid valve should be replaced in time.
  7. Evaluate and adjust gas demand

    • If the gas demand is unstable or increased, consider increasing the capacity of the gas tank or using frequency conversion control technology to stabilize system pressure and meet gas demand.
  8. Adjust or replace the pressure regulator valve

    • If the pressure regulator valve is not adjusted, the pressure regulator should be readjusted so that it can control the pressure normally. If the pressure regulating valve is seriously damaged, a new pressure regulating valve should be replaced in time.
  9. Check and replace the head>

    • If the head is aging or malfunctioning, check and replace the new head in time to ensure the normal operation of the air compressor.

In summary, the continuous operation of the air compressor may be caused by a variety of reasons. When solving problems, it is necessary to check them one by one according to the specific situation and take corresponding solutions. At the same time, regular maintenance of the air compressor can effectively reduce the occurrence of such failures.
