What is the reason for the slow pressure on the screw air compressor

Screw air compressor pressure slow (slow boost) may be caused by a variety of reasons, the following is a detailed summary of these reasons and the corresponding solutions:

1. air intake system problem

1. air filter element clogged
   • cause: the air filter is too dirty or blocked will seriously limit the inflow of air, resulting in the screw air compressor on the air speed slower.
   • Solution: Replace or clean the air filter regularly to maintain the stability of the air flow.
2. Intake valve failure
   • reason: The intake valve cannot be fully opened or the action is not good, which will affect the air intake, resulting in slow upward pressure.
   • Solution: Check and replace the intake valve to ensure its normal operation.

2. compression system problems

1. air valve blocked
   • reason: air compressor valve blockage will affect the air flow, resulting in slow boost speed.
   • Solution: Clean or replace the air valve regularly to keep the air flow stable.
2. Yin-Yang rotor wear
   • reason: When there is great wear between the yin and yang rotors and between the inner cavity of the stator, the internal leakage of the air compressor will increase, resulting in loading without pumping.
   • Solution: Contact the manufacturer to detect, repair or replace the worn rotor.

3. oil system problems

1. oil blockage or damage
   • cause: Oil system failure, such as oil blockage or damage, will lead to poor oil circulation inside the air compressor, affecting the generation and discharge of compressed air.
   • Solution: check and repair the oil system in time to ensure that the oil filter is clean and intact.
2. Insufficient quantity or poor quality of lubricating oil
   • reason: Insufficient amount of lubricating oil or poor quality will affect the compression efficiency and sealing performance of the air compressor.
   • Solution: Check the amount of lubricating oil, add or replace high-quality lubricating oil in time.

4. exhaust system problems

1. minimum pressure valve failure
   • cause: The minimum pressure valve setting value is too high or malfunction will limit the air discharge, resulting in a slower air speed.
   • Solution: Set the value of the minimum pressure valve reasonably and check its working condition regularly.
2. Pipeline leakage
   • cause: Air pipe connection is not tight, aging or damage will lead to air leakage, so that the pressure can not increase rapidly.
   • Solution: check whether the pipeline connection is tight, whether there is aging, damage, timely repair or replace the leaking pipeline.

5. other system issues

1. temperature control valve fault
   • reason: The failure of the temperature control valve will affect the cooling effect of the lubricating oil, and then affect the compression efficiency and sealing performance of the air compressor.
   • Solution: repair or replace the temperature control valve to ensure its normal operation.
2. Electrical control system fault
   • cause: The failure of the electrical control system may cause the air compressor to fail to operate or load normally.
   • Solution: Check the electrical control system, troubleshoot, and ensure the normal loading and operation of the air compressor.

In summary, the reasons for the slow pressure on the screw air compressor may involve multiple aspects such as the intake system, compression system, oil system, exhaust system, and other systems. In order to maintain the normal operation of the air compressor and improve work efficiency, users should regularly inspect and maintain these components to find and solve problems in time.
