What is the screw air compressor not pumping

Screw air compressor does not pump may be caused by a variety of reasons, the following are some common reasons and their solutions:

1. intake system fault

1. air inlet blocked:
   • reason: The air compressor working environment is harsh, and foreign matter may be blocked or sucked into the air inlet, resulting in a reduction in air intake.
   • Solution: Check and clean the air inlet to ensure smooth air circulation.
2. Dirty and clogged air filter:
   • reason: The air filter element is too dirty, resulting in increased air intake resistance and reduced air intake.
   • Solution: Clean or replace the air filter element.
3. Intake valve failure:
   • reason: mechanical failure of the intake valve, stuck or unable to open, resulting in insufficient suction volume of the compressor or no air can be sucked.
   • Solution: Check and repair or replace the intake valve to ensure that it is normally opened and closed.
4. Intake solenoid valve fault:
   • reason: intake solenoid valve without power supply, coil burned or loose joints, resulting in the intake valve can not be opened.
   • Solution: check the power supply and wiring of the solenoid valve, repair or replace the faulty solenoid valve.

Internal fault of 2. compressor

1. yin-Yang screw rotor excessive wear:
   • reason: The long-term operation of the compressor causes excessive wear of the yin and yang screw rotors and internal leakage.
   • Solution: Replace the worn screw rotor and check the wear of other related parts.
2. Host Failure:
   • reason: internal failure of the host, such as bearing damage, seal failure, etc.
   • Solution: find professional maintenance personnel to check and repair the host, if necessary, replace the damaged parts.

3. pipeline leakage

1. gas pipeline leakage:
   • cause: There is a leak in the gas pipeline, resulting in the loss of compressed air during transportation.
   • Solution: Check and repair the leaking pipeline to ensure that the pipeline is well sealed.

4. system control fault

1. PLC output point fault:
   • reason: PLC output point failure, resulting in no signal to the solenoid valve, the intake machine does not operate.
   • Solution: let professional maintenance master repair PLC, ensure its normal output signal.
2. Minimum pressure check valve failure:
   • cause: the minimum pressure check valve failure, resulting in the internal pressure can not be output.
   • Solution: replace the fault of the minimum pressure check valve.

5. other factors

1. insufficient air supply:
   • reason: The valve at the air inlet of the air compressor is not opened or the air inlet pipe is blocked.
   • Solution: check and open the intake valve, clean the intake pipe.
2. Too much air consumption:
   • reason: The actual gas consumption is greater than the output gas of the unit.
   • Solution: Coordinate the relationship between air intake and use to ensure that air consumption is maintained within a stable range.
3. Daily maintenance is not in place:
   • reason: The long-term lack of maintenance of the air compressor has led to increased wear and tear of various components and reduced performance.
   • Solution: Regularly maintain the air compressor, check and replace the worn parts.

To sum up, the failure of the screw air compressor may be caused by a variety of reasons, which need to be investigated and solved according to the specific situation. If it cannot be solved by itself, it is recommended to contact professional maintenance personnel for maintenance in time.
