The air compressor does not pump air (or called "unable to pump air", "insufficient pressure", etc.) may be caused by a variety of reasons. Here are some common causes and their corresponding solutions:
1. electrical problems
- power supply line or power switch is damaged:
- solution: Check the power supply circuit and power switch, and replace it in time if it is damaged.
- Motor winding burned or short circuit:
- solution: check the motor winding, if there is a short circuit should be repaired in time.
- Electrical component failure: If the capacitor, controller, etc. fails, it may also cause the air compressor to fail to operate normally.
- Solution: Check whether the electrical components are normal, if there is a fault, repair or replace it.
2. mechanical problems
- the internal screw of the air compressor is stuck or the bearing is damaged.:
- solution: Check the internal screw and bearing of the air compressor. If it is stuck or damaged, replace it in time.
- Check valve failure: The one-way valve is an important component to ensure the normal operation of the air compressor. If it fails, it will cause the high-pressure air to flow back and affect the compression effect.
- Solution: remove the check valve for disintegration inspection, repair or replace damaged parts.
- Low pressure check valve failure: When the internal pressure of the machine is very high but there is no pressure output, it may be a failure of the low pressure check valve.
- Solution: replace the less pressure check valve.
- Air compressor server failure: such as yin and yang motor rotor damage, air compressor grease emulsification, etc.
- Solution: contact manufacturers or professional maintenance personnel for inspection and maintenance.
3. lubrication and cooling problems
- insufficient or excessive lubricating oil:
- solution: check the amount of lubricating oil, insufficient should add enough lubricating oil, too much should be adjusted to the appropriate amount.
- Cooling system fault: If the radiator is blocked, the cooling oil level is too low, the oil grade is low or the quality is poor, etc.
- Solution: check and clean the radiator, supplement or replace the cooling oil, use the standard oil.
4. Other Frequently Asked Questions
- air filter clogged:
- solution: Replace the air filter regularly to ensure smooth air circulation.
- Oil filter clogging:
- solution: replace the clogged oil filter.
- Exhaust pipe blocked: The air compressor used for a long time may cause the exhaust pipe to be blocked due to carbon deposits and other reasons.
- Solution: remove the exhaust pipe for cleaning.
- Damaged or aged seals:
- solution: Check and replace the damaged seal.
- Pressure setting incorrect:
- solution: Check and adjust the pressure setting of the air compressor to the correct value.
5. comprehensive inspection and maintenance
regular inspection and maintenance regularly carry out comprehensive inspection and maintenance of the air compressor, including electrical system, mechanical parts, lubrication and cooling system, etc., to ensure its normal operation.
Professional maintenance: If you encounter complex faults or unsolvable problems, you should contact professional maintenance personnel for inspection and maintenance in time.
In summary, the reasons for the air compressor not pumping may involve electrical, mechanical, lubrication and cooling and other aspects. In troubleshooting, should be a systematic and comprehensive inspection of each possible point of failure, and take appropriate solutions to deal.
