Permanent magnet variable frequency air compressor fault

There is a reason for the failure of permanent magnet variable frequency air compressor. When the equipment fails, we must quickly find out the cause of the failure, restore the normal operation of the machine as soon as possible, and reduce the loss of the factory.

Common faults and solutions of permanent magnet variable frequency screw air compressor:

1. air compressor loading fault

1. When the pressure exceeds the rated air pressure, there is no need to take measures to cut off the pressure regulator. When the unit operating pressure is too low, the equipment is automatically loaded.

2. Disassemble and check the solenoid valve failure, and replace it with a new one if necessary.

3. If there is leakage in the pipeline, check the pipeline and joints. If there is leakage, repair is required.

High temperature of 2. unit

1. Check the use of lubricating oil in the unit. If there is no oil or the oil level is too low, it is necessary to add oil in time.

2. Replace the oil filter when the oil filter is blocked.

3. If the oil cut-off valve fails, check that the valve core is stuck.

4. The filter element of the oil and gas separator is blocked or the resistance is too large. Clean and replace it with a new one in time.

5. Check the surface blockage of the oil cooler and clean it if necessary.

3. permanent magnet variable frequency air compressor has high fuel consumption

1. If the oil level is too high, check the oil level and drain the oil to the normal position after pressure relief.

2. Check and replace the oil.

3, the use of inferior lubricating oil.

4. Oil return pipe joint of oil and gas separator filter element is blocked and needs to be cleaned.

4. air compressor host abnormal sound

1. Remove and replace the damaged bearing.

2. Remove and replace the motor and damage the bearing.

3. Low exhaust pressure.

4. Check the connection of the equipment and deal with the leakage in time.

5. Remove the blocked air filter for cleaning or replacement.

6. Disassemble the safety valve for leakage inspection. If it is not sealed and replaced after repair.

7. There is leakage in the control pipeline between the oil-gas separator and the discharge valve.

The above are the common faults and solutions of permanent magnet variable frequency air compressor, for reference only.
