Fault Comparison Table to Confirm The Fault

Time : 2022-02-10 Hits : 55

In case of any abnormal phenomenon during the operation of the air compressor, the cause of the fault must be found out immediately, the fault must be eliminated immediately, and the air compressor can not be used again until it is repaired. Do not continue to use blindly, resulting in unpredictable losses.

Air compressor troubleshooting reference table

1.The air compressor cannot be started

Possible causesElimination methods and Countermeasures
1. Fuse blownAsk electrical personnel to repair and replace
2. Starting electrical fault
3. Poor contact of start button
4. Poor circuit connection
5. The voltage is too low
6. Main motor fault
7. Air end failure (air end has abnormal  sound, local hot)
8. Power phase loss
9. Fan motor overload

2. When the operating current is high, the air compressor will stop automatically (main motor overheating alarm)

1. Voltage too low1. Ask electrical personnel to check
2. Exhaust pressure too high2. Check / adjust pressure parameters
3. Oil gas separator blocked3. Replace with new parts
4. Compressor air end failure4. Disassembly and inspection of engine body
5. Circuit fault5. Ask electrical personnel to check

3. The exhaust temperature is lower than the normal requirements

1. Temperature control valve failure1. Overhaul, clean or replace the valve core
2. Empty load too long2. Increase gas consumption or shutdown
3. Exhaust temperature sensor failure3. Check and replace
4. Compressor air end failure4. Cleaning and replacement

4. If the exhaust temperature is too high, the air compressor will stop automatically (alarm for too high exhaust temperature)

1. Insufficient lubricating oil1. Check and add oil
2. Incorrect specification / model of lubricating oil2. Replace with new oil as required
3. Oil filter blocked3. Check and replace with new parts
4. The oil cooler is blocked or the surface dirt is serious4. Inspection and cleaning
5. Temperature sensor failure5. Replace with new parts
6. Temperature control valve out of control6. Check, clean and replace new parts
7. Excessive ash collection of fan and cooler7. Remove, clean and blow clean
8. Fan motor not running8. Check the circuit and fan motor

5.The oil content of exhaust gas is large

1. Oil gas separator damaged1. Replace with new parts
2. The check return valve is blocked2. Clean the check valve
3. Excessive lubricating oil3. Drain some cooling oil

6. The exhaust volume of the air compressor is lower than the normal requirements

1. Air filter blocked1. Blow out impurities or replace with new parts
2. Oil gas separator blocked2. Replace with new parts
3. Air leakage of solenoid valve3. Clean or replace with new parts
4. Air pipeline element leakage4. Check and repair
5. Belt slipping and looseness5. Replace with new parts and tension belt
6. The intake valve cannot be fully opened6. Clean and replace damaged parts

7. Drain oil from the air filter after shutdown

The check valve spring in the intake valve fails or the check valve sealing ring is damagedReplace damaged components

8.Safety valve action jet

1. The safety valve is used for a long time and the spring is tired1. Replace or reset
2. Oil gas separator blocked2. Replace with new parts
3. Pressure control failure, high working pressure3. Check and reset
