What is the reason for the failure of the air compressor

Air compressor shutdown failure reason one: the exhaust temperature of the unit is high

1. The lubricating oil level of the machine is low; Solution: Add oil to the 1/2~2/3 position of the sight glass.

2. The cooling fan is not working properly; Solution: Troubleshoot or replace the fan.

3. The temperature sensor does not work; Solution: It is recommended to replace it.

4. The lubricating oil specification is incorrect or deteriorated; Solution: Check the oil number and replace the oil product. The old oil must first be completely drained and injected with new oil.

5. The cooler is blocked and the heat exchange is poor; the solution: check and clean the cooler.

6. The temperature of the computer room is high; Solution: Strengthen indoor ventilation.

7. The oil filter is blocked; solution: remove and replace.

Air compressor shutdown failure reason two: air compressor exhaust temperature is lower than the normal value

1. Temperature control valve failure; Solution: Replace.

2. The oil flow is too large; the solution: reduce the oil control valve flow.

3. The ambient temperature is too low; the solution: reduce the heat dissipation area of the cooler.

4, empty car time is too long; Solution: increase air consumption.

5. Temperature sensor failure; Solution: adjust or replace.

Air compressor shutdown failure reason three: exhaust gas oil content is high, add lubricating oil cycle is short

1. The oil return pipeline is blocked; Solution: Disassembly and cleaning.

2. The pressure can keep the valve spring fatigue; the solution: replace the new spring.

3. The oil level is too high; Solution: Check the oil level and discharge it correctly. The oil level should be 1/2~2/3 of the observation mirror.

4. The exhaust pressure is too low when the air compressor is running; Solution: Set the pressure switch to the set value.

5. The check valve in the return line is damaged; Solution: Replace.

6. The oil and gas separation filter element is damaged and invalid; Solution: Replace.

Air compressor shutdown fault reason four: the starting current of the air compressor is large and tripped

1. The input voltage is too low; Solution: Adjust the input voltage.

2. The wiring is loose; Solution: Check whether there is heat generation and rewiring.

3. The intake valve is opened or stuck; Solution: Regular maintenance and replacement of the intake valve repair kit.

4. The star-triangle conversion time is too short; Solution: Reset the interval time.

5. The problem of starting the air switch; Solution: repair or replace.

6. The main motor or the main motor is faulty; the solution: the belt can be removed or the connection with the motor can be disconnected, and a few laps can be manually started to verify whether the host is suspended or the friction is large.
