What should I do when the air compressor fails to start?

 

1. Check the power supply. If the power supply is not connected, you can close the power switch to connect the power supply.

 

2. The fuse of the control circuit is blown: the fuse needs to be replaced immediately to find out the cause and solve it.

 

3. The thermal overload relay is disconnected: correct the cause of the overload and reset the thermal overload electrical appliance.

 

4. If the voltage is too low, please ask the power department to check the input voltage and compare it with the motor terminal voltage to check the cause of the low voltage.

 

5. Whether it is a power failure, you need to check the power supply part at this time.

 

6. Is it because the wiring is loose. At this point all wiring terminals should be checked and tightened if any are loose.

7. Temperature sensor failure: You need to check the sensor, if there is a failure, you need to contact professional maintenance personnel for repair.

 

8. Transformer failure: check the secondary voltage of the transformer.

 

9. The thermal overload relay is disconnected: correct the cause of the overload and reset the thermal overload electrical appliance. In order to ensure the normal operation and long service life of the unit, good maintenance is the key. So what preparations do we need to make before maintenance? Carefully implement the maintenance procedures of the screw compressor unit.

Before starting maintenance, prepare at least the following:

 

1. First cut off the power of the host and hang a sign on the power switch.

 

2. Close the shut-off valve leading to the air supply system to prevent the compressed air from flowing back to the part being overhauled. Do not rely on the one-way valve to isolate the air supply system.

 

3. Open the manual vent valve to vent the pressure in the system and keep the vent valve open.

 

4. For water-cooled machines, close the water supply system and release the pressure of the water pipeline.

 

5. Make sure that the compressor unit has cooled down to prevent scalds and burns.

 

6. Wipe off the oil and water marks on the ground to prevent slipping.

Pay attention to these four points during maintenance:

 

1. Don’t think that when the machine is stopped, it can be repaired and maintained. The automatic control system of the machine will start the compressor at any time.

 

2. Poor maintenance will not only affect the normal operation of the unit, but may also affect the safety of operators.

 

3. When the compressor is running or under pressure, do not remove nuts, filler plugs and other parts.

 

4. Do not use flammable solvents, such as gasoline or kerosene, to clean the air filter or other parts.
