Common faults and troubleshooting methods of air source treatment components

 

Fault 1: 

The pressure relief valve leaks at high pressure, which is manifested as the valve cover vent hole has been leaking


Remedy: 

1. Confirm whether the connection between the inlet and outlet ports is wrong

     

2, confirm whether the outlet pressure is higher than the inlet pressure

    

3. Confirm whether there is any foreign matter in the seal between the valve core and the diaphragm

    

4. Confirm whether the diaphragm is broken


Fault 2: 

Pressure reducing valve cannot increase pressure


Remedy: 

1. Confirm whether the intake pressure is sufficient and whether the pressure gauge is damaged

      

2, confirm whether the pressure regulating screw is stuck

  

Fault 3: 

Pressure reducing valve cannot maintain pressure


Remedy: 

1. Confirm whether there is any foreign matter in the valve core and diaphragm seal

     

2, confirm whether the connection joints and pipelines are leaking


Fault 4: 

insufficient flow


Remedy: 

1. Confirm whether the intake pressure is stable

     

2, confirm whether the filter element or flow path is blocked by foreign matter

 

Fault five: 

the filter cannot filter water


Elimination method: 

The water removal rate of conventional filters is only 50-60%, and the main function of the filter is to filter impurities. If required, it is recommended to install a filter dedicated to water removal at the front of the equipment

  

Fault six: 

the oil mist device does not spray oil mist


Remedy: 

1. Confirm whether the amount of oil is sufficient

     

2, confirm whether the adjusting valve needle is open

      

3. Confirm whether there is a pressure difference (only when the outlet side uses air)
