1. The main and mini antechamber cannot replenish air

Reason: The air holes in the glove box leading to the main and mini antechamber may be blocked by plastic film, etc.; Whether the solenoid valve is not opened.

 

Method: Confirm the position of the air hole according to the direction of the pipeline, and clear the pipeline; Check the wiring and solenoid valve.

 

2. The main and mini antechamber cannot be pumped

 

Reasons: The air extraction holes in the main and mini antechamber are blocked by plastic film, etc. or the chamber door leaks; The antechamber door is not closed tightly, or the sealing ring of the main and mini antechamber is loose.

 

Method: According to the direction of the pipeline, confirm the position of the air hole and dredge the pipeline; Close the antechamber door and check the size of the sealing ring; Check whether the operating air pressure is too low (because the main antechamber air valve is a pneumatic valve).

 

3. The tank pressure continues to increase during cleaning

 

Reason: The cleaning valve is not opened, the intake pressure is too high, and the pipeline is not dredged.

 

Method: Ensure that the pipeline is unblocked, preferably not to be bent; When cleaning, the relative pressure in the tank will continue to be lower than 0.5 mbar.

 

4. The main valve of the purification column is defective

 

Reason: The working gas pressure is less than 0.5Mpa; The main valve signal feedback is faulty.

 

Method: Replace the working gas cylinder, or check the pressure of the auxiliary gauge of the pressure reducing valve at 0.5Mpa; Check the signal switch of the main valve.

 

5. The loop cannot be opened

 

Reason: low pressure or high pressure maintenance of the fan inverter.

 


Method: After the voltage is stable, shut down and restart after 1 minute.
