Oil Diffusion Pump Fault Treatment
(Created originally by Foxin Vacuum, please indicate source if reprint.)
The cooling water must be circulated during the operation of the diffusion pump. We can only stop the cooling water cycle until the pump oil is completely cooled
When the pump is not working, we should keep the pump body in a vacuum to ensure that the air pumped by the oil is dry, non-corrosive and dust-free.
Keep the pump under vacuum to protect the pump oil and pump components from corrosion. And clean all the water in the cooling water jacket. Keep room temperature at 10-40 ° C.
If the pump suddenly goes bad, we should check the heater first. It is worth mentioning that the pump is checked regularly.
a. If the pump oil is reduced or oxidized, add oil or replace the oil accordingly.
b. The pump body and the collapsed part should be cleaned with aviation gasoline, then wiped with a wire cloth with ether or acetone on it, and finally dried at 80-100 ° C or dried with a hairdryer.
c. Install all parts step by step, hold the pump core and pump base vertically and maintain the same core as the pump chamber
