How to maintain the vacuum coating equipment


Vacuum coating equipment uninterrupted use for more than 12 months, inside the pumping speed will 

become slow, this is timely to do the cleaning work, so how to vacuum coating equipment for full maintenance?


First fill into the atmosphere, remove the connection water pipe, discharge the electric furnace plate and nozzle, pump chamber and pump bladder three times cleaning, first with gasoline will be cleaned once, then with washing powder to clean again, and then with water thoroughly clean.


Wait until the sun dried, rejoin the pump oil, installed pump bile, and installed back to the body, you can restart. Pay attention to leak detection before restarting the machine. Start the maintenance pump and close the door. After a few minutes, observe whether the partial vacuum of the diffusion pump reaches 6X10 pa. Otherwise, leak detection should be carried out. Check whether the joint is fitted with sealing ring, or the sealing ring is crushed. Remove the potential gas leakage before heating, otherwise the diffusion pump oil will burn the ring, unable to enter the working state.


Each completed more than two hundred coating process for vacuum coating equipment, should clean workshop, swab repeatedly with caustic soda saturated solution coating equipment manufacturers shows that vacuum chamber wall, pay attention to safety can not direct contact with caustic soda solution, in order to avoid burns, the purpose is to make up the membrane material plating aluminum react with caustic soda, membrane layer falls off after reaction, and release hydrogen, reoccupy clear water clean vacuum chamber and a cloth stained with gasoline cleaning the dirt in the valve.
