How a full range of vacuum coating machine equipment maintenance

Continuous use of more than 12 months for vacuum coating equipment, the inside of the pumping speed will be slow, that is about to do a good job cleaning in a timely manner. First filling the air, down connection pipe, unload electric furnace plate and nozzle. Pump cavity and pump gallbladder points three times cleaning, use gasoline to clean again, first with detergent to clean it again, then clean with clear water thoroughly clean. After being dried, rejoin the pump oil, packed pump, and put back into the body, can restart. Before restarting, attention should be paid to leak detection work. Start the maintain pump, close the door, after a few minutes, observe whether diffusion pump part of the vacuum degree is 6 x10 palmer, otherwise for leak detection. Check whether the connection place o-ring seal, or crush seal ring. Eliminate leakage hidden trouble is heating, or diffusion pump oil will burn ring, unable to enter the working state.
Each completed more than 200 coating procedures for vacuum coating equipment, should be a clean the studio. Multi arc ion plating factory house that swab repeatedly with caustic soda saturated solution vacuum chamber wall, (pay attention to safety can not direct contact with caustic soda solution, so as not to burn) 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 to clean the dirt in the valve, if you need a light coating machine, please contact us, price concessions, service is good.
Thick in the vacuum coating equipment should change new oil pumping work continuously for 30 days. The old oil discharged completely within the pump. Screw bolt playback oil, add new oil to the quantitative.
