1. Under normal circumstances, we need to maintain vacuum coating machine is mainly in terms of vacuum leak detection, vacuum instrument maintenance, demolition and installation to maintenance, we, the inspection step down step by step, it should be able to find the problem, when these still can not solve your machine failures, we need to turn off the power to let the machine rest, work, because the expertise to repair the vacuum coating machine is from the touch screen repair, programming, program decrypt, modify, alter and vacuum coating equipment several aspects of vacuum pump repair, vacuum heat treatment equipment maintenance and other aspects!
2. When the vacuum coating machines (vacuum coating equipment) roughing pump (plunger pumps, rotary vane pumps) continuous month (rainy season halved), to be replaced with new oil. The old oil pump is completely discharged. Tighten bolts playback oil, add new oil to the rated capacity (oil sight glass observation). More than six months of continuous use, the oil change the oil when the cover is opened, the box with a cloth to wipe clean the dirt.
Vacuum coating equipment for each completed more than 200 film programs, clean studio once. With caustic soda (NaOH) solution saturated repeated scrubbing vacuum chamber wall, (note can not directly contact with human skin caustic soda solution, in order to avoid burns) are intended to make up coating material coated aluminum (AL) react with NaOH, after the reaction the film off, and release hydrogen, then rinse with a cloth dipped in a vacuum chamber and pumping gasoline to clean fine dirt inside the valve.
Vacuum coating equipment diffusion pump continuously for 6 months or more, the pumping speed will be significantly slower, or operating properly, filling the air, remove the link pipe, remove the electric drive, will be screwed out of a nozzle, first with gasoline the pump chamber and pump bile clean again, and then wash detergent watered again, then rinse thoroughly with clean water, after water evaporation until dry, install the pump bulb, adding a new diffusion pump oil, and replace the body, take a good pipes, installed electric drive, they can re-boot. Before rebooting, pay attention to leak job. Start maintain pump, shut the door, after a few minutes to observe whether the diffusion part of the pump vacuum reaches 6X10 Pa, or to check for leaks. Check that the connection of the installed gasket, seals or crushed. After eliminating hidden leaks before heating, otherwise diffusion pump oil will burn ring, unable to enter the working state.
