Maintenance points of vacuum coating equipment






The vacuum coating equipment must be maintained after long-term operation. The maintenance points are as follows:


If the vacuum coating equipment is used continuously for more than 6 months, the pumping speed of the vacuum coating equipment will be significantly slower. How to maintain it? This article briefly describes the maintenance points of vacuum coating equipment after long-term operation.


First of all, it must be flushed into the atmosphere, the connecting water pipe must be removed, the first-level nozzle must be screwed out, and then the pump cavity and pump gallbladder must be cleaned with gasoline, and then washed with washing powder and water. After the water evaporates, install it. pump, refill the newly diffused pump oil, and put it back into the body, and then it can be restarted.


When the vacuum electroplating is restarted, special attention should be paid to the leak detection work. First, observe whether the vacuum degree of the diffusion pump reaches 6*10PA, otherwise we must conduct leak detection.


Check whether the sealing ring is installed at the joint, or the sealing ring is crushed. It can be heated only after eliminating the hidden danger of air leakage, otherwise the diffusion pump oil will burn the ring and cannot enter the working state.


  When the pump of the vacuum coating equipment works continuously for a month, we must replace the new oil again and completely discharge the old oil in the pump oil. Then add new pump oil to a certain amount. After continuous use for more than half a year, the oil cover should be opened when changing the vacuum pump oil, and the dirt in the box should be wiped off with a cloth.
