When the winding pvd coating machine is in use, it is inevitable that the winding pvd coating machine will be stained with other pollutants due to the problem of use. Therefore, frequent cleaning of the winding vacuum coating equipment has also become an important part of maintaining the machine. Before the equipment is coated with the coating material, a simple surface cleaning of the coating material can prolong the service life of the coating machine, because various contaminants not only make the vacuum system unable to obtain the required vacuum degree, but also affect the strength and sealing of the vacuum parts connection. performance.

Generally in use, the common pollutants of winding pvd coating machine are:
       1. Grease includes lubricants, cutting fluids, vacuum greases, etc. that are contaminated during processing, assembly, and operation;
       2. Hand sweat during operation, water vapor and saliva when blowing air, etc.; residual substances, hand sweat, minerals in water, etc. when cleaning acids, alkalis, and salts; and polishing residues and ambient air. Dust and other organic matter.
Cleaning these contaminants can improve the working stability of the winding vacuum coating equipment, so that the work can be carried out more smoothly.

Tianyong pvd coating machine maintenance problems
       Among all the parts of the winding pvd coating machine, if the diffusion pump is used continuously for more than 6 months, the pumping speed will be obviously slowed down, or the operation will be improper, and it will be charged into the atmosphere. The maintenance method is: remove the connecting water pipe, remove the electric hob, unscrew the first-level nozzle, first clean the pump cavity and pump gallbladder with gasoline, then clean it with washing powder mixed with water, and then thoroughly clean it with water. After the water has evaporated and dried, install the pump tube, add new diffusion pump oil, put it back into the body, connect the water pipe, and install the electric hob, and then you can restart the machine. Before restarting, pay attention to leak detection. Start the maintenance pump, close the door, and after a few minutes, observe whether the vacuum degree of the diffusion pump reaches 6X10 Pa, otherwise it is necessary to check the leak. Check whether the sealing ring is installed at the joint, or the sealing ring is crushed. Heating can only be done after eliminating the hidden danger of air leakage, otherwise the diffusion pump oil will burn the ring and cannot enter the working state.
