Optional vacuum pump for coating machine parts

For the vacuum coating machine, the vacuum pump is an indispensable component of the vacuum environment, and the manufacturer manufactures one coating machine with one or more vacuum pumps.

First, when selecting a vacuum pump, first of all, it is necessary to pay attention to whether the vibration generated by the vacuum pump has an influence on the process and the environment. If the process is affected, anti-vibration measures or an alternative vacuum pump should be adopted. When selecting, you need to know the composition of the gas to be pumped. If you need selective pumping, a pump may not be enough to meet the requirements. You must combine a variety of different pumps to work together. If the coating machine requires oil-free coating, you should use it. Oil-free pump.

Second, the coating machine's limit requirements on vacuum and working pressure requirements are greater. The vacuum pumping capacity of the vacuum pump is higher. The ultimate vacuum of the minimum pump is higher than half the order of vacuum of the vacuum equipment.

Third, each pump has a certain working pressure range, such as the pressure of the diffusion pump is 3~10-7mmHg, and its stable working pressure range is 5*10-4~5*10-6mmHg, then the diffusion pump can not be used. It works outside the range of undetermined working pressure.

4. When the gas pressure required by the pump is not high or the required vacuum is not high, it can be selected firstly in the single-stage pump. The requirements for passing the exhaust pressure or the vacuum are high. The single-machine pump often cannot meet the requirements. Two-stage pump or multi-stage pump.

Fifth, the price of vacuum pumps and maintenance costs are also one of the priorities to consider.
