The pressure of the vacuum coating machine control system

 

 Now most of the items needed for surface treatment will be used in the vacuum coating equipment for processing, because this surface processing machinery is not only make rough surface with smooth surface, and general also has the improving effect of the surface gloss. So, not only on the surface of the coating also played a role in surface protection, though not as strong, but to prevent surface erosion. When it comes to such machinery, at present because it is processed in a relatively vacuum environment, so the influence factors of the outside world for items coating was also affected by the decreased a lot. Where machinery is for processing in the vacuum environment, so need to control the pressure, here to introduce the pressure system of vacuum coating machine.
In vacuum unit, due to the need of vacuum technology, hope vacuum chamber pressure maintenance on a given value, however, due to the change of vacuum indoor put gas or vacuum pump suction rate interference factors, such as the vacuum chamber pressure deviates from the given value, so need to automatically adjust the pressure. For small vacuum pressure automatic adjustment, usually choose pressure controller to achieve them. So after research design, and many times of experiments was designed to produce the vacuum coating machine pressure control instrument control system, this is the most used in the vacuum coating equipment control device for pressure balance.
