How to check the exhaust valve in vacuum system?

In vacuum technology, vacuum acquisition and measurement are the two most important aspects. In vacuum system, vacuum acquisition equipment and measuring instrument are essential.

At present, the system is widely used in electronic semiconductor industry, photoelectric backlight module, machining and other industries. With the development of electronic technology and computer technology, all kinds of vacuum equipment are developing towards the direction of high pumping speed, high vacuum limit and no pollution.

A variety of vacuum measuring equipment and microcomputers, with digital display, data printing, automatic monitoring and automatic range switching and other functions. After the vacuum system starts, the whole operation process can be fully automatic control.

In the process of operation, the vacuum degree of the vacuum system always fluctuates within the allowed range, which can be adjusted according to the requirements of users. The vacuum system of screw vacuum pump, rotary vane vacuum pump, rotary vane vacuum pump and water ring vacuum pump is adopted to achieve the best technological flow.

When high vacuum is required, high vacuum pumps are usually placed in series in vacuum systems. When high vacuum pumps are in series, valves are usually installed at the inlet and outlet of the pump to keep a separate vacuum.

When the system is started, the main vacuum pump starts to work, until the vacuum degree in the vacuum tank reaches the set upper limit, the vacuum pump automatically stops running, and the central vacuum system automatically cuts off the pipeline through the vacuum check valve to maintain the vacuum degree.
