Vacuum pump classification, the role of vacuum coating equipment
The vacuum pump is a gas transfer pump that is rotated by a variable volume. The vacuum pump has a front pump and a large pumping speed. It is widely used in the vacuum coating industry and plays a huge role in vacuum coating.
Vacuum pumps can be divided into water ring vacuum pumps, rotary vane vacuum pumps, dry vacuum pumps, and molecular vacuum pumps.
The water ring vacuum pump has 2BV series direct connection type, SKA series, SK series, 2SK series.

SKA water ring vacuum pump
The rotary vane vacuum pump has XD series single-stage selection, X series single-stage rotary type, and 2X series rotary type.
XD series single-stage rotary vane vacuum pump features: smooth operation, low vibration, no need for grounding bolts. The isolation valve automatically restarted in the pump can place the pump oil back into the pumping system, no need to take over the exhaust, and there is an oil mist eliminator.

2X series rotary vane vacuum pump features: can be used alone, can be used as a front pump of diffusion pump, molecular pump, booster pump.
Dry vacuum pump features: no pollution to the pumping system and environment, can be used to remove two fine particles or liquid, can be used alone or with a Roots hollow pump to form a vacuum unit, the ultimate vacuum is 10pa.
The vacuum pump uses mechanical, physical, chemical and other methods to evacuate the vacuum equipment container in the vacuum coating equipment to achieve the vacuum degree acquisition and maintenance. In the vacuum coating equipment, the vacuum pump and other components such as vacuum valve and measuring instrument 'link tube The road is composed of a vacuum system, which is an important part of the vacuum coating machine to achieve vacuum coating.
