The unit is used for vacuum smelting, welding, drying, chemical and pharmaceutical industries, power vacuum devices and other industries as vacuum pumping. The working pressure of the unit is 133pa-5pa, and the limit vacuum that can be reached is 5pa. It has the characteristics of quick start, high pumping speed, stable performance and simple operation.
The unit is a Roots vacuum pump pumping unit, which takes roots pump as the main pump and rotary vane vacuum pump as the front pump. A electromagnetic vacuum charging valve is connected in series between the front stage pump and the main pump, which is opened and closed with the switch of the front stage pump. The electric contact vacuum switch is installed at the air inlet of the unit, so as to accurately observe the residual gas condition of the equipment or container being pumped and control the startup of roots pump.
