Roots vacuum unit used in vacuum metallurgy industry

Roots vacuum unit is widely used in vacuum degassing, vacuum melting, liquid steel vacuum treatment, space simulation, low-density wind tunnel and other devices to extract corrosive gas in vacuum metallurgy industry. It can also be used in distillation, evaporation, drying and other production processes of chemical industry, food, medicine, motor manufacturing and other industries.

When working, the pumped gas enters between the rotor and the pump body through the air inlet. At this time, a rotor and the pump body separate the gas from the air inlet, and the separated gas is sent to the exhaust port during the continuous rotation of the rotor. Space is in a closed state, therefore, there is no compression and expansion. But when the peak of the rotor turns to the edge of the exhaust port, because the pressure of the V part is lower than that of the exhaust port, in order to make the pressure in the connected volume uniform, the gas will diffuse from the exhaust port to the V area, and the diffusion direction is opposite to the rotation direction of the rotor. When the rotor rotates again, the gas at V is compressed to the exhaust port to discharge it. At this time, the other side of the rotor is connected with the air inlet to inhale the gas. When the rotor rotates continuously, the above air extraction process is repeated to continuously discharge the gas flowing in. This working process is equivalent to that the rotor space increases from a small value to a large value, and then decreases from a large value to a small value. This is the volume principle of Roots vacuum pump.
