Roots vacuum pump rotor configuration
The two roots vacuum pump rotor in the pump body how to decorate, determines the overall structure of the pump, and as for the current situation, usually there are three kinds of the overall structure of the roots vacuum pump arrangement method.
Overall configuration of roots vacuum pump:
1.Vertical: two rotor axis in horizontal installations, but two rotor axis vertical plane and horizontal plane, the structure of the roots vacuum pump set horizontally into the vent, assembly and connection pipe is more convenient.
2.Horizontal: the axis of the two rotors is installed horizontally, and the plane formed by the axis of the two rotors is horizontal. The inlet of the pump of this structure is above the pump, and the exhaust port is below the pump. The lower vent is normally connected horizontally, so the inlet and outlet directions are perpendicular to each other. When the vent is connected with a three-way pipe opening in two directions, one end is connected with the exhaust pipe and the other end is dead or connected with the bypass valve.
3.Vertical shaft type: some two roots vacuum pump rotor axis and the vertical plane of the installation, the structure of the assembly clearance easy to control, the rotor assembly is convenient, cover an area of an area small, but the gear drive mechanism, such as inconvenient installation and lubrication device is also more complex.
