What is the principle of the roots pump and the roots pump?

The roots pump is essentially a product of the vacuum pump, which is the same as the cam pump, but the rotor is the roots type. It can transport liquid viscosity for tens of thousands of cps.

The roots pump mainly consists of two rotations in the opposite direction in the pump body, which are driven by a pair of synchronous gears. The rotor, like a cam pump, has a double leaf and a trifoliate and multileaf blade. There are many kinds of shapes.

The rotor pump Luo Bo, in the pump body is engaged with each other, but with a gap. The size of the gap depends mainly on the viscosity of the liquid. It must be adjusted to increase the gap over a certain range of viscosity.

Figure 233 is the working principle of a two leaf roots pump and a three leaf roots pump. The principle is similar to the gear pump. When the rotor is rotated, the liquid in the space formed by the pump body is discharged from the suction chamber to the discharge chamber along the wall of the pump body. When the shaft rotates a circle, double roots pump suction and discharge two times each, and clover Roots pump, each row three times.

The main feature of the roots pump is that the surface of the rotor does not need to be lubricated and has no wear. It is more efficient than a gear pump, which is more efficient than a gear pump. But without self-priming, the speed of the pump is also affected by the viscosity of the liquid. When the viscosity exceeds a certain value, it is necessary to reduce the pump speed to change the rotor clearance, the shape of the rotor and the speed of the pump. This pump can meet the wide range of use.
