Cycloidal vacuum pump features

Cycloidal vacuum pump features

A trochoidal vacuum pump is a type of circumferential rotor in the pump chamber as a regular planetary motion vacuum pump, and the trochoidal vacuum pump is characterized by a vacuum pump in which the working chamber volume periodically changes to achieve pumping. Its use to make up for the lack of slide valve pump, in the field of vacuum pumps is an innovative product.

The characteristics of trochoidal vacuum pump:

From the point of view of the construction and use effect, the characteristics of the trochoidal vacuum pump are mainly reflected in the following aspects:

1) The balance of the trochoidal vacuum pump is good, its operation is more stable, the vibration is also small, the speed can be increased, can be achieved small size, pumping speed, suitable for the development of large pumping speed vacuum pump.

2) Because the suction line is short and thick, it helps to increase the pumping speed at low pressure. Therefore, the pumping speed characteristic of the trochoidal vacuum pump in the low pressure range is superior to that of the slide pump.

3) The rotor and the pump body of the trochoidal vacuum pump are the meshing motion of a pair of conjugate tooth pairs, so dust and small particles have little effect on the effect.

4) The trochoidal vacuum pump can adapt to the higher temperature working environment, and the temperature of the pump chamber can be kept high to extract a large amount of condensable water vapor.

The trochoidal vacuum pump still has a large pumping speed in the pressure range of 1 to 10 Pa. Because of this advantage, the trochoidal vacuum pump is suitable for large displacement devices in the vacuum industry. At present, the trochoidal vacuum pump is widely used in metallurgy, heat treatment, drying, impregnation and other industries. Its influence has also become more apparent.
