Slide valve vacuum pump working principle and structure

Sliding valve vacuum pumps, which function to remove specific gases or contain small amounts of condensable vapors, are nowadays widely used in vacuum smelting, vacuum drying, vacuum impregnation and other vacuum operations. Sliding valve vacuum pump principle is to use the slide valve body to change the suction chamber volume, so called slide valve pump. Sliding valve vacuum pump working principle and structure Sliding valve vacuum pump working principle: Sliding valve vacuum pump mainly by the pump body and the eccentric rotation of the spool, semi-circular slide valve guide, exhaust valve, shaft and other components (See picture). The pump body is equipped with a slide valve ring (4), an eccentric wheel (3) is arranged in the slide valve ring, the eccentric wheel is fixed on the shaft (2), and the axis coincides with the center line of the pump body. The slide valve ring is provided with a rectangular slide valve stem (5), which can slide up and down and swing left and right in the semicircular slide valve guide (7). Therefore, the pump chamber is separated into the valve slide rings A and B Two rooms. Pump in operation, due to the cyclical changes in the volume of A, B two chamber, so that the evacuated gas into the gradually increasing volume of the suction chamber; the same time, in the exhaust chamber with its reduced volume and gas compression , And out of the pump through the exhaust valve. Two-stage type of slide valve pump, in fact, by two single-stage pump in series. Its high and low vacuum chamber in the same pump body, some are cast directly into a whole, some are pressed into the partition into the pump chamber into high and low two rooms. Sliding valve vacuum pump because of its structural characteristics, generally divided into single-stage pump and two-stage pump two, but there are vertical and horizontal structure of two types. With the development of science and technology, the slide valve mechanical vacuum pump has also been greatly reformed, and its use is also more easy to use and convenient. Further study of its working principle will be beneficial to the improvement and improvement of related technologies.
