About The Classification Of Vacuum Pump
Diaphragm vacuum pumps have the advantages of advanced design, wide work scope, and long service life. The pumps are mainly applied in the areas of medical product analysis, fine chemical engineering, biochemical pharmaceuticals, food detection, and public security criminal investigation technology. Furthermore, the diaphragm vacuum pumps are the products which support precision analytical instrument, and they are necessary equipment for laboratories.
Most of the diaphragm vacuum pumps can be operated without any working medium and do not produce any pollutants. At the same time, the gas exchange chambers of the pumps are equipped with filter materials so that a clean vacuum effect or positive pressure power will be guaranteed.
In general, diaphragm vacuum pumps always adopt new technology and new materials. They have compact and reasonable structures as well as small volume, low weight, and easy movement. In a word, the stable operation of diaphragm vacuum pumps can ensure the ideal vacuum effect or high flow capacity of the air current.
Moreover, diaphragm vacuum pumps adopt membrane movement without producing heat and frictional loss, which leads to long service life. Also, diaphragm vacuum pumps are equipped with a self-cooling exhaust system which can ensure 24 hours of continuous work.
Diaphragm vacuum pump, with advanced design, high work efficiency, and long service life, is a new generation of high-tech integrated products. Mainly used in medical and pharmaceutical product analysis, fine chemicals, biochemical pharmacy, food inspection, public security criminal investigation technology, etc. It is a product for its precision chromatography instruments and one of the necessary equipment for the laboratory.

The diaphragm vacuum pump body is made of aluminum alloy die-casting, which is light and beautiful, has a wide application range, and the air chamber is made of nylon material. It has high corrosion resistance and can meet the requirements of various working environments.
As a vacuum filtration device, the vacuum pump is frequently used and it can be classified into four general kinds.
Liquid ring pump
Although the liquid ring pump is a rough vacuum pump, it still has a large market in petroleum, chemical, electric power, textile, paper, and pharmaceutical fields. Since most of the liquid ring pump is casting and belongs to a labor-intensive product, it has a competitive advantage in price. The key is to improve the design, reduce volume and weight, improve efficiency, and reduce energy consumption.
Slide valve pump
Because the spool valve pump is more durable and reliable, all kinds of vacuum furnaces, coating machines, drying and impregnation equipment at home and abroad use the slide valve pump as the foreline pump.
Direct coupling rotary vane pump
With the continuous expansion of vacuum technology in various application fields, the demand for direct-coupled rotary vane pumps is increasing. It requires heavy processing and assembly work, and the price is very low.
From the sales of the world-known companies, the roots pump production is not big. But it has been used in petroleum, chemical, plastics, pesticides, turbine rotor dynamic balance, aerospace space simulation, and other devices.
