Because the spool valve pump is relatively durable and reliable, various vacuum furnaces, coating machines, drying, dipping and other equipment at home and abroad use the spool valve pump as the backi

Although the liquid ring pump is a rough vacuum pump, it still has a large market in China's petroleum, chemical, electric power, textile, paper, medicine and other fields. The working principle of li

The two rotors of the vacuum pump are operated relatively synchronously through a pair of high-precision gears. The driving shaft is connected with the motor through a coupling. There are two main typ

The intake port of the horizontal pump is on the top and the exhaust port is on the bottom. Sometimes in order to facilitate the installation and connection of the vacuum system pipeline, the exhaust

The arrangement of the pump body of the vacuum pump determines the overall structure of the pump. The intake and exhaust ports of the vertical structure are set horizontally, which is convenient for a

At present, the annual sales of the global vacuum pump market is about 2 billion US dollars, and the annual growth rate is about 7%.There are many manufacturers of vacuum pumps in my country, and the

The vacuum pump is a product with a large quantity and a wide range, with a large output and a low output value, but it is indeed an essential basic product that directly affects the performance and q

The vacuum drying oven has requirements for the materials to be dried. One is that it cannot contain a large amount of water, and the other is that it cannot contain organic compounds; both of them wi

Vacuum pumps include water ring pumps, reciprocating pumps, slide valve pumps, rotary vane pumps, Roots pumps and diffusion pumps, etc. At present, these pumps are the indispensable main pumps in the

The vacuum pump is a rotary variable volume. The vacuum pump must be used with the backing pump. It has a large pumping speed in a wide pressure range and is not sensitive to the dust and water vapor

According to the working principle of vacuum pump, vacuum pump can be basically divided into two types, namely gas capture pump and gas transmission pump. It is widely used in metallurgy, chemical ind

A vacuum pump refers to a device or equipment that uses mechanical, physical, chemical or physical-chemical methods to evacuate the pumped container to obtain a vacuum. In layman's terms, a vacuum pum
