Characteristics of vacuum pump products

Product Overview

Vacuum pumps include water ring pumpsreciprocating pump, slide valve pumpRotary vane pump、Roots pumpandDiffusion pumpWait, currently these pumps are vacuum pumps used in various industries of China's national economyThe main type of pump used in the manufacturing process. In recent years, with the sustained high-speed development of China's economy, the downstream application industry related to vacuum pumps has maintained a rapid growth momentum. At the same time, driven by factors such as the continuous expansion of vacuum pump application fields, China's vacuum pump industry has achieved sustained and stable development.

Characteristics of vacuum pump products

(1) Has a larger pumping speed within a wider pressure range;

(2) The rotor has good geometric symmetry, resulting in low vibration and smooth operation. There are gaps between the rotors and between the rotor and the housing, which do not require lubrication and have low friction loss. This can greatly reduce the driving power and achieve higher speeds;

(3) The pump chamber does not require oil sealing and lubrication, which can reduce the pollution of oil vapor to the vacuum system;

(4) There is no compression in the pump chamber and no exhaust valve. Simple and compact structure, insensitive to dust and water vapor in the extracted gas;

(5) Low compression ratio results in poor hydrogen extraction efficiency;

(6) The surface of the rotor is a complex curved cylindrical surface, which is difficult to process and inspect.

Product Description

There are many manufacturers of vacuum pumps in our country, and the annual sales revenue of all vacuum pumps is about 150 million yuan, which is only equivalent to the annual sales revenue of a vacuum pump company in the United States. Through the analysis of the vacuum pump market, we can see that the market and application areas of various vacuum pumps are constantly changing and developing.
