Vacuum pump introduction:
Vacuum pump is a rotary variable volume gas transfer pump. The vacuum pump must be used in conjunction with the front pump for greater pumping speed over a wider pressure range. It is insensitive to dust and water vapor in the extracted gas. Widely used in metallurgy, chemical, food, electronic coatings and other industries.
Development of vacuum pump:
Vacuum pumps include dry screw vacuum pump, water ring pump, reciprocating pump, slide valve pump, rotary vane pump, roots pump and diffusion pump. These pumps are indispensable main pumps in the application of vacuum technology in all walks of life of our national economy. In recent years, with the continuous and rapid development of China's economy, the downstream application industry of vacuum pump has maintained the momentum of rapid growth. At the same time, due to the continuous expansion of vacuum pump applications and other factors, China's vacuum pump industry has achieved sustained and stable development.
According to the data of "China vacuum pump manufacturing in-depth survey and 2013-2017 investment forecast analysis report", it is an indisputable fact that foreign enterprises enter the Chinese vacuum pump market. Japanese vacuum cleaners are spread all over the country, German rebo is expanding in China, American thysser group, south Korean yousei and other internationally renowned manufacturers are also looking for partners to build and manufacture in China. The foundation. They have a huge appetite and are supplying whale vacuum pumps on the market. In recent years, although some domestic enterprises gradually rise and occupy the leading position in the vacuum pump market, most of them have poor research and development ability. Compared with foreign counterparts, high-end products are still at a technological disadvantage.
