Industrial vacuum pump category classification
Many customers are not very clear about the classification of vacuum pumps. Previously used vacuum pumps will clearly understand which type they want to choose, but it is very difficult for users who choose the vacuum pump for the first time because a vacuum pump is available on the Internet. The classification, there will be a lot of strange articles, so that customers feel like watching flowers in the fog, after all, understanding is not so thorough.
In layman's terms, vacuum pumps fall into three categories: water-adding vacuum pumps, refueling vacuum pumps, and oil-free vacuum pumps.
1. The vacuum pump for adding water means a water ring type vacuum pump. Using water as a working fluid, suction, compression, and exhaust are realized by changing the volume of the pump chamber so as to achieve the purpose of vacuum extraction. The pump can extract water vapor and corrosive gases, its type cantilever water ring vacuum pump, 2SK-type water ring vacuum pump, SK-type water ring vacuum pump, SZ-type water ring vacuum pump, etc.;
2. The refueling vacuum pump is a rotary vane vacuum pump. The gap between the rotary vane and the pump chamber is sealed with oil. The degree of vacuum is much higher than that of a water ring vacuum pump, but steam and corrosive gases cannot be pumped.
3, oil-free vacuum pumps are often used in a clean environment, will not pollute the products produced.
