Dry vacuum pump makes the working volume oil-free, so it brings many benefits. First of all, it enhances the pump's reliability. Dry pumps are not affected by water vapor or dust particles as oil seal pumps, so they are more durable and require less maintenance. Reducing oil consumption also means reducing the cost of serious disposal of oil. The use of dry vacuum pumps also reduces the possible contamination to a smaller level, which may be present in the oil - affecting the performance of the pump, or in some extreme conditions.
At present, most of the dry vacuum pumps used in the vacuum industry use oil, water or other polymers as the working medium of the pump, which plays a variety of functions such as cooling, sealing and smoothing in the pump. With the development of science and technology and the expansion of vacuum application scope, the original dry vacuum pump and its pumping system present two urgent problems: one is the backflow of the working medium of the pump pollutes the pumped container, which affects the quality and quantity of products in many cases, and increases the maintenance cost of equipment. Secondly, due to the reaction material in some process, the medium in the vacuum pump is seriously degenerated, so that the pump can not work normally.
As for the common oil-free vacuum system, although the oil sealed vacuum pump and the accessories such as cold trap or adsorption trap can be used to avoid backflow, it can not completely deal with the problem and make the system complex. The application of appropriate type of dry vacuum pump can achieve the ideal application effect.
