What is dry rotary vacuum pump

With the development of vacuum application, there are many kinds of vacuum pumps, whose pumping speed is from 0.5 liter per second to hundreds of thousands and millions of liters per second. According to the working principle of vacuum pump, vacuum pump can be basically divided into two types, namely gas capture pump and gas transfer pump.

Vacuum pumps are widely classified, mainly including oil-free vacuum pump, multiple vacuum pump, dry rotary vacuum pump, dry vacuum pump, water ring vacuum pump, slide valve vacuum pump, roots blower, roots rotary vane vacuum unit, roots water ring vacuum unit, etc.

Vacuum pump is widely used in plastic machinery, pesticide chemical industry, dye chemical industry, brick and tile machinery, low-temperature equipment, papermaking machinery, pharmaceutical chemical industry, food machinery, industrial electric furnace, electronic industry, vacuum equipment, fertilizer, metallurgy, petroleum, mining, foundation treatment and other fields.

Water ring vacuum pump is a new generation of water ring vacuum pump, which is developed on the basis of raw water ring vacuum pump to meet the requirement of water suction. It has advanced design and novel structure, and is suitable for various demanding and complex application fields. It can suck a large amount of water vapor and condensable medium, which is not easy to cause danger when it sucks flammable, explosive, toxic and corrosive gases. Therefore, it can be widely used in machinery, petroleum, chemical industry, electric power, pharmaceutical, food, ceramics, sugar manufacturing, printing and dyeing, metallurgy, plastic, tile, leather and other industries, especially suitable for supporting use of plastics.

People often encounter the transportation of chemical gas in the process of use, which requires the introduction of a new concept of anti-corrosion pump. It uses ceramics, stainless steel, alloy and other special media to make the flow passage part, which really meets the requirements of “wear resistance, acid resistance, alkali resistance and high temperature resistance”.

Dry rotary vacuum pump is a kind of device which can produce, improve and maintain vacuum in a closed space by various methods. Vacuum pump can be defined as a device or equipment that uses mechanical, physical, chemical or physical chemical methods to extract air from the container to obtain vacuum. With the development of vacuum application, there are many kinds of vacuum pumps, whose pumping speed is from 0.5 liter per second to hundreds of thousands and millions of liters per second.

According to the working principle of vacuum pump, vacuum pump can be basically divided into two types, namely, gas transfer pump and gas capture pump. With the application of vacuum technology in the field of production and scientific research, the pressure range of its application is becoming wider and wider. Most vacuum pumps need to be composed of several vacuum pumping systems to pump together to meet the requirements of the production and scientific research process. Because the working pressure range involved in the vacuum application department is very wide, it is impossible for any type of vacuum pump to be completely suitable For all working pressure ranges, only different types of vacuum pumps can be used according to different working pressure ranges and different working requirements. In order to use conveniently and meet the needs of various vacuum processes, various vacuum pumps are sometimes combined according to their performance requirements and applied in the form of units.

Dry rotary vacuum pump is an essential main pump in the application of vacuum technology in various industries.
