How Vacuum Pumps Work Vacuum pumps are devices that create, improve, and maintain vacuum in a closed space in a variety of ways. A vacuum pump can be defined as a device or device that uses a mechanical, physical, chemical, or physicochemical method to evacuate a pumped container to obtain a vacuum.
Classification of Vacuum Pumps With the development of vacuum applications, the variety of vacuum pumps has evolved. According to its working principle, it can basically be divided into two types, namely gas transfer pump and gas trap pump. With the application of vacuum application technology in the field of production and scientific research, the requirements of the pressure range are wider and wider. Most of them need to be vacuum pumped by several vacuum pumps to meet the requirements of production and scientific research process. The vacuum application department covers a wide range of working pressures, so any type of vacuum pump cannot be fully applied to all working pressure ranges. It can only be used according to different working pressure ranges and different working requirements. Vacuum pump.
What kind of vacuum pump is suitable for the laboratory of colleges and universities? When selecting laboratory equipment, whether it is evaporation, distillation, crystallization, drying, sublimation, filtration decompression or degassing, vacuum pumps are needed to provide vacuum conditions. According to different needs, the degree of vacuum is different, and the required laboratory instruments are also different. In the laboratory of colleges and universities, you can choose SHB-IV double A type double-sided of the Great Wall Instrument circulating water multi-purpose vacuum pump. This vacuum pump is suitable for teachers and students to do experiments together. It has the same characteristics on both sides, and the four taps can be pumped at the same time. Vacuum, four meters display, do not affect each other, can be played by four operators at the same time, greatly reducing the cost of the laboratory, and this machine is convenient for teachers to visually demonstrate, directly monitor the experimental situation, students can also boot and shut down on either side. You can also choose SHB-B95. This machine is a new type of multi-purpose vacuum pump designed by Great Wall Instruments. It provides vacuum conditions for the chemical laboratory and can provide circulating cooling water to the reaction device. The water added into the water tank can be recycled and reused. The phenomenon of a large amount of wasted water when the tap water is directly flushed to obtain a vacuum.
Circulating water type multi-purpose vacuum pump working principle Circulating water type multi-purpose vacuum pump uses circulating water as a working fluid, and uses a fluid jet to generate a vacuum to inject a vacuum to generate a vacuum.
If a vacuum pump that requires a large pumping volume should choose which type of vacuum pump, if it is a vacuum pump that requires a large pumping volume, it is recommended to use the SHB-E type circulating water type multi-purpose vacuum pump. This machine is specially designed for drug purification, large equipment, pilot test and small, The supporting vacuum pump developed by the medium-volume production process has a large pumping capacity. It can be used in multiple 10~50 liter rotary evaporators (the number is determined by the reactor specifications). It can be used in multiple reactors (the number of reactors is determined by the reactor specifications). It can also be used instead of the rotary vane vacuum pump.
