Summary
The water (liquid) ring vacuum pump is mainly used for axial suction of gas without particles. The working medium is clean water at room temperature, and other media such as acid and alkali can also be used as the working fluid for special requirements. Its gas volume range is 4.8-4503/mim, the ultimate vacuum degree is 33hpa or 160hpa, and the efficiency is 40-65%. It is widely used in industries such as electricity, chemical engineering, coal mining, papermaking, plastic machinery, environmental protection, medical treatment, pharmaceuticals, food, mineral processing, petrochemical, light industry, packaging, metallurgy, building materials, stone tools, fertilizers, etc.
Working principle
In general, the working fluid of a water ring vacuum pump is mostly directly discharged, as shown in Figure 1:
Fig. 1 Schematic Diagram of Working Fluid Supply and Discharge of General Water Ring Vacuum Pump
The water discharged by the water ring vacuum pump enters a large circulating water tank or is directly discharged. This water supply and drainage method is convenient to connect, simple to use, and widely used in practical applications.
2BW series liquid ring vacuum pump closed circuit circulation system is a complete set of equipment composed of 2BV or 2BE series liquid ring vacuum pump, steam water separator, heat exchanger and various pipeline accessories. Compared with a single liquid ring vacuum pump, it is more convenient to install. Because the working fluid can be recycled, the system greatly reduces the consumption of working fluid and the pollution to the environment, so it has obvious advantages in situations where the extracted gas contains toxic, organic solvents, inflammables and explosives.
The working fluid of the liquid ring vacuum pump closed-circuit circulating system can use a variety of media: water, methanol, ethanol, xylene, aniline acetone, and other organic solvents, transformer oil, etc.
