Water Ring Vacuum Pump

2BV water ring vacuum pump use and scope:

The 2BV series water ring vacuum pump is a single stage coaxial pump with integral structure. The shaft seal adopts mechanical seal, which has the characteristics of simple structure, simple installation, oil-free, safe and reliable. 2BV series water-ring vacuum pumps are suitable for pumping gas and wet steam. The suction pressure can reach 33 mbar absolute pressure (97% vacuum degree). When 2BV water-ring vacuum pump works for a long time under the condition of suction pressure below 80 mbar, it should be connected with cavitation protection tube to protect the pump. If 2BV water-ring vacuum pump is equipped with atmospheric ejector, the suction pressure can reach 10 mbar, and the ejector can be directly installed in the vacuum pump. On the suction port, when used as a compressor, the maximum pressure is 0.26 MPa (absolute pressure).

2BE water ring vacuum pump characteristics and applications :

2BE water ring vacuum pump and compressor are high efficiency and energy-saving products developed by our factory on the basis of many years of scientific research and production experience, combined with advanced technology of imported products. Usually used for suction of gases without solid particles, insoluble in water and corrosive, in order to form vacuum and pressure in sealed containers. By changing the structure material, it can also be used to suck corrosive gases or working liquids with corrosive liquids. It is widely used in papermaking, chemical industry, petrochemical industry, light industry, pharmaceuticals, food, metallurgy, building materials, stone tools, coal washing, mineral processing, fertilizer and other industries. 2BE water ring vacuum pump adopts single-stage single-action structure, which has the advantages of simple structure, convenient maintenance, reliable operation, high efficiency and energy saving. Compared with SK, 2SK and SZ series water-ring vacuum pumps widely used in China, they have obvious advantages of high vacuum degree and low power consumption. They are ideal substitutes for SK, 2SK and SZ series water-ring vacuum pumps. The main features of 2BE water-ring vacuum pumps and compressors produced by our company are as follows:
The bearings of 2BE water ring vacuum pump are all NSK or NTN imported bearings, which ensure the accurate positioning of the impeller of 2BE1 vacuum pump and high stability in operation. The impeller of 2BE water ring vacuum pump is made of nodular cast iron or welded with steel plate and stainless steel plate, which fully guarantees the stability of the impeller of 2BE1 vacuum pump under various adverse conditions, and greatly improves the service life of 2BE1 vacuum pump. The pump body of 2BE water ring vacuum pump is made of steel plate or stainless steel plate, which improves the service life of 2BE1 vacuum pump. The axle sleeve of 2BE1 vacuum pump of 2BE type water ring vacuum pump is the most easily damaged part. The company is made of stainless steel, and its service life is five times longer than that of ordinary material. The belt pulley (belt drive) of 2BE water ring vacuum pump adopts standard high precision conical sheath pulley, which has reliable operation, long belt life and convenient disassembly. The coupling (direct drive) of 2BE water ring vacuum pump adopts standard high strength elastic coupling, and the elastic components are made of polyurethane material. It runs stably and reliably with long service life. The unique upper air-water separator of 2BE water-ring vacuum pump saves space and effectively reduces noise. All the castings of 2BE water ring vacuum pump are made of resin sand with good surface quality. The surface of castings need not be greased, so that the heat dissipation effect of 2BE1 vacuum pump is the best. The mechanical seal (optional parts) of 2BE water ring vacuum pump are all imported parts, which fully ensures that the 2BE1 series vacuum pump has no leakage during long-term operation.
