China 2be1 Liquid Ring Pump Wholesale

Application and characteristics
The liquid ring vacuum pumps and compressors of 2BE series are high-efficient and energy-saving products developed by our company on the basis of our scientific achievements and production experiences over the years combining with the advanced international technique of similar products. They are usually used to suction the gas without solid particle, undissolved and noncorrosive gas in order to form vacuum and pressure in the closed container. By changing the structure material, they can also be used to suction corrosive gas or use corrosive liquid as operating liquid. They are widely used in paper-making, chemical, petrification, light industry, pharmacy, instruments, metallurgy, construction, electronical appliance, coal-cleaning, mineral concentration, fertilizer, etc.

These single-stage and single-acting pumps are simple in structure, convenient in maintaining, reliable in operating, efficient and energy-saving. They can run under tough working conditions with large drainage discharge and changing load impact. 2BE vacuum pumps adopt unique polytetrafluoroethylene valve plates (former liquid ring pumps use ball valves) for their exhaust systems. Each valve plate is covered on vents in outer side of a port plate and fixed by a stainless steel baffle at its other side. Curvature of the valve plate changes with inlet pressure so that pumping medium can be discharged when it reaches the inlet pressure. Such structure avoids over-compression in a vacuum system and automatically adjusts exhausting area to lower power consumption, thus a best operating efficiency can be obtained.

We have optimized designs of key parts like distribution plate, impeller and pump shaft by simplifying their structures and improving their performances, thus energy-saving target has been reached. Dynamic balance problem is radically solved because during impeller welding, blades are formed by one-step stamping with rational molded lines and all wheel hubs are processed. The impeller and pump shaft combined by shrinkage interference fit perform reliably and smoothly. Blades of the impeller will obtain good ductility after the impeller is welded and processed by overall heat treatment, thus impact resistance and flexure resistance of the blades are fundamentally guaranteed for application under tough working condition with changing load impact. The 2BE pumps are convenient in assembly, application and maintenance and simple in operation due to their gas-water separators, several vents at different positions, vent valve manholes in pump covers and clearances between the distribution plates and impellers which are adjusted by glands at both ends of locating shafts.
