2BE series liquid ring vacuum pumps and compressors 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 similar products in the world. Usually used for suction of non-solid particles, insoluble in water, non-corrosive gases, in order to form vacuum and pressure in sealed containers. It can also be used to suck corrosive gases or use corrosive liquids as working fluids by changing the material of overflow parts. 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.
This series of pumps adopt single-stage single-acting structure, which has the advantages of simple structure, convenient maintenance, reliable operation, high efficiency and energy saving, and can adapt to the bad working conditions such as large drainage and load impact fluctuation. The exhaust system of 2BE series vacuum pump adopts unique PTFE valve plate structure (raw water ring pump is ball valve structure). The valve plate covers the exhaust hole on the outer side of the flat disc and is positioned by the stainless steel baffle on the other side. The bending degree of the valve plate varies with the change of the inlet pressure, so that the pumping medium can be discharged out of the pump when it reaches the inlet pressure. The structure avoids over-compression in the vacuum system and can automatically adjust the exhaust area to reduce energy consumption so as to achieve the best operating efficiency.
The key parts, such as distribution plate, impeller and pump shaft, have been optimized systematically. The structure has been simplified, the performance has been improved, and the energy-saving has been realized. Welded impeller has been used. The blade has been stamped and shaped at one time, and the profile is reasonable. The problem of dynamic balance has been fundamentally solved by the complete processing of wheel upset. The impeller and the pump shaft are fitted with thermal load interference. The performance is reliable and the operation is stable. After welding, the impeller runs well in heat treatment, and the blade has good toughness, which guarantees the impact resistance and bending resistance of the blade, and can adapt to the bad working conditions of load impact fluctuation. 2BE series pumps, with air-water separator, multi-position with exhaust outlet, pump cover with exhaust valve overhaul window, impeller and distribution plate clearance through positioning shaft two ends of pressure cover adjustment, easy installation and use, simple operation, easy maintenance.
The liquid ring vacuum pump in our factory has been strictly inspected and tested by the testing center before leaving the factory. Its performance is superior, reliable and durable.
