2BE3 series Liquid ring vacuum pump

Products

一、Features and USES of 2BE water ring vacuum pump:

The 2BE water ring vacuum pump and compressor is a highly efficient and energy-saving product developed by our factory on the basis of years of scientific research achievements and production experience, combined with advanced technology of imported products. It is usually used for suction without solid particles, insoluble in water and non-corrosive gases, so as to form vacuum and pressure in sealed container. By changing the structural material, it can also be used to absorb corrosive gas or to work with corrosive liquid. It is widely used in papermaking, chemical, petrochemical, light industry, pharmacy, food, metallurgy, building materials, stone tools, coal washing, mineral dressing, fertilizer and so on.

二.Characteristics of water ring vacuum pump:

1. High reliability

Due to this series of pump impeller and shaft hot charging interference fit, shaft and bearing safety coefficient is big, thus has quite make the reliability of the impeller welding, wheel and blade all processing, fundamentally solve the problem of dynamic balance, stable running noise.

2. Convenient maintenance

Because there is no set inspection hole on the end cover of the pump, thus it can be easily see internal structure, and can change without dismantling the pump exhaust valve plate, also packing replacement can be, under the condition of pump in the demolition could not easy to release.

3. High efficiency and energy saving

The series pump adopts the system optimization design, adopted the flexible design of exhaust valve, avoiding the gas compression of compression, by adjusting the exhaust area to reduce the energy consumption, ultimately achieve the best efficiency.

4. Adaptive impact load.

Blade USES the steel plate stamping forming, a mountain type line to ensure that the overall heat treatment, welding impeller blade has good toughness, its impact resistant. Bending resistance to fundamental guarantee, adapt to the impact load.

三.Working principle of water ring vacuum pump:

The water ring vacuum pump is a displacement pump, which USES the change of volume size to achieve the suction and exhaust purpose.

The impeller is mounted eccentrically in the pump, when the impeller is rotated. Water is affected by centrifugal force function and in form a rotating water ring pump body wall, water ring is not round and tangent, along the direction of arrow rotation, in the first half of the turn in the process of inner surface gradually away from the wheel, water ring so space is formed between impeller blade gradually expand, space gas pressure is reduced, air is sucked into space; In the process of the half turn, water ring surface and wheel near gradually, shrinking the space between the blades, air pressure, higher than the outlet pressure, the gas is expelled, thus each rotating impeller week, one change between blade, a lot of space work, continuous suction gas pump.

Because in the process of work, work to generate heat, hot water ring, jobs at the same time, some of the water and gas is expelled, therefore must continue to pump water supply in the process, to cool and supplement the consumption of water in the pump, meet the job requirements.
