2BV water ring vacuum pump features and maintenance methods!

Working principle of 2BV water ring vacuum pump

When the impeller of 2BV water ring vacuum pump rotates against the market direction, water is thrown around by the impeller. Due to the effect of centrifugal force, water forms a closed ring of approximately equal thickness depending on the shape of the pump chamber. The inner surface of the lower part of the water ring is just tangent to the impeller box, and the inner surface of the upper part of the water ring is just in contact with the blade tip (in fact, the blade has a certain insertion depth in the water ring). At this time, a crescent space is formed between the impeller shell and the inner interface of the water ring, which is divided into several small cavities equal to the number of blades by the impeller blades of 2BV water ring vacuum pump. If the bottom of the water ring vacuum pump impeller with 2 bv 0 ℃ as the starting point, so in front of the rotating impeller 180 ℃ when the small cavity volume changes from small to big, and on the face of inspiratory mouth, air is sucked into at this time, when the suction at the end of the small cavity is isolated from the rest of inspiratory mouth, when the impeller to rotate, small cavity from large to small, make the gas is compressed, when small cavity with vent gas is expelled outside 2 bv water ring vacuum pump.
2BV water ring vacuum pump is to achieve suction, compression and exhaust by the change of pump chamber volume, so it belongs to the variable volume vacuum pump.



The main features



1, the machine pump coaxial type direct connection design, saves the space, easy to install.



2, 2BV water ring vacuum pump all USES the overseas import mechanical seal as the standard configuration.



3. All 2BV water ring vacuum pumps are equipped with cavitation protection tube interfaces. If they work under extreme pressure, the cavitation sound can be eliminated by opening the cavitation protection tube interface (or connecting with the separator) to maximize the suction effect and protect the 2BV water ring vacuum pump.



4, aluminum bronze impeller high strength, durable, and improve the corrosion resistance of 2BV water ring vacuum pump. If the flow parts are made of stainless steel, they can work in a more demanding environment.



5. The unique flexible exhaust port design ensures the best efficiency of 2BV water ring vacuum pump in its performance range without over compression.



6. All Y2 series motors are adopted, and the protection grade is IP54 and IP55 (common is IP44).



7. 2BV water ring vacuum pump adopts NTN or NSK imported bearings.
