Water ring vacuum pump belt pulley transmission split large vacuum pump

1、 Application and scope of 2BEC series water ring vacuum pump 2BEC series water ring vacuum pump is used to pump air or other non corrosive, insoluble in water and no solid particles. with The vacuum or pressure is formed in the closed container to meet the process requirements. A small amount of liquid is allowed to be mixed in the inhaled gas. 2BEC series vacuum pumps are widely used in machinery, petroleum, chemical, pharmaceutical, food, sugar, metallurgy, papermaking, coal washing and beneficiation Mining, building materials, ceramics, printing and dyeing, light industry, thermal power generation and electronic industry. Because in the working process, the pump to the gas compression is isothermal, so it can pump flammable and explosive gas The corrosive gas can be aspirated or the corrosive liquid can be used as the working fluid by changing the structural materials. 2、 Model significance of 2be series water ring vacuum pump

4、 Working principle of 2be series water ring vacuum pump Water ring vacuum pump is a positive displacement pump, which uses the change of volume to achieve the purpose of suction and exhaust. As shown in Figure 1, the impeller is eccentrically installed in the pump body, when the impeller rotates. Under the action of centrifugal force, water forms a rotating water ring on the inner wall of the pump body. The upper part of the water ring is tangent to the hub and rotates in the direction of the arrow. During the first half of the rotation, the inner surface of the water ring is gradually separated from the hub, so the space formed between the impeller blades is gradually expanded, the space gas pressure is reduced, and the gas is sucked into the space; in the process of the second half rotation, the inner surface of the water ring is gradually close to the hub, At this point, the pressure of the impeller is higher than that of the impeller, and the air pressure is gradually reduced between the blades. 5、 Characteristics of 2be series water ring vacuum pump 1. High security Due to the hot fit of impeller and shaft, the safety factor of shaft and bearing is large, so it has high safety The impeller is welded and the hub and blade are fully processed, which essentially solves the problem of dynamic balance and runs stably with low noise. 2. Convenient maintenance Because the inspection hole is set on the end cover of the pump, it is convenient to check the internal structure, and the suction and exhaust can be replaced without removing the pump Valve plate, in addition, the replacement of packing can also be carried out without removing the pump cover, which is very convenient. 3. High energy saving efficiency This series of pumps adopts system optimization design and flexible exhaust valve design to avoid over compression in gas compression The exhaust area is adjusted dynamically to reduce energy consumption so as to achieve excellent operation efficiency. 4. Adapt to impact load The blade is formed by one-time stamping of steel plate, and the impeller is welded for heat treatment as a whole The anti impact and anti bending ability can be fundamentally protected to adapt to the impact load.
