Working principle of 2BE water ring vacuum pump

The B water ring vacuum pump is a positive displacement pump that uses changes in volume to achieve the purpose of suction and exhaust. Its working principle is as follows: The impeller is eccentrically installed in the B water ring vacuum pump. When the impeller rotates. The water is affected by centrifugal force and forms a rotating water ring on the inner wall of the pump body. The water ring is not tangent to the wheel and rotates in the direction of the arrow. During the first half of the rotation, the inner surface of the water ring gradually separates from the wheel, so the impeller blade The space formed between gradually expands, the gas pressure in the space decreases, and the gas is sucked into the space.
During the second half of the rotation, the inner surface of the water ring gradually approaches the impeller, the space between the blades gradually shrinks, and the air pressure increases. When it is higher than the exhaust port pressure, the gas is discharged. Up to this point, every time the impeller rotates Once a week, the blades are changed, many spaces are working continuously, and the B water ring vacuum pump continuously sucks gas. Because during the working process, work generates heat, which will cause the working water ring to heat up, and at the same time, part of the water and gas will be discharged. Therefore, water must be continuously supplied to the pump during the process to cool and replenish the water consumed in the pump to meet the working requirements.
The normal operation of B water ring vacuum pump must follow the working principle, and the design must also be based on the principle. This shows the importance of understanding the principle.
