2BV water ring vacuum pump Working principleThe working principle of the 2BV water ring vacuum pump must be understood by every relevant worker, because it is related to the operator's understanding of the equipment and the proficiency of the operation, and indirectly affects the work efficiency. Therefore, the following editors summarize it for everyone Let's take a look at the working principle with the icon:As shown in the figure, the impeller is eccentrically installed in the pump body, and a certain height of water is injected into the pump when starting. Therefore, when the impeller 3 rotates, the water is subjected to centrifugal force to form a rotating water ring 1 on the inner wall of the pump. The inner surface of the lower part of the 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 of the 2BV water ring vacuum pump gradually disengages from the hub. Rotating, the space gradually expands, the space gas pressure decreases, and the gas is sucked in from the disk suction port; during the second half of the rotation, the inner surface of the water ring gradually approaches the hub, the space between the blades gradually shrinks, and the space gas pressure increases. When the pressure is higher than the exhaust port, the gas between the blades is discharged from the disc exhaust port. In this way, every time the impeller rotates for one week, the space between the blades sucks and exhausts once. Many spaces work continuously, and the equipment continuously sucks or pressurizes the gas.Looking at the working principle of the 2BV water ring vacuum pump above, we found that during the operation of the pump, the working water ring heats up, and at the same time part of the water and gas are discharged together. Therefore, the pump must be continuously supplied with water to meet the working requirements of the pump. I hope that after fully understanding the internal structure principle of the equipment, it will bring some help to everyone's future work.
