2BV Vacuum Pump Working Principle

In the operation of 2BV vacuum pump, we generally need to master its basic performance and working object, how it works, and what effect it plays in the work, which will have absolute effect on our future use, so before that, we need to understand its working principle, so it will be much simpler to deal with the problem of failure in the later stage.

The impeller 3 is eccentrically installed in the body of 2BV vacuum pump and injects a certain height of water into the pump when starting. Therefore, when the impeller 3 rotates, water forms a rotating water ring 1 on the inner wall of the pump under the action of centrifugal force. The inner surface of the water ring is tangent to the hub and rotates along the arrow direction. During the first half of the rotation, the inner surface of the water ring gradually separates from the hub, so water is formed between the impeller blades and the hub. The annulus forms a closed space, with the impeller rotating, the space expands gradually, the space gas pressure decreases, and the gas is absorbed from the disk suction port; in the latter half-turn process, the inner surface of the water ring gradually approaches the hub, the space between the blades gradually reduces, the space gas pressure increases, and the gas between the blades is discharged from the disc exhaust port when the pressure is higher than the exhaust port pressure. In this way, whenever the impeller rotates one week, the space between the blades sucks and exhausts once. Many spaces work continuously, and the pump continuously sucks or presses gas.two-stage-high-pressure-rotary-vane-vacuum-pump-for-air-bleed

Because in the working process, work produces heat, which will heat the working water ring, and some water and gas are discharged together. Therefore, in the working process, it is necessary to continuously supply water to 2BV vacuum pump to cool and supplement the water consumed in the pump, so as to meet the working requirements of the pump.

When the gas discharged from the pump is no longer used, there is a gas-water separator connected to the exhaust port of the 2BV vacuum pump. After the exhaust gas and some water are discharged into the gas-water separator, the gas is separated from the exhaust pipe, and the remaining water is supplied to the pump through the return pipe for continued use. With the extension of working time, the temperature of working water will continue to rise. At this time, cold water should be supplied from the water supply pipe to reduce the temperature of working water and ensure that the pump can meet the required technical requirements and performance indicators.high-vacuum-turbomolecular-vacuum-pump-for-CVD-PVD-system-vacuum-measurement

The correct operation of 2BV vacuum pump is what we want to pay most attention to, not only if the method is affected, then the equipment will also cause the corresponding failure, which is very unfavorable for our use, so I hope you can grasp its working principle and improve the efficiency of work in time while operating correctly.induction-melting
