2BV vacuum pump is a common single-stage pump with a common structure-machine pump coaxial. When we are using it, we will get everyone's attention because of the overall advantage. Let me introduce you to the advantages of using it. .
The seal of the 2BV vacuum pump is mechanically sealed, and the mechanical seal is installed between the impeller and the pump body. The gap between the impeller and the pump body is determined by a mechanical seal. A disc is mounted on the vacuum pump cover, and the disc is provided with suction and exhaust holes and a flexible exhaust valve piece. The function of the flexible valve piece is that when the gas pressure between the impeller blades reaches the exhaust pressure, before the exhaust port By discharging the gas, the power consumed due to excessive gas pressure is reduced, thereby reducing the rate consumption.
The 2BV vacuum pump consists of pump cover, pump body, disc, impeller, mechanical seal, motor and other components. The intake pipe exhaust pipe is connected to the pump chamber through an air suction hole and a vent hole on a disc mounted on the pump cover, and the shaft is eccentrically installed in the pump body, and the impeller is fixed on the shaft by a flat key, and both ends of the vacuum pump are The gap is adjusted by the pad between the pump body and the disk.
The gap between the 2BV vacuum pump impeller and the disc on the pump cover is adjusted by the pad between the disc and the pump body. The gap between the end faces of the impeller and the disc on the pump cover determines the gas in the pump chamber from the intake port to The amount of loss in the flow of the exhaust port and its ultimate pressure.
