Introduction of 2BE vacuum pump

The vacuum pump is a single-stage single-action structure pump with a pump cover. impeller. Disc pump body. axis, etc. Next, I will introduce to you in detail: The impeller and shaft of the vacuum pump are thermally fitted with an interference fit. The gap between the impeller and the end face is adjusted by the positioning bearing. This gap determines the size and loss of gas in the pump cavity when it flows from the air inlet to the exhaust port. Extreme pressure.
The packing is installed in the two pump covers. Sealing water enters the packing chamber through the holes in the pump cover to cool the packing and enhance the sealing effect.
When the pump has a mechanical seal, replace the packing gland with a mechanical seal gland.
Valve plates are installed on the front and rear distribution plates. The function of the valve plate is to discharge the gas in front of the exhaust port when the pressure between the impeller blades reaches the exhaust pressure, thereby reducing the power consumption caused by excessive gas pressure.
The above is an introduction to the vacuum pump. At the same time, the editor reminds: Since the pump compresses the gas in an isothermal state during the working process, it can be pumped and flammable. Explosive gases can also be used to pump corrosive gases or use corrosive liquids as working fluids by changing the structural materials.
