water ring vacuum pump structural componentsWater ring vacuum pump structure description: Water ring vacuum pump is composed of pump body, front and rear end cover, impeller, shaft and other parts. And parts and components are mutually complementary, and one less water ring vacuum pump will be paralyzed, so let's take a look at the detailed structure of the water ring vacuum pump:The intake pipe and the exhaust pipe are connected to the pump cavity through the suction hole and the exhaust hole on the disk mounted on the end cover. The impeller of the water ring vacuum pump is fixed on the shaft with a key and is eccentrically installed in the pump body. The total gap between the two ends of the pump is adjusted by the pad between the pump body and the disc. The gap between the impeller and the front and rear discs is adjusted by the impeller pushing the impeller. The gap at both ends is guaranteed to be uniform. The shaft and the impeller are interference fits, and this clearance is determined when the front end is positioned. The clearance between the two end surfaces of the impeller and the front and rear disks determines the magnitude of the gas loss in the pump cavity from the inlet to the exhaust port and its ultimate pressure.The water ring vacuum pump packing is installed in the two ends of the cap, and the sealing water enters the packing through the small holes in the end cap, cooling the packing and strengthening the sealing effect. The supplementary water required for the impeller to form a water ring is supplied by the water supply pipe, which can also be connected to the steam-water separator to circulate water. If the mechanical seal is used as the seal type, the mechanical seal is installed in the filling cavity, and no filler is needed. The filler gland is replaced with a mechanical seal gland, and the rest of the structure is the same.The water ring vacuum pump bearing is fixed on the shaft by a round nut. A disc is installed on the end cover, and the disc is provided with suction and exhaust holes and a rubber ball valve. The function of the rubber ball valve is that when the gas pressure between the impeller blades reaches the exhaust pressure, the gas is discharged before the exhaust port, which feeds the power consumed by the excessive gas pressure and reduces the power consumption.
