Water Ring Vacuum Pump Structure Chart

Water-ring vacuum pump is a kind of pump product which connects pump and motor and works under water at the same time. It mainly consists of shaft, bearing frame, pump cover, impeller, pump seat, motor support, motor and other components. The structure of the sewer ring vacuum pump is introduced below.
The water ring vacuum pump adopts the structure of single-stage action. The pump is composed of pump body, impeller, front and rear cover (two pieces), front and rear distributor, shaft, front and rear bearing parts, valve plate parts, etc. The shaft is eccentrically installed in the pump body, the impeller and the shaft are interference fit, and the total clearance between the two ends of the pump is adjusted by the cushion between the pump body and the distributor. When assembling, the front end is positioned to determine the single-side clearance first. The clearance between the impeller and the distributor has a greater influence on the gas leakage (leakage from the exhaust chamber to the suction chamber). Therefore, assembly must be guaranteed. For pumps whose impeller diameter is greater than 500 mm, the one-sided clearance should be controlled between 0.25 and 0.35, and the total clearance at both ends should be between 0.5 and 0.7.vacuum pumps classification

The pump chamber is provided with an inlet and an outlet, and a group of blades are arranged between the inlet and the outlet. The rotating shaft of the blades is a motor shaft in the pump body. A guide plate is arranged at the outlet position of the pump chamber. One side of the guide plate is pivoted on the guide shaft, and the guide shaft and the motor axis are on the same straight line. The distance between the guide shaft and the motor axis is slightly larger than the rotating radius of the blade, and the rotating angle of the guide plate is limited by the pump chamber. When the pump works, the impulse of water flow will make the guide plate swing to one side and seal the side of the pump chamber. Under the blockage of the guide plate, part of the water flow driven by the blade rotation will not rotate repeatedly with the blade in the pump chamber, but will be effectively discharged from the drainage port, so that the efficiency of the pump can be effectively improved.

The filler is packed in two end caps and the sealing liquid enters the packing chamber through the hole in the end cap to cool the filler and enhance the sealing effect.single stage rotary vane vacuum pump

When the mechanical seal is used, the mechanical seal is installed in the packing chamber, and the packing cover is replaced by the mechanical seal cover. The front and rear distributors are equipped with suction and exhaust crescent holes and elliptical exhaust holes, and valve plate components. The function of the valve plate is to discharge the gas before the crescent outlet when the gas pressure between impeller blades reaches the exhaust pressure, thus reducing the consumption of increasing power due to excessive gas pressure.roots vacuum pump low vacuum degree treatment reasons

The water ring vacuum pump adopts a unique impeller structure with single or double blades, which greatly improves the trafficability of sewage. It can effectively pass through five times the diameter of the pump and solid particles with a diameter of about 50% of the diameter of the pump. The mechanical seal uses a new type of hard and corrosion-resistant tungsten carbide material, which makes it run in oil chamber for a long time, and can make the pump run safely and continuously for more than 8000 hours.
