If you spray oil outward, you should stop and check immediaby. The purchase of mechanical seals at different prices has a significant impact on their quality. Take quality control measures mechanical seal before leaving the factory must do sealing perbance test, and have a certificate. Mechanical seal after long-term operation, so that the dynamic ring and static ring wear, spring and shaft rust wear, sealant ring wear, aging, debation, etc., can cause sealing leakage, must repair or replace new parts. The sealing surface of the dynamic ring and static ring shall not have cracks, corners, scratches, hemp points, flying edges and partial grinding, scratches, hemp points can not run through the entire sealing end surface. If the fixed static and dynamic ring is used, the height of the convex of the static and dynamic ring is not less than 3mm, and the height of a single convex is not less than lmm, so as not to affect the heat dissipation. 3 Dynamic ring After installation should be guaranteed to move flexibly on the shaft, the dynamic ring pressure on the spring should be able to bounce back freely, to maintain the vertical and parallel of the static and dynamic ring. Reasonable selection of medium-open pump, is to consider the pump unit and pumping station investment and operating costs, such as comprehensive technical and economic indicators.

Thus the centrifugal force is generated, under the b of centrifugal force, the liquid is dumped along the Blade Runner to the impeller outlet, and the liquid is collected and fed into the discharge tube through the worm shell. The liquid obtains energy from the impeller, increasing the pressure energy and speed energy, and relies on this energy to transport the liquid to the place of work. When an impeller does not allow the liquid to obtain sufficient energy, multiple impellers can be used in series or in parallel to work on the fluid. At the same time that the liquid is dumped to the impeller outlet, a low pressure is bed at the center of the impeller Inlet, and the pressure difference is generated between the liquid in the suction tank and the center of the impeller, and the liquid in the suction tank is continuously operated into the impeller under the b of this pressure difference. In this way, the impeller in the rotation process, one side of the constant liquid, while constantly giving the liquid with a certain amount of energy, the liquid discharge, so that the centrifugal pump work continuously. The medium-open pump is mainly composed of pump body, pump cover, sealing ring and rotor parts. Rotor parts are mainly composed of shafts and impeller mounted on the shaft, impeller retaining sleeve.
