First, the application of the so-called hydrodynamic expeller expeller seal fluid power sealing technology means that the back near the rear of the pump impeller cover in the opposite direction to install a coaxial open impeller. When the pump is working, vice impeller rotates together with the pump shaft 150WQ180-20-18 pump impeller deputy liquid will rotate with the rotation of the liquid will produce an outward centrifugal force, the centrifugal force on the one hand against the flow of mechanical seals liquid, reducing the pressure of the mechanical seal. On the other hand to prevent the media of solid particles into the mechanical seal friction, the reduction of the mechanical seal grinding block wear and prolong its service life. But deputy impeller sealing effect 200WQ250-15-18., Also can play a role in reducing the axial force in the submersible sewage pump axial force is mainly composed of liquid pressure differential forces on the impeller and the rotating part composed of gravity, the direction of action of these two forces is the same, force is added by the two forces together. Impeller design editor to ensure the smooth passage of dirt, we must increase the width of the impeller flow surface for large pumps, can be double-blade, three-blade; for small pump, the single (double) in the form of the flow channel, which is similar bend in a section of the same size, but also had a very good flow properties. Avoid clogging the water at low speed may cause the wound. The unique design of the impeller 100WQ100-35-18., With reasonable cochlear room, making sewage paper, textiles, trash bags and other materials can be freely passed. Impeller through dynamic and static balance, so that the pump with load and no-load commissioning process not produce vibrations 150WQ180-20-18 submersible pumps, sewage pumps, sewage pumps supplied by Anguo Shi Yuan Pumps Limited.
