What are the common types of sewage submersible pumps?

Sewage Submersible Pump The pump unit and drain connection must be sealed, the entire weight of the motor must be borne by the pump's drain elbow, and any part of the motor must not come into direct contact with the pump pit floor, nor should the motor be placed on the pump Pit floor support above. Sewage submersible pump is a use of special equipment, the common type of sewage submersible pump understanding, the product of great significance. What are the common types of sewage submersible pumps? The following describes several common types of sewage submersible pumps: 1, swirl impeller sewage submersible pump: mainly due to some or all of the impeller shrunk pressure water chamber runner. Therefore, no blockage performance is good, through the ability of the particles and long fibers can be stronger. Particles in the pressurized water chamber movement by impeller rotation generated by the eddy movement, the suspended particles do not produce energy itself, but in the flow and liquid exchange of energy. During the movement, suspended particles or long fibers are not in contact with the blade, the blade is more wear and tear less, there is no increase in the gap due to abrasion, long-term operation will not cause serious loss of efficiency title, the use of the Type impeller pumps are suitable for pumping media containing large particles and long fibers. From the performance point of view, the impeller efficiency is low, only about 70% of ordinary closed impeller, lift curve is relatively flat. 2, Closed impeller sewage submersible pump: This type of submersible pump impeller higher efficiency. And in the long run the situation is relatively stable, using the type of impeller pump axial force is small, and can be set in the front and rear cover Vice blades. The auxiliary blades on the front cover reduce vortex loss at the impeller inlet and wear of the particles on the seal ring. The auxiliary blades on the rear cover not only act as a balanced axial force but also prevent the suspended particles from entering the mechanical seal cavity to protect the mechanical seal. 3, runner-style impeller sewage submersible pump: Impeller runner is a from the import to export a tortuous runner. It is therefore suitable for pumping media containing large particles and long fibers. Good anti-blocking. From the performance point of view, the type of high efficiency impeller and ordinary closed impeller or less, but the type of impeller pump head curve is steep drop. The power curve is relatively stable, not easy to produce the title of super power, but this type of impeller cavitation performance is not as good as the ordinary closed impeller, especially suitable for pressure on the import pump. 4, Spiral centrifugal impeller sewage submersible pump: This type of impeller blades for the twisted helical blades in the tapered hub body from the suction inlet along the axial extension. This type of impeller pump also has the role of volumetric pumps and centrifugal pumps, suspended particles flow through the leaves in the period, does not hit any part of the pump, so good non-destructive. Damage to conveyors is small. Due to the spiraling action and the high permeability of the suspended particles, pumps using this type of impeller are suitable for pumping media containing large particles and long fibers, as well as highly concentrated media. In the transmission of media damage has a strict request occasions have obvious characteristics. Through the introduction of 4 above, we can understand that the sewage submersible pump family is huge, and every member of the family is full of personality. It can be said that with so many powerful family forces, the future of sewage submersible pump will surely be bright. However, in the face of market pressure, it needs further research and innovation.
