Development prospects of large sewage pumps
QW (WQ) type non-blocking submersible sewage pump is a new generation of pump products developed on the basis of introducing foreign advanced technology and combining the characteristics of domestic water pumps. It has remarkable energy saving effect, anti-winding, no clogging, automatic installation and Features such as automatic control. It has a unique effect in discharging solid particles and long-fiber waste.
This series of sewage pumps uses a unique impeller structure and a new mechanical seal to efficiently transport solids and long fibers. Compared with the conventional impeller, the impeller is in the form of a single flow channel or a double flow channel. It is similar to a curved pipe of the same cross-section. It has very good over-flow and is equipped with a reasonable volute to make the pump efficient. High and impeller dynamic and static balance test, so that the pump has no vibration during operation.
