- Abstract:
- When submersible axial flow pump is applied in sewage treatment plants, its impeller is often wrapped by garbage and other debris in operation, leading to the problem that the impeller is locked and unable to run. In addition, it significantly increases the pump maintenance and cleaning workload and raises the operation cost. The submersible axial flow pump in the intake pump house of Lianghe underground sewage treatment plant in Jiujiang could not be directly observed and was often blocked and wound before the transformation, leading to failure to operate. Therefore, two schemes, namely removing the wear ring and replacing a new volute with garbage release groove, were proposed to solve the problems. In two months after the transformation, the pumps transformed by the two schemes were not blocked. The flow rate and energy consumption of the two schemes before and after transformation was compared and analyzed. Both the two schemes had different degrees of flow rate attenuation phenomenon, and the energy consumption of replacing the volute with garbage release groove was less.
