摘要:
潜水轴流泵用于污水处理厂时，在实际运行中经常发生泵叶轮被垃圾等杂物缠绕，导致叶轮抱死不能运行的问题，使泵维护清理垃圾工作量大幅增加且抬高了运维成本。九江市两河地下污水处理厂进水泵房潜水轴流泵，改造前无法直接观测其运行状态，且经常被堵塞缠绕致其无法运行，因此采取了拆除耐磨环及更换带垃圾释放凹槽蜗壳两种方案进行改造。在改造后的两个月内，采用两种方案改造的水泵均未发生堵塞情况。进一步对改造前、后的流量及能耗进行了对比分析，发现两方案都出现不同程度的流量衰减现象，而更换带垃圾释放凹槽蜗壳的能耗更少。
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.
