随着城市人民生活水平的提高,对城市污水处理要求不断提高,城市污水泵站数量增速很快,运营管理单位的管理难度随着增高。在污水泵站的设计施工中,为了达到最大的管路效率,一般采用拍门断流。但采用拍门断流时,由于突然断电,使出水管内的流体倒泄,机组反转而引发出的一些问题,引发了一些思考。 With the improvement of people's living standard in urban areas, the requirements for urban sewage treatment are continuously increasing, and the number of urban sewage pumping stations is increasing rapidly. As a result, the management difficulty of the operation management units increases with each passing day. In the sewage pump station design and construction, in order to achieve the maximum pipeline efficiency, the general cut off the door. However, when the door is shut off, some problems caused by the reversal of the unit due to a sudden power failure cause the fluid in the outlet pipe to be drained off, which triggers some reflections.
