如何正确选择多吸头排污泵

多吸头排污泵是一种常用的排污泵，它的特点是每台泵有4个吸水头，分布在泵坑的中央和各个角落，因而吸头备用率高，吸水范围大，泵坑沉积少。在选择多吸头排污泵时，需要考虑以下几个方面：1. 流量应按生活排水设计秒流量选定；当有排水量调节时，可按生活排水最大小时流量选定。2. 扬程应按照系统水力计算书要求选择。3. 多吸头排污泵的流量、扬程、转速等参数应与使用条件相符。4. 多吸头排污泵的结构应符合使用要求。5. 多吸头排污泵的材质应符合使用要求  。

How to correctly select a multi suction sewage pump

Multi suction sewage pump is a commonly used sewage pump, characterized by four suction heads per pump, distributed in the center and various corners of the pump pit. Therefore, the standby rate of the suction head is high, the suction range is large, and the pump pit sedimentation is less. When selecting a multi suction sewage pump, the following aspects need to be considered: 1 The flow rate should be selected according to the design second flow rate of domestic drainage; When there is drainage adjustment, it can be selected based on the maximum hourly flow rate of domestic drainage. 2. The head should be selected according to the requirements of the system hydraulic calculation sheet. 3. The flow rate, head, speed and other parameters of the multi suction sewage pump should be consistent with the operating conditions. 4. The structure of the multi suction sewage pump should meet the usage requirements. 5. The material of the multi suction sewage pump should meet the usage requirements.
