如何正確選擇多吸頭排污泵

多吸頭排污泵是一種常用的排污泵，它的特點是每臺泵有4個吸水頭，分布在泵坑的中央和各個角落，因而吸頭備用率高，吸水范圍大，泵坑沉積少。在選擇多吸頭排污泵時，需要考慮以下幾個方面：1. 流量應按生活排水設計秒流量選定；當有排水量調節時，可按生活排水最大小時流量選定。2. 揚程應按照系統水力計算書要求選擇。3. 多吸頭排污泵的流量、揚程、轉速等參數應與使用條件相符。4. 多吸頭排污泵的結構應符合使用要求。5. 多吸頭排污泵的材質應符合使用要求  。

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.
