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(diǎn)是每臺泵有4個(gè)吸水頭，分布在泵坑的中央和各個(gè)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(shí)，需要考慮以下幾個(gè)方面：1. 流量應(yīng)按生活排水設(shè)計(jì)秒流量選定；當(dāng)有排水量調(diào)節(jié)時(shí)，可按生活排水最大小時(shí)流量選定。2. 揚(yáng)程應(yīng)按照系統(tǒng)水力計(jì)算書要求選擇。3. 多吸頭排污泵的流量、揚(yáng)程、轉(zhuǎn)速等參數(shù)應(yīng)與使用條件相符。4. 多吸頭排污泵的結(jié)構(gòu)應(yīng)符合使用要求。5. 多吸頭排污泵的材質(zhì)應(yīng)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.
