近年来,我区旱涝灾害交替发生,在抗旱排涝的紧急关头,由于机泵来源广,型号杂,因此,机泵不配套的情况经常出现,主要是水泵扬程大于实际需要太多,白白浪费油或电。如何解决这个问题呢? 解决这个问题并不难,只要将水泵降低转速使用就可以使水泵扬程降低到需要值,节约动力。水泵转速应该降到多少呢?水泵降速后流量、扬程、轴功率又将降到多少呢?
In recent years, flood and drought disasters in our district occurred alternately. At the critical moment of drought and waterlogging, due to the wide range of pump sources and miscellaneous models, it is not always the case that pump pumps are not equipped. The main problems are: Oil or electricity. How to solve this problem? Solve this problem is not difficult, as long as the pump speed can be used to reduce the pump head to the desired value, saving power. Pump speed should be reduced to how much? After the pump speed flow, head, shaft power in turn how much it?
