离心式水泵流量测试结果“偏大”的分析

离心式水泵是井工开采矿山必不可少的设备之一,水泵型号选择主要是根据矿井正常涌水量、最大涌水量以及井下水泵房到出水口的高度来确定。有时因型号选择不正确将导致水泵流量"偏大",电动机运行功率超过其额定功率,电动机有可能被烧毁。工作中可常利用离心式水泵的特性曲线来分析流量与扬程以及流量与电动机运行功率的关系。

Centrifugal Pump Flow Test Results too large Analysis

Centrifugal pump is essential for underground mining equipment,mine is one of the main pump model selection is based on the normal discharge of mine,the largest underground water inflow and pump house to determine the height of the outlet.Sometimes due to incorrect model selection will result in pump flow too large,the motor operating power than its rated power,the motor may be burned.Work can often use centrifugal pump characteristic curve to analyze traffic flow and head,and the relationship between power...
