泵出流量、扬程
Reply #42020-06-24
请教各位:离心泵扬程、流量、出口压力三者关系,另外泵的额定电流与保护电流的关系
Reply #52020-06-24
扬程和流量是根据工艺要求选出来的,泵确定后,流量和扬程是相关的,当扬程远大于管阻力时,流量变大,电机容易超电流烧毁,扬程小于管阻力时,流量变小甚至是送不到指定位置。出口压力一般等于扬程-测量点的管阻力。额定电流是指在正常运行时的额定功率对应的电流,保护电流一般是要大于6-7倍(启动电流)的额定电流。你的的问题问的很杂

简单的说,流量扬程关系看性能曲线,出口压力=入口压力×扬程×比重,超载热保护继电器(1.1-1.2倍额定电流),并且应避免启动瞬间电流
