扬程降低效率正大其实量不变轴功率加大
Reply #72019-02-16
流量---轴功率曲线根据比重增加值成比例规律提升,其他曲线不变。

N=密度*g*H*Q,密度增加轴功线性增加。其余曲线不变。

莫急,慢慢来,流量-扬程,流量-效率,流量-汽蚀余量这些都几乎是泵本身的固有属性,受外界影响小(除了粘度变化会有一些影响),而流量-轴功率是与介质比重直接相关的,轴功率会变大

流量-轴功率等比例变化,其他不变(粘度不变的话)
Reply #112019-02-16
离心泵的压头和流量均与液体的密度无关,有效功率和轴功率随密度的增加而增加,这是因为离心力及其所做的功与密度成正比,但效率和扬程与密度无关。

流量不变,扬程、效率降低,轴功率增大,汽蚀余量不变

介质比重变大,扬程减小、效率减小、汽蚀余量增大和轴功率不变

扬程降低,轴功率升高。
