渣浆泵的运行与调节流量扬程

第一节装置扬程特性曲线及 工作点
一、 装置扬程特性曲线(或称管路特性曲线)

在第二章式(2-4')中，装置扬程

Hc=Hz+ P2-P1/ pg + hw
式中   Hz----出水池液面 与进水池液面的位置高差，当泵安装确定后它是 一个定数:

P2、P1---出水面、 进水面上的压力，当装置确定后，P2 、P也就确定了， 也是一个
定数;
     hw---进出管路 系统的总水力损失。 渣浆泵厂家

Operation of slurry pump and regulating flow head

Section I head characteristic curve and working point of the device

I. device lift characteristic curve (or pipeline characteristic curve)

In formula (2-4 ') of Chapter II, the unit lift

Hc=Hz+ P2-P1/ pg + hw

In the formula, Hz is the height difference between the liquid level of the water outlet and the liquid level of the water inlet. When the pump is installed, it is a fixed number:

P2, P1 --- the pressure on the water outlet and water inlet. When the device is determined, P2 and P are also determined

Fixed number;

HW - total hydraulic loss of inlet and outlet pipeline system Slurry pump
