渣漿泵的運行與調節(jié)流量揚程

第一節(jié)裝置揚程特性曲線及 工作點
一、 裝置揚程特性曲線(或稱管路特性曲線)

在第二章式(2-4')中，裝置揚程

Hc=Hz+ P2-P1/ pg + hw
式中   Hz----出水池液面 與進水池液面的位置高差，當泵安裝確定后它是 一個定數(shù):

P2、P1---出水面、 進水面上的壓力，當裝置確定后，P2 、P也就確定了， 也是一個
定數(shù);
     hw---進出管路 系統(tǒng)的總水力損失。 渣漿泵廠家

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
