渣漿泵的運(yùn)行與調(diào)節(jié)流量揚(yáng)程
第一節(jié)裝置揚(yáng)程特性曲線及 工作點(diǎn)
一、 裝置揚(yáng)程特性曲線(或稱(chēng)管路特性曲線)
在第二章式(2-4')中，裝置揚(yáng)程
Hc=Hz+ P2-P1/ pg + hw
式中 Hz----出水池液面 與進(jìn)水池液面的位置高差，當(dāng)泵安裝確定后它是 一個(gè)定數(shù):
P2、P1---出水面、 進(jìn)水面上的壓力，當(dāng)裝置確定后，P2 、P也就確定了， 也是一個(gè)
定數(shù);
hw---進(jìn)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
