泵组合
Examples
- Technical specification for fuel injection pump assembly of marine disel engines
船用柴油机喷油泵总成技术条件 - 24 months for pumping assembly
24个月主要部件泵 - Flow circulation and deviation could be eliminated by enlarging the back guide blade outlet incidence , and pump assembly efficiency could be increased by 1 . 6 ~ 2 . 4 percentage points
增大后导叶出口安放角，可以消除环量和偏流，提高泵装置效率1 . 6 ~ 2 . 4个百分点。 - Results indicate that flow deviation in discharge passage is formed by co - action of pump outflow circulation and secondary flows in outflow curved pipe , hydraulic loss of discharge passage increases and pump assembly efficiency decreases because of flow deviation
结果表明：水泵出流环量和出水弯管二次流共同作用形成了出水流道偏流，偏流使出水流道水力损失增大，泵装置效率下降。
