The test results have proved that the flow rate widely varied and the pump efficiency is high when the pump outlet line structure was altered and the outlet pressure was controlled in a special limit.

试验结果表明，改变泵出口管线结构，使泵出口压力在一定范围内工作时，流量变化大，而且泵效率较高，可以作为泵调整参数的一种手段；

Pump is the drainage and back into the groove of reasonable design, is a gear in the work under the minimum torque force, so the bearing load is small, wear small, pump with high efficiency.

输送皂角泵内有设计合理的泄油和回油槽，是齿轮在工作中承受的扭矩力最小，因此轴承负荷小，磨损小，泵效率高。
