1.取消底阀，底阀阻力系数较大，一般可降低扬程1.5米左右。取消底阀以后水泵的效率会显著提高。若在出水管口装上一拍门，再用黄油封住填料盒，这样，停泵后再次启动时就不必充水。 2.取消闸阀和逆止阀，闸阀和逆止阀阻力系数比较大，闸阀的作用是为了调节水量，但农用泵的水量不必调节，因此可以省去。逆止阀的作用是防止水倒流，有了拍门后，也就不需要逆止阀了。 3.将水泵斜装(或将水泵蜗壳转向)这样可使进出水管直对进出水池，以减少弯头。 4.减少管路滤网损失使用O.8毫米钢丝代替滤网，使过水断面空隙率增大而减少耗电。 5.进水管要有足够的淹没深度当淹没深度不够时，水会产生游涡，将空气带入水泵，降低泵的效率。枯水期进水管的淹没深度应大于0.5米。 6.避免“高射炮”式出水法由于出水管高于出水池的水面，扬程损失大，管口流出的水会在侧壁上产生反射波，增加出水口的压力，影响出水。 7.选用经济管径水管的阻力损失与管径的5次方成反比，水管直径越小，阻力就越大。出水管的经济管径为水泵流量开方后的O.65-O.8倍，进水管的经济管径为水流量开方后的0.8-0.92倍。 8.及时xx流道堵塞物如果有杂质堵塞进出水管、叶轮或导流壳流道，将使水量减少。 9.提高皮带传动效串注意皮带的紧边与松边的传动包角，使用中也不要将宽皮带改为窄皮带，并注意皮带的松紧度。 10.换口环，调整轴向间隙叶轮口环间隙大，容积效率下降。因此要定期检查口环间隙。轴向间隙的数值，应根据出厂说明书规定调整。

1. Abolished at the end of valve, valve at the end of a larger drag coefficient is generally around 1.5 m to reduce lift. Abolished at the end of valve after the pump efficiency will be improved significantly. If the outlet pipe fitted with a mouth-door, and then sealed packing butter boxes, so that when you start again after stopping pumps do not have to water-filled. 2. Cancellation valve and check valve, gate valve and check valve resistance coefficient relatively large, the role of the valve is to regulate water, but do not have to adjust agricultural water pump, it can save. The role of the check valve to prevent water backflow, with the film door, also do not need a check valve. 3. The pump oblique loading (or pump volute shift) This will allow direct access to water entering and leaving the pool to reduce the elbow. 4. Reduce the loss of the use of pipe filters O.8 mm steel wire instead of filter, so that the increase of cross section porosity and reducing consumption. 5. Into the water sufficient submergence depth when submerged deep enough, the water will produce vortex tour, will air into the pump, reducing pump efficiency. The submerged into the water during the dry season should be more than 0.5 m deep. 6. To avoid "gun" type of water outlet pipe above the law out of the pool because of the water, head loss of large orifice in the wall of water flowing to generate reflected waves increase the outlet pressure on the water. 7. Selection of economic pipe diameter water resistance to 5-th power loss and the diameter is inversely proportional to the smaller diameter pipes, the greater the resistance. Outlet pipe diameter of pump flow rate of the economy after the O.65-O.8 prescribing times, the economic diameter pipe into the water flow after the 0.8-0.92 times the square root. 8. Promptly remove material blocking flow channel blocked if there are impurities out of water pipes, impellers or deflector shell flow channel, would reduce the amount of water. 9. To improve efficiency belt transmission belt tight strings note that while the transmission side and the loose angle, do not want to use a wide belt into a narrow belt, and pay attention to belt tightness. 10. For Sandy Bay, Sandy Bay impeller clearance adjustment of axial gap large volume reduction of efficiency. Therefore, I regularly check the ring gap. The value of axial clearance should be adjusted according to the provisions of the factory specifications.
