农用水泵常因功率过大耗能多，作业成本高而缩短其使用寿命。产生原因及解决方法如下。1选型不当。高扬程水泵如当作低扬程水泵安装使用，使水泵流量增大，功耗过大。应更换或选用合适的水泵，或关小出水管路上的闸阀。2．转速增高。在选配水泵动力时，动力机转速比规定转速高 Agricultural pumps often due to excessive power consumption, high operating costs and shorten its service life. The causes and solutions are as follows. 1 improper selection. High-lift pumps such as low-lift pump installed as the use of the pump to increase traffic, power consumption is too large. Should be replaced or use a suitable pump, or off the gate valve on the water line. 2. Increased speed. In the optional pump power, the power machine speed higher than the specified speed
