The strategy on piping transportation water irrigation in channel irrigation district in Shaanxi Province;

In view of the fact that the availability of well water and the electric energy comprehensive utilization rate are low in surface irrigation under low pressure pipeline of water delivery; a new idea of applying frequency control technology to a low pressure pipeline was proposed in this paper, which allows the pump to operate under the condition of constant discharge at varied pressures.

As the most widely used water-saving irrigation mode, pipeline irrigation has grown rapidly in the last two decades, also it has a wide foreground in the future.
