1) low pressure irrigation pipe
低压灌溉管道
3) surface irrigation under low pressure pipeline of water delivery
低压管道输水灌溉
1.
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.
