High-pressure pipeline long-distance water conveying device and water conveying method
The high-pressure pipeline long-distance water conveying device comprises a pump station water outlet pool and a storage tank, the upper end of the pump station water outlet pool communicates with the upper end of the storage tank through a water conveying pipeline, the lower end of the pump station water outlet pool communicates with the lower end of the storage tank through a pressure relief pipeline, and the storage tank communicates with a high-pressure pipeline used for farm irrigation; a first inlet valve, a first check valve and a self-priming pump are sequentially arranged on the water conveying pipeline, a second inlet valve, a first high-pressure water pump and a second check valve are sequentially arranged on the pressure relief pipeline, and a pressure transmitter, a third check valve, a second high-pressure water pump, a flow controller, a flow sensor and an outlet valve are sequentially arranged on the high-pressure pipeline. The first high-pressure water pump and the self-priming pump are adopted correspondingly to different pressures, so that the water delivery flow speed is increased, the flow controller is arranged, water is continuously output in the high-pressure pipeline through the second high-pressure water pump in a constant flow mode and is not prone to being affected, and the overall stability is improved while the efficiency is improved.
发明提供一种高压管道长距离输水装置及输水方法，包括泵站出水池和储蓄罐，泵站出水池和储蓄罐的上端通过输水管道连通，泵站出水池和储蓄罐的下端通过泄压管道连通，储蓄罐上连通有用于农田灌溉的高压管道；输水管道上依次设有第一入口阀、第一止回阀和自吸泵，泄压管道上依次设有第二入口阀、第一高压水泵和第二止回阀，高压管道上依次设有压力变送器、第三止回阀、第二高压水泵、流量控制器、流量传感器和出口阀；对应不同压力分别采用第一高压水泵和自吸泵，从而提高输水流速，通过设置流量控制器，从而使得水在高压管道内经第二高压水泵持续恒流输出不易受影响，在提高效率的同时还提高了整体稳定性。
