山西省是多山且贫水的省份。很多县城的供水,由于水源水量有限,提升高度较大,地形复杂等因素,使输水管道造成很大的水锤破坏力。为了避免各种破坏力,在过去的输提水工程中,往往采用多级提水的方式。多级提水存在着投资大,使用管理不方便,维护费用高,漏水量大等缺点。一九八五年我院在汾西县提水工程的设计中,采用了超高压一级提水的办法,获得较佳效果。工程设计成果简介如下:
Shanxi Province is a mountainous and water-poor province. The water supply in many counties has caused water hammers to cause great damage to water hammer due to the limited water source, high lifting height, and complex terrain. In order to avoid all sorts of destructive forces, in the past, water lifting projects often used multi-stage water lifting. There are many disadvantages such as large investment, inconvenient use and management, high maintenance cost and large amount of water leakage. In 1985, in the design of the water lifting project in Qianxi County, our institute adopted the ultra-high-pressure water-lifting method to obtain better results. The engineering design results are as follows:
