The characteristic of this installation compared with toe technologys now availatble is as follows; it needs no driving power, the structure of which is very simple; the water-supply height is not restricted for any factors within the most scops. Using H-O internal storing high-pressure gas pope as the pessure device, we can at least make the water-supply height to be 403.2 metres. If we use 16MPa mine filter press, transfering water freeboard can be very, and the height of weater-supply will be at least 1,644 meters, If the strenth of alloyed steel is desighed to be at least 50kg per square millimeters, the water-supply height will reach 50,565.6 metres.

该装置与现有技术相比其特点是：结构简单，不用动力，且上水高度在较大范围内不受任何条件的限制，采用H－0型内贮式高压气管作加压工具，从而使上水高度最少为403.2米，如果使用16MPa矿压机便可实现超高输水，其上水高度最少为1644米，按照合金钢强度最低50千克力／平方毫米设计，该装置的上水高度最少可达到50565.6米。
