宜春市袁州区下浦乡农民易仕林，经多年的观察与实践，成功研制出一种不用油、不用电，通过水力推动的叶轮式活塞抽水机。它的主要特点有： (1)只要水源流动就是它的动力来源 (无需大江大河 )，水流落差在 0.4m以上就可带动抽水机运转。抽水扬程可高达 100m，并能同时发电 1～ Yichun City Yuanzhou District Pu Township farmers Yi Shilin, after years of observation and practice, successfully developed a no oil, no electricity, through the impetus to impeller piston pump. Its main features are: (1) As long as the flow of water is its source of power (no large river), the water drop in the 0.4m above can drive the pump. Pumping head can be as high as 100m, and can generate 1 ~ at the same time
