Inventing water pumps

The use of water power to produce electricity for living and production has become commonplace. But with teacher Tran Dinh Huan, who used water instead of fuel to pump water on high hills, this is a bold idea.

On the first day of February, 2003, standing beside a small hydro-electric plant built by China, Tran Dinh Huan, a teacher at the Kon Tum Education and Training Department, Why do not you make a water pump to reduce the cost of watering your coffee when you just add a bulldozer and a strap?

Thought to do, since that day he started work. First of all, to get the technical specifications for the production and processing, he came down to Ho Chi Minh City to buy hydraulic training materials. When he is free, he goes to the Internet to collect more material.

From the idea, then study into the shape of the machine was difficult, to make the machine from the design drawings again more difficult. Holding the drawings on hand to bring out the product, everyone does not believe he will succeed. Been a mechanic is the old pupil help, after more than a week removed, inserted, sharpened, grinding ... his pump is complete. Excited to forget the whole meal, he immediately brought the machine into the field and test. A stream of water like a tornado spilled over a dozen meters, causing him and the young man to work with him.

According to calculations by Mr. Huan, this water-powered machine is located at a difference of 2 meters in waterfall, with a 30 cm diameter inlet, pumping water 500 m away in a 5 cm diameter pipe and pumping over 20 m. With the above indicators, one day pumped 400 m3 to serve irrigation (equivalent to 22 hp diesel oil pump).

Tay Nguyen is the focus of coffee, pepper and dense river systems with steep slopes relatively large, suitable for using this type of pump. To own a water pump, each family just spent 1.5 million. The weight of the machine is only about 35 kg, simple structure, easy to transport and repair.
