Narendrabhai Luhar developed a valve to pump out water from the tube well by `Pichkari' (creating suction and pressure) system with the help of diesel engines. This is useful for lifiting the water even from 300 to 1000 feet without using electricity. He is manufacturing this valve since 1988 and people from different parts of the state have been purchasing it for last five years. Operation of the Valve: Two lister type of diesel engines having 5-6 hp (Horse power) capacity are placed in opposite direction and a pulley of 12' (inch) diameter fitted to each engine. Narendrabhai removes some of the spare parts of the engine like push rod, shaftin, ideal gear box, springs of air valve and automatizer and replaces them with special kind of stud and visor to fit the new air valve in such a way that it can exhaust air with a force of compressor machine. A pipe of 1.5' diameter is fitted at the outlet of air. This air pipe is inserted in tube well up to the bottom of the discharge pipe. The discharge pipe which is inserted in the tube well is sepcially designed in such a fashion that bottom remains broader and gradually it becomes narrow as it goes upward. At the bottom, 4' diameter of the pipe is kept for first 2' (feet) height. Later on, gradually, it's diameter is reduced by half inch at every 2-3' height of pipe till it get's final diameter of 2.5'. The pipe of 2.5' in diameter continues into the ground water. This design is so created as to create pressure at bottom so that water moves up in the pipe. The air pipe having 1.5' diameter and connected to air valve is inserted in the broader pipe at the bottom. The length of the inserted air pipe in the discharge assembly is kept approximately 1 to 2 feet. This entire broader portion remains dipped in the free water of tube well at bottom. However, it is kept 7-10 feet above the bottom of the well. When diesel engines start working, air blows with pressure and goes to the bottom of the discharge pipe through air pipe. Because of the air pressure at the bottom water moves in upward direction. This valve regulates the flow of air in one direction so that air cannot move backward. Hence, the pressure remains created at the bottom. Narendrabhai has sold about 260 valves in different districts of Gujarat. Farmers who are using it, say that it does not provide continuous flow. After having feed back, he is doing research to get continuous flow. He has solved the problem but cost increases because of anothre set of costlier engine. Now, he is working on to reduce the price for getting continuous flow. |
