| Abstract | A widespread need exists for a low-cost, low-lift pump for supplying irrigation water to rice fields, This arises because, although primary irrigation systems may exist, secondary distribution systems are often inadequate, Also, in countries of Southeast Asia such as Thailand and Vietnam it is desirable to grow 2nd or 3rd crops of rice, which grow out of the normal rainy season, the paddy field, At such times water must be pumped to reach A complete solar pumping system has been designed at AIT comprising a diaphragm pump, Solar collector, condenser and return feed pump. pump operates on a Rankine vapour cycle system, using freon 113 as a working fluid, The This research was concerned with studying the characteristics of the diaphragm pump component only, using compressed air as a pressure source. The test results showed that the pump had a maximum efficiency about 14 percent, This occurred when the pump was operated at 0.7 kg/cm inlet air pressure, with 4 meter lift and delivery 3.28 litres/min. The pump discharge was found to depend primarily upon the discharge head; its output feel to zero when the water discharge pressure was equal to that of the actuating vapour, |
