DE SAGUN, ERWIN RAFAEL. Don Severino Agricultural College, Indang, Cavite, April 1997. "DEVELOPMENT AND EVALUATION OF A WATERWHEEL-OPERATED PISTON PUMP" Adviser: Engr. Leyma L. Cero
The study, "Development and Evaluation of a Waterwheel—Operated Piston Pump”, was conducted at the Don Severino Agricultural College from January to March 1997. It specifically aimed to design a piston pump which would suit the rural conditions, to know the optimum operating conditions of the pump, and to evaluate the efficiency of the machine in lifting water.
The waterwheel—operated piston pump has three components, namely: the wheel assembly, the chain and sprocket assembly , and the pump assembly . The wheel
assembly is the rotating part which serves as the source of power of the machine. The chain and sprocket assembly are composed of two sprockets of different sizes that transmit power from the bigger sprocket to the other by means of chains. The pump assembly provides the pumping action and pressure necessary to lift water to higher elevation.
The waterwheel—operated piston pump operated at a minimum flow of water with 4.54 lps and tested to maximum flow of water of 45.38 lps for a constant height of fall of 1.2 m (4 ft). The maximum delivery was obtained at 45.38 Ips water flow with 41.80 1pm delivery with a lift of 121.92 cm On the other hand, the lowest delivery of 1.60 1 pm was observed at 4.54 Ips water flow with a lift of 183.00 cm (6 ft). The highest and lowest efficiencies were observed at 45.38 Ips water flow with 121.92 cm (4 ft) liftand 18.15 Ips water flow with 396.24 cm (13 ft) lift, with values of 81.48 percent and 26.30 percent, respectively.
The efficiency decreased as the lift increased and it increased as the flow of water increased. It was also observed that the lift increases as the water flow increases. The velocity of the waterwheel determines the amount of water delivered the developed waterwheel operated piston pump had higher overall efficiency compared to the hydraulic ram developed by Babaan (1992).
The total cost of the developed waterwheel—operated piston pump was P4, 404, 00. It was constructed from readily available materials. The total cost of the developed pistonpump implies that it is still economical as compared to commercial pumps. Also, it is easier to maintain, operate and replace parts which are readily available with least cost (oil rings and GI pipes, for instance). Thus, the developed waterwheel—operated piston pump is adaptable to rural areas where there is sufficient source of flowing/ falling water.
