Performance evaluation of hydraulic ram by varying the weight and stroke length of waste valve

摘要

A hydraulic ram (50 mm X 25 mm) was designed, fabricated and installed using locally available pipes and fittings and with some components which could be easily made. Test was conducted by varying the stroke length and weight of waste valve. The study revealed that the efficiency of hydraulic ram increased with decrease in stroke length of waste valve. It was also found that there is a minimum weight of waste valve corresponding to a certain weight of delivery valve, at which the hydraulic ram functions satisfactorily. The operating range of hydraulic ram was found to decrease with decrease in the weight of waste valve.
