DEVELOPMENT OF HYDRAULIC WATER PUMPING DEVICE DEVELOPMENT OF HYDRAULIC WATER PUMPING DEVICE

Abstract

This thesis presents new development of hydraulic water pumping device, with necessary design equations and steps to design mechanical and hydraulic features of the device. The main working parts of the device are waterwheels, shaft and belt, along that the working principle of the device involves rotary motion of shaft and waterwheels, and alternative rotating and reciprocating motion of the belt. The major areas of studies to carry out this particular research work are waterpower, waterwheels, cavitation, continuity equation, law of conservation of energy, theories of shaft design, torque, moment of force, shear and bending moment, angular and linear velocity and some Statistical and Mathematical manipulations. Prominently, technical analysis of the design parameters are carried out to fix dimensions of the device parts and to determine nominal water flow capacity required for the input power. Theoretical performance of the device is evaluated at slow motion of the parts of the device to accommodate laboratory and field test by minimizing problems associated with at high velocity. A typical performance of the device at head of 0.5m, at flow capacity of 0.0005­0.0015m 3 /s and at angular motion of 52­60 rev/min is one liter volume of water from 3­15m depth of lifting at 5­35 sec time interval, and power efficiency utilization of the device is 35%. The main advantages of the device are that it uses non useful or waste water as its power source to lift useful water, it is cost effective and it can be installed any suitable places, and the working principle of device helps to avoid occasional and technical loses of useful water. The limitations of this study are that it not covers the actual and theoretical performance of the device at fast motion of device parts, and it only focuses on important mechanical and hydraulic design features of the device. The future implication of this thesis is to develop water powered technology for our daily uses.
