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. The main
advantages of the device are that it uses non useful or waste water as its power source to
lift useful water 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.
