Design and Fabrication Of Hydraulic Ram Pump -Mechanical Project
hydraulic ram pump designed is believed to be the most suitable and efficient for the given conditions based on the calculations performed. For the first step of designing, all the related problems are listed and understand. Then, the specifications, criteria and evaluation of the solutions are developed.
This including choosing the most suitable operational working principals for the hydraulic ram pump (hydram), outline of the theoretical background behind the
operation and its details calculations, which are being referred to the concept and theory entitles to Fluid Mechanics. This is followed by the details drawing of
the hydraulic ram pump by using the SOLIDWORKS software. From the calculation performed, the hydraulic ram pump designed with radius of 0.1m
and length of 0.5m has high and reasonable efficiency. Its flow rate to the delivery tank is determined to be 0.00069m3/s and required about 20 days and 3
hours to fill completely the tank at a height of 20 m from river flow .
River Water (source): Depth = 0.5m Wide = 1.5m Flowrate = 120m /sec
Tank (to be filled): Volume = 1200m3.
Energy Cars, airplanes, light bulb, water pumps, computers, the human body have all something in common: they need energy to work. This energy can come
from many sources such as electricity, fuel, manpower, food. Different technologies are used to transform one source of energy to another. For
example, car engines transform the chemical energy of the fuel into mechanical energy allowing wheels to rotate. Another example related to water supply
projects is electric pumps: they use electricity to transform electrical energy into potential energy of the lifted water. The potential energy is the energy of every
object due to its altitude. The object needs another source of energy to be lifted and will lose its potential energy if it falls. Hydramsare designed to lift water
(i.e. give potential energy to the water) from a low cost source of energy. Avoiding using fuel and electricity, the water hammer effect has shown to be
efficient and is the principle of hydrams.

|Design and Fabrication Of Hydraulic Ram Pump|
- Use of a renewable energy source ensuring low running cost.
- Pumping only a small proportion of the available flow has little environmental impact.
- Simplicity and reliability give a low maintenance requirement
- Automatic, continuous operation requires no supervision or human input.
- They are limited in hilly areas with a year-round water sources
- They pump only a small fraction of the available flow and therefore require source flows larger than actual water delivered
- Can have a high capital cost in relation to other technologies.
Introduction to Seals : Oil under pressure is moving in every hydraulic circuit. Since oil is a liquid it has the tendency to 'leak' through every gas/slot it finds during movement. This leakage of...
