PROBLEM STATEMENT
In this project, we are required to design a hydraulic ram pump to fill a water tank at a height of 20m from river flow. The conditions are as follows:
River Water (source): Depth = 0.5m Wide = 1.5m Flowrate = 120m /sec
Tank (to be filled): Volume = 1200m3.
River Water (source): Depth = 0.5m Wide = 1.5m Flowrate = 120m /sec
Tank (to be filled): Volume = 1200m3.
Theory on Hydraulic Ramp (Hydram)
Pump
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.

- No Velocity
- Very High Pressure
- Water Hammer Effect
The water hammer effect is a phenomenon that increases the pressure of a water pipe in a short period of time.
DESIGN METHODOLOGY FOR HYDRAM PUMP
Considerations in hydraulic ram pump system design
The following factors need to be considered in hydraulic Ram pump system
design.
- Area suitability (head and flow rate)
- Flow rate and head requirement
- Intake design
- Drive system
- Pump house location
- Delivery pipes routing
- Distribution system
Basic Parts
From the figure it shows a typical hydraulic ram installation that comprises
- Supply
- Supply pipe (drive pipe)
- Impulse valve/ waste valve/snifter valve
- Delivery valve
- Air chamber
- Delivery pipe
DESIGN
When we design a water system using ram pumps, we like to know before we build it, how much water it will deliver to how much head and with what efficiency manually manipulating these parameters using design methodology for different input parameters.Afterthat, we then design the hydram using SOLIDWORKS software which a CAD (computer aideddesign) software as .

Applications and limitations of hydraulic ram pumps
For any particular site, there are usually a number of potential water lifting options. Choosing between them involves consideration of many different factors. Ram pumps in certain conditions have many advantages over other forms of water-lifting, but in others, it can be completely inappropriate.
The main advantages of ram pumps are:
- 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.
The main limitations are:
- 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.
