Hydraulic Ram Pump (Hydram): Build and Performance Test

Approx. component budget: Rs. 5,000 - 9,000

Objective

Measure how delivery height, drive-pipe length and waste-valve setting change the flow and efficiency of a hydraulic ram.

What you will build

A ram pump made from pipe fittings with a waste valve, delivery valve, air chamber and drive pipe, run from a small elevated tank or a stream.

Results you can expect

• Delivery flow vs delivery head
• Efficiency
• Best waste-valve stroke
• Effect of drive-pipe length

What you will learn

Water hammer, valves, pressure surge, and pumping without electricity or fuel, useful for villages and farms.

Tools and notes

Measuring bucket, stopwatch, pressure gauge, Excel. Needs a water supply with some height difference. Use fittings rated for the pressure.

Resume points from this project

• Built and tested Hydraulic Ram Pump (Hydram): Build and Performance Test; objective: measure how delivery height, drive-pipe length and waste-valve setting change the flow and efficiency of a hydraulic ram.
• Measured and analysed delivery flow vs delivery head and efficiency; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
