Hydraulic Ram Test Setup
Product Code : EL-HML-11057
Quick Answer: Hydraulic Ram Test Setup shows how a hydraulic ram lifts a small quantity of water to a high head using a larger quantity available at low head, on the water hammer principle. The 50 x 15 mm ram works from a 2.5 m supply head and lifts water to a maximum of 10 m.

About This Product
When flowing water in a long pipe is suddenly stopped, a pressure wave travels along it, and this water hammer effect is what drives the ram on this setup. A supply reservoir on a stand, connected to the overhead tank, feeds the pipe section, while useful and waste water are collected in separate measuring tanks and timed with a stop watch. In the HYDRAULIC MACHINE LAB, students use these readings to find the discharge of useful and waste water and the efficiency of the ram.
Frequently Asked Questions
Q1. How does the hydraulic ram work?
It works on the water hammer principle: when flowing water is suddenly stopped in a long pipe, a pressure wave travels along the pipe. This lets a large quantity of water at low head pump a small quantity to a high head.
Q2. Can the operating characteristic of the ram be changed?
Yes. Different pressures can be applied to the pulse valve to change its closing pressure and hence the operating characteristic.
Q3. What does the air vessel do?
Mounted above the valve chamber, the air vessel smooths cyclic fluctuations in the output of the ram.
