How Ram Pump Works?

Operating Principle
The operational principle of hydraulic ram is very simple. It uses the water hammer.effect in the ramto transmit water from lower elevation to a much higher elevation..Ram pump has only two moving parts that dictates the whole operation. These are the waste valve or the impulse valve  and the check valve. Of course there are are other parts that supports channeling of water.

In order to operate, you must have a source of water situated above the pump. For example, you must have a spring source at least 1 meter above the Ram so that the water from the spring could flow and build up momentum towards the ram. The spring box and the ram is connected by a pipe called drive pipe..
    * Once the water reaches its maximum speed, this waste valve (impulse valve) slams shut, thus creating a water hammer effect.
    * As it slams shut, the flowing water develops a great deal of pressure in the pump because of its inertia.
    * The pressure forces open a second valve, the check valve.
    * High-pressure water flows through the second valve (check valve) to the delivery pipe (which usually has an air tank to allow the delivery pipe to capture as much high-pressure water as possible during the impulse).
    * The pressure in the pump falls. The first valve re-opens to allow water to flow and build up momentum again. The second valve closes.
    * The cycle repeats

The volumetric efficiency of the ram depends on the FLOW of water from the source; the FALL or the height of the water source from the ram and the LIFT or the difference in height between the ram and the reservoir.

Disadvantages
The disadvantage of ram is that, through the waste valve,  it throws back to ground  considerable amount of water since not all water that enters the ram are pumped uphill as compared to electrically or petrol driven pumps where it has no waste water...
