Hydraulic ram pumps may be termed as
a ‘wonder machine’ or a ‘tool of the wizards’ until we know the science and
logic behind it. These machines have been popular since a long time mainly due
to its simple design and no use of electricity to get it working. Here is a
brief description of how it works.
The first prerequisite of having
a hydraulic ram pump is that the water source from where the
pump will use water should be above the pump. If this condition is fulfilled, you
may proceed to installing a ram pump.
There is a valve situated in the pump
that allows flow of water and helps in creating pressure. Once the water
catches considerable speed, this valve gets closed and pressure gets built up
inside the pipe due to inertia. The pressure thus developed forces open a
second valve due to which the high-pressure water thus developed flows through
the delivery pipe.
As water gets released, the pressure
of water on the valve also decreases and therefore the first valve, which was
closed due to high pressure, re-opens. This again creates a momentum and the
whole process is repeated again.
