A pump is a device which moves slurries and fluids
with the help of mechanical action. Pumps
can be classified into three major groups according to the method they use to
move fluid: displacement, direct lift or gravity pumps.
Design-
The design of a conventional water pump is to take
the existing water and increase the rate of flow of water. By speeding up the
water in the pump, the pump is creating a lower pressure at the inlet and thus
creating a vacuum. The water comes in from the low-pressure
side, the outlet of the pump gets a higher pressure and pushes the water out.
An impeller inside the pump housing is like a
propeller blade, but not so dramatically curved. Hence creating a low pressure
on one side and a higher pressure on the other. Every pump is supposed to have
a screw to create a suction force. The pressure differential pulls water, or
liquid toward the low pressure and out the high-pressure
side, much like an airplane pushes air
rearward to propel forward. It is then sealed with a double or triple neoprene
rubber to avoid wear and tear.
New cars use an electric temperature controlled
fan that will continue to cool the engine even after shut down.
Process-
·
Downstroke:
When we lift the handle of the water pump
is upwards, the piston gets pushed down. This is known as downstroke. In this
condition, the volume of the lower part decreases while the pressure increases.
As a result, water from the lower level increases.
·
Upstroke: The
handle of the water pump is pushed down
and the piston shifts upward. Water pressure increases and water level
decreases. And water comes out if the spout.
