For a long time, we have been using pressure washers for
almost all cleaning needs. However, the vast number of people are not aware of
the mechanisms and working of a pressure washer. Well, you do not need to
understand in details the whole mechanisms of a pressure washer, but you should
have some basic knowledge of what’s happening during the cleaning process.
Having a basic knowledge of the workings of a pressure
washer means you will be able to explain and troubleshoot issues such as a drop
in pressure, spark plug issues or a sudden loss in water flow. From the basic
physics, a pressure washer works on the foundations of Pascal’s Law, which
states that when pressure is applied at one point in a fluid that is stored in
an enclosed container, the pressure gets distributed equally in all directions
in contact with the fluid. This law forms the basics of fluid dynamics. When
fluid is compacted in an enclosed area, and pressure is applied at that point,
pressure travels through the fluid and is felt equally by every molecule of the
fluid.
The Working of Pressure Washer
At the heart of every pressure washer we have an electric
motor which is responsible for driving the pump system. For the pumps to work
correctly, they need water, which normally comes from the garden hose. This
water flows into a twin-walled container or casing around the motor to cool
down before it is put under pressure. This helps in reducing noise as well as
extending the run time of the device.
The motor then drives a wobble plate moving the three
pistons up and down. The downward motion of the piston draws water through the
suction valve into the piston chamber or cylinder. When the piston moves up
again, water is pushed out of the piston chamber through a pressure valve to
the side of the injector. If required, cleaning agents are then added to the
injector, with water flowing out of the pump to the high pressure gun.
All these processes happens so fast and in real time such
that once you have turned the device on, you can immediately press the trigger
and start cleaning. Cleaning with a pressure washer saves a lot of time as well
as water. While about 3500 liters of water flow through a garden hose in an
hour, a pressure washer only uses about 500 liters, with the saving effect
explained by the high water pressure speed.
