There are many tools used in many cleaning purposes such as in car washes. One of those is pressure washer. Pressure washers are normally used to make it easier to clean off dirt, grime, mold, dusts, mud, oils, and other mildews from different surfaces such as building surfaces, vehicles like cars, and concrete road surfaces, particularly in asphalt. So what is a pressure washer?

Anatomy of a Pressure Washer

A pressure washer is a mechanical sprayer that uses high-pressure water to clean and remove dirt and mildew from different surfaces, such as those mentioned above. It is composed of a motor that directly drives a water pump, a pressure washer hose, and a trigger gun-style switch.

These types of equipments can either be bought or rented. Its equipment, especially its pressure washer hose, can also be bought separately. Its motor, however, are known to produce different pressures from 50 bars (750psi) up to 1200 bars (30,000psi) or more.

Other than the motor, the pressure washer hose, and its trigger, its nozzle also plays a major role in its usage. Just as a garden hose nozzle is used to increase the out-flowing dynamic pressure of the liquid, a pressure washer adds its own power to force high-dynamic pressure.

There are currently different types of nozzles used in different applications. Some of the most common nozzles can eject a triangular plane, while others can emit a pencil-thin jet of water, which spirals around rapidly.

To make cleaning easier and faster, cleaning agents such as detergents can also be used in conjunction with the water stream, assisting in the cleaning process. These types of pressure washers are found in many car washes.

Precautions

Though useful, there are several precautions that users should always follow when using a pressure washer, particularly for those with 1200 bars (30,000psi) and more.

According to experts, the water that supply’s the pressure washer, such as tap, should equally flow or superior to that of the washer, so that the pump is never starved, which can damage the motor.

Another is that the water from the nozzle is said to be powerful enough to strip flesh from bones. Objects in the water supply can be ejected from the nozzle at great velocities. The cleaning process can propel objects from the surface being cleaned, also at great velocities.

Pressure washers also have a tendency to break up asphalt if aimed directly at it, due to high pressure water entering cracks and voids in the surface. As for removing graffiti, pressure washers can usually overclean the surface leaving a permanent scar on the building surface or any surfaces.
