Pressure washers are power tools that we regular encounter whether in our homes or even outside. We use them to quickly clean and freshen up things which have gone really dirty – like our pet’s kennel and certain appliances that we may not have brought out for cleaning for an extended period of time.
Pressure washers are also regularly employed in a number of commercial establishments like car wash shops for easier and faster cleaning of a vehicle’s exterior.
Pressure washers are very easy to operate and even a first timer can only encounter little to no difficulty when he picks up the hose for the first time. Seasoned users can even operate these power tools with their eyes closed.
It is perhaps this ease in use that we often take for granted the wonderful science and engineering that make our pressure washers work. If we look inside, we will be amazed at the simplicity of its mechanics that produce so much power.
It is a good idea to know and understand the inner workings of our pressure workers for us to better appreciate these power tools and to be able to use them to their fullest potential.
What happens inside?
Before we go to the inner workings of a pressure washer, it is important that we first have a basic understanding of the force that makes it work. This is called pressure. Pressure, simply, is the amount of force that is acting in a unit area.
Increasing the amount of force over a smaller area can drastically increase the amount of exerted pressure.
Conversely, the same amount of force over a bigger area leads to a lower amount of pressure. In our model of a pressure washer, strong amounts of force are applied to the water inside a relatively small container which produces great pressure and leads to strong jets of water when we turn on the pressure washer.
Most pressure washers follow this relatively simple model of operation:
Detergent and water are drawn into the pressure washer through separate intake hoses.
A pump powered by an electric motor mixes the detergent and the water together. (In gas models, the motor is powered by gas.)
The same pump propels the mixture of detergent and water out through exit hose.
In between these steps, the pressure washer may also heat the mixture up to a desirable temperature. The exit hoses and any accessories attached help maintain the pressure of the mixture because of its narrow size vs the stronger force coming from the pump.
Why do we have to understand how do electric pressure washers work?
Your pressure washers will work at a turn of a switch even if we do not know what happens inside. So why do you have to learn all the inner workings of a washer? Knowing how these power tools work can lead not only to a higher efficiency while in use, but also to a longer life of the washer.
Knowledge of how a pressure washer works can lead to a better understanding of the mechanics behind it. This means that you can easily grasp the changes between the ebbs and flows of the water and soap mixture jetting out from your hose which you can easily adjust now to your preference.
Do you need stronger pressure? Then turn up the motor power or replace your hose with a narrower one. Are you already getting blown out? Then replace your hose with a wider one or lower the power of the motor.
Adjustments can be made easier even while on the fly if you have a solid grasp on what happens inside.
Having know-how on what happens inside your pressure washer when you turn it on can also help extend the life of the machine and to easier troubleshooting.
Knowing what each component does makes it easier to identify possible causes of problems and to replacement of only parts and not the washer itself. A broken intake hose or a pump does not mean that you have to get a new washer entirely.
Spare parts are also available on the market and you can get your pressure washer up and running again at a cheaper cost.
