What is the first thought that comes to your mind after hearing the term “pressure washer”? We suppose you breathe a sigh of relief because it is the magic wand that eases your hectic work of cleaning.
A pressure washer makes cleaning easier for you. It removes all the dirt and blistered paints that can be hard to clean otherwise. A pressure washer is one of the helping hands you need in your life. But do you want to know how it works?
While there’s no need to know how a pressure washer works, what will you do if you face any problem using it? Thus, it’s better to understand its mechanism to avoid any future mishaps. This is what we will explain in this post.
The Main Principle of a Pressure Washer
The main concept on which a pressure washer works is Pascal’s law. According to this law, when a fluid is sealed in a container and pressure is applied to it, the pressure is distributed throughout the container in an equal manner. Thus, the principle of a pressure washer is to force water at a high speed through a fine nozzle.
You need to understand what happens inside the closed container when pressure is applied on the fluid. When fluid compresses, the pressure is placed on each molecule of the fluid and pressure flows throughout the liquid. The pressure in the container will be released through the nozzle at a high rate.
Main Components of a Pressure Washer
These are the main components that make up a pressure washer:
- Power source
- Water inlet
- Cleaning attachment
We will look at a few of these components briefly, which will help you understand the mechanism of a pressure washer:
A power source can be an electric motor or a gas engine. You can use any power source you want because the mechanism will remain the same. The benefit of each type of engine depends on where the machine is being used (i.e. indoors or outdoors).
The pump might be an axial pump or a triplex pump. Both have a cylinder and piston that will run it. The pull cord helps drive the pump that uses the engine’s momentum.
This is a tube that is resistant to high pressures and is attached to the part that cleans the area. It is an essential part of the machine as an ordinary pipe will not be able to withstand the pressure.
For these components to operate properly, a toggle switch is used. It helps control the flow of water.
How Does the Water Flow?
There are crankshafts that are attached to plungers found in the pump. The plungers help extract and eject water. They store up the water until it is used and leaves space for more water to enter.
After the plunger is moved up, water flows into the cylinder inside the plunger through a valve. In the same way, water comes out through another valve into an unloader. This unloader is connected to a switch.
When the switch is pressed, the pressurized water is released through a long nozzle.
Spring Valve Mechanism
The water is ejected as soon as the trigger is compressed. When the trigger is released, the water stops flowing. A spring valve can detect when the trigger is released that stops the flow of water. It lets the water return to the reservoir. Thus, the spring valve mechanism helps the motor run even after the water flow has stopped.
Make sure to give a supply of cold water instead of hot water because hot water will damage your machine.
Important Uses of a Power Washer
Now that you know the basic mechanism, you should also know some uses of a power washer:
- It helps you clean your vehicles like cars, bikes, boats and caravans.
- It helps you clean roadsides, pathways, driveways and house facades.
- It helps you clean all the dirt from outdoor furniture and barbecues.
- It is a great tool for stripping out rust, paint and stains from various objects present in your house.
- You can remove the caked-on mud from farm equipment that is otherwise an impossible task.
- It cleans out the birdbath as well that has stubborn stains on it. The only thing you need to make sure is that you don’t strip off any paint with the high pressure.
You now know how your pressure washer works, so if it stops working, you know the right place to look for faults.
