Many homeowners all around the world love the idea of do-it-yourself cleaning tasks. It makes them become more knowledgeable about the simple yet rather sometimes complicated task of cleaning.
There are some do-it-yourself homeowners who like to clean the old-fashioned way with the use of mops, brooms, brushes, cloth rags, cleaning agents, sprays, etc. These items certainly do their job, but it requires a lot of backbreaking effort.
In the old days, only the industrial and commercial sectors can afford to acquire these pressure washer units. It not only gets the cleaning job well done, but it also requires only a small amount of time. This is what many of us would like to have, a cleaning machine that helps us clean efficiently with only a little effort exerted and it uses up only a small portion of our time. However, because it was once a luxury many of us could not afford at that time, we opted to find other ways to clean our homes efficiently such as using improved cleaning agents, static-powered dusters, fancy mops and tinier vacuum cleaners. These cleaning items are great to use at home, but they do not last very long, unlike a good quality pressure washer. Fortunately, as time passes by and technology gets more advanced, the affordability and availability of pressure washers for home use has certainly delighted many homeowners.
What exactly is a pressure washer? According to Wikipedia, a pressure washer is a mechanical sprayer that, depending on nozzle size, can be used as a low volume high-pressure water cleaner or a high volume low pressure water cleaner to remove loose paint, mold, grime, dust, mud, and dirt from surfaces and objects such as buildings, vehicles, and concrete road surfaces.
To understand how it works, below are the basic components of a pressure washer:
1. Pressure Washer Motor – There are many varieties of motors used in different kinds of pressure washers. It may also depend on the location and variety of the applications. Most high-powered pressure washers that are used in commercial settings typically have diesel or gasoline-powered engines. Due to the fact that many of the commercial cleaning jobs involve lots of time are performed in the open air, these types of motors were specially created to operate for a longer period of time without overheating unlike the electric-powered version. In addition, they are very useful when used offsite, where there is no electricity source available. Oftentimes, pressure washers that have electric-powered motors are utilized for light to moderate washing jobs such as cleaning jobs in automobiles, smaller motorboats and households, and they are extremely effective when utilized for indoor tasks because their engines do not tend to produce unhealthy smoke or fumes.
2. High Pressure Water Pump – The high pressure water pump is considered to be the pressure washer’s core or “heart”. There are actually two types of pumps that are available, depending on the pressure washer unit – piston pumps and plunger pumps. Both the piston pumps and plunger pumps are reciprocating pumps that utilize a piston or plunger in order to move media through a cylindrical chamber. The piston or plunger is activated by a steam powered, hydraulic, pneumatic, or electric drive. Piston pumps and plunger pumps can also be referred to as high pressure pumps, high viscosity pumps or service pumps. Between the two pumps, the plunger pumps are considered to be the most efficient and they also have a much longer lifespan. Because of those characteristics, they are the most commonly utilized pumps nowadays and they are found in superior modern pressure washers. There are units that have duplex and even triplex plunger pumps. Plunger pumps are typically made of ceramic, which is a very tough substance that has great anti-resistant properties. They are very sturdy and when they are properly maintained, they will never cause you any hassle. Due to the fact that it can produce a more stable flow, the triplex pump is the most sought-after type of pump in the pressure washer market today.
3. High Pressure Hose – A high pressure hose is made up of an inner tube in which the water can pass through. This is covered with wire mesh that is either single or double braided. This in turn is surrounded by an external rubber cover. Typically, the cheaper hoses are covered with a thermoplastic substance, whereas the better hoses are covered with a rubber substance. Most of the hoses are created with burst ratings that are four times their graded working pressure. Whenever you are matching hoses for pressure washers, use a hose that is rated somewhat greater than the PSI (pounds per square inch) rating of your machine. This will make your hose last longer. Normal PSI ratings include 3000 PSI, 4000 PSI, 4500 PSI, 5000PSI and 6000 PSI. Both the 3000 and 4000 PSI hoses are typically single braid while hoses having a burst rating of 5000 PSI or more have almost always a dual-braided (or 2-wire) mesh.
4. High Pressure Nozzles – Most people think that the nozzles are simple and seemingly insignificant accessories of a pressure washer. These accessories are actually the ones that make the whole high pressure system work perfectly. Pressure washer nozzles possess a small pinhole that is sized accordingly in order to make the required pressure at a particular flow. The hole serves as a restriction in the water flow. Once the flow from the pump is forced all the way through this restriction, pressure is then created. That moment is the time that you have a complete pressure washing system in working condition. The pressure washer nozzles that have holes which are most nearly sized to the specific features of the pump will usually provide you the greatest pressure washing performance. The high pressure nozzles are very important accessories in a high-powered pressure washer as they produce the right amount of restriction wherein water flow becomes “pressurized” and directed with such powerful pressure. In reality, a worn-out nozzle will have a significant decrease in pressure. A mismatched hole may have the same decreased pressure outcome as well. The best thing that you can get out of your pressure washer is a nozzle that has virtually no deterioration at all and one that has a spray hole which is appropriately sized for your pumps’ output.
