ADJUSTING NOZZLES TO GET THE RIGHT CLEANING POWER
Industrial pressure washers are high-powered cleaning machines that use pressurized water to eliminate stains and dirt from various surfaces. Pressure washing machines can generate pressure levels as high as 7000 psi. The pressure level of water ejected by a garden hose is only about 40 psi. Once you switch on fuel-powered or electric pressure washers, the motor or engine drives the water pump. This water pump forces water through a hose leading to the spray gun. The water finally exits through the nozzle of the spray gun.
The power of the water jet ejected by industrial and commercial pressure washers is adjustable by attaching nozzles of different sizes to enable a variety of spray patterns. It is important to understand different spray patterns and choose the right one for your specific cleaning application.
0º Nozzles: A 0º nozzle produces the thinnest stream of water. A very thin, concentrated jet of water produces more power. This is why water ejected through 0º nozzles casts maximum impact on small areas. The 0º nozzle in industrial pressure washers has been designed to tackle the toughest cleaning jobs.
15º Nozzles: A 15º nozzle creates a small spray pattern resembling a fan. Although water ejected from industrial pressure washers with a 15º nozzle will not be as powerful as the water jet from a 0º nozzle, it is still strong enough to remove paint or old finishing.
25º Nozzles: The 25º nozzle produces a wider fan-like spray pattern than is created by a 15º nozzle. The water stream generated through 25º nozzles is ideal for washing surfaces or cleaning off debris from the ground.
40º Nozzles: The 40º nozzle used by commercial pressure washers produces the widest fan-like spray pattern. Being low on power, the water jet created by 40º nozzles is perfect for cleaning or rinsing surfaces, such as windows.
Steam Nozzles: The steam nozzle is designed specifically for ejecting wet steam at extremely high temperatures. The use of high-pressured steam is the most effective way to remove grease, grime, and other hardened, stubborn deposits from machinery, concrete, and other surfaces.
There are certain points you must keep in mind about nozzles to ensure that you get the most out of your electric pressure washers. First, you must remember that whenever the metallic nozzles are subjected to high pressure levels and temperatures during the course of regular use, they can wear down and the pressure levels may drop. So, if you notice an unexplained lowering of pressure, first check the nozzles for signs of wear and tear.
Another possible reason for lower levels of pressure can be that the water supply in your area is not clean or the water consists of dirt particles. These dirt particles can clog the nozzles of pressure washers and can adversely affect the cleaning process. In such cases, it would be a good idea to use a nozzle filter.
If your nozzles need to be replaced, it is advisable to purchase replacements from the trusted supplier of your machine. Only then can you be assured of a proper fit.
