Pressure Cleaners
Introduction: A world without high pressure cleaners is inconceivable. They are widely used by many trades, in agriculture, industry and car wash. Many home and garden owners would not want to be without their high pressure cleaner either, because there is nothing as fast or thorough as a high-pressure cleaner for cleaning your vehicle, removing moss from patios, algae from swimming pools or dirt from facades. These machines are not only useful, they are environmentally friendly. There are two reasons for this claim: 1) High-pressure cleaners reduce water consumption. The restricted bore cross section (called the nozzle), which is required to increase pressure, reduces the water flow volume. Compared to a garden hose, for example, this achieves a water saving of up to 80%, assuming the average suburban household pressure of about 4.5 bar, about 3,500 litres of water flow through the hose every hour, while the flow rate through the spray lance of a high-pressure cleaner is only 400 to 600 litres in the same time. 2) Save time and cost. The actual time spent on the cleaning job is cut drastically and this, in turn, reduces water consumption even further. Pressure cleaners can help to get rid of dirt, grime, and stains off most types of surfaces including glass, wood, steel and tar using a high pressure flow of water. The spray of the water can be controlled with a trigger mechanism that allows the operator to spray water in either short bursts or a continuous spray. Water is shot at such a high pressure that it acts as an abrasive to help remove dirt and stains. This is more effective than using abrasive cleaners that can harm the surfaces you are attempting to clean. Pressure cleaners come with a variety of accessories and attachment for both commercial as well as home use. These attachments include brushes, extension wands, foam applicators, adapters and spray guns. You can either rent or buy a pressure cleaner. In the long run it will probably be cheaper just to buy one, although for the heavier duty user, why not rent first to make sure the machine does the job. Choosing the correct Pressure Cleaner Under pressure to choose the right pressure cleaner? The following guide will help you determine which pressure cleaner is right for you and alert you to issues to be aware of when buying and using pressure cleaners. Choice: PSI vs. L/min vs. CU, Electric vs. Petrol, Hot vs. Cold, Belt Drive vs. Direct, Camshaft vs. Axial Pumps. There are many options when choosing a pressure cleaner that can complicate your decision. The important thing to keep in mind is to match your needs to the equipment, which will keep your projects running smooth, and keep your overhead costs low.
PSI, L/min and CU When you are shopping for a pressure cleaner, one way to compare units is by the cleaning power of the water. • PSI - (pounds per square inch) refers to the amount of cleaning pressure the unit is capable of developing. • L/min - (litres per minute) refers to the actual flow of water through the unit or rate a which the unit sprays water. • Cleaning Units - Some manufacturers have started to use CU (cleaning units) which is simply PSI X L/min
The real challenge is to match these to your applications. Pressure cleaners rated at 1300-2200 PSI are for light, occasional chores such as cleaning a small area, lawn equipment, cars, trucks, mud or dirt. Models rated at 2200-3000 PSI are designed for more frequent users and for larger jobs such as cleaning vinyl and wood siding easier, whether the surface is being prepared for painting or to remove dirt and grime. Units rated at PSI 3000-4000 are for professional use on heavy-duty projects. Contractors and commercial users turn to this category to clean their heavy equipment, construction sites, paint preparation and other demanding projects. Some units are rated above 4000 PSI and are designed for the special, heavy duty cleaning jobs.. Electric vs. Petrol
Pressure cleaners are either electric or petrol powered. Electric pressure cleaners are low maintenance and quiet, however you need easy access to an electricity outlet. Machines which have an electric motor larger than 2.0Kw will normally need a 15amp power point rather than the standard domestic 10amp point. While smaller models are for generally for lighter duty work, they are a much cheaper entry into pressure cleaner ownership. Industrial models normally require a three phase power point. Petrol models are recommended for tasks that require more power, such as paint prep, heavy vehicle cleaning, or cleaning heavily soiled concrete. Petrol models start with PSI of 2000 and go as high as 5000. They also offer more portability, as they are not limited by location of a power point. They are however, noisier and require regular maintenance on the petrol engine, such as the air and oil filters.
Hot Water vs. Cold Water Most pressure cleaners spray cold water which is fine for most applications. However if you need to remove very heavy grease then you may need to have to opt for a Hot Water Pressure Cleaner, utilizing a diesel burner. The downside is that you should expect to pay a lot more for these. Also, the heater is an additional part that requires maintenance and care. Do not run heated water through cold water systems, since this can damage the pump O-rings and gaskets. Pumps: Belt vs. Direct, Wobble, Axial, Camshaft The water pump is really the heart of the pressure cleaner system. The main difference between belt drive and direct drive pumps is that belt drive pumps run at a lower RPM and are more insulated from engine or motor vibration, and therefore may extend the pump live. Direct drive pumps are directly mounted to the engine or motor, which eliminates the extra cost of gearbox, pulleys, belts, etc. Expect to pay a price premium for belt drives giving the same PSI, GPM, pump brand, and horsepower. However there is little actual difference in the pumps. The basic pump models are the wobble, axial, and the camshaft. The wobble pump has lower performance and efficiency (70% efficient) due to piston spring resistance on each stroke (pistons must push against the pressure in the pump PLUS the resistance from the springs).
