What is a pressure washer?


High Pressure Washer the cleaning process is essential to the effective use of a pressure washer. A pressure washer cleans by creating a high pressure stream of water that hits the surface with a large amount of kinetic energy, thus removing the dirt mechanically, while providing a constant flow of water to wash the dirt away. Often dirt is mixed with grease or oil, or other substances, which chemically bond the dirt to the surface you are trying to clean. Sometimes even the force of high pressure water needed to break these chemical bonds is insufficient to get the surface clean without requiring excessive pressure, that is either impracticable or would damage the surface. Adding a detergent, or other cleaning chemical, or using hot water, while agitating or brushing the surface, significantly enhances the cleaning power of the pressure washer.
Detergents and soaps are used for cleaning because pure water can't remove oily, organic soiling. Soap cleans by acting as an emulsifier. Basically, soap allows oil and water to mix so that oily grime can be removed during rinsing.
Detergents cannot accomplish much until some mechanical energy or agitation is added into the equation. This mechanical energy is provided by the pressure washer. As the detergent emulsifies the grime, breaking the chemical bond, the blasting effect of the pressurized water strips the dirt from the surface, while the flowing water rinses the detergent and soil away. Warm or hot water, or steam, melts fats and oils so that it is easier for the soap or detergent to dissolve the soil and pull it away into the rinse water.
 pressure washer is a mechanical device that uses a pump to generate a high-pressure stream of water to clean surfaces. The pump is typically powered by a gasoline engine, an electric motor, or a diesel engine. The pump is a positive displacement pump that forces a specific amount of water flow from the outlet.  By restricting the flow with the nozzle, much like you do by placing your thumb over the end of a garden hose, the pressure washer produces pressure. Without the nozzle the impact of the water from the end of the pressure washer hose is similar to that from a garden hose. The narrow diameter of the nozzle increases the water's velocity and, consequently, its impact and cleaning power. The smaller the nozzle orifice, the more pressure is potentially produced. However to produce greater pressure, more horsepower is required to force the water through the smaller hole. Each pressure washer calls for a specific size nozzle to match the flow of the pump and the horsepower of the motor. Putting too small a nozzle on your pressure washer strains the components and may cause excessive wear to the machine; too large a nozzle sacrifices cleaning power.
All pressure washers produce pressure and flow. Both are important to the cleaning process. Most pressure washers also provide a method for dispensing soap or detergents, either under low or high pressure. The proper use of soap is often key to the cleaning process. Hot water pressure washer are equipped a burner system to continuously heat the stream of water, further aiding the aiding the cleaning process. Most hot water pressure washer can generate wet steam of approximately 240 degrees F, by turning down the pressure to around 150 PSI. There also true steam cleaners that generate a dry steam of approximately 320 degrees F at 150 PSI. Understanding the basic concepts of pressure flow and cleaning units will help you pick the right pressure washer for the cleaning job at hand.
