The Inner Workings of High Pressure Cleaner

karcher high pressure cleaners / washersHigh pressure cleaning equipment has become an important piece of equipment in almost all types of industries. Cleaning and maintenance tasks carried out on a daily basis can be efficiently cleaned when you know how to use a high pressure cleaner. The most commonly used pressure cleaners vary from pressures of 100 to 800 bars. Cleaners that are 350 bars are great for spot surface working areas where as those with higher bars are ideal for larger surfaces.

The reason high pressure cleaner gets the job done efficiently is that the water and chemical mix break down grease and grime and the water pressure makes it easier to flush away. High pressured jets of water are able to blast away dirt without causing any damage to hard surfaces as it hits the surface with a high kinetic energy. These units are water pumps that are powered by an electric motor.

How does a high pressure cleaner work?

The washer takes in ordinary tap water and the pump then accelerates the water to a high pressure, which in turn is squirted from a hose via a trigger gun. Depending on what you are cleaning, there are several different types of attachments that can be fitted to the end of the hose. Domestic washers are usually powered by electricity, whereas the larger versions are powered by petrol.

The largest and most powerful has a pressure of around 3400psi and is used mainly in the marine and shipping industry. The basic principles of how a pressure cleaner works is simple as the detergent in the container flows though one hose, and the water, hot or cold flows through a separate hose and when entering the unit is filtered.

The Main Components Found Inside a High Pressure Cleaner

The washer is either powered by a diesel engine or electric motor. The water and detergent is mixed together when the unit is switched on and the pump then squirts out the soapy water via a high pressure reinforced exit hose or whatever other attachment one is using. The unit comprises of a water inlet hose that connects the washer to a tap or other water supply.

There is a filter in the inlet hose that prevents dirt from entering the washer, as the last thing you want is debris or grit clogging up the washer or coming out at a high speed on the other end and damaging the surface you are cleaning. Small washers run off domestic electricity supply and the larger models run off compact petrol engines which power the water pump.

Understanding How It Works

The main component of the pressure washer is the water pump and it is driven at high speed by the petrol or electric motor. The pump sucks water from the tap and while pushing the pump in the opposite direction squirts water out into a high-pressure jet. The water pump can handle a water flow of around four to eight litres per minute.

The hose is a tube that runs out of the washer to the cleaning attachment you are using. These tubes are reinforced with two layers of high density plastic and are reinforced with wire mesh. The hoses on a pressure washer’s safety margin are around three hundred percent. For example if the pressure washer is rated at 2000 psi, the hose should be able to cope with pressures of around 6000psi comfortably.

High-pressure Cleaners are Versatile

Depending on what you are cleaning, you can switch cleaning attachments from a single trigger gun to a rotating brush or spinning wand spray. These attachments are steered by the high-pressure water force flowing through them. Most high power cleaners come with RCDs that are built into the power supply in case of an electrical fault. A high power cleaner will get the job done efficiently with minimal water wastage.
