Karcher how does it work

How does Karcher pressure washer work? Category: home and garden home appliances. A pressure washer is less sophisticated than it sounds. It's really just a water pump powered by an electric motor. The washer takes in ordinary water from a faucet that's a tap to you folks in the UK , the pump accelerates the water to high pressure , and then squirts it from a hose at speed through a trigger gun.

But how does a pressure washer actually work? And how is it made? Where is the motor, where does the water go once it enters the pressure washer through the garden hose, and how is the pressure created? The heart of every pressure washer is its electric motor, which drives the pump system [1]. In order for the pumps to work correctly, they need water, which is provided, for example, by a garden hose [2].

Before it is put under pressure, the water flows into a double-walled casing around the motor, which cools it down [3]. This reduces noise and also extends the device's run time. The motor drives a wobble plate, which moves the three pistons up and down [4]. The K 7 Full Control features a total of three pistons, which each work with one suction and one pressure valve.

The downward motion of the pistons [6] draws the water through a suction valve [5] and into the cylinder or piston chamber. When the piston moves up again, it pushes the water out of the piston chamber and through a pressure valve [7] towards the injector.

Cleaning agent [10] is added to the injector [8] if required. The water then flows out of the pump [9] to the high-pressure gun. Of course, in real time, this all happens so fast that once you have turned on the device, you can immediately press the trigger to start cleaning. The pressure washer pictured here features an LED display on the trigger gun, which shows the pressure level selected, as well as an example application. This makes it easy to find the right setting for every application.

Quite apart from the outstanding cleaning performance, cleaning with a pressure washer also saves water, because while around 3, litres flow through a garden hose in an hour, a pressure washer uses just to litres. When the spray lance is inserted and you squeeze the trigger, the LED-backlit indicators on the gun light up to show the current pressure level, which runs from Soft suitable for cleaning wood, sandstone or, say, a bicycle to Hard for cleaning concrete, hard stonework, tarmac, metal surfaces and more.

You can adjust the pressure and the spray pattern by twisting the Vario Power Spray Lance until the display hits the desired level. This absolutely did not happen to me. The Vario Power Spray Lance and Power Control Gun work exactly as promised, making it easy to change the pressure and adjust the pattern without needing to fiddle with the unit or stop to plug in a different accessory.

I barely needed to reach for the secondary Dirt Blaster lance. Extra points for the pull-out handle, too. The cleaning is fantastic. I used the K4 Power Control to apply snow foam to my car, rinse it off, scour moss and dirt from a tarmac driveway and clean areas of hard concrete and decking in the garden.
