If you run a mobile pressure washer business it is extremely important that you know the components so you can troubleshoot in the field while you are online with the manufacturer’s help desk or equipment vendor. Most problems that are encountered on the job can be easily fixed so you do not lose any money in the field.
Your engine has a single crankshaft where all the power goes. In a car, this crankshaft goes to a transmission. On your machine there is a circular pulley pressed or wedged on to the crankshaft. The pulley has two grooves on it. A car has a pulley on the front of the engine block between the engine and the radiator also with grooves. One goes to an alternator and another goes to a water pump.
The alternator makes electricity and keeps your car’s battery charged; same on the pressure washer unit. The water pump pumps water into your engine block from the radiator to keep your car from over heating. It does this by use of belts connected to these pulleys. It’s relatively simple. If you look under the hood of you car, you’ll see. On your machine, your engine also has belts connected to the pulley. One goes to the generator. The generator makes electricity and powers:
The burner blower for heating water
The spark to ignite the fuel to heat the water
The vacuum on your truck
The lights on your machine for night work
The 110 volt outlet on your machine for your work lights and reclaim equipment
The pump on the other hand pushes the water from the pump through the hose and then through a pin size hole at the end on the gun, which gives you incredible force from your sprayer.
It is important that you understand that in all its complexity the system is relatively simple and you need to understand each component and how it works. Read this again while looking at our equipment, think about it.
