Key Elements Of An Electric Pressure Washer

By Morgan Lee


The pressure washer is an instrument used to remove loose paint, dust, mud, grime and mold from surfaces and objects. Most often it is used on surfaces such as buildings, road structures and vehicles. An electric pressure washer is one of the many versions of this device. It uses an electric motor to power up.

The volume of these devices is measured in liters or gallons per minute. The total force or power of the pump is identified in either pounds per square inch, bars or pascals. This can be altered using the unloader valve.

This model of washer differs from that of a parts washer. Typically parts washers are low in their pressure and high in volume. They come in a cabinet and are used for cleaning dirty parts. The water power that these devices can generate is usually more than what a regular pressure unit could do. Also, these washers, because they contain the solution inside the unit, are more environmentally-friendly, which is not true of many other models.

Most of these devices have either an electronic motor or a gasoline engine. They also have trigger-style switches, nozzles that can be changed out and an attached hose. Some versions allow for the detergent to be mixed into the st ream of water, which is beneficial when cleaning. Every device contains a low or high-strength injector. The velocity and high force created by these products is what allows them to add to their power.

Pumps cannot take out more water than what is present in the source connected to the device. If there is not enough water in the machine, it should not be run. If it is powered on and there is nothing inside, cavitation damage may occur, which can cause major problems for the pump parts.

The water that shoots out of these machines does so with strong force and so these units are often used for the purpose of cleaning. The water power is so strong that it can take of layers of paint, debris, dirt, mold and grime. If it needs to be used on an external source, it may be a gas or propane model because it offers more versatility in movement and does not require an outlet. Indoor jobs should be handled with an electric model so that exhaust fumes do not get inside and it is not as loud.

These machines are classified based on the kind of energy or fuel that is used to power them. There are at least seven different models. Some examples: ultra high, petrol, hydraulic high, gas, steam cleaner, diesel and the electric pressure washer. Be cautious when operating these devices, they are dangerous. Read instructions and as a general rule, keep it away from kids.
