The Portable Pressure Washer For Sale's pressure washer or power washer is a high pressure mechanical sprayer used to remove loose paint, mold, dirt, dust, mud and grime from surfaces and objects such as buildings, vehicles and concrete surfaces. The volume of a pressure washer, expressed in gallons or liters per minute, is usually designed into the pump and is not variable.

It is important that the water supply is sufficient for the pressure washer connected to it, as lack of water can lead to cavitation and damage to pump elements. Make sure your water source can deliver the gallons per minute required by the pump.

A basic pressure washer consists of a motor (electric, internal combustion, pneumatic or hydraulic) that drives a high-pressure water pump, a high-pressure hose, and a trigger gun switch. Just like garden hose nozzles are used to increase water velocity, pressure washer nozzles create high pressure and flow velocity.

Different types of nozzles are available for different applications. Some nozzles produce jets of water in a triangular plane (fan-shaped pattern), while others emit fine, fast-circling jets of water (cone-shaped pattern). Nozzles that provide higher flow will reduce output pressure. Most nozzles attach directly to the trigger gun.

Some washing machines with proper nozzles allow detergent to be introduced into the water stream, aiding the cleaning process. There are two types of chemical injectors to choose from - a high pressure injector (downstream injector) that introduces the chemical after the water leaves the pump and a low pressure injector (upstream injector) that introduces the chemical before the water enters the pump. injector). The type of injector used is related to the type of cleaner used, as there are many chemicals that can damage the pump if an upstream injector is used.

Washers are dangerous tools and should be handled with due regard to safety instructions. The water pressure near the nozzle is strong enough to peel the flesh from the bones. Particles in the water are ejected from the nozzle at high speed. The cleaning process can push objects off the surface being cleaned, and it's fast. Because high-pressure water enters cracks and voids in the surface, pressure washers can easily damage tarmac if aimed directly at the tarmac.

Most consumer washing machines are either electric or gasoline powered. Electric washing machines plug into a common outlet and supply tap water, usually up to about 2,000 psi (140 bar). Pneumatic gaskets can provide twice the pressure, but they are not suitable for enclosed or indoor areas due to the danger of engine exhaust. Some models can produce hot water, which is great for loosening and removing oil and grease.
