How pressure washer works

Pressure washers are powerful cleaning tools that use high-pressure water to remove dirt, grime, and stains from surfaces. Here’s a step-by-step breakdown of how they work:

Components of a Pressure Washer

1. Water Inlet: Connects to your water supply, typically via a garden hose.
2. Electric Motor or Gas Engine: Powers the pump.
3. Pump: The heart of the pressure washer, it pressurizes the water.
4. High-Pressure Hose: Carries the pressurized water from the pump to the spray gun.
5. Spray Gun and Nozzle: Controls the release of the pressurized water.

How It Works

1. Water Supply Connection: Attach a garden hose to the water inlet of the pressure washer. Ensure the water supply is turned on.
2. Powering the Unit: Turn on the electric motor or start the gas engine, which powers the pump.
3. Water Pressurization: The pump draws in water from the inlet and rapidly increases its pressure, usually between 1,000 to 4,000 PSI (pounds per square inch).
4. High-Pressure Hose: The pressurized water travels through the high-pressure hose to the spray gun.
5. Spray Gun and Nozzle: When you pull the trigger on the spray gun, the pressurized water is released through the nozzle. Different nozzles can be attached to achieve various spray patterns and intensities.

Types of Nozzles

• 0-degree nozzle: Produces a pinpoint jet of water for tough stains.
• 15-degree nozzle: Offers a narrow, powerful spray for heavy-duty cleaning.
• 25-degree nozzle: Provides a medium spray for general cleaning tasks.
• 40-degree nozzle: Delivers a wide spray for delicate surfaces and rinsing.

Cleaning Action

The high-pressure water effectively blasts away dirt, grime, mold, and other contaminants from surfaces. The combination of water pressure and the correct nozzle allows for efficient and effective cleaning, whether you're washing a car, cleaning a driveway, or removing mold from siding.

Additional Features

• Detergent Injection: Some pressure washers have a detergent injection system that allows you to mix cleaning agents with the pressurized water for enhanced cleaning power.
• Thermal Relief Valve: Prevents the pump from overheating by releasing hot water and allowing cool water to enter.
