I. What is a High-Pressure Washer?
1. Introduction to High-Pressure Washers
A high-pressure washer is a machine that uses a power device to generate high-pressure water from a high-pressure plunger pump to clean the surface of objects. It can detach and wash away dirt, achieving the purpose of cleaning the object’s surface. Because it uses a high-pressure water jet to clean dirt, high-pressure cleaning is also recognized as one of the scientific, economical, and environmentally friendly cleaning methods.
2. Principle of High-Pressure Washers
The impact force of the water is greater than the adhesion force between the dirt and the object’s surface, so the high-pressure water will detach and wash away the dirt, achieving the purpose of cleaning the object’s surface. Because it uses a high-pressure water jet to clean dirt, unless it’s very stubborn oil stains that require a little detergent, the foam generated by the strong water pressure is usually sufficient to remove general dirt.
3. Classification of High-Pressure Washers
According to the water temperature, high-pressure washers are divided into two main categories: cold water high-pressure washers and hot water high-pressure washers.
According to the driving engine, there are three main categories: electric motor-driven high-pressure washers, gasoline engine-driven high-pressure washers, and diesel engine-driven high-pressure washers.
According to their use, there are three main categories: household, commercial, and industrial.
High-pressure washers with different driving engines can adapt to different application areas to achieve cleaning purposes. When choosing a product, you should consider factors such as the specific application, usage amount, and whether hot or cold water is needed.
II. What are the Advantages of High-Pressure Washers?
1. No environmental pollution: High-pressure washers use tap water or industrial water as the medium, which is colorless, odorless, tasteless, and non-toxic, causing no pollution to the environment. It is an environmentally friendly cleaning method.
2. Non-corrosive to metals: The high-pressure water jet does not contain any acids, alkalis, or other additives, so it does not corrode metals or damage pipes and equipment, extending the service life of the equipment.
3. Wide range of applications: Any area directly hit by the high-pressure water jet, whether it’s the inner and outer walls of pipes and containers, building surfaces, or hard scale and dense blockages, can be quickly broken down, detached from the base material, and cleaned. There are no special requirements for the size, shape, material, or type of dirt on the equipment and facilities, making it very widely applicable.
4. Low cleaning cost: Cleaning only requires water, resulting in low cost and high efficiency.
5. Water and energy saving: Water jet cleaning uses high-pressure fine jets, with nozzle diameters of only 0.5-2.5mm. The used water can also be recycled, making high-pressure cleaning machines water and energy-saving equipment.
III. Applications of High-Pressure Cleaning Machines
1. Cleaning and maintenance of various motor vehicles, construction vehicles, engineering machinery, and agricultural machinery and their components, such as using a car wash gun to clean cars, bulldozers, concrete mixers, tractors, etc. It is the ideal cleaning tool for individuals and small vehicle maintenance units to clean cars and motorcycles. Ultra-high-pressure cleaning machines exceeding 500 bar can be used for concrete surface preparation, and even higher pressure cleaning machines can cut and remove various grades of concrete.
- Cleaning of building exterior walls, floors, bathtubs, and swimming pools. It is particularly effective for cleaning doors, windows, floors, toilets, oil stains, and corners that are difficult to clean manually.
Disinfection and cleaning of food processing plants, food processing machinery, and kitchens in hotels and restaurants.
High-pressure water guns are widely used in industrial dust removal, urban street cleaning, urban crust removal, car washing, train cleaning, air conditioning cleaning, food processing, livestock farming hygiene, and other fields.
