High pressure car washer has become a familiar household appliance for many families

Basic structure of high pressure car wash machine

The basic structure of a high-pressure car washer is usually made up of 3 main parts:

• Engine
• Pump head
• Included accessories : pressure hose, spray gun, nozzle, water source connection, chemical container, …

Engine construction (motor)

Motor, also known as motor, is the part that provides power to all parts of the machine, converting electrical energy into mechanical energy . This part has 2 popular types on the market: electric motor and gasoline engine .

Pump head construction

The pump head is the part that has the role of absorbing water, increasing the pressure so that the water flow is strongest according to the design of the machine. The pump head is attached to the engine and water source, and there is also an attached filter device to remove dirt to avoid clogging the nozzle or entering the machine.

The pump head structure of the high pressure car washer includes the outlet water, the inlet water, the oil filling position, and accessories such as pressure gauges, pressure regulating valves, and pulleys.

• Pressure hose:

The main function of the spray line is to conduct water. However, due to the strong frictional force from the water flow, the spray lines are usually made of high-quality plastic outside and steel core mesh inside. Depending on the intended use, the wire length will be different.

• Spray gun:

The spray gun is the part the user holds to move the water flow to the required position. This accessory is also available in different sizes depending on the intended use. Some types will attach a soap dispenser to make cleaning more effective

• Nozzles:

Nozzle is the part located at the top of the spray gun. The main task of the nozzle is to regulate the amount of water coming out and the spread of the water jet. The larger the hole size is, the larger the water jet will be and vice versa.

• Pressure Gauges:

A pressure gauge is a type of device used to measure the pressure in water, so that the user can adjust the pressure during the use of the machine.

• Machine case:

Pressure washer shells are usually made from high-quality stainless steel and PVC, highly anti-rust due to contact with water, high durability, and can withstand great pressure.

Working principle of high pressure car washer

The principle of operation of a high pressure car wash is to take advantage of the pumping and pushing of water in the machine system.

• The process begins when the high-pressure engine draws water from the supply at low pressure
• Next, the machine will pump water through the one-way valve system into the pressure chamber.
• Here, the engine will convert electrical energy into mechanical energy for the piston to work. Piston moving up and down will increase water pressure.
• The pressure valve in combination with the small duct in the spray gun will create a powerful jet of water.

Notes when using a high pressure car wash

• Periodically clean the water filter head, thoroughly clean it to remove all kinds of dust, garbage, and residue entering the product to avoid damaging the device.
• Check and ensure the safety of the power source before use, to avoid leakage, fire, unsafety when using.
• Before use, it is necessary to priming the machine for easier operation.
• Do not use a high-pressure sprayer to spray on people or pets, which can easily cause unnecessary injury.
• When not in use, turn off the machine and turn off the water to prevent unintended risks.

When using a car wash at home, you should pay special attention to keep it out of the reach of children, strictly follow electrical and water safety measures to avoid unnecessary accidents.
