A gozo-liquid mixture under pressure washes away dirt from surfaces with a small amount of water. Consider which Best Car Pressure Washers are best suited for household use.
The principle of operation of high pressure washers, their types
The new tool has become in demand for washing facades and paths, cars, special coatings. There was a need for household light installations.
The main unit of any sink is a high-pressure pump or a pump that receives energy from an electric motor. The task is to repeatedly increase the pressure of the outgoing jet. The pressure depends on the performance of the pump and the power of the engine.
Water enters the unit through a suction hose, with a non-return valve and a filter on the intake pipe. Starting the electric motor activates the pump; the desired pressure is created on the outlet hose before the outlet. At the end of the high-pressure hose, a trigger mechanism is installed, a gun that supplies a mixture of water and air to the exhaust barrel.
The pressure of the jet depends on the power of the motor, the performance of the pump. According to these indicators, the instrument is classified into classes.
A domestic installation with a power of 1-2 kW, a pressure of up to 120 bars, a flow rate of 300-450 l / h is connected to the mains water supply under pressure. The plastic pump has a motor resource of up to 100 hours when it is turned on for 20 minutes per cycle.
The average level of use, involves the manufacture of the pump from aluminum, cermet or metal alloys. Engine power up to 1.7 kW provides a pump capacity of 450-600 l / h, pressure 150 bars. Mode: work 40, break 10-20 minutes. Connect with inlet pressure.
A high-performance pump, a 1.9 kW motor, creates a pressure of 150-200 bar, sufficient to destroy the layer of old paint, knock off ice and fresh concrete growths, and clean pipes. The devices can use heated water, have a three-phase power supply, and are used by professionals. The weight of the installation exceeds 100 kg.
You can buy a high pressure washer; having decided what tasks will be solved with its help. If you purchase the unit for your own use, it belongs to the amateur or medium category.
With small dimensions and energy consumption, the device is called a mini-sink. Similar tools are produced by well-known companies, have lower productivity. Depending on the configuration, the initial, middle and highest class of mini-washes is distinguished.
How to choose a pressure washer
What mini-wash to choose for the car according to the parameters? Water consumption should be 350-500 l / h, the total working life is 55-60 hours. Maximum pressure 100-120 bar, adjustable and reduced depending on the condition of the surface. The pump must be chosen metal, removable. It will last longer, and in the event of a malfunction, you will have to replace one part. A reusable inlet filter will cost more, but it does not need to be changed in the future. The optimal length of the hose is 6-8 meters. You should pay attention to where the shampoo is served. It is better if on a gun, then you can use any composition. The cost of a mini-wash for a car will depend on the completeness and brand of the manufacturer.
Companies offer equipment from 3,500 to 20,000 rubles. Experts do not advise purchasing the cheapest installations, even with favorites they do not always withstand the declared parameters.
When choosing which minisink to buy, you need to use the principle of reasonable sufficiency. If you rarely use the device, do not participate in the rally, the facade is not covered with mud; you can use equipment with a short service life.
