Electric pressure washer spray gun has powerful cleaning capabilities and wide applicability, it brings efficiency and convenience to many industries. But little is known about the mechanism behind the electric pressure washer spray gun.
The throttling process of high-pressure water
The core of the electric pressure washer spray gun is its nozzle design. When high pressure water is pumped from an electric pressure washer through a series of pipes to reach the spray gun, it first needs to pass through an extremely narrow nozzle. This process is called throttling. The diameter of the nozzle is usually very small, can be a few millimeters or less, which causes the water flow area to decrease dramatically, forcing the water speed to increase dramatically. According to Bernoulli's principle, when a fluid flows through a narrow area, its pressure will decrease and its speed will increase, which is the process of converting pressure energy into velocity energy when high pressure water passes through the nozzle of an electric pressure washer spray gun.
Pressure is converted to velocity energy
This conversion process is the key to the efficient cleaning capability of the electric pressure washer spray gun. In fast-moving water, each drop of water carries a huge kinetic energy, which is enough to wash away dirt and sediment from the surface. When the high-pressure water flows at high speed to the surface to be cleaned, it will produce a strong shear force, which can destroy the adhesion between the dirt and the surface, so as to achieve efficient cleaning. Therefore, the electric high pressure cleaning machine spray gun through the fine design nozzle, the pressure can be cleverly converted into speed energy, greatly improving the cleaning efficiency.
Function of control valve
The control valve on the electric pressure washer spray gun is another important component. The control valve is mainly used to adjust the size and pressure of the water flow to adapt to different cleaning needs. By adjusting the control valve, the user can adjust the pressure and flow of the water according to the hardness and dirt level of the cleaning object. For example, for more fragile surfaces, the pressure can be reduced to prevent damage; For stubborn dirt, you can increase the pressure to obtain a stronger cleaning effect. The presence of the control valve gives the electric pressure washer spray gun greater flexibility and safety, ensuring optimal results in a variety of cleaning tasks.
