High pressure cleaner pump head principle?

High-pressure cleaner in our country has a different name, most people call it high-pressure water cleaner, high-pressure water flow cleaner, high-pressure water jet equipment, high-pressure water gun and so on. \x0d\\\\\x0d\\ high pressure cleaner pump head principle: \x0d\ high pressure cleaner is to use water as the working medium, by the booster pump and power-driven unit of the two major components, usually, the power-driven pump by the completion of a suction, discharge process of the water, the ordinary water into a high pressure and low flow rate of water, and then transported to high-pressure piping, so that it reaches the high-pressure nozzle at a certain level of energy. The aperture of the high-pressure nozzle is much smaller than the diameter of the high-pressure pipe, so the water reaching the high-pressure nozzle must be accelerated in order to pass through the nozzle. In this way, the nozzle transforms the high pressure, low flow rate water into a low pressure, high flow rate jet. The amount of water flow is controlled in three ways, by increasing or decreasing the inside diameter of the pump head, by lengthening or shortening the stroke of the plunger. By increasing or slowing the reciprocating speed of the plunger. The vast majority of pressure washers use a set of valves and a pump head to form the system, with the plunger pulling water into the inlet valve and pressurizing it through the outlet valve. The valve controls the passage of water through the pump by preventing backflow. The valve consists of a spring and a bracket and operates under pressure due to the difference in pressure between the two sides of the valve. When the pressure acting on the valve is greater than the capacity of the spring, the valve opens. On the opposite stroke, water automatically squeezes the bracket against the valve seat, keeping the valve closed and preventing backflow.
