Working principle of high pressure water pump
Jul 21,2022
The high-pressure water pump is divided into three-phase electricity and two-phase electricity, which is completed by the reciprocating motion of the plunger in the plunger sleeve. When the plunger is in the lower position, the two water holes on the plunger sleeve are opened, the inner cavity of the plunger sleeve is communicated with the water channel in the pump body, and the water quickly fills the water chamber. When the cam is pressed against the roller of the roller body, the plunger is raised. Move upward from the beginning of the plunger until the water hole is blocked by the upper end face of the plunger.
During this time, due to the movement of the plunger, the water is squeezed out of the water chamber and flows into the water channel. So this lift is called pre-stroke. When the plunger blocks the water hole, the water pressing process begins.
The plunger goes up, and the water pressure in the water chamber rises sharply. When the pressure exceeds the elastic force of the water outlet valve and the upper water pressure, the water outlet valve is opened, and the water is pressed into the water pipe and sent to the sprinkler.
