Working principle of high pressure water pump

The high-pressure water pump is divided into three-phase electric and two-phase electric power, and is completed by the reciprocating movement 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, and the inner cavity of the plunger sleeve communicates with the water passage in the pump body, and the water is quickly filled into the water chamber. When the cam is on the roller of the roller, the plunger rises. Move up from the plunger until the water hole is blocked by the upper end of the plunger. During this time, as the plunger moves, water is drained from the water chamber and flows into the passage. So this lift is called the front stroke. When the plunger stops the water hole, it begins to water pressure. When the piston rises, the water pressure in the water chamber rises sharply. When the pressure exceeds the elasticity of the outlet valve and the upper water pressure, the water valve is pushed to the top and the water pressure inlet pipe is sent to the water sprayer. The time when the water inlet on the plunger sleeve is completely blocked by the end face of the plunger is called the starting point of the theoretical water supply.

The plunger continues to move upwards, the supply of water continues, the water is pressurized until the spiral cone plunger moves the plunger sleeve until the return hole, and when opened, the high pressure water passes from the water tank through the longitudinal groove of the plunger and the pump body plunger The hole returns to the channel. At this point, the water pressure in the piston sleeve water chamber drops rapidly, and the water pressure drops back to the valve seat, and the water stops immediately. At this point, although the plunger continues to rise, the water supply has been terminated. The opening time of the return hole on the piston sleeve is called the theoretical end point of the feed water. During the entire upward movement of the plunger, only the stroke of the intermediate portion is the hydraulic pressure process, which is also the effective stroke of the plunger.
