Energy-saving type high-flow high-pressure water pump and method for high-pressure washer

Abstract

The invention relates to the technical field of high-pressure water pumps, in particular to an energy-saving type high-flow high-pressure water pump and method. The energy-saving type high-flow high-pressure water pump is characterized in that when high-pressure liquid flows from a water inlet on a valve mouth through a high-pressure water inlet pipeline and passes a primary throttling hole in the water inlet and then sequentially enters a vacuum cavity A and a vacuum cavity B, accelerated water flow and vacuum can be generated in the vacuum cavity A and the vacuum cavity B due to the facts that the inner diameter of the vacuum cavity A is smaller than that of the vacuum cavity B and the high-pressure fluid is subjected to two-stage throttling, wherein the vacuum cavity A and the vacuum cavity B are arranged end to end in a linear mode. Consequently, tap water and cleaning solution can be sucked into the vacuum cavity B through a high-flow suction hole and a cleaning solution suction hole respectively in a negative pressure order and flow out of a secondary throttling hole at a high speed along with high-pressure water flow, and then the tap water and the cleaning solution are jetted out of nozzles through the high-pressure water pipeline and a water gun. The energy-saving type high-flow high-pressure water pump is convenient and reliable to operate; high-flow output can be achieved while high system pressure of the water pump can be maintained; the generated flow and jetting range exceed those of a traditional water pump more than twice under the condition of using the same motor and consuming the same power.

Description

[technical field] [0001] The invention relates to the technical field of high-pressure water pumps, in particular to an energy-saving high-flow high-pressure water pump and method for high-pressure cleaning machines. [Background technique] [0002] In the high-pressure cleaner industry, regardless of whether it is an electric cleaner or a gasoline cleaner, its pressure and flow are restricted by the power of the motor or engine, and the actual cleaning capacity and cleaning range cannot be brought into full play. For example, the motor washing machine, because of the limitation of voltage and current, the working pressure and flow generated by the pump body often cannot meet the actual needs, either the flow is insufficient, or the range is not enough. Although the pressure and flow generated by the gasoline cleaning machine are much higher than those of the electric cleaning machine, the gasoline cleaning machine is usually used in some professional places, which requires a...

Problems solved by technology

[0012] However, the cavitation jet gun increases the spray distance and enhances the gasification effect of the cleaning liquid, but it cannot increase the flow rate of the high-pressure water pump itself, and cannot improve the cleaning effect well.
