Abstract

The invention discloses a high-pressure pump capable of maintaining stable output of high-pressure liquid, comprising: a high-pressure pump body, in which a reciprocating pressure piston is arranged, and the high-pressure pump body provides high-pressure liquid through the pressure piston; The pressure tank and the high-pressure pump body are connected through a one-way valve, and the pressure-stabilizing tank is used to output high-pressure liquid with stable pressure; and a driving mechanism, which includes: a motor; The middle part of the pressure rod is hinged with the pressure piston; and the runner with a handle is driven by a motor, and the handle is slidingly matched with the chute. When the runner rotates, the handle drives the pressure rod to swing back and forth, thereby driving the pressure piston to reciprocate. . The ultra-high pressure pump can maintain a stable output of ultra-high pressure liquid.

Description

technical field [0001] The invention relates to the field of engines, in particular to a high-pressure pump capable of maintaining stable output of high-pressure liquid. Background technique [0002] In the past, the ultra-high pressure pump used in the development of diesel fuel system was manual, and the output ultra-high pressure liquid can only be maintained for a short time, the pressure drops quickly, the pressure rises and falls quickly, and the fluctuation is very large. However, some fuel system research and development tests or tests require long-term stable ultra-high pressure liquid input, and the original manual ultra-high pressure pump can no longer meet the needs. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those...
