Abstract

The invention discloses a digital switching type inertial hydraulic converter and a working method thereof. The digital switching type inertial hydraulic converter comprises an energy accumulator, a liquid sensor end cover, a valve body, a single action hydraulic cylinder, pilot high speed on-off valves, a two-position three-way high-speed on-off valve, a rotary flow distributing valve, a shaft coupling and a driving motor; isolating and pressurizing functions of high and low pressure oil liquids are realized by driving the parts, such as the rotary flow distributing valve, a centrifugal pressurizing disc and a flow distributing disc, by using a driving motor; the on-off function of the high and low pressure oil liquids is realized by independent switching control of the two pilot high speed on-off valves; the functions of accelerating the flow of high pressure oil liquid in a spiral type compact liquid sensing pipeline and sucking low pressure oil liquid under force are realized by forming the spiral type compact liquid sensing pipeline through interference fit of a spiral liquid sensing pipe and an outer sleeve; according to the hydraulic converter in the form, the hydraulic workefficiency is greatly improved; the adaptability is high; the reliability is high; and an electro-hydraulic proportional hydraulic control system with high energy consumption and poor anti-pollutioncapacity is expected to be replaced.

Description

technical field [0001] The invention belongs to the technical field of fluid transmission and control, and relates to a digital switch type inertia hydraulic converter and a working method thereof. Background technique [0002] Fluid transmission and control technology has been developed for more than 70 years, and is widely used in important military equipment fields such as aerospace, ships, artillery and missiles. With the guidance of national energy conservation and emission reduction policies, high-efficiency electric transmission has gradually replaced fluid transmission and control technology in the low-power category, but at higher power, fluid transmission and control technology is still difficult to replace due to its high power density ratio. Therefore, improving the efficiency of fluid transmission and control technology has become an urgent problem to be solved. The average working efficiency of traditional hydraulic components and systems at the expense of thr...
