一种液控高速液压转换装置及其使用方法
By designing a hydraulically controlled high-speed hydraulic conversion device, and utilizing pistons and elastic components to control the rapid movement of the valve core, rapid switching between high and low pressure oil in a No. 3 jet fuel environment with a medium viscosity of 1.2 mm²/s was achieved. This solved the problem of excessively long conversion time in existing technologies and met the needs of rapid change testing.

AI Technical Summary
The existing hydraulic switching device cannot achieve rapid high-low pressure switching in the environment of No. 3 jet fuel with low medium viscosity, and the switching time of the existing equipment is too long, which cannot meet the requirements of rapid change test within 20ms.
A high-speed hydraulic switching device with hydraulic control was designed. By utilizing the cooperation of piston and elastic element, the valve core is rapidly moved by controlling the pressure difference between the control chamber and valve chamber and the elastic force, so as to achieve precise switching between high and low pressure oil ports and output oil ports, and the switching time is controlled within 20ms.
It enables rapid switching between high and low pressure oil in No. 3 jet fuel environment with a medium viscosity of 1.2 mm2/s, with a switching time of no more than 10 ms, meeting the requirements of rapid change test and improving work efficiency and ease of operation.
