AI Technical Summary

Technical Problem

In traditional hydraulic systems, high-speed switching valves have large installation space, many pipe joints, high leakage risk, and low efficiency, making it difficult to achieve high-frequency on-off switching.

Method used

The switching inertia unit of dual high-speed switching valve is adopted. The valve core is driven by rotating inertia elements and stepper motor to realize PWM adjustment, reduce pipeline connection, and use the inner hole of the valve block instead of the external pipeline to simplify installation and disassembly and improve system stability sex.

Benefits of technology

It significantly reduces the space area of ​​the hydraulic adjustment device, reduces oil leakage, improves system stability and efficiency, and achieves precise control and adaptation to load flow and load pressure.

Abstract

The invention provides a switch inertia unit with double high-speed switch rotary valves and an adjusting method and device. The switch inertia unit comprises a rotary inertia element, a front high-speed switch rotary valve, a rear high-speed switch rotary valve, a driving gear, a rotating speed sensor, a front gear and a rear gear. The output end of the rotary inertia element is connected with the middle part of the driving gear; and the rear high-speed switch rotary valve and the front high-speed switch rotary valve are respectively connected with the mounting end of the valve block. The driving gear is in meshed connection with the rear gear and the front gear, the middle of the rear gear and the middle of the front gear are connected with the first end of the rear high-speed switch rotary valve and the first end of the front high-speed switch rotary valve respectively, and the rotating speed sensor is located at the upper end of the middle of the rear gear and the upper end of the middle of the front gear. The switch inertia unit is double pulse width modulation, the front high-speed switch rotary valve controls the rotating speed of the rotating inertia element, the rear high-speed switch rotary valve controls the output load flow, and then adaptation to load pressure change and power tracking of the load are achieved.
