Abstract

The invention discloses a seat plate hydraulic system with a pressure feedback type adjustable flow valve. The system comprises a two-position two-way proportional reversing valve, an electromagnetic ball valve, a seat plate oil cylinder, an adjustable flow valve and a seat plate accumulator; When the self-adaptive seat plate is working, the pressure of the seat plate accumulator is fed back to the adjustable flow valve through the oil circuit, and the opening of the throttle valve is dynamically adjusted according to the pressure of the seat plate accumulator, so as to realize the rapid lifting control of the seat plate cylinder. The present invention is beneficial to improve the shortcoming of long lifting time of the fixed orifice seat plate, and can significantly improve the working efficiency of the equipment.

Description

technical field [0001] The invention belongs to the field of fluid transmission and control, in particular to a seat plate hydraulic system with a pressure feedback type adjustable flow valve. Background technique [0002] The hydraulically driven seat and pan system is widely used in large construction machinery with large bearing capacity. Its working principle is to resist the impact load through hydraulic resistance and provide stable and effective support for the working platform. At present, the commonly used hydraulic system of seat plate often adopts fixed orifice, which cannot adaptively adjust the opening of the orifice according to the pressure. In addition, the orifice is generally designed according to the hydraulic resistance requirements when the seat pan is completely lowered, so the size of the orifice is small and the design is more conservative, resulting in lower efficiency of retracting and lowering the seat pan, especially in the process of retracting a...
