Flywheel energy-accumulating energy-saving-type hydraulic vibration system

Abstract

The invention discloses a flywheel energy-accumulating energy-saving-type hydraulic vibration system, and belongs to the technical field of hydraulic vibration. In the system, a motor is connected with a flywheel through a hydraulic coupler; the flywheel is connected with a double hydraulic pump through an elastic coupling; the hydraulic pump and a hydraulic cylinder form an enclosed-type loop through a hydraulic valve; the hydraulic cylinder is connected with a vibration body, wherein the double pump has two working conditions of double-pump operation and single-pump operation; and when in double-pump operation, the output flow rate of the pump is increased, the hydraulic cylinder and the vibration body accelerate, and when in single-pump operation, the flow rate of the pump is decreased, the hydraulic cylinder drives the hydraulic pump depending on inertia to drive the flywheel to speed up, and the vibration body slows down. The flywheel energy-accumulating energy-saving-type hydraulic vibration system provided by the invention has the characteristics that the variation of the vibration body momentum is mainly realized through the momentum exchange between the flywheel and the vibration body. The momentum exchange is reversible and has no real power consumption, thus the flywheel energy-accumulating energy-saving-type hydraulic vibration system saves energy compared with the existing throttling speed-regulating-type hydraulic vibration system.

Description

technical field [0001] The invention relates to a flywheel energy storage and energy-saving hydraulic vibration system, which belongs to the technical field of hydraulic vibration. Background technique [0002] Vibration technology is a basic technology widely used in various industrial fields. Vibration methods mainly include three categories: mechanical, electric and hydraulic. The main advantage of hydraulic excitation is that it can generate larger excitation force and displacement amplitude. The exciting force of a large hydraulic vibration table can reach hundreds of tons, and the displacement amplitude can reach tens of centimeters. This feature just makes up for the shortcomings of mechanical and electric vibration methods, and meets the needs of large-tonnage vibration equipment in the fields of aerospace, automobiles, shipbuilding, and metallurgy. In addition, the force density and power density of the hydraulic vibration system are relatively large, and the vib...
