Abstract

A variable frequency hydraulic pipe network type excitation device, comprising a hydraulic pump station, an excitation system and a variable frequency control system, wherein the device enables a fluid-filled pipe with an elastic support to vibrate through a hydraulic shock wave generated by a shock wave machine, so that a vibrated pipe network is used as an execution mechanism of the vibration to drive a vibration facility to vibrate. The variable frequency hydraulic pipe network type excitation device provided by the invention reduces the vibration quality and improves the efficiency of a hydraulic system, and the vibration parameter adjustment is more convenient, and the device can be matched with a vibrating screen to sieve and drain the mineral.

Description

technical field [0001] The invention relates to a hydraulic vibration excitation device, especially a hydraulic vibration excitation force generated by a vibrating oil cylinder, a hydraulic vibration excitation wave generated by a shock wave device, and the amplitude and frequency of the pipe network adjusted and controlled by an overflow valve and a frequency converter. A frequency conversion hydraulic pipe network type vibration device. Background technique [0002] The vibration excitation method of the existing commonly used vibration equipment is mainly based on the inertial excitation method. The inertial excitation method relies on rotation to generate centrifugal force and periodically changes the excitation force in a certain linear direction. At the same time, there is also a centrifugal force in the non-vibration direction. This part of the force not only consumes energy in vain, but also has adverse effects on the vibration machinery itself, especially with the d...
