A vibrating screen fault intelligent diagnosis device and diagnosis method

Abstract

The invention discloses a vibrating screen fault intelligent diagnosis device and a vibrating screen fault intelligent diagnosis method using the device. The device includes an equipment hardware part and a diagnosis processing part, wherein the equipment hardware part includes a plurality of data sets arranged on the vibrating screen to be tested. A collector and a host computer signally connected to the data collector, the diagnosis processing part includes a data acquisition module integrated in the data collector and a host module integrated in the host. Through the collection of attitude data and vibration data, the invention makes the subsequent fault diagnosis results more accurate, and can diagnose the faults of key components in the vibrating screen more comprehensively and earlier, and reduce production and damage caused by component damage. equipment loss.

Description

technical field [0001] The invention relates to a fault diagnosis device and a corresponding diagnosis method, in particular, to an intelligent diagnosis device and a diagnosis method for a vibration screen fault, belonging to the technical field of the industrial Internet. Background technique [0002] In the mineral processing industry, the vibrating screen is a common and very critical equipment. In terms of its working principle, the vibrating screen mainly drives the screen box to reciprocate through the exciter, so as to realize the screening of materials. [0003] Due to the particularity of the operation scene in the mineral processing industry, in the actual application process, the vibrating screen will be in a state of load operation for a long time, and it is easy to cause screen wear, fixed bolt breakage, vibration isolation spring breakage, bearing damage and other faults, which will lead to screen wear and tear. The sub-efficiency is greatly reduced and the op...

Problems solved by technology

In actual application scenarios, the acceleration data will be affected by factors such as load and exciting force. Therefore, although the above scheme can achieve certain diagnostic results, it is difficult to ensure the monitoring data because it only monitors the acceleration of the spring part of the vibrating screen. and the accuracy of the diagnosis

In addition, potential faults such as phase changes caused by screen damage and other reasons are difficult to be accurately diagnosed through the above scheme
