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 same. The device comprises an equipment hardware part and a diagnosis processing part, wherein the equipment hardware part comprises a plurality of data collectors disposed on a tested vibrating screen and a host in signal connection with the data collectors; and the diagnosis processing part comprises a data acquisition module integrated in the data acquisition unit and a host module integrated in the host. According to the device, through acquisition of attitude data and vibration data, subsequent fault diagnosis results are more accurate, faults of key components in the vibrating screen can be diagnosed more comprehensively and earlier, and production and equipment losses caused by component damage are reduced.

Description

technical field [0001] The invention relates to a fault diagnosis device and a corresponding diagnosis method thereof, in particular to an intelligent fault diagnosis device and a diagnosis method of a vibrating screen, which belong 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. As far as its working principle is concerned, 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 of the mineral processing industry, in the actual application process, the vibrating screen will be in the state of load operation for a long time, and it is easy to have screen wear, fixing bolt breakage, vibration isolation spring breakage, bearing damage and other faults, which will lead to screen failure. The drastic reduction of the sep...

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
