Mechanical equipment fault diagnosis device capable of detecting vibration frequency

Abstract

The invention relates to a mechanical equipment fault diagnosis device capable of detecting the vibration frequency. The mechanical equipment fault diagnosis device comprises a machine body and a display screen, wherein open grooves are distributed in two sides of an outer wall of the machine body; a cover body is distributed outside the open grooves; an inner sliding rail is distributed at the connected part of the cover body and the machine body; a handle is arranged at the middle part of one side of the cover body; the display screen is distributed at one side of the front side of the machine body; an operation panel is arranged at the other side of the front side of the machine body; a limiting pad is fixed at one end of the outer wall of the machine body; and a PCB is fixed in the display screen. Through the arrangement of the machine body, the open grooves and the cover body, a sliding structure is formed between the machine body and the cover body through the open grooves, and an obtuse angle design is adopted by the outer surface of the whole machine body, so that when a user holds the device, no sharp part exists at the corner of the device and the condition that the useris scratched is avoided; and furthermore, the cover body has a good protection effect and can effectively protect the front side of the machine body, thereby reducing the possibility of damage to themachine body in the carrying process.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment fault detection, in particular to a mechanical equipment fault diagnosis device capable of detecting vibration frequency. Background technique [0002] Mechanical fault diagnosis is a technology to understand and master the state of the machine during operation, to determine its overall or partial normal or abnormal, to detect faults and their causes early, and to predict the development trend of faults. Oil monitoring, vibration monitoring, noise monitoring , performance trend analysis and non-destructive flaw detection are the main diagnostic techniques. A well-designed machine has a low natural vibration level, but when the machine wears, the foundation sinks, and the components deform, the dynamics of the machine Performance starts to change in all sorts of small ways: shafts become misaligned, components start to wear, rotors become unbalanced, gaps increase, all of these factors...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a mechanical equipment fault diagnosis device that can detect the vibration frequency, so as to solve the problem that the existing fault diagnosis device proposed in the above background technology has no frequency amplification equipment during use, resulting in too small vibration amplitude. Misjudgment is easy to occur, and there is no good defense device in use, which leads to the problem that the fault diagnosis device is prone to damage
