Embodiment Construction

[0032] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0033] The implementation of the present invention will be described in detail below in conjunction with specific embodiments,

[0034] like figure 1 As shown, in an embodiment of the present invention, a fault diagnosis method for a transmission mechanism of a motor load is provided, which includes steps S1-S6, which will be described in detail below.

[0035] Step S1: the motor is started.

[0036] Collect the voltage and current data of the motor in real time. When the effective value of the current sampling value is greater than 0.05 times the rated current of the motor, it is judged...

Abstract

The invention provides a fault diagnosis method and system for a transmission mechanism of a motor load. The method comprises the following steps: acquiring voltage and current signals of a motor of a periodic working system in a period; calculating an active power curve in the period according to the collected voltage and current signals; and comparing and analyzing the active power curve in the period with a historical active power curve, and judging whether the transmission mechanism of the motor load has a fault or not according to a comparison and analysis result. By adopting the technical scheme of the invention, health monitoring can be efficiently carried out on the transmission mechanism loaded by the motor, operation and maintenance personnel can be scientifically guided to timely arrange a shutdown overhaul and maintenance plan, the production efficiency is improved, and the equipment operation and maintenance cost is reduced.

Description

technical field [0001] The invention relates to the field of motor fault diagnosis, in particular to a fault diagnosis method and system for a motor load transmission mechanism. Background technique [0002] Electric motors are widely used in power generation, chemical industry, shipbuilding, steel, cement and other industrial fields. Whether it is an asynchronous motor or a servo motor, the load is generally a screw mechanism, a synchronous pulley mechanism, a rack and pinion structure, a disc structure, and a long arm structure. Wait. These transmission mechanisms or operating mechanisms work in various complex environments for a long time, and their shaft pins, gears, chains and other transmission parts lack lubrication and are prone to fatigue and wear. After running for a period of time, the mechanical mechanism often occurs. , refusal to move, etc. It is easy to cause the electric operating mechanism to be insensitive in its stroke, the transmission gear to be broken...
