The coal mine hoisting technique is in the mine pit transportation pharynx and larynx equipment, is communicates about the mine pit. Its running status quality produces the vital role to the coal mine safety. The practice indicated the hoisting technique breakdown creates the situation which the production loses to sometimes occur. Therefore, to its development breakdown diagnosis and the condition monitor maintenance work is extremely essential.
This text can lead the introduction to diagnose the method to mechanical trouble and found out to be applicable to mineral well to promote the diagnosis method of break down of the machine each part. Electromagnetism examination method, vibration examination method, and iron table analysis method, but for promote machine to say, isn't a kind of method enough. Sometimes need to carry on a comprehensive examination with various methods, prevent from with diagnosis breakdown of creation, avoid important event thus past of occurrence.
In the article, the hoisting common breakdown phenomenon has been analyzed, through carries on the lubrication and the attrition state analysis after the hoisting main bearing, discovered the existence serious attrition phenomenon, thought is adding the deboost phase especially, should carry on the breakdown diagnosis and the condition monitor to the hoisting. Proposed the condition monitor service necessity, and compares the condition monitor service with other monitor method, obtains the condition monitor service the superiority to be at. I conducted a method of fault diagnosis, that Ferrography monitoring methodologies for effective method.
