As China's coal industry has developed rapidly, enhancing coal production has become an important part, It's related to the operation of personnel,equipment safety and production efficiency. 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.
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 have conducted the breakdown diagnosis method research, through after several kind of main diagnosis method comparison proof, thinks the hard spectrum monitor method for the first choice method.
I have carried on the hard spectrum analysis to the hoisting main bearing oil type, formulated the sample standard and the main bearing condition criterion, and accompanied by the monitor example. Specially hard spectrum system spectrum parameter optimum composition. After several kind of common hard spectrometers, has chosen my school development the KTP-1 profiled iron spectrometer, unifies the domestic and foreign correlation datas to state the experience to recommend the value, has carried on the hard spectrum system spectrum parameter optimum composition experiment, obtains the relatively optimal fit experiment parameter value.
