'Listening, asking and 'four it, belt running safety

'Listening, asking and 'four it, belt running safety - 2019 11 - 24 people often describe these jobs' play around tight Turner, fitter, slow dry electrician. 'Turner fast hands, fitter, pay attention to fire makes sweet malt electrician is naughty words to play, to play but no, otherwise the electrical equipment must have an accident. In fact, every kind of work has its own characteristics and specific requirements alone. Specific to the underground belt repair this piece, due to the underground scene environment is different from the ground, high humidity, dust, equipment continuous operation time is long, having once more shipments will affect the characteristics of the production, therefore, belt maintenance man to do the 'd' in the former, 'repair' behind. Timely find problems and timely solve the problems and timely maintenance equipment, nip in the bud, to ensure trouble-free operation. Don't have guns unpleasant feeling the light. If holding assault, by luck, luck working attitude to dry, equipment 'unhappiness not only, not only will be a big failure, by that time, busy to, blowing his beard also upset them useless. Dry belt maintenance over the years, I gradually come to the conclusion that a set of effective methods, the Chinese medicine 'listening, asking and four it into use in the maintenance, good results have been achieved, to share my experience with friends now. One, belt maintenance 'at first,' look at 'word, is the precondition of good belt maintenance. Belt driven equipment, rotating drum is normal or not, roller is damaged, whether belt running deflection, all want to rely on to find out in the inspection. Some hidden fault, alone is not enough, also need to harness using other methods to found the problem. In a word, some of the equipment failure, may not be found, don't look at was never found, this is a basic principle. Dry belt maintenance equipment inspection, therefore, is the first, to do the legs to the eye, heart, hand to, only in this way, the device can nip in the bud, trouble-free running safety. Some maintenance workers attitude blundering, do work anyway, when the equipment inspection tour, jigsaw, what also can't find, equal to did not look. Some people lack of experience, can't make qualitative judgment of equipment phenomenon, or misjudgment, see a is equal to the blind. This is not desirable. Accurate method is in daily inspection should XinXiRuFa already, and penetrative. So a critical how to practice? Only see, frequently look, look. Key equipment look closely, weak equipment often watch, vulnerable equipment repeatedly see, see more, practice makes perfect, experience is accumulated. Second, the maintenance of belt 'smell' 'smell' has two meanings, one is with nose to smell, it is listening with ears. Single underground odor, equipment abnormal smell, such as electrical equipment overheating of enameled wire, belt scraping rubber smell, when far apart can smell. When will have this kind of taste, must be in in the first point to check, if you need downtime, immediately stop, avoid failure or expanded. Three, belt maintenance 'to' bearing belt in each department, is unable to see with the eye, can borrow listening good method to check for it. On the premise of comply with the safety rules, the listening bar on bearing pedestal check the stand or fall of bearing, if it is a 'buzz' voice, bearing in good condition; 'Buzzing' sound with 'rustling sound, bearing aging; If it is' la-la-la 'or' click 'sound, Pal, here is your big problem, to change the bearing! Four, belt maintenance diagnosis of 'pulse' old doctor of traditional Chinese medicine the doctor felt her pulse love, even headaches brain hot, he also want to hold your mission to touch. Can look quite funny, but to use on the belt equipment inspection, it was not a bit silly. Bearing easy fever, above a certain temperature, bearing grease decomposition in metamorphism, bearing damage easily. When inspection, can by hand touch bearing end cover, we can know the temperature change of bearing. In the same way, also can to slow connection device for testing of the equipment. Five, belt maintenance diagnosis' q 'belt device fails, will influence the coal production, how in the shortest possible time to eliminate malfunction maintenance personnel, to restore equipment running, this is the belt maintenance man most likely to run into problems. This time, the guy is most prone to impatience, came to the scene what all don't know, are, raise my hand is dry. Such not only easy to pose a safety hazard, which is dangerous to people, sometimes because of improper operation, will also cause secondary damage to equipment, increase the difficulty that the equipment processing, physical strength is the wasted effort, and delay time in vain. The troubleshooting time is precious, but the guy should like to see the doctor of traditional Chinese medicine, to ask for details of site operation staff, detailed understanding of equipment failure phenomenon, cutting wood and tool dresser. Because they are the first scene, have a intuitive impression on equipment failure phenomenon. Mechanic is only preliminary understanding the cause of the problem, the equipment failure after a general judgment, and then according to their experience, ideas, to equipment failure rule out step by step. This saves maintenance time, and can completely troubleshooting, to achieve the effect of the wasted effort. Of course, if you want to do a good belt and maintenance work, only by these methods are not enough. With a line, loves a line, drill a line, a line of spirit to learn, learn on the job, increasing in the study, only in this way, can do a good belt and maintenance work, be a qualified mechanic. （ Source: China coal network)
