Universal grinder clogged grinder use one of the fault, there may be problems in equipment design, but more due to the use of improper operation.
(A) universal grinder feed too fast, the load increases, causing blockage. Feed, it is necessary to pay attention to the ammeter pointer deflection, if you exceed the rated current, indicating that the motor overload, overload for a long time, will burn out the motor. The emergence of this situation should immediately reduce or close to universal grinder hopper, you can also change the way of the feed by adding feeders to control the feed rate. Manual, automatic two feeders, the user should choose the right feeder according to the actual situation. Universal grinder speed, load, and load fluctuations. Therefore, the current universal grinder work is generally controlled at about 85% of the rated current.
(B) the discharge pipe poor or blockage of the feed too fast, make universal grinder outlet to plug; mismatch and transportation equipment will result in the discharge pipe wind weakened or no wind after blocked. Clear through the send port change does not match the delivery of equipment to detect failure to adjust into the feed rate, the normal operation of equipment.
(C) universal grinder hammer clips, aging, the closure of mesh holes, broken, crushed material moisture content is too high will make universal grinder blocked. Broken and badly aging hammer should be regularly updated to maintain the universal grinder in good working condition, and regularly check the screen, the crushed material moisture should be less than 14%, thereby enhancing production efficiency, but also the universal grinder congestion, enhance the reliability of the grinder work.
(D) universal grinder 2 bearing rugged rotor and shredder rotor misalignment, make additional load bearing by the impact, causing bearing overheating. This happens, immediately stop troubleshooting, to avoid damage to bearing early.
(E) universal grinder bearing lubricant too much, too little or aging is caused by the bearings to overheat and damage the main reason, therefore, be according to use the book requires time quantitative filling oil, general lubrication accounting for bearing space 70% -80% too much or too little is not conducive to bearing lubrication and heat transfer. Bearings to extend their useful life.
(F) universal grinder bearing cap and shaft with tight, bearings and shaft with too tight or too loose will lead to bearing overheating. Once this occurs, equipment operation, we will send the friction sound and swing. Should be down to remove the bearings. Dressing friction parts, and then reassembled as required.
(G) bearing overheated bearing is more important universal grinder parts, and its performance directly affects the normal operation of the universal grinder and production efficiency. Equipment during the operation, the user should pay special attention to the bearing temperature rise and noise of the bearing parts of the abnormal early. |
