Recently, Guangxi Huayin Aluminum Corporation Mine Organization capable personnel have one or two stage sludge pressurization station bearing technical transformation, effectively solve the bearing life is too short, frequent problems of failure, made major breakthroughs, to achieve cost-effective Quality objectives, for the smooth production of mines and to provide strong protection. It is understood that the Ministry of Mines sludge pressurization station is an important part of the mine production process. Slurry washing slurry concentrated by the thickener, and then by three sludge pump pressure, transported to the tailings 4.5 km away. In recent months, one, two pump four point angular contact ball bearings frequent faults, mainly for cage fracture or ball abrasion, rupture, the average life expectancy is only more than 200 units. According to statistics, the beginning of the year so far replaced a total of 18 times, greater than the sum of the previous two years bearing inspection. As the bearing premature "premature death" to further speed up the pump shaft, seal damage speed, cost a lot of manpower and material resources for maintenance and replacement. As the mining ministry is about to come to an end, it is imminent to solve the problem of short life of the sludge pump. In view of the above, the Ministry of Mines to take effective measures to organize technical personnel to tackle key issues, innovative methods of work, with two tapered roller bearings instead of a frequent fault of a four-point angular contact ball bearings, double row bearing back to back mounting The original NU224M bearing with the use of three bearings instead of the original two bearings to use. After the technical innovation, the first and second sludge discharge pumps run smoothly, and the amplitude of vibration and beating is obviously reduced. Up to now, more than 500 units have been operated without abnormalities. More Search Keywords : Pumps
