【 Technology innovation 】 330 series exhaust fan bearing double cooling method optimization design modification - 2019 06 - 28 ( The river of qinghai aluminum co. , LTD. ) In the sweep of the modern society, the innovation, the technical reform is necessary for a stable and healthy development of enterprise, enterprise survival and development. Authors efficiency for the company, for stable operation of equipment, and burden for the employees, technology innovation, equipment reform hundred river person nature is not far behind, on June 6, 2018 hundred river in qinghai aluminum company purification workshop technical team design of smoke exhaust fan bearing double cooling system put into operation, double cooling system runs stably, greatly reduce the exhaust smoke fan bearing operating temperature, solves the troubled years of air bearing shaft temperature is high, the environment temperature influence big hidden trouble. Aluminum in July 2017 hundred river south factory purification system, technical and production equipment for the first high temperature period, the south factory purification system including 10 kv exhaust fan bearing adopts air cooling heat dissipation method, the thermal radiation to cool the air as a medium for heat exchange to achieve, so the heat exchange cooling efficiency is greatly influenced by environmental temperature, bearing the heat in the summer cooling speed is reduced, the temperature is high. In the summer of 2017, exhaust fan bearing operating temperature change with the temperature often close to the limit operating temperature, many times because of the high temperature forced fan switch, increase the unplanned and shut down the switch equipment, increase the bearing lubricating oil replacement frequency. Because there is no effective control measures to prevent abnormal equipment, workshop will special guards, staff on-site unattended monitoring, timely grasp the running status of equipment in real time in order to with the fastest speed response to appear abnormal. This monitor way lasted for nearly two months time, use our employees toil, persistence and high sense of responsibility for the safety of equipment of this period of time. Until you spend the hot weather everybody is relieved. The summer is over, but this year, in the future and how to deal with, is that right? You can't help but asked. The summer really haunt everyone, day and night, exhaustion of body and mind. On how to lower the temperature in the fan operation, solve so many problems caused by, cope with hot weather in summer is around the corner, in the future shop called for full participation, brainstorming, gathering cool way to measure, analyze and find the reason and put forward solutions, after discussion and argument of past eventually determine the fan bearing double cooling system design scheme, using the bearing oil chamber storage space, high thermal conductivity of copper tube plate into the snake shape into the bearing oil pool, the cooling water heat exchange cooling lubricant. Led by workshop technical backbone, all the maintenance class implementation, operation staff to cooperate. The accounting data, prepare materials, pipeline processing, the pipeline laying design, through the unremitting efforts of more than a month, work overtime in # 4 purification system to complete the first set of double cooling system, and in 2018 put into trial shipment by the end of June, running all aspects of the heat exchange cooling effect is good, to reduce the operating temperature of 20 ℃ design goal. And rapid advance of the technical renovation work, successively completed in # 5, # 6 purification system transformation, spent the summer of 2018, the hot weather, no equipment during the unscheduled shutdown, switch, oil changing work, each system fan bearings are not more than 60 ℃ temperature, system monitoring staff also did not like last year the left-behind, greatly reduces the system staff labor intensity. The technical renovation work received high evaluation, aluminium company up and down the river with the other group companies of the same problems in aluminium electrolysis fume purification system unit for the exchange of experience. At the same time, the technology innovation work in group of companies in the five small scientific and technological achievements appraisal recognised by the leaders of the group company and each expert, and equipment modification in group company class the third good grades, greatly aroused the staff's innovation, technological innovation enthusiasm. Have sprung up in the technical renovation work is not only a good a number of technical personnel, at the same time more gratifying is in the process of aroused everyone's consciousness, innovative consciousness and enterprising team cohesion and team spirit. The ancients Sun Quanzeng said: 'with all the force, is unmatched in the world. Can use all the wisdom, have no in sage. 'the great German writer Schopenhauer once said:' a single person is weak, just like drifting Robinson, only together with others, many to finish his career '. Yes the power of the team is no group, if you don't have this group of people together, our problem can not be solved so soon, is also likely to have been solved. Concentric mountain ChengYu, together to soil becomes gold. Success requires not only the tenacious perseverance, wisdom and inspiration, you also need to team cooperation spirit. A backwater never flush beautiful waves, only all rivers run into sea waves. Collective is the source of power, all is the cradle of wisdom, I believe that our group, in the future will do more brilliant achievements in work. The unity is strength, for the company and group to strive for a new piece of heaven and earth.
