         近期，广西华银铝业公司矿山部组织精干人员陆续对排泥加压站一、二级泵进行轴承技改，有效解决了轴承寿命过短、故障频发难题，取得重大突破，胶体磨实现降本提质目标，为矿山的顺利生产以及提产提供有力保障。　

　　　据了解，矿山部排泥加压站是矿山生产流程中重要的一环。供水设备洗矿泥浆经浓密机浓缩后，再经三级排泥泵加压，输送至4.5公里外的尾矿库。近几个月来，一、二级泵四点角接触球轴承故障频发，主要表现为保持架断裂或滚珠磨蚀、破裂，液下泵平均寿命仅200多台时。据统计，年初至今共更换18次，大于前两年轴承检修总和。由于轴承过早“夭折”，进一步加快泵轴、机封损坏速度，耗费大量人力、物力进行维修更换。随着水泵控制柜矿山部提产在即，解决排泥加压泵轴承寿命短问题迫在眉睫。

　　　　鉴于以上情况，矿山部积极采取有力措施，潜水泵 组织技术人员进行攻关，不断创新工作方法，用两盘圆锥滚子轴承代替故障频发的一盘四点角接触球轴承，双列轴承背靠背安装后与原来的NU224M轴承配合使用，三盘轴承替代原先的两盘轴承使用。技改后，一、二级排泥加压泵运行平稳，震动、跳动幅度明显减小，至今已运行500多台时，未出现异常状况。

         Recently, the Department of Guangxi Huayin Aluminum Company of organizations capable personnel mines on the mud pressure points one after another, two pump bearings technical innovation, effective solution to the bearing life is too short, frequent breakdown problems, a major breakthrough and achieve cost reduction and quality and goals for theScrew pumps smooth production and raise mine production provide strong protection. It is understood that the Department of sludge mine mine production process pressure station is an important part.Magnetic pumps Through thick mud washing machine concentrated, and then by three mud pump pressure, transmission to 4.5 km away, the tailings. In recent months, one, two pump four-point angular contact ball bearing fault frequently, mainly for the ball cage fracture or abrasion, fracture, life expectancy is only when moreSelf-priming pumps than 200. According to statistics, the replacement of 18 so far this year, more than the sum of two years ago bearing maintenance. As the bearing premature "mortality", and further speed up the pump, mechanical seal damage speed, consuming a lot of manpower and material Suber-water pumpsresources for maintenance and replacement. As soon yield the Ministry of Mines to address the mud pump pressure bearing short life are imperative. In the circumstances, the Department of Mines to take effective measures to actively organize technicians to research, innovative methods of work, with two tapered roller bearings instead of the Chemical pumpsfrequent failure of a four-point angular contact ball bearings, double row bearings back to back after installation The original NU224M bearing with the use of three bearings replace the previous two bearings. Technological transformation, the secondary pressure pump sludge to run smooth, vibration, beating rates were significantly reduced, has been running more than 500 in Taiwan, the situation is not abnormal.
