Technology | large vertical mill reducer fault maintenance
Large vertical mill is widely used in modern cement industry and the maintenance of its supporting components is related to the normal production of vertical mill. The large reducer supporting the vertical mill should be included in this column. Once an accident occurs, the site maintenance is difficult, the technical content is high, and the maintenance cycle is long, which has a great impact on the normal production and operation of enterprises. Many cement enterprises' response measures are: to spend high costs to purchase spare machine, in case of a rainy day; Or the use of winter peak stop production opportunities, the machine back to the factory maintenance, is bound to spend high back and forth transportation costs. This shows that the on-site inspection and maintenance method of large reducer is very important.

Professional inspection: Device inspection is the most important method to discover potential faults.
Common faults: high speed shaft bearing damage, high speed shaft bevel gear tooth broken, high speed shaft two bearings between the interval sleeve loose, parallel axis external tooth spline shaft and internal tooth spline sleeve surface wear, equipment vibration
Common faults: high speed shaft bearing damage, high speed shaft bevel gear tooth broken, high speed shaft two bearings between the interval sleeve loose, parallel axis external tooth spline shaft and internal tooth spline sleeve surface wear, equipment vibration
Fault maintenance: invite professional reducer maintenance team to enter the factory, selectively carry out on-site maintenance and return to the factory maintenance, reducer foundation shaking treatment
