The common failure analysis and elimination methods sanding machine

1, abrasive belt running deviation phenomenon. Cause analysis: the cause of this is generally because abrasive belt adjustment caused by the unreasonable, reasonable abrasive belt swing range should be controlled in 15 For 15-20 mm range, frequency 20 times per minute, if adjust unreasonable is prone to a long period of time running deviation phenomenon. Solution: adjust to a reasonable range. 2, limit failure condition. Harmful: limit failure will cause the abrasive belt ran side problems, easy to cause fire, so after limit failure problem must be timely solve. Solution: contact equipment maintenance repair or replacement as soon as possible. 3, abrasive belt rupture occurs. Cause analysis: 1, the long time use abrasive belt wear is too serious and cause the final fracture. 2, the processing parameters is not reasonable. Feed speed too fast, large amount of sand cut. Solution: change in time new abrasive belt, if there are unreasonable phenomena need timely processing parameters reasonably adjust. After 4, abrasive belt replaced sand cut size appear different phenomenon. Cause analysis: under normal circumstances change abrasive belt before and there is a certain deviation, reasonable range should be 0. Less than 5 mm, this reason is usually because of sanding machine cantilever lock Zhang Chidu are related. Solution: a reasonable adjustment, until the control to a reasonable range. 5, sand in the rising or falling tilt. Cause analysis: 1, the sand weight difference before and after large, imbalance. Before and after 2, 3, the oil cylinder of the internal friction check electricity, two two-way valve valve core is jammed elimination method: such as tilt caused by wonder need to correct immediately. 6, drive belt skid. The usual reasons: because caused by the improper adjustment. Solution: according to the belt elongation 1. 5 - 2% of the technical requirements, and do the belt on both sides of the tightness. After the completion of the adjustment to commissioning test, such as not completely solve so do adjustment again until solve.
