成品车间供尿素装袋机用气的离心叶片式空气压缩机,在处理轴端漏油时,由于半联轴器的轴套部分磨损较大,安装时对中性差,致使开车运转产生别劲,将浮动密封环及联轴器轴套拉裂,后将压缩机拆卸检修,采用测绘的备件图加工联轴器及浮动密封环更换,在试车时将浮动环烧坏变形与密封座涨紧连在一起,只得又拆下。由于铸铁的密封座内孔拉毛较严重,若加工新的、工艺较复杂,周期较长。将密封座的内孔尺寸加大后,提高表面光洁度,同时相应加大浮动环外圆尺寸,进行装配后,在进行试车时又将联轴器轴套与浮动密封环粘连。这样对照图纸对连续烧坏浮动环的原因进行了认真分析,并更换了浮动环与联轴器套的材料,更换了喷油嘴,再次试车才乎合要求,使瘫痪了几个月之久的空压机恢复正常运转。
Finished workshop for urea bagging machine Centrifugal blade air compressor gas, oil leakage in the treatment of the shaft end, due to the larger part of the sleeve shaft coupling wear and tear, poor neutral installation, resulting in driving force , The floating seal ring and coupling shaft sleeve cracked, the compressor disassembly and maintenance, the use of mapping spare parts machining coupling and floating seal ring replacement, the test will float ring deformation and sealing seat up tight Even together, only to be removed. As the cast iron sealing seat hole hair more serious, if the processing of new, more complex processes, longer cycle. Increase the size of the inner hole of the seal seat to improve the surface finish, and at the same time increase the size of the outer surface of the floating ring. After the assembly, the coupling sleeve and the floating seal ring are stuck together during the test. This control drawings of the reasons for the continuous burnout of the floating ring was carefully analyzed and replaced the floating ring and the coupling sleeve of the material, the replacement of the nozzle, the test again to meet the requirements of the test, so paralyzed for several months Air compressor to resume normal operation.
