EMAG接箍车丝机电主轴液压静压环故障分析及处理

Failure Analysis and Disposal of Hydraulic Static Pressure Ring of Electric Spindle of EMAG Coupling Threading Machine

为了准确判断EMAG接箍车丝机主轴液压静压环故障原因,从静压环密封结构、设备冷却方式等方面对车丝机主轴套筒磨损及故障报警情况进行了具体分析,结合静压环拆卸过程的技术要点,整理出故障报警排查及故障处理方法。分析结果表明,长时间高温运行以及铁屑划伤是主轴静压环密封损坏的主要原因。建议在故障排除过程中,在静压环出口管路上增加节流阀,可以避免快速泄压导致的液压站温度升高及压力波动;同时在设备日常维护保养过程中,及时清理静压环附近铁屑,可大幅降低静压环系统的故障报警。

In order to accurately judge the failure cause of the hydraulic static pressure ring of the spindle of EMAG coupling threading machine,the wear and fault alarm of the spindle sleeve of the coupling thread machine are analyzed in detail from static pressure ring seal structure and equipment cooling mode,and the fault alarm troubleshooting and fault treatment methods are sorted out in combination with the static pressure ring disassembly process.The analysis results show that the main reasons for the seal damage are long-time high temperature operation and iron scraps scratch.It is suggested that in the process of troubleshooting,a throttle valve should be added to the outlet pipeline of the static pressure ring to avoid the temperature rise and pressure fluctuation of the hydraulic station caused by rapid pressure relief.In the process of equipment daily maintenance,timely cleaning iron scraps near the static pressure ring can greatly reduce the failure alarm of the static pressure ring system.
