我厂1985年从意大利引进了地毯长丝纺丝机 1套,1986年投入生产。设备各工位的牵伸定型和长丝卷绕辊悬臂旋转,辊径与臂长比达1∶10,转速较高,每分钟分别为2300和4300转以上。设备安装时,逐辊进行动平衡复校,径向跳动限制在0.02毫米以下。 多年来,温度传感器、感应加热器、热电阻因损坏而更换时,要拆装各工位的牵伸辊;为补偿尼龙涨块的磨损,更换弹簧及清洗润滑,又须拆装卷绕辊,造成径向跳动加剧。其后果为:轴承容易损坏,产生毛丝,降低长丝质量;引起机身震动,降低车速,减少产量。
I plant in 1985 from Italy introduced a carpet filament spinning machine, put into production in 1986. Equipment drawing and shaping of various stations and filament winding roller cantilever rotation, roller diameter and arm length ratio of 1:10, high speed, respectively, 2300 and 4300 rpm per minute or more. Equipment installation, by roll balancing for correction, radial runout limited to 0.02 mm below. Over the years, temperature sensors, induction heaters, thermal resistance damaged due to replacement, to disassemble the station of the draft roller; To compensate for the nylon uplift block wear, replacement of springs and cleaning lubrication, but also to be disassembled winding roller , Resulting in increased radial runout. The consequences are: bearings are easily damaged, resulting in bristles, reducing the quality of the filaments; causing body vibration, reducing speed, reducing output.
