当前位置:钢丝绳纤维芯生产注意事项
[来源:www.syuan-lab.com] [作者:aowl] [日期:18-08-03]
1、用混有再生棉纤维的黄麻绳芯生产制造一般用途钢丝绳。2、用混有黄麻麻纱的剑麻绳芯生产制造电梯、石油和天然气工业用钢丝绳。3、用再生棉纱充当绳芯生产细直径钢丝绳。4、纤维绳芯直径偏小时,合绳时用麻纱直接混进纤维绳芯。5、麻纱股、由股捻绳时捻距捻制随意放大,致使纤维绳芯支撑力不足。6、麻芯直径粗细差异大,直径细的地方对钢丝绳绳股难以形成有力支撑。7、钢丝绳实际承受的径向压力超出了纤维绳芯对股绳固有的支撑力,绳芯明显变细、股间隙消失是钢丝绳直径较标准规定值显著减小的直接原因。8、纤维绳芯浸油不充分,含油率低于要求,钢丝绳使用中绳芯油脂提前流失,几近干芯,致使钢丝绳用于斜井提升时,绳芯被碾碎,钢丝绳直接低于正常使用要求而被提前报废、更换。9、对进口的黄麻,局部腐蚀和腐烂变质部分不能实施有效剔除,捻制麻纱、股、绳芯径向破断拉力低于正常使用要求。10、过分强调钢丝绳表面的薄涂油,钢丝绳表面脂被加热的实际温度超过钢丝绳使用时能够承受的最高温度,纤维绳芯实际使用性能大幅度降低。 1. The general purpose wire rope is made of jute rope core mixed with regenerated cotton fiber. 2. Use the sisal hemp core made of jute hemp yarn to produce the wire rope for elevator, oil and natural gas industry. 3. Use regenerated cotton yarn as rope core to produce thin diameter wire rope. 4. The diameter of the fiber rope core is small, and when the rope is mixed, the yarns are directly mixed into the fiber core. 5. When the yarn is twisted, the ramp yarns will be magnified arbitrarily, resulting in insufficient supporting force of the core. 6. The diameter of hemp core is large and the diameter is thin. It is difficult to form strong support for wire rope strands. 7, the radial pressure that the wire rope actually bears is beyond the inherent supporting force of the fiber rope core to the rope. The thin rope core and the gap gap are the direct reasons for the decrease of the diameter of the wire rope compared with the standard value. 8, the fiber cord core is inadequately soaked, the oil content is lower than the requirement, the rope core oil is lost in advance and the core is nearly dry. The rope core is crushed when the wire rope is used for the inclined shaft, and the wire rope is directly discarded and replaced in advance. 9. For the imported jute, the partial corrosion and rotting metamorphic parts can not be effectively eliminated, and the twisting pulling force of twist yarn, strand and rope core is lower than that of normal use. 10. Overemphasizing the thin oil coating on the wire rope surface, the actual temperature of the surface grease of the wire rope is higher than that of the wire rope, and the actual performance of the fiber rope core is greatly reduced.
