五、电梯专用选型与维保要点
- 选型匹配要求
- 绳径与曳引轮直径比需满足 d/D ≤ 1/40（符合 GB 7588-2020 标准要求），重载电梯建议提升至 1/45，避免绳体过度弯曲导致疲劳断丝
- 槽型匹配：10~14mm 绳径适配深 U 型槽，18mm 绳径适配梯形槽，提升曳引力，杜绝中速重载运行打滑风险
- 严禁用通用 9×19S-CSC 替代电梯专用型号，两者耐疲劳性能、抗旋转性能差异显著
- 维保关键事项
- 润滑管理：仅可使用电梯专用重载抗尘曳引脂，禁止使用普通钢丝绳润滑脂（易流失、导致干磨）；脂层厚度保持 0.25~0.35mm，补脂周期建议为 8 个月 / 次
- 报废判定：出现以下情况立即更换（符合 GB 8903-2018）：① 单股断丝数≥2 根；② 绳径磨损≥4%；③ 钢丝绳出现锈蚀、变形、松股、跳丝
- 更换周期：建议每 6~8 年强制更换（或运行里程达 70 万 km），工业电梯换绳需先清空轿厢负载，避免绳体过载损伤

Q
What kind of lubricant can prevent wire rope damage?
A
First, the smooth oil has good fluidity and soaking ability, allowing it to quickly enter the inside of the rope and the rope core when the wire rope is smooth pretreated, and can play a role in preventing bacteria from multiplying inside the rope core fibers.
Second, the lubricating oil adhered to the wire rope will not be easily wiped off, and the smoothing effect will not be affected within the specified temperature range. In addition, the lubricating oil with adhesive function can also prevent skid, which provides assistance for the friction of the elevator wire rope.
Third, it has a high oil film strength, which can resist the extremely high pressure between the steel wires in contact with each other under extremely heavy load, and can also resist decomposition and transformation.
Fourth, smooth oil has high cohesion, which can avoid the dripping of smooth oil, centrifugal loss when there is no exercise, and avoid grease waste and pollution to other equipment.
Fifth, it does not contain ingredients that can cause corrosion and rust in the steel wire rope, and the effect of anti-corrosion and anti-rust is better.
Sixth, its self-correcting ability is strong. When the wire rope is used, it constantly twists and turns, which will cause the surface oil film to continuously knead and expand. This requires a soft and high-temperature oil film to maintain the rope body from cracking.
