    二、电梯专用核心技术参数

    参数项详细说明
    结构组成8 个西鲁式压实外层股 + 独立钢丝绳芯;采用外层右捻 + 绳芯左捻的交叉捻工艺,旋转稳定性满足电梯曳引绳低扭转要求
    钢丝材质电梯专用特级高碳钢(#82B 精炼级),抗拉强度波动≤30MPa,屈强比≥0.92,耐疲劳次数≥3.2×10⁶次(弯曲半径 D=8d),远超通用钢丝绳标准
    表面处理1.  镀锌磷化复合处理:先磷化(增强润滑脂吸附性)后热镀锌(镀层厚 25~38μm),防锈耐磨,适配潮湿机房、半户外电梯
    2.  光面浸电梯专用曳引脂:涂覆高粘附性、低噪音曳引脂,摩擦系数稳定在 0.08~0.09,减少曳引轮磨损与运行噪音
    3.  电镀锌:仅适用于干燥无尘机房的低速杂物电梯
    直径范围常见 6~12mm(中低速电梯主流规格),适配曳引轮半圆槽、浅 U 型槽
    公称抗拉强度1770MPa(电梯专用优选等级),兼顾强度与韧性,杜绝钢丝脆断风险
    最小破断拉力系数≥0.39(满足 GB 8903-2018 强制要求),安全冗余充足,配套电梯安全系数≥12
    蠕变伸长率≤0.06%(额定载荷下运行 10⁴次),确保电梯平层精度≤±1.5mm

    三、典型性能表(1770MPa 镀锌磷化 + 电梯专用脂)

    公称直径(mm)参考重量(kg/100m)最小破断拉力(kN)适配电梯类型
    613.211.5杂物电梯、小型医用电梯
    829.025.8住宅乘客电梯(6 人以下)
    1045.539.0中型乘客电梯、轻型载货电梯
    1264.556.5商用轻型载货电梯、观光电梯

    四、电梯工况核心特性

    1. 高耐磨适配高频次运行
      西鲁式股外层粗钢丝结构 + 面接触压实工艺,与曳引轮槽的接触应力分布均匀,耐磨性能优异,适配住宅电梯每日高频次启停的使用场景,钢丝绳使用寿命比普通复合股型号延长 30%~50%。
    2. 高柔韧性适配小机房电梯
      绳体最小弯曲半径可低至8 倍绳径,配合紧凑的钢芯结构,安装布线时可灵活适配小机房电梯的狭小空间,无硬弯、卡阻风险,降低安装难度。
    3. 低噪音运行提升乘坐体验
      面接触结构消除了股内钢丝的微动摩擦噪音,搭配专用低噪音曳引脂,运行过程中摩擦噪音≤48dB(额定速度 1.0m/s),远低于国标噪音限值,提升乘客乘坐舒适度。
    4. 高安全冗余杜绝安全隐患
      最小破断拉力系数符合国标强制要求,在电梯 125% 超载试验、110% 超速试验中均能稳定运行,无打滑、断丝风险;抗旋转性能优异,避免因绳体扭转导致的轿厢偏摆。

    五、电梯专用选型与维保要点

    1. 选型匹配要求
      • 绳径与曳引轮直径比需满足 d/D ≤ 1/40(GB 7588-2020 强制要求),避免过度弯曲导致钢丝疲劳断丝
      • 槽型匹配:6~8mm 绳径适配半圆槽,10~12mm 绳径适配浅 U 型槽,提升曳引力,降低打滑概率
      • 严禁用通用 8×19S-IWRC 替代电梯专用型号,两者耐疲劳性能、抗旋转性能差异显著
    2. 维保关键事项
      • 润滑管理:仅可使用电梯专用曳引脂,禁止使用普通钢丝绳润滑脂(易打滑、腐蚀绳芯);脂层厚度保持 0.1~0.2mm,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(GB 8903-2018):① 单股断丝数≥2 根;② 绳径磨损≥5%;③ 钢丝绳出现锈蚀、变形、松股、跳丝
      • 更换周期:建议每 4 年强制更换(或运行里程达 35 万 km),即使外观无明显损伤也需更换,避免疲劳断裂风险

常见问题

阐述什么样的润滑剂可以防止钢丝绳损害?


一、光滑油具有良好的流动性和浸透能力,在钢丝绳进行光滑预处理时就能敏捷进入绳子内部以及绳芯,并能起到避免细菌在绳芯纤维内部繁殖的作用。

二、光滑油粘附在钢丝绳上不会轻易被擦掉,在规定的温度变化范围内光滑作用也不会受到影响。此外,具有粘附功能的光滑油还能防滑,这对电梯用钢丝绳附着摩擦力供给了协助。

三、有着较高的油膜强度,能在极重载荷下抵抗彼此接触的钢丝之间存在的极高压力,还能抗分解、蜕变。

四、光滑油油脂具有较高的内聚力,可以避免光滑油的滴落,没有运动时离心甩失,避免油脂糟蹋以及对其他设备的污染。

五、不含有会引起钢丝绳产生腐蚀、生锈的成分,防腐蚀、防锈蚀的作用更佳。

六、其自我修正的能力强,钢丝绳运用时不断产生曲折,会使其表面油膜不断揉捏扩张。这就需求柔软的并且有较高温润性的油膜来维护绳体免于开裂。
