    最小破断拉力系数≥0.40(满足 GB 8903-2018 强制要求),配套电梯安全系数≥14,满足 125% 超载工况的安全冗余需求
    蠕变伸长率≤0.05%(额定载荷下运行 10⁴次),确保中高层轻型电梯平层精度≤±1.0mm
    运行速度适配最大适配电梯运行速度 3.5m/s,满足别墅观光电梯、小户型住宅电梯的运输需求

    三、典型性能表(1770MPa 镀锌磷化 + 静音曳引脂)

    公称直径(mm)参考重量(kg/100m)最小破断拉力(kN)适配电梯类型
    82523.8别墅杂物电梯、小型医用电梯(载重 0.8t)

    四、轻型中高速电梯工况核心特性

    1. 轻量化低能耗,适配小机房电梯
      17 丝西鲁式股结构相比 19 丝型号重量减轻 10%~12%,可降低曳引机运行负载与能耗,同时绳体柔韧性更优,在别墅、小户型住宅的小机房内布线时,可灵活弯折,无硬弯、卡阻风险,缩短安装工期。
    2. 超低噪音运行,提升轻型电梯舒适度
      面接触压实工艺消除股内钢丝微动摩擦噪音,搭配 PU 芯的缓冲减振设计,电梯以 3.0m/s 运行时,轿厢内噪音≤40dB,达到别墅电梯静音标准,远超普通 8 股钢丝绳的噪音控制效果。
    3. 高抗旋转稳运行,适配中高层轻型工况
      9 股对称结构 + 交叉捻工艺,抗旋转性能优于传统 8 股电梯绳,电梯在满载 / 空载切换、高速加减速时,轿厢摆动幅度≤±2.5mm,无明显晃动,尤其适合别墅观光电梯的平稳观景需求。
    4. 耐疲劳长寿命,降低轻型电梯维保成本
      面接触钢丝结构配合电梯专用静音曳引脂,钢丝绳使用寿命比普通 8 股电梯绳延长 60%~70%;中高层轻型电梯换绳周期可延长至 7~8 年,减少高空换绳的人工成本。

    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 ≤ 1/45(中高速轻型电梯强化要求,高于 GB 7588-2020 标准的 1/40),避免绳体过度弯曲导致疲劳断丝
      • 槽型匹配:8~10mm 绳径适配深 U 型槽,14mm 绳径适配加宽弧形槽,提升曳引力,杜绝高速运行打滑风险
      • 严禁用通用 9×17S-PWRC 替代电梯专用型号,两者耐疲劳性能、抗旋转性能、降噪性能差异显著
    2. 维保关键事项
      • 润滑管理:仅可使用电梯专用静音曳引脂,禁止使用普通钢丝绳润滑脂(易高温流失、引发打滑);脂层厚度保持 0.18~0.22mm,补脂周期建议为 12 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≥3.8%;③ 钢丝绳出现锈蚀、变形、松股、跳丝
      • 更换周期:建议每 7~8 年强制更换(或运行里程达 75 万 km),中高层轻型电梯换绳需采用专业小型高空作业设备,避免绳体弯折损伤

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。
