¥1,000.00
YK Dredger dredging rubber hoses are strictly manufactured in accordance with the industry standard HG/T 2490-2023, specially designed for high-intensity operation scenarios such as river dredging, port construction and waterway dredging. The product range includes floating type (for conveying only) and non-floating type (for both conveying and suction), with nominal inner diameters ranging from 100mm to 1300mm, suitable for transporting media like slurry, gravel and coral under the temperature condition of -20℃~40℃.
Featuring a highly wear-resistant synthetic rubber inner lining and a multi-layer steel wire/cord reinforced structure, its wear-resistant service life is increased by more than 60% compared with ordinary hoses. It boasts excellent pressure-bearing and explosion-proof performance, with zero hidden risks of sealing and leakage. The outer layer is UV-resistant and ozone aging-resistant, with strong flexibility to adapt to multi-angle operations. The flange joint design enables quick assembly and disassembly. Widely used in dredger supporting, urban drainage, mine tailings transportation and other fields, it provides stable and efficient conveying solutions for various dredging projects.
核心定义和应用场景
基本定义
A dredging rubber hose is a flexible tubular device with a wear-resistant rubber inner lining and a multi-layer reinforced framework, mainly used for conveying and sucking slurry, gravel and other media in dredging projects. It is compatible with working scenarios such as dredgers and drainage equipment, featuring high pressure resistance, wear resistance and easy assembly and disassembly.
主要用途
- 港口和航道疏浚、土地开垦、河道疏浚
- 矿山尾矿运输、市政污水处理项目
- 刚性管道之间的柔性连接，用于吸收振动和抵消位移
核心价值
确保疏浚系统持续运行，减轻船体震动和水流的影响，并延长管道系统的使用寿命。
结构组成（三层复合材料设计）
内层
耐磨橡胶（天然橡胶/丁腈橡胶/氯丁橡胶）或UPE衬里。它具有优异的耐磨性和抗冲击性，并能降低输送阻力。
加固层
多层聚酯纤维织物与螺旋钢丝/钢带相结合，可提供抗压强度、负压强度和抗拉强度，防止软管塌陷或爆裂。
外层
耐候抗老化橡胶。它能抵抗海水腐蚀、紫外线辐射和机械损伤。
连接结构
法兰式（国标/美标/日标）或卡箍式，可实现快速连接和拆卸。

选择和维护点
选择原则
- 根据颗粒大小选择内衬材料：小颗粒用普通橡胶；大颗粒用UPE或铠装橡胶。
- 根据工作压力选择加固层：高压工况下采用多层钢丝加固。
- 根据工作条件选择软管类型：浮动式软管适用于水应用；吸入式软管适用于吸入入口系统。
维护建议
- 避免阳光直射；长期存放请置于阴凉避光处。
- 定期检查内层橡胶的磨损情况和增强层的损坏情况；如果发现裂纹，应立即更换软管。
- 使用后清理软管内残留的介质，以防止介质凝固和堵塞。
- 避免过度弯曲或扭转软管，以保护增强层结构的完整性。
