摘要： 为了解决自动清洗钢丝螺旋线的流体动力自转力矩弱和磨损问题以及塑料扭带的不耐高温问题，提出以塑料包覆的大截面钢丝螺旋线来解决耐热、耐磨问题，并且以旋流管口轴承-动力轮来强化螺旋线自转动力矩的技术方案。试验研究表明，这种塑包钢丝螺旋线能够在较低流速下自动清洗，适用面较广，并且管内污垢的自动清洗能力强，对流传热强化的幅度达到52.6%，比钢丝螺旋线高60％；设备阻力不大，结构简单，成本低廉，具有优势。

Abstract: To solve weakness of self-rotating driving force, deficiency on capacity of resisting high temperature of plastic twisted strip, as well as abrasion,a scheme, which settles the heat-resistant and abrasion-resistant problems byplastic coat and intensifies the capacity of transferring self-rotating driving force by installing driving wheel at the tube inlets, is proposed. Results indicate that such spiral-insert can achieve auto-cleaning at low speed and can be widely utilized. In addition, its cleaning capacity is great. The enhancement of convective heat transfer is as great as 52.6%, which is 60% higher than that of steel spiral-insert. This equipment has advantages in lower resistance, lower cost and simpler structure.
Key words: steel spiral with plastic coat    enhancement of force moment    automatic clean    heat transfer enhancement    flowing resistance
