沥青防腐作业线、黄夹克作业线、泡沫黄夹克防腐保温作业线以及其它各种管道作业线都离不开传动台,而每一个传动台都必不可少传动辊子。对于传动辊子的设计,各油田、各作业线又有各种不同的形式,如 U 形辊子、V形辊子、圆柱形辊子等等。其安装形式更是多种多样,如大直径的 U 形辊子和圆柱形辊子的安装必须配以立式圆柱形辊子做导正;V 形辊 Asphalt preservative line, yellow jacket line, foam yellow jacket anti-corrosion insulation line and a variety of other pipeline operations are inseparable from the transmission station, and each transmission are essential drive roller. For the transmission roller design, the oil fields, there are various lines of operation in different forms, such as U-shaped roller, V-shaped roller, cylindrical roller and so on. The installation form is more varied, such as large-diameter U-shaped roller and cylindrical roller installation must be equipped with vertical cylindrical roller for guidance; V-shaped roller
