说明:①塑料管的管口应光滑,以免损伤电线的覆盖层。②管口内侧,应倒角至管厚剩下大约1/3。③偶联接头的内表面和管外的连接面要用干燥的布揩干净(特别是把油分全部揩掉),再在连接面上涂一层薄薄的速效胶粘剂,且不得漏涂,然后把管子插入接头中,如有可能的话,把管子转动约90°,按原样压紧,连接完成。④使用直通偶联接头时,用迟效性胶粘剂比较好。
Note: 1 The nozzle of the plastic tube should be smooth so as not to damage the covering layer of the electric wire. 2 The inside of the nozzle should be chamfered to approximately 1/3 of the tube thickness. 3 The inner surface of the coupling joint and the connection surface outside the pipe should be cleaned with a dry cloth (especially to remove all the oil), then apply a thin layer of quick-acting adhesive on the connection surface, and do not miss the coating. Insert the tube into the joint and, if possible, rotate the tube about 90°. Press it as it is and connect it. 4 When using a straight-through coupling, use a late-lasting adhesive.
