在施工等径压缩PE管内衬法修复旧管道时所使用的主要设备。
The main equipment used in the construction of isometric compression PE pipe lining method for the repair of old pipelines.
1 缩径机Reducing machine
用于暂时缩小HDPE管的直径。设计的缩径机由变频调速电机驱动的多级滚压轮构成，靠滚轮滚压缩径。本设计具有能耗低、无级变速、速度自动耦合、操作简单方便、运行可靠等特点。HDPE管通过缩径机后，直径可缩小10%左右。
Used to temporarily reduce the diameter of the HDPE tube.The designed reducing machine is composed of a multi-stage roller driven by a variable frequency speed regulating motor, which rolls the compression diameter by the roller.This design has the characteristics of low energy consumption, continuously variable speed, automatic speed coupling, simple and convenient operation, reliable operation and so on.The diameter of HDPE tube can be reduced by about 10% after passing through the reducing machine.
2 牵引装置Winch
设计的牵引装置由绞车、导向滑轮、钢丝绳和牵引头等组成。绞车为柴油机驱动，能自动显示和记录牵引力、牵引速度和长度，最大可提供400千牛的牵引力。
The designed traction device is composed of winch, guide pulley, wire rope and traction head.Driven by diesel engines, the winch can automatically display and record traction force, traction speed and length, providing up to 400 KN of traction force.
3 热熔焊机Butt fusion welding machine
采用热熔焊技术连接HDPE管。为了形成连续长度的HDPE管，需要仔细地进行熔融对接，并对焊缝进行试压检查，外部焊道应光滑无裂缝。实验表明，熔融焊接处的强度高于管体本身的强度。
The HDPE tube is connected by hot fusion welding technology.In order to form a continuous length of HDPE tube, it is necessary to carefully melt the butt and test the weld. The external weld pass should be smooth and free of cracks.The experiment shows that the strength of the molten weld is higher than that of the tube itself.
4 复合法兰高温压制装置Compound flange high temperature pressing device
该装置由加热系统、液压系统和固定系统组成。可将聚乙烯衬管加热到一定温度后压紧在主管法兰端面上，构成紧密结合的复合法兰，在相邻两管段之间实现有效连接。
The device consists of heating system, hydraulic system and fixing system.The polyethylene liner can be heated to a certain temperature and then compressed on the end face of the main flange, forming a compound flange with a tight connection, and achieving effective connection between the adjacent two pipe segments.
5 管内自动摄像探测系统Internal automatic camera detection system
该系统可在管内跨越障碍物爬行3公里以上，并通过遥控系统对管内的状况进行三维摄像，可准确地探测出管内结垢、锈层及接口、铸馏等情况，这对铸铁管和水泥管的修复尤为重要。
The system can climb over obstacles in the tube for more than 3 kilometers, and conduct three-dimensional photography of the condition of the tube through the remote control system, which can accurately detect the scaling, rust layer, interface, casting distillation, etc., which is particularly important for the repair of cast iron pipe and cement pipe.
6 管线物理清洗设备Pipe physical cleaning equipment
从美国进口的高压水射流清洗设备及长输管线PIG物理清洗除馏系统，可有效地清除管内污垢、锈层、铸馏及焊馏，为穿插成功提供保证。
The high-pressure water jet cleaning equipment and the PIG physical cleaning dedistilling system of the long distance pipeline can effectively remove the dirt, rust layer, casting distillation and welding distillation inside the pipe, providing assurance for the success of interpenetration.
