PE管焊接机,63-160四环手动热熔机/PE热熔机焊接全过程(操作使用说明) 
热熔对接机中无论是手动型,还是液压型,加热板和铣刀是必须的,不同的是前者依靠人工操控,后者由液压系统提供动力,实现液压自动控制,尤其对于口径较大的管道,在铣、加热和冷却时都需要很大的压力,人力一般很难做到。整个对接过程大致可以分为:放、铣、热、冷几个步骤, 
  管材固定
把管材固定在机架上,中间留出5-8厘米的距离。
The carriage Jawws are clamped around the pipe.
  1.铣削
将铣刀放入机架,适当调整切削压力对管材端面进行切削。待形成连续切割后缓慢减小切削压力,并撤出铣刀,以保证管材端面光滑平整。
The pipe ends are faced flat & parallel to each other to give a good mating for fusion.
  2.管端加热
加热板待恒温后放入机架对管材端面进行加热,并根据管径及环境温度来调整加热时间及压力。
The heater is placed into machine, Both pipe ends are brought together against the heater.
  3.焊接
管端加热后迅速将加热板移开,然后立即将管材对接,并根据管径的不同进行对接压力调整。
The pipe soaks against the heater and begins to melt. Both ends are brought together and beg in to bond immediately.
  4.完成
当焊口温度降到与环境一致时,将管材自焊接机上移开。完全的接口强度可达到甚至超过本身的强度。
The pipe is held at pressure until cool leaving a joint stronger than the pipe.
