PE管焊接機(jī)，63-160四環(huán)手動(dòng)熱熔機(jī)/PE熱熔機(jī)焊接全過(guò)程(操作使用說(shuō)明) 

熱熔對(duì)接機(jī)中無(wú)論是手動(dòng)型，還是液壓型，加熱板和銑刀是必須的，不同的是前者依靠人工操控，后者由液壓系統(tǒng)提供動(dòng)力，實(shí)現(xiàn)液壓自動(dòng)控制，尤其對(duì)于口徑較大的管道，在銑、加熱和冷卻時(shí)都需要很大的壓力，人力一般很難做到。整個(gè)對(duì)接過(guò)程大致可以分為：放、銑、熱、冷幾個(gè)步驟， 

  管材固定
把管材固定在機(jī)架上，中間留出5-8厘米的距離。
The carriage Jawws are clamped around the pipe.

  1.銑削
將銑刀放入機(jī)架，適當(dāng)調(diào)整切削壓力對(duì)管材端面進(jìn)行切削。待形成連續(xù)切割后緩慢減小切削壓力，并撤出銑刀，以保證管材端面光滑平整。
The pipe ends are faced flat & parallel to each other to give a good mating for fusion.

  2.管端加熱
加熱板待恒溫后放入機(jī)架對(duì)管材端面進(jìn)行加熱，并根據(jù)管徑及環(huán)境溫度來(lái)調(diào)整加熱時(shí)間及壓力。
The heater is placed into machine， Both pipe ends are brought together against the heater.

  3.焊接
管端加熱后迅速將加熱板移開(kāi)，然后立即將管材對(duì)接，并根據(jù)管徑的不同進(jìn)行對(duì)接壓力調(diào)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
當(dāng)焊口溫度降到與環(huán)境一致時(shí)，將管材自焊接機(jī)上移開(kāi)。完全的接口強(qiáng)度可達(dá)到甚至超過(guò)本身的強(qiáng)度。
The pipe is held at pressure until cool leaving a joint stronger than the pipe.
