閥門等離子堆焊機(jī)是解決閥門密封面耐磨、耐蝕、耐高溫問題的專業(yè)化設(shè)備。眾所周知，閥門內(nèi)漏的主要原因是密封面的損壞，造成密封面損壞的原因很多，主要有機(jī)械原因和化學(xué)原因，其中磨粒磨損、沖擊磨損、壓力磨損為機(jī)械原因，腐蝕和氣蝕磨損為化學(xué)原因。閥門密封面都要受到上述一種或兩種以上的復(fù)合磨損。尤其是**閥門，如高溫高壓電站閥、核工業(yè)閥門、長輸管線閥門，德陽等離子堆焊加工、井口閥、石油化工閥門等，其工況條件十分惡劣，有的工作壓力高達(dá)，有的工作溫度高達(dá)540℃以上，有的要求開啟10萬次密封面不損壞，有的閥門要求使用30年密封面不泄漏，這樣苛刻的要求，德陽等離子堆焊加工，不是普通材料和一般工藝所能解決的。因此，德陽等離子堆焊加工，一些工業(yè)發(fā)達(dá)國家在閥門密封面的堆焊材料、焊接工藝、焊接設(shè)備方面進(jìn)行了大量的試驗(yàn)研究，其中等離子堆焊技術(shù)**為成功。為此我們公司吸取國內(nèi)外同類產(chǎn)品的優(yōu)點(diǎn)，并結(jié)合本公司在多年在焊接領(lǐng)域?qū)嵤┊a(chǎn)品的經(jīng)驗(yàn)研發(fā)并設(shè)計(jì)了一款閥門-多功能等離子熔覆堆焊**設(shè)備（PTA），主要針對閥門制造業(yè)中的各種閥門自動(dòng)化堆焊，下面就介紹三偏心蝶閥堆焊的案例。上海等離子的發(fā)展方向是哪里？德陽等離子堆焊加工</p><div

等離子焊的常規(guī)原理 </p> <p> <br /> </p> <p> 主弧：控制焊道的熔池，電流越大熔池越大。 </p> <p> <br /> </p> <p> 微弧：起引燃主弧作用，焊接前必須先開微弧，主弧才能啟動(dòng)。 </p> <p> <br /> </p> <p> 離子氣：控制熔深，氣壓越大熔深越深。 </p> <p> <br /> </p> <p> 保護(hù)氣：控制焊道表面的顏色（防氧化，即用氬氣或氫氬混合氣隔絕熔池周邊的氧氣）。 </p> <p> <br /> </p> <p> 上升時(shí)間：時(shí)間范圍0.0-5.0 S 如設(shè)置0.5S，即主弧如是80A微弧是20A 起弧就是從20A開始0.5S內(nèi)慢慢升至80A 一個(gè)緩升的過程。 </p> <p> <br /> </p> <p> 下降時(shí)間：時(shí)間范圍0.0-5.0 S 如設(shè)置0.5S，即主弧如是80A微弧是20A 滅弧就是從80A開始0.5S內(nèi)慢慢降至80A 一個(gè)緩降的過程，達(dá)到平滑收弧的目的（注：自動(dòng)化停走必須在完全滅弧之后）。 </p> <p> <br /> </p> <p> 氣體保護(hù)時(shí)間：時(shí)間范圍0-20 S 如5S 即主弧熄火后繼續(xù)放氣5S 達(dá)到冷卻鎢極、防氧化的目的（因?yàn)殒u極在熄火后還處于紅的狀態(tài)，容易氧化，繼續(xù)放氣隔絕鎢極與氧氣的接觸，延長鎢極的使用壽命，氧化的鎢極不容易點(diǎn)火）。 </p> <p> <br /> </p> <p> 焊嘴與工件距離：理論是越近越好；越近銅嘴與工件之間越容易打火，我們建議小電流情況下控制1-3mm；銅嘴孔徑越大焊道越寬。

目前，常用的堆焊合金有鈷基合金、鎳基合金、鐵基合金和銅基合金等堆焊材料。其中鈷基合金具有良好的高溫性能，優(yōu)異的熱強(qiáng)性、耐蝕性及耐熱疲勞性能，比鐵基，鎳基合金的抗磨損、抗腐蝕性能好。所以在閥門研制和生產(chǎn)制造中，鈷基硬質(zhì)合金被廣泛應(yīng)用到各類閥門殼體和密封面的堆焊中。這些合金材料被制成電焊條、焊絲(含藥芯焊絲)、焊劑(含過渡合金型焊劑)和合金粉末等,采用手工電弧焊、氧-乙炔焰焊、鎢極氬弧焊、埋弧自動(dòng)焊和等離子弧焊等方法堆焊。選用閥門密封面堆焊材料一般根據(jù)閥門的使用溫度、工作壓力和介質(zhì)的腐蝕性,或閥門的類型、密封面結(jié)構(gòu)形式、密封比壓和許用比壓,或企業(yè)生產(chǎn)制造條件、設(shè)備加工能力和堆焊技術(shù)能力及用戶要求。

機(jī)械密封件本體材料的選擇因?yàn)槊芊猸h(huán)、球閥在腐蝕介質(zhì)中工作，要求有較好的耐晶間腐蝕性能和穩(wěn)定性。所以，根據(jù)其使用環(huán)境和技術(shù)要求，密封環(huán)、球閥本體材料選用了1Cr18Ni9Ti不銹鋼。等離子粉末堆焊材料的選擇欲獲得高質(zhì)量的金屬堆焊層，堆焊材料的選擇至關(guān)重要。有些堆焊實(shí)驗(yàn)證明：當(dāng)基體韌性不好時(shí)（如含C量過高、針狀馬氏體為主），雖然堆焊層的硬度可以提高，但往往容易產(chǎn)生微裂紋，使耐磨性變差。因此，片面地追求堆焊金屬的高硬度是不利的，也是不必要的。只有改善堆焊金屬的組.織狀態(tài)，使硬度與韌性得到恰當(dāng)?shù)呐浜?，才能夠有效地提高堆焊金屬的耐磨性。為了有效地防止堆焊金屬產(chǎn)生裂紋并獲得優(yōu)良的韌性和塑性，我們選用了S111硬質(zhì)合金焊絲。該焊絲是一種CoCrW合金焊絲。該堆焊層具有優(yōu)良的耐磨、耐溫和耐腐蝕性能，即使在650℃～700℃的高溫中亦能保持這些特點(diǎn)。德陽等離子堆焊加工</p><p
