與波紋賠償器鋼波紋涵管接觸的(de)保溫資料應不(bu)含氯(lv)。水(shui)(shui)壓(ya)實(shi)驗(yan)時,應對裝有波(bo)紋賠(pei)償器(qi)管路端部(bu)的(de)次固(gu)定管架進行加固(gu),使管路不(bu)發生(sheng)發火挪動或(huo)轉變。對用于氣(qi)體介質的(de)賠(pei)償器(qi)及其銜接管路,要注意充水(shui)(shui)時能否需求增設暫時支架。水(shui)(shui)壓(ya)實(shi)驗(yan)用水(shui)(shui)清(qing)洗液的(de)96氯(lv)離子含量不(bu)超越25PPM。水(shui)(shui)壓(ya)實(shi)驗(yan)完畢后,應盡(jin)快(kuai)排波(bo)殼中的(de)積(ji)水(shui)(shui),并靈敏將波(bo)殼內外表吹(chui)干。
鋼波紋涵管如何安裝才能增加使用壽命?
對(dui)帶內套(tao)筒的(de)(de)賠(pei)償器(qi)應(ying)注意使內套(tao)筒子的(de)(de)偏(pian)向(xiang)與(yu)介質流(liu)動偏(pian)向(xiang)一致,搭(da)鈕(niu)型賠(pei)償器(qi)的(de)(de)搭(da)鈕(niu)轉(zhuan)變平(ping)面應(ying)與(yu)位移轉(zhuan)變平(ping)面一致。管系裝(zhuang)置終了后,應(ying)盡快撤除(chu)波紋賠(pei)償器(qi)上用作裝(zhuang)置運(yun)輸(shu)的(de)(de)黃色(se)輔佐定(ding)位構件(jian)及緊固件(jian),并按設計要求(qiu)將限位安(an)裝(zhuang)調(diao)到規則地位,使管系在情(qing)況(kuang)條件(jian)下(xia)有(you)充沛的(de)(de)賠(pei)償才能。
金(jin)(jin)(jin)(jin)屬(shu)(shu)波紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)涵(han)(han)是將薄金(jin)(jin)(jin)(jin)屬(shu)(shu)板板面(mian)壓成波紋(wen)(wen)(wen)后,卷制成管(guan)(guan)(guan)(guan)(guan)節(jie),可以增加管(guan)(guan)(guan)(guan)(guan)節(jie)的(de)(de)剛度(du)和對管(guan)(guan)(guan)(guan)(guan)軸壓力的(de)(de)抵(di)擋強(qiang)度(du);出廠(chang)前采用熱浸鍍鋅(xin)工(gong)藝和施(shi)工(gong)現場噴涂瀝青,雙(shuang)層(ceng)防(fang)腐處理保證(zheng)(zheng)了(le)使用壽命;用此種管(guan)(guan)(guan)(guan)(guan)節(jie)修建(jian)的(de)(de)涵(han)(han)洞(dong)(dong)被稱為波紋(wen)(wen)(wen)金(jin)(jin)(jin)(jin)屬(shu)(shu)管(guan)(guan)(guan)(guan)(guan)涵(han)(han)。實(shi)踐證(zheng)(zheng)實(shi),用金(jin)(jin)(jin)(jin)屬(shu)(shu)波紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)涵(han)(han)代替金(jin)(jin)(jin)(jin)屬(shu)(shu)筋混凝土(tu)進(jin)行(xing)涵(han)(han)洞(dong)(dong)施(shi)工(gong),不管(guan)(guan)(guan)(guan)(guan)從施(shi)工(gong)周期、施(shi)工(gong)造價、環保意義(yi)等(deng)方(fang)面(mian)都(dou)有其不可相比的(de)(de)優勝性,且用金(jin)(jin)(jin)(jin)屬(shu)(shu)波紋(wen)(wen)(wen)管(guan)(guan)(guan)(guan)(guan)涵(han)(han)進(jin)行(xing)涵(han)(han)洞(dong)(dong)施(shi)工(gong),可大大進(jin)步道路行(xing)車的(de)(de)恬靜度(du)與安全性,避免(mian)道路中(zhong)涵(han)(han)洞(dong)(dong)的(de)(de)“錯臺跳車”現形(xing),有利(li)于解決西北地區嚴寒霜凍對砼(tong)管(guan)(guan)(guan)(guan)(guan)涵(han)(han)結構的(de)(de)破壞題(ti)目。
波紋(wen)管(guan)(guan)設計計算的參(can)數為剛度(du)(du)(du)、應力(li)、有(you)效(xiao)面積(ji)、失(shi)穩、答應位(wei)移(yi)、耐壓力(li)和使用(yong)壽命。波紋(wen)管(guan)(guan)的剛度(du)(du)(du)計算,波紋(wen)管(guan)(guan)的剛度(du)(du)(du)按照載荷及位(wei)移(yi)性(xing)質不同,分為軸向剛度(du)(du)(du)、彎曲(qu)剛度(du)(du)(du)、扭轉剛度(du)(du)(du)等(deng)。目前(qian)在波紋(wen)管(guan)(guan)的應用(yong)中,絕大多數的受力(li)情況是(shi)軸向載荷,位(wei)移(yi)方式(shi)為線位(wei)移(yi)。
根(gen)據波紋(wen)管(guan)的結構特(te)點,可以把波紋(wen)管(guan)當(dang)作圓環(huan)殼(ke)(ke)、扁錐殼(ke)(ke)或圓環(huan)板所組成。設計(ji)(ji)(ji)計(ji)(ji)(ji)算(suan)波紋(wen)管(guan)也就是設計(ji)(ji)(ji)計(ji)(ji)(ji)算(suan)圓外殼(ke)(ke)、扁錐殼(ke)(ke)或團環(huan)板。
鋼波紋涵管設計(ji)(ji)(ji)(ji)的理論基礎是(shi)(shi)板殼理論、材料(liao)力學(xue)(xue)、計(ji)(ji)(ji)(ji)算(suan)數(shu)學(xue)(xue)等(deng)。波紋(wen)(wen)管(guan)(guan)設計(ji)(ji)(ji)(ji)的參數(shu)較多,因為(wei)波紋(wen)(wen)管(guan)(guan)在系統中的用(yong)(yong)途不同(tong),其設計(ji)(ji)(ji)(ji)計(ji)(ji)(ji)(ji)算(suan)的重點也不一樣。例如,波紋(wen)(wen)管(guan)(guan)用(yong)(yong)于(yu)力平衡元件,要(yao)(yao)求波紋(wen)(wen)管(guan)(guan)在工(gong)作范圍內(nei)其有效面積不變或變化(hua)很(hen)小,用(yong)(yong)于(yu)丈(zhang)量(liang)元件,要(yao)(yao)求波紋(wen)(wen)管(guan)(guan)的彈(dan)性(xing)特性(xing)是(shi)(shi)線性(xing)的;用(yong)(yong)于(yu)真(zhen)(zhen)空開關管(guan)(guan)作真(zhen)(zhen)空密(mi)封件,要(yao)(yao)求波紋(wen)(wen)管(guan)(guan)的真(zhen)(zhen)空密(mi)封性(xing)、軸向(xiang)位移量(liang)和(he)疲憊壽命;用(yong)(yong)于(yu)閥門作密(mi)封件,要(yao)(yao)求波紋(wen)(wen)管(guan)(guan)應具有一定的耐(nai)壓力、耐(nai)侵蝕、耐(nai)溫度、工(gong)作位移和(he)疲憊壽命。
嚴禁用(yong)(yong)波(bo)(bo)紋賠償器(qi)變(bian)形的(de)(de)辦法來調整管(guan)(guan)道的(de)(de)裝置超(chao)差,以免影響賠償器(qi)的(de)(de)正常功用(yong)(yong)、降(jiang)低運用(yong)(yong)壽命及添(tian)加(jia)管(guan)(guan)系、設備(bei)、支承構件的(de)(de)載荷(he)。裝置進程(cheng)中,不允許焊渣飛濺到(dao)波(bo)(bo)殼(ke)(ke)外(wai)表,不允許波(bo)(bo)殼(ke)(ke)遭到(dao)其它機械毀傷(shang)。
波紋(wen)賠償(chang)(chang)器在裝置(zhi)前應先(xian)反省其型號、規(gui)格及管(guan)道裝備狀況,必須契合(he)設計要求(qiu)。波紋(wen)賠償(chang)(chang)器一切(qie)運(yun)動元件不得被外(wai)部構件卡死或限(xian)制其運(yun)動局限(xian),應包管(guan)各(ge)運(yun)動部位的(de)正常舉措。需(xu)求(qiu)進行“冷緊(jin)”的(de)賠償(chang)(chang)器,預變形(xing)所用的(de)輔佐構件應在管(guan)路裝置(zhi)終了后方可撤除。
