不銹鋼焊管近些年來(lái)，不銹鋼焊管行業(yè)的發(fā)展形勢(shì)相對(duì)較好，不管在規(guī)模、質(zhì)量、生產(chǎn)技術(shù)等方面都有了很大的進(jìn)步，特別是它的需求領(lǐng)域也在逐步擴(kuò)大。隨著不銹鋼焊管工藝的日漸成熟，業(yè)內(nèi)不禁有這樣的想法，不銹鋼焊管能否取代換熱器管發(fā)揮同樣的作用呢？下面，火炬為大家分析一下不銹鋼焊管取代換熱器管的可行性。其次，由于換熱器管構(gòu)成了換熱器的傳熱面，所以換熱器管的尺寸對(duì)傳熱有很大影響。采用小直徑的換熱器管時(shí)，存在制造麻煩，管子易結(jié)垢不易清洗的問(wèn)題，但是在GB/151-1999里管程壓力6.4MPa時(shí)，選擇與之匹配的不銹鋼焊管作為換熱器管，則可以避免以上問(wèn)題，因?yàn)椴讳P鋼焊管既具有良好的耐腐蝕性又具備光滑的表面，同時(shí)生產(chǎn)工藝成熟，所以不銹鋼焊管作為換熱器管是很有可能性的。
下面就以（下往上）一級(jí)級(jí)拆出為例：關(guān)閉進(jìn)出口閥門(mén)，排盡泵體內(nèi)的水，做好每一級(jí)拆卸標(biāo)記，。用拉碼拉出泵體上的聯(lián)軸器，拆出蓋扳螺母，取出軸承蓋扳，拆出軸承、軸封或填料盤(pán)根，拆卸磁環(huán)機(jī)械軸封時(shí)嚴(yán)禁硬撬硬打。拆出泵體出口與管網(wǎng)連接的螺絲，擰出泵體與底座固定螺栓。用麻繩捆扎在泵體2/5處，吊起水泵移離機(jī)座慢慢下放，往下放水泵時(shí)切記不要碰彎泵軸，將水泵平放在地面木板上。擰出泵軸尾螺母，拆出軸套，然后拆出葉輪，（拆卸過(guò)程中嚴(yán)禁直接鐵錘用力敲打軸套、葉輪），后取出外殼。
一體式空壓系統(tǒng)的儲(chǔ)氣單元主要有1組壓力緩沖罐6L容量，減少空壓機(jī)出氣后壓力波動(dòng)，提高用氣體穩(wěn)定；潔凈氣儲(chǔ)氣罐24L容量，保障臨時(shí)大氣量用氣。而且全部采用鋁合金擠壓成型工藝；不需要通過(guò)壓力容器的檢測(cè)報(bào)告。都經(jīng)過(guò)陽(yáng)極氧化和處理，延長(zhǎng)使用壽命，減少氣體二次污染的可能。由此可見(jiàn)，一體式空壓系統(tǒng)的經(jīng)濟(jì)實(shí)用性是無(wú)其他設(shè)備可比的，一臺(tái)設(shè)備就是一個(gè)空壓系統(tǒng)，換句話說(shuō)：一臺(tái)設(shè)備的價(jià)格就能擁有一整個(gè)空壓系統(tǒng)，是所有中小企業(yè)單位完整的壓縮空氣系統(tǒng)解決方案。
去處堵塞物，重新調(diào)整閥門(mén)開(kāi)度。穩(wěn)壓。更換葉輪。功率過(guò)大?？赡墚a(chǎn)生的原因：超過(guò)額定流量使用。吸程過(guò)高。更換軸承。相應(yīng)的排除方法：調(diào)整流量，關(guān)小出口閥門(mén)。降低安裝面。更換軸承。雜音振動(dòng)?？赡墚a(chǎn)生的原因：管路支撐不穩(wěn)。液體混有氣體。產(chǎn)生氣蝕。軸承損壞。電機(jī)超載發(fā)熱運(yùn)行。相應(yīng)的排除方法：穩(wěn)固管路。提高吸入壓力，排氣。降低真空度。調(diào)整按5。總結(jié)綜上所述可見(jiàn)四個(gè)鋼號(hào)有著較大的差別。根據(jù)使用要求必須選擇相適應(yīng)的標(biāo)準(zhǔn)，即對(duì)條鋼適用GB699，一般鋼管適用GB8163，輸送流體用一般無(wú)縫鋼管適用GB8163，低中壓鍋爐用無(wú)縫鋼管適用GB387，高壓鍋爐鋼管適用GB531，鍋爐受壓元件鋼板適用GB713，壓力容器及其附件適用GB6654。決不能用GB387的鋼管，更不能用GB8163的鋼管來(lái)替代GB531的鋼管。而更為重要的是在設(shè)計(jì)及訂貨時(shí)就要作出準(zhǔn)確的選擇。
