一般情況下，選用波紋管的材料應(yīng)滿(mǎn)足下列條件：（1）高彈性極限、抗拉強(qiáng)度和疲勞強(qiáng)度，保證波紋管正常工作。（2）良好的塑性，便于波紋管的加工成形，且能通過(guò)隨后的處理工藝（冷作硬化、熱處理等）獲得足夠的硬度和強(qiáng)度。（3）較好的耐腐蝕性能，滿(mǎn)足波紋管在不同環(huán)境下工作要求。（4）良好的焊接性能，滿(mǎn)足波紋管在制作過(guò)程中的焊接工藝要求。對(duì)于地溝敷設(shè)的熱力管網(wǎng)，當(dāng)補(bǔ)償器所處管道地勢(shì)較低時(shí)，雨水或事故性污水會(huì)浸泡波紋管，應(yīng)考慮選用耐蝕性更強(qiáng)的材料，如鐵鎳合金、高鎳合金等。由于此類(lèi)材料價(jià)格較高，在制造波紋管時(shí)，可以考慮*在與腐蝕性介質(zhì)接觸的表面增加一層耐蝕合金。疲勞壽命設(shè)計(jì)由波紋管補(bǔ)償器的失效類(lèi)型及原因分析可以看出，波紋管的平面穩(wěn)定性、周向穩(wěn)定性及耐腐蝕性能均與其位移量即疲勞壽命相關(guān)。過(guò)低的疲勞壽命將會(huì)導(dǎo)致金屬波紋管穩(wěn)定性及耐蝕性能下降。湖南四氟泵零售氟塑料化工泵哪家好，上海原孚泵業(yè)值得信賴(lài)，有需求的不要錯(cuò)過(guò)哦！</p><div

氨水又稱(chēng)阿摩尼亞水，主要成分為NH3·H2O，是氨的水溶液，無(wú)色透明且具有刺激性氣味。氨氣熔點(diǎn)-77℃，沸點(diǎn)36℃，密度3。氨氣易溶于水、乙醇。易揮發(fā)，具有部分堿的通性，氨水由氨氣通入水中制得。氨氣有毒，對(duì)眼、鼻、皮膚有刺激性和腐蝕性，能使人窒息，空氣中更高容許濃度30mg/m3。氨水有一定的腐蝕作用，碳化氨水的腐蝕性更加嚴(yán)重。對(duì)銅的腐蝕比較強(qiáng)，鋼鐵比較差，對(duì)水泥腐蝕不大。氨水泵操作與作用：1.檢查電動(dòng)機(jī)動(dòng)轉(zhuǎn)的方向，是否與泵的旋轉(zhuǎn)標(biāo)記一致。2.泵啟動(dòng)前檢查托架油室內(nèi)油位是否在規(guī)定范圍內(nèi)。3.開(kāi)啟進(jìn)口閥門(mén)，往水泵內(nèi)注足液體(引液)。4.關(guān)閉出口閥門(mén)。5.上述步聚完成后，啟動(dòng)電機(jī)慢慢打開(kāi)電機(jī)閥門(mén)，這時(shí)壓力表的位置將隨出水的大小和變化，當(dāng)壓力表指針指到需要的位置時(shí)，停止對(duì)閥門(mén)的調(diào)整。6.當(dāng)需要停車(chē)時(shí)，首先關(guān)閉出水閥門(mén)，切斷電源，再關(guān)閉進(jìn)口閥門(mén)。

防腐泵油封的正確安裝方法油封安裝前，軸或腔體一定不要受到“損傷”，否則會(huì)導(dǎo)致油封泄漏。中途搬運(yùn)一定要使用好用的油封搬運(yùn)夾具，這樣才能夠避免加工后的軸或者腔體產(chǎn)生碰撞。油封組裝前的準(zhǔn)備工作1.將油封從倉(cāng)庫(kù)中取出時(shí)，要查看油封表面以及唇口部位是否有灰塵及沙塵等雜質(zhì)，避免這些物質(zhì)在軸運(yùn)動(dòng)過(guò)程中損傷唇口和軸部，引起泄漏。2.對(duì)于像TC、TA、TB、TF這類(lèi)有兩個(gè)以上唇口的油封，請(qǐng)?jiān)诖娇诓刻畛錆?rùn)滑脂，對(duì)于像SC、VC、VB這類(lèi)單唇口油封也要在唇端涂抹潤(rùn)滑油脂。3.確認(rèn)軸、腔體表面無(wú)附著的防銹油或灰塵等異物，如有請(qǐng)清洗干凈。4.確認(rèn)軸腔體、倒角等表面無(wú)毛邊，避免安裝時(shí)這些毛邊會(huì)損傷唇口部位。5.向腔體內(nèi)組裝，要注意油封的安裝方向是將密封唇部朝向密封介質(zhì)一側(cè)。6.在安裝油封時(shí)，請(qǐng)使用好用夾具，以避免油封產(chǎn)生傾斜。另外，在安裝時(shí)經(jīng)常會(huì)發(fā)生以下幾種操作不當(dāng)案例，一定要注意避免。酸堿泵哪家好，上海原孚泵業(yè)值得信賴(lài)，詳細(xì)可訪(fǎng)問(wèn)我司官網(wǎng)查看！</p><div

二、水泵軸向力平衡方法平衡水泵轉(zhuǎn)子軸向力的方法多種多樣，例如在泵外部設(shè)置推力軸承、于水泵腔體上開(kāi)設(shè)平衡孔或平衡管以降低泵壓、葉輪設(shè)計(jì)時(shí)采用背葉片、雙葉輪、葉輪對(duì)稱(chēng)分布等形式，以及使用平衡盤(pán)、平衡鼓結(jié)構(gòu)等。其中，多利用平衡盤(pán)和平衡鼓結(jié)構(gòu)對(duì)轉(zhuǎn)子軸向力進(jìn)行平衡。平衡盤(pán)被廣泛應(yīng)用在多級(jí)泵的軸向力平衡上，位于泵末級(jí)葉輪之后。平衡裝置存在徑向和軸向兩個(gè)間隙，由末級(jí)流出的帶壓液體，經(jīng)徑向間隙流入平衡盤(pán)前的空腔中，使之形成高壓力狀態(tài)。于平衡盤(pán)后側(cè)的空腔上開(kāi)設(shè)平衡管，并與水泵入口相連通，使該處空腔內(nèi)壓力與泵入口處壓力基本一致。由于平衡盤(pán)前后兩空腔內(nèi)壓力不等，構(gòu)成壓力差，產(chǎn)生與軸向力反向的平衡力，達(dá)到平衡效果。采用平衡盤(pán)結(jié)構(gòu)平衡水泵轉(zhuǎn)子軸向力時(shí)，由于軸向力不斷變化，平衡力也隨之改變，因而，其工作過(guò)程是動(dòng)平衡過(guò)程。平衡盤(pán)依靠轉(zhuǎn)子竄動(dòng)自動(dòng)調(diào)節(jié)其可變間隙大小，從而調(diào)節(jié)平衡力大小，能夠充分平衡轉(zhuǎn)子軸向力，無(wú)需依靠外部推力軸承輔助，因而平衡結(jié)構(gòu)可省略外部推力軸承。黑龍江襯氟泵制造</p><p
