二、非金屬膨脹節(jié)非金屬柔性補償器：也稱非金屬膨脹節(jié)、非金屬織物補償器，可補償軸向、橫向、角向，具有無推力、簡化支座設(shè)計、耐腐蝕、耐高溫、消聲減振等特點，特別適用于熱風(fēng)管道及煙塵管道。特點：1、補償熱膨脹：可以補償多方向，比較優(yōu)于只能單式補償?shù)慕饘傺a償器。2、良好的耐高溫、耐腐蝕性：選用的氟塑料、有機硅材料具有較好的耐高溫和耐腐蝕性能。3、密封性能好：有比較完善的生產(chǎn)裝配系統(tǒng)，纖維補償器可保證無泄露。4、體輕、結(jié)構(gòu)簡單、安裝維修方便。5、補償安裝誤差：由于管道連接過程中，系統(tǒng)誤差再所難免，纖維補償器較好的補償了安裝誤差。6、消聲減振：纖維織物、保溫棉體本身具有吸聲、隔震動傳遞的功能，能有效的減少鍋爐、風(fēng)機等系統(tǒng)的噪聲和震動。7、無反推力：由于主體材料為纖維織物，無力的傳遞。用纖維補償器可簡化設(shè)計，避免使用大的支座，節(jié)省大量的材料和勞動力。8、價格低于金屬補償器、質(zhì)量優(yōu)于進口產(chǎn)品。氟塑料化工泵哪家好，上海原孚泵業(yè)值得信賴，歡迎有需求的朋友們聯(lián)系我司！</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="廣東化工泵品牌,泵" src="https://tyunfile.71360.com/UploadFile/shyfby/637444922442087550/7092855.png"></div><p> 一般情況下，選用波紋管的材料應(yīng)滿足下列條件：（1）高彈性極限、抗拉強度和疲勞強度，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，且能通過隨后的處理工藝（冷作硬化、熱處理等）獲得足夠的硬度和強度。（3）較好的耐腐蝕性能，滿足波紋管在不同環(huán)境下工作要求。（4）良好的焊接性能，滿足波紋管在制作過程中的焊接工藝要求。對于地溝敷設(shè)的熱力管網(wǎng)，當補償器所處管道地勢較低時，雨水或事故性污水會浸泡波紋管，應(yīng)考慮選用耐蝕性更強的材料，如鐵鎳合金、高鎳合金等。由于此類材料價格較高，在制造波紋管時，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)計由波紋管補償器的失效類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)。過低的疲勞壽命將會導(dǎo)致金屬波紋管穩(wěn)定性及耐蝕性能下降。酸堿泵哪家好，上海原孚泵業(yè)值得信賴。山西襯氟離心泵生產(chǎn)</p><p style="text-indent:25px">氟塑料化工泵哪家好，上海原孚泵業(yè)值得信賴，還等什么，快來call我司吧！廣東化工泵品牌</p>根據(jù)揚程識別離心泵汽蝕 <p> 這是一種簡單易行，且在業(yè)內(nèi)得到廣泛應(yīng)用的方法。當汽蝕發(fā)生時，離心泵的揚程會急劇下降。API610標準中，將離心泵揚程(對于多級泵而言是級揚程)下降3%，作為性能斷裂的標志，并依此判定離心泵的必需汽蝕余量NPSHr的數(shù)值。通常當離心泵特性曲線上揚程下跌3%時，我們認為這個點是其發(fā)生汽蝕的臨界點，但是在泵發(fā)生汽蝕的初始階段，離心泵揚程的變化并不是很明顯，而當揚程變化明顯時，汽蝕已經(jīng)發(fā)展到了一定程度，所以用揚程來判斷離心泵的汽蝕具有一定的滯后性。廣東化工泵品牌</p><p
