波紋管在儀器儀表中應(yīng)用大面積，主要用途是作為壓力測量儀表的測量元件，將壓力轉(zhuǎn)換成位移或力。波紋管管壁較薄，靈敏度較高，測量范圍為數(shù)十帕至數(shù)十兆帕。另外，波紋管也可以用作密封隔離元件，將兩種介質(zhì)分隔開來或防止有害流體進(jìn)入設(shè)備的測量部分。它還可以用作補(bǔ)償元件，利用其體積的可變性補(bǔ)償儀器的溫度誤差，遂寧聚乙烯波紋管供應(yīng)商。有時也用作為兩個零件的彈性聯(lián)接接頭等。波紋管按構(gòu)成材料可分為金屬波紋管，遂寧聚乙烯波紋管供應(yīng)商、非金屬波紋管兩種；按結(jié)構(gòu)可分為單層和多層。單層波紋管應(yīng)用較多。多層波紋管強(qiáng)度高，耐久性好，遂寧聚乙烯波紋管供應(yīng)商，應(yīng)力小，用在重要的測量中。波紋管的材料一般為青銅、黃銅、不銹鋼、蒙乃爾合金和因康鎳爾合金等。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="遂寧聚乙烯波紋管供應(yīng)商"

波紋管位移與零位偏移之間的關(guān)系，無論拉伸還是壓縮位移，在波紋管位移的起始階段，它的殘余變形量都很小，一般都小于波紋管標(biāo)準(zhǔn)中規(guī)定的允許零位偏移值。但是，當(dāng)拉伸（或壓縮）位移量逐漸增大到超過一定的位移值后，會引起零位偏移值的突然增大，這表示波紋管產(chǎn)生比較大的殘余變形，在這之后．如果再增大一點(diǎn)位移量，殘余變形將明顯增加。所以波紋管一般不應(yīng)超過這個位移量，不然將會嚴(yán)重的降低其精度、穩(wěn)定性和可靠性以及使用壽命。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="遂寧聚乙烯波紋管供應(yīng)商" src="https://tyunfile.71360.com/UploadFile/sccsjjc/637233344104472656/31666.jpg"></div><p> 耐壓力是波紋管性能的一個重要參數(shù)。波紋管在常溫時，波形上不發(fā)生塑性變形所能承受的比較大靜壓力，即為波紋管的比較大耐壓力在一般情況下，波紋管是在一定的壓力（內(nèi)壓或外壓）下工作的，所以它在整個工作過程中必須承受這個壓力而不產(chǎn)生塑性變形。波紋管的耐壓力實(shí)際上屬于波紋管的強(qiáng)度范疇。計(jì)算的關(guān)鍵是應(yīng)力分析，也就是分析波紋管管壁上的應(yīng)力只要波紋管管壁上比較大應(yīng)力點(diǎn)的應(yīng)力不超過材料的屈服強(qiáng)度，波紋管所受的壓力就不會達(dá)到其耐壓力。
