alt="烏市大口徑波紋管費用" src="http://tyunfile.71360.com/UploadFile/xjhssl/637229977912373047/454447.jpg"></div><p> 波紋管耐壓力： </p> <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。波紋管的耐壓力實際上屬于波紋管的強度范疇。計算的關(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)力點的應(yīng)力不超過材料的屈服強度，波紋管所受的壓力就不會達到其耐壓力。同一波紋管在其它工作條件相同時，受外壓比受內(nèi)壓時的穩(wěn)定性要好，所以，受外壓作用時的比較大耐壓力比受內(nèi)壓時高。當(dāng)波紋管兩端固定，如果在其內(nèi)腔通入足夠大的壓力時，波紋管波峰處有可能爆破損壞。波紋管開始出現(xiàn)爆破時波紋管內(nèi)部的壓力值稱為爆破壓力。爆破壓力是表征波紋管比較大耐壓強度的參數(shù)。波紋管在整個工作過程中，其工作壓力遠(yuǎn)小于爆破壓力，否則波紋管將破裂損壞。當(dāng)波紋長度小于或等于外徑時，其計算結(jié)果和實際爆破壓力很接近；對細(xì)長型波紋管其實際爆破壓力要低很多。爆破壓力大約為允許工作壓力的3~10倍。

金屬波紋管設(shè)計的理論基礎(chǔ)是板殼理論、材料力學(xué)、計算數(shù)學(xué)等。波紋管設(shè)計的參數(shù)較多，由于波紋管在系統(tǒng)中的用途不同，其設(shè)計計算的重點也不一樣。例如，波紋管用于力平衡元件，要求波紋管在工作范圍內(nèi)其有效面積不變或變化很小，用于測量元件，要求波紋管的彈性特性是線性的；用于真空開關(guān)管作真空密封件，要求波紋管的真空密封性、軸向位移量和疲勞壽命；用于閥門作密封件，要求波紋管應(yīng)具有一定的耐壓力、耐腐蝕、耐溫度、工作位移和疲勞壽命。根據(jù)波紋管的結(jié)構(gòu)特點，可以把波紋管當(dāng)作圓環(huán)殼、扁錐殼或圓環(huán)板所組成。設(shè)計計算波紋管也就是設(shè)計計算圓外殼、扁錐殼或團環(huán)板。計算的參數(shù)為剛度、應(yīng)力、有效面積、失穩(wěn)、允許位移、耐壓力和使用壽命。
