波紋電力管廠家對比金屬波紋管與塑料波紋管的區別

  2021年11月10日，波紋電力管廠家對(dui)比金屬(shu)波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)與(yu)塑料波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)的區(qu)別(bie)。波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)是(shi)指用(yong)可折疊皺(zhou)紋(wen)(wen)片(pian)(pian)沿折疊 伸(shen)縮 方向連接成(cheng)的管(guan)(guan)(guan)(guan)狀彈(dan)性敏感元(yuan)件(jian)。波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)在(zai)儀器(qi)(qi)儀表中應用(yong)廣泛，主要用(yong)途是(shi)作為(wei)壓(ya)(ya)(ya)力(li)測(ce)(ce)量(liang)儀表的測(ce)(ce)量(liang)元(yuan)件(jian)，將壓(ya)(ya)(ya)力(li)轉換成(cheng)位(wei)移(yi)或(huo)力(li)。波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)管(guan)(guan)(guan)(guan)壁較薄，靈敏度較高，測(ce)(ce)量(liang)范圍為(wei)數十帕至(zhi)數十兆帕。它(ta)的開口端(duan)固(gu)定，密封(feng)端(duan)處于(yu)自由(you)(you)狀態(tai)，并利用(yong)輔助的螺旋(xuan)彈(dan)簧或(huo)簧片(pian)(pian)增加彈(dan)性。工作時(shi)在(zai)內部壓(ya)(ya)(ya)力(li)的作用(yong)下沿管(guan)(guan)(guan)(guan)子長度方向伸(shen)長，使活動(dong)端(duan)產(chan)生與(yu)壓(ya)(ya)(ya)力(li)成(cheng)一(yi)定關系(xi)的位(wei)移(yi)。活動(dong)端(duan)帶動(dong)指針即可直(zhi)接指示壓(ya)(ya)(ya)力(li)的大(da)小(xiao)。波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)常常與(yu) 位(wei)移(yi)傳感器(qi)(qi) 組合起來構成(cheng)輸(shu)出為(wei)電(dian)量(liang)的壓(ya)(ya)(ya)力(li)傳感器(qi)(qi)，有時(shi)也用(yong)作隔離元(yuan)件(jian)。由(you)(you)于(yu)波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)的伸(shen)展要求較大(da)的容積變化，因此它(ta)的響應速度低于(yu)波(bo)(bo)登管(guan)(guan)(guan)(guan)。波(bo)(bo)紋(wen)(wen)管(guan)(guan)(guan)(guan)適于(yu)測(ce)(ce)量(liang)低壓(ya)(ya)(ya)。
