免維護的桿端軸承

緊湊，堅固，耐腐蝕內部加(jia)壓(ya)儲液罐(guan)可(ke)與其(qi)他制造商單(dan)(dan)位互換可(ke)免維護的桿(gan)端(duan)軸承，承受純靜態(tai)載荷的管道(dao)系(xi)統通(tong)常支撐(cheng)在單(dan)(dan)作用垂(chui)直支架(jia)上，例(li)如吊桿(gan)和管夾(jia)，滑動(dong)(dong)基座或(huo)其(qi)他剛性(xing)類(lei)型(xing)的支撐(cheng)。如果管道(dao)溫(wen)度(du)變化(hua)，則這些垂(chui)直支架(jia)中的一些或(huo)全(quan)部可(ke)以(yi)是可(ke)變或(huo)恒定力類(lei)型(xing)的彈(dan)簧支架(jia)。通(tong)常不能(neng)由(you)承載管道(dao)自重(zhong)的同(tong)一系(xi)統提供管道(dao)的動(dong)(dong)態(tai)約(yue)束。動(dong)(dong)態(tai)加(jia)載可(ke)能(neng)有多種原因(yin)。諸(zhu)如由(you)于(yu)閥關閉(bi)引(yin)起的不穩定流動(dong)(dong)會(hui)產生動(dong)(dong)力，稱為水錘。在地(di)震中，管道(dao)系(xi)統也(ye)會(hui)承受動(dong)(dong)力。

在(zai)管(guan)(guan)道(dao)(dao)系統(tong)受(shou)到(dao)動(dong)(dong)(dong)力作用(yong)(yong)的(de)(de)地方，會(hui)(hui)發(fa)生(sheng)管(guan)(guan)道(dao)(dao)振(zhen)動(dong)(dong)(dong)。這可(ke)能會(hui)(hui)對管(guan)(guan)道(dao)(dao)，連接的(de)(de)設(she)備(bei)和工廠造成傷害。支(zhi)撐在(zai)單作用(yong)(yong)垂直約(yue)(yue)(yue)束(shu)和沒有(you)(you)側(ce)向(xiang)約(yue)(yue)(yue)束(shu)的(de)(de)彈簧上的(de)(de)管(guan)(guan)道(dao)(dao)系統(tong)將具有(you)(you)較低的(de)(de)固有(you)(you)振(zhen)動(dong)(dong)(dong)頻率(lv)，并且(qie)在(zai)受(shou)到(dao)振(zhen)動(dong)(dong)(dong)時會(hui)(hui)經歷較大的(de)(de)動(dong)(dong)(dong)態撓度；這通常是(shi)不可(ke)接受(shou)的(de)(de)。通過響應譜或時程分(fen)析(xi)進(jin)行的(de)(de)管(guan)(guan)道(dao)(dao)應力分(fen)析(xi)可(ke)用(yong)(yong)于(yu)顯(xian)示對動(dong)(dong)(dong)態約(yue)(yue)(yue)束(shu)的(de)(de)需(xu)求(qiu)。在(zai)承受(shou)動(dong)(dong)(dong)態載(zai)(zai)荷的(de)(de)管(guan)(guan)道(dao)(dao)系統(tong)中，可(ke)能有(you)(you)使用(yong)(yong)在(zai)兩(liang)個方向(xiang)上都起作用(yong)(yong)的(de)(de)剛性支(zhi)柱(zhu)，而不是(shi)僅(jin)使用(yong)(yong)向(xiang)下支(zhi)撐載(zai)(zai)荷的(de)(de)吊桿。剛性支(zhi)柱(zhu)還(huan)用(yong)(yong)于(yu)在(zai)需(xu)要(yao)時提供橫向(xiang)約(yue)(yue)(yue)束(shu)。在(zai)需(xu)要(yao)動(dong)(dong)(dong)態約(yue)(yue)(yue)束(shu)的(de)(de)地方使用(yong)(yong)緩沖劑，但(dan)是(shi)允許管(guan)(guan)子熱移動(dong)(dong)(dong)。
