免維護的桿端軸承

緊湊，堅固，耐腐蝕(shi)內部(bu)加壓儲液(ye)罐可(ke)與其他制(zhi)造商(shang)單(dan)位互換可(ke)免(mian)維護的桿(gan)端軸(zhou)承，承受純靜態(tai)(tai)載荷的管(guan)道系統(tong)通常(chang)支(zhi)撐(cheng)在(zai)單(dan)作(zuo)用垂(chui)直(zhi)支(zhi)架上，例如吊桿(gan)和管(guan)夾，滑動(dong)基座(zuo)或(huo)其他剛(gang)性類(lei)型(xing)的支(zhi)撐(cheng)。如果管(guan)道溫度變化，則(ze)這些垂(chui)直(zhi)支(zhi)架中的一些或(huo)全(quan)部(bu)可(ke)以是可(ke)變或(huo)恒定(ding)力(li)類(lei)型(xing)的彈(dan)簧支(zhi)架。通常(chang)不(bu)能由(you)承載管(guan)道自重的同一系統(tong)提供管(guan)道的動(dong)態(tai)(tai)約束(shu)。動(dong)態(tai)(tai)加載可(ke)能有多種原因。諸如由(you)于閥關(guan)閉引(yin)起的不(bu)穩定(ding)流動(dong)會產(chan)生(sheng)動(dong)力(li)，稱為(wei)水錘。在(zai)地震中，管(guan)道系統(tong)也會承受動(dong)力(li)。

在(zai)管(guan)(guan)道(dao)系統受(shou)(shou)到動(dong)(dong)(dong)(dong)力作(zuo)用(yong)的(de)(de)地(di)方(fang)，會(hui)發(fa)生管(guan)(guan)道(dao)振動(dong)(dong)(dong)(dong)。這(zhe)可(ke)能(neng)(neng)會(hui)對(dui)管(guan)(guan)道(dao)，連(lian)接(jie)的(de)(de)設備和工廠造成傷(shang)害。支撐在(zai)單作(zuo)用(yong)垂直約束(shu)(shu)和沒有側向(xiang)約束(shu)(shu)的(de)(de)彈簧上(shang)的(de)(de)管(guan)(guan)道(dao)系統將具有較低的(de)(de)固有振動(dong)(dong)(dong)(dong)頻(pin)率，并(bing)且在(zai)受(shou)(shou)到振動(dong)(dong)(dong)(dong)時(shi)會(hui)經歷較大的(de)(de)動(dong)(dong)(dong)(dong)態(tai)撓度(du)；這(zhe)通常是不可(ke)接(jie)受(shou)(shou)的(de)(de)。通過響應(ying)譜(pu)或時(shi)程(cheng)分析(xi)進(jin)行的(de)(de)管(guan)(guan)道(dao)應(ying)力分析(xi)可(ke)用(yong)于(yu)(yu)顯示對(dui)動(dong)(dong)(dong)(dong)態(tai)約束(shu)(shu)的(de)(de)需求。在(zai)承(cheng)受(shou)(shou)動(dong)(dong)(dong)(dong)態(tai)載荷的(de)(de)管(guan)(guan)道(dao)系統中，可(ke)能(neng)(neng)有使用(yong)在(zai)兩個(ge)方(fang)向(xiang)上(shang)都起作(zuo)用(yong)的(de)(de)剛性支柱，而不是僅使用(yong)向(xiang)下(xia)支撐載荷的(de)(de)吊桿。剛性支柱還用(yong)于(yu)(yu)在(zai)需要時(shi)提供橫(heng)向(xiang)約束(shu)(shu)。在(zai)需要動(dong)(dong)(dong)(dong)態(tai)約束(shu)(shu)的(de)(de)地(di)方(fang)使用(yong)緩沖(chong)劑(ji)，但是允許管(guan)(guan)子熱(re)移動(dong)(dong)(dong)(dong)。
