安裝軸(zhou)向型補償(chang)器(qi)(qi)的管(guan)(guan)段(duan)(duan),在管(guan)(guan)道(dao)的盲端、彎頭、變(bian)(bian)截(jie)面處,裝有(you)截(jie)止(zhi)閥或減壓閥的部門及側支(zhi)管(guan)(guan)線(xian)進入(ru)主管(guan)(guan)線(xian)入(ru)口處,都要設置主固(gu)定(ding)管(guan)(guan)架(jia)(jia)(jia)。主固(gu)定(ding)管(guan)(guan)架(jia)(jia)(jia)要考慮波紋管(guan)(guan)靜(jing)壓推(tui)力及變(bian)(bian)形彈性(xing)力的作用。推(tui)力計算公式(shi)如下: Fp=100*P*A Fp-補償(chang)器(qi)(qi)軸(zhou)向壓力推(tui)(N), A-對應于波紋平均直徑的有(you)效(xiao)面積(cm2), P-此管(guan)(guan)段(duan)(duan)管(guan)(guan)道(dao)最高壓力(MPa)。 軸(zhou)向彈性(xing)力的計算公式(shi)如下: Fx=f*Kx*X FX-補償(chang)器(qi)(qi)軸(zhou)向彈性(xing)力(N), KX-補償(chang)器(qi)(qi)軸(zhou)向剛度(du)(N/mm); f-系數,當"預(yu)變(bian)(bian)形"(包(bao)括(kuo)預(yu)變(bian)(bian)形量(liang)△X=0)時,f=1/2,否則(ze)f=1。 管(guan)(guan)道(dao)除上述部位外,可(ke)設置中間(jian)固(gu)定(ding)管(guan)(guan)架(jia)(jia)(jia)。中間(jian)固(gu)定(ding)管(guan)(guan)架(jia)(jia)(jia)可(ke)不(bu)考慮壓力推(tui)力的作用。
