安裝軸向(xiang)型補償(chang)器的(de)(de)管(guan)(guan)(guan)(guan)段，在管(guan)(guan)(guan)(guan)道(dao)的(de)(de)盲端、彎頭、變(bian)截面處，裝有截止(zhi)閥或減壓(ya)(ya)(ya)閥的(de)(de)部門(men)及側支(zhi)管(guan)(guan)(guan)(guan)線(xian)進入主管(guan)(guan)(guan)(guan)線(xian)入口(kou)處，都要設(she)置主固定(ding)管(guan)(guan)(guan)(guan)架。主固定(ding)管(guan)(guan)(guan)(guan)架要考慮波紋(wen)管(guan)(guan)(guan)(guan)靜壓(ya)(ya)(ya)推力(li)及變(bian)形彈性(xing)(xing)力(li)的(de)(de)作用(yong)。推力(li)計算公(gong)式如下: Fp=100*P*A Fp-補償(chang)器軸向(xiang)壓(ya)(ya)(ya)力(li)推(N)， A-對應于波紋(wen)平均直(zhi)徑的(de)(de)有效面積(ji)(cm2)， P-此管(guan)(guan)(guan)(guan)段管(guan)(guan)(guan)(guan)道(dao)最高壓(ya)(ya)(ya)力(li)(MPa)。 軸向(xiang)彈性(xing)(xing)力(li)的(de)(de)計算公(gong)式如下: Fx=f*Kx*X FX-補償(chang)器軸向(xiang)彈性(xing)(xing)力(li)(N)， KX-補償(chang)器軸向(xiang)剛度(N/mm); f-系數，當"預(yu)變(bian)形"(包括(kuo)預(yu)變(bian)形量△X=0)時，f=1/2，否則f=1。 管(guan)(guan)(guan)(guan)道(dao)除上述(shu)部位外，可(ke)設(she)置中間固定(ding)管(guan)(guan)(guan)(guan)架。中間固定(ding)管(guan)(guan)(guan)(guan)架可(ke)不(bu)考慮壓(ya)(ya)(ya)力(li)推力(li)的(de)(de)作用(yong)。
