安裝軸向(xiang)(xiang)型補(bu)(bu)償器的管(guan)(guan)段，在(zai)管(guan)(guan)道的盲端、彎頭、變(bian)(bian)(bian)截(jie)面(mian)處，裝有(you)截(jie)止(zhi)閥或(huo)減(jian)壓閥的部門及(ji)側支管(guan)(guan)線進入主(zhu)管(guan)(guan)線入口處，都要設置主(zhu)固(gu)定(ding)管(guan)(guan)架。主(zhu)固(gu)定(ding)管(guan)(guan)架要考慮波紋(wen)管(guan)(guan)靜壓推(tui)(tui)力(li)及(ji)變(bian)(bian)(bian)形(xing)(xing)彈(dan)性(xing)力(li)的作用。推(tui)(tui)力(li)計算公式(shi)如(ru)下(xia): Fp=100*P*A Fp-補(bu)(bu)償器軸向(xiang)(xiang)壓力(li)推(tui)(tui)(N)， A-對應于波紋(wen)平(ping)均(jun)直徑的有(you)效面(mian)積(cm2)， P-此管(guan)(guan)段管(guan)(guan)道最高(gao)壓力(li)(MPa)。 軸向(xiang)(xiang)彈(dan)性(xing)力(li)的計算公式(shi)如(ru)下(xia): Fx=f*Kx*X FX-補(bu)(bu)償器軸向(xiang)(xiang)彈(dan)性(xing)力(li)(N)， KX-補(bu)(bu)償器軸向(xiang)(xiang)剛(gang)度(N/mm); f-系數，當"預(yu)變(bian)(bian)(bian)形(xing)(xing)"(包括預(yu)變(bian)(bian)(bian)形(xing)(xing)量(liang)△X=0)時，f=1/2，否則f=1。 管(guan)(guan)道除上(shang)述部位外，可設置中間固(gu)定(ding)管(guan)(guan)架。中間固(gu)定(ding)管(guan)(guan)架可不考慮壓力(li)推(tui)(tui)力(li)的作用。
