詳細介紹

波紋管膨脹節

安(an)裝軸(zhou)(zhou)向(xiang)(xiang)型補(bu)(bu)償(chang)器(qi)的管(guan)(guan)(guan)(guan)(guan)(guan)段,在(zai)管(guan)(guan)(guan)(guan)(guan)(guan)道的盲端、彎頭、變(bian)截面處,裝有截止閥或減壓(ya)(ya)閥的部門及側支管(guan)(guan)(guan)(guan)(guan)(guan)線進入主(zhu)管(guan)(guan)(guan)(guan)(guan)(guan)線入口處,都(dou)要設置(zhi)主(zhu)固(gu)定(ding)管(guan)(guan)(guan)(guan)(guan)(guan)架(jia)。主(zhu)固(gu)定(ding)管(guan)(guan)(guan)(guan)(guan)(guan)架(jia)要考慮波紋(wen)管(guan)(guan)(guan)(guan)(guan)(guan)靜壓(ya)(ya)推(tui)力(li)(li)及變(bian)形(xing)彈性力(li)(li)的作用(yong)。推(tui)力(li)(li)計(ji)算(suan)公(gong)式如(ru)下: Fp=100*P*A Fp-補(bu)(bu)償(chang)器(qi)軸(zhou)(zhou)向(xiang)(xiang)壓(ya)(ya)力(li)(li)推(tui)(N), A-對應于波紋(wen)平均直徑的有效面積(cm2), P-此管(guan)(guan)(guan)(guan)(guan)(guan)段管(guan)(guan)(guan)(guan)(guan)(guan)道最高(gao)壓(ya)(ya)力(li)(li)(MPa)。 軸(zhou)(zhou)向(xiang)(xiang)彈性力(li)(li)的計(ji)算(suan)公(gong)式如(ru)下: Fx=f*Kx*X FX-補(bu)(bu)償(chang)器(qi)軸(zhou)(zhou)向(xiang)(xiang)彈性力(li)(li)(N), KX-補(bu)(bu)償(chang)器(qi)軸(zhou)(zhou)向(xiang)(xiang)剛(gang)度(N/mm); f-系數,當(dang)"預(yu)變(bian)形(xing)"(包括預(yu)變(bian)形(xing)量△X=0)時,f=1/2,否則f=1。 管(guan)(guan)(guan)(guan)(guan)(guan)道除上述部位外(wai),可設置(zhi)中(zhong)間(jian)固(gu)定(ding)管(guan)(guan)(guan)(guan)(guan)(guan)架(jia)。中(zhong)間(jian)固(gu)定(ding)管(guan)(guan)(guan)(guan)(guan)(guan)架(jia)可不(bu)考慮壓(ya)(ya)力(li)(li)推(tui)力(li)(li)的作用(yong)。
