       一般来说,设备安装都要考虑到一个安装规范,因为安装如果不规范就会导致设备不能使用,或者达不到使用效果。所以设备安装要仔细。下面就管道安装规范进行解读。

       1、管道敷设时,管子外壁与相邻管道的管件边缘距离不应小于10mm;同排管道的法兰或活接头相互错开的距离应大于等于100mm;穿墙管道应加套管,其接头位置与墙面的距离宜大于800mm。

       2、管道直管段支架间距,宜符合下表的规定。弯曲段的管道,应在起弯点附近增设管道支架。

       支架间距500-1000 1000-1500 1500-2000 2000-3000 3000-5000

       3、管道的坐标位置、标高的允许偏差为±10mm;管道的水平度或铅垂度偏差不应大于2/1000。

       4、气动系统的支管宜从主管的顶部引出;长度超过5m的气动支管路,宜设大于10/1000顺气体流动方向的向下坡度。

       5、润滑油系统的回油管道,应设12.5/1000~25/1000向油箱方向的向下坡

       软管的安装,应符合下列要求∶

       1.外径大于30mm的软管,其比较小的那个弯曲半径不应小于管子外径的9倍;外径小于等于30mm的软管,其比较小的那个弯曲半径不应小于管子外径的7倍;

       2.软管与管接头的连接处,应有一段直管段,其长度不应小于管子外径的6倍;

       3.在静止及随机移动时,均不得有扭转变形现象;

       4.软管长度过长或受较强振动时,宜用管卡夹牢;

       5.当自重会引起较大变形时,应设支托或按其自垂位置进行安装;

       6.软管长度除满足弯曲半径和移动行程外,尚应留有4%的余量;

       7.软管相互间及与其他物件不应有摩擦现象;靠近热源时,必须有隔热措施。

       6、管道的酸洗、冲洗与吹扫

       液压、润滑管道的除锈,应采用酸洗法。管道的酸洗,应在管道配置完成,且已具备冲洗条件后进行。

       7、油库或液压站内的管道,宜采用槽式酸洗法;从油库或液压站至使用点或工作缸的管道,宜采用循环酸洗法。

       8、槽式酸洗法

       管道放入酸洗槽时,宜大管在下、小管在上

       9、循环酸洗法

       1.组成回路的管道长度,宜根据管径、压力和实际情况确定,但不宜超过300m;回路的构成必须使所有管道的内壁全部接触酸洗液;

       2.管道系统内必须充满酸洗液,管道系统的较高的那个部位应设排气点;较低的那个部位应设排放点,管道中的死点宜处于水平位置,其排放口应向下;当酸洗各工序需要交替时,应松开死点接头,并应排除死点内上一工序留存的液体;

       3.酸洗后的管道系统中应通人中和液进行冲洗,并应冲洗至出口溶液不呈酸性为止。
