机电设备隔爆接合面安全检查要点

接合面的结构参数应符合GB3836.2－2000Ι类隔爆接合面结构参数的规定。
1）快动式门或盖的隔爆接合面的最小有效宽度须不小于25mm；
2）靠外壳壁支撑的操纵杆或轴，其接合面宽度应不小于最小结合面宽度；
3）操纵杆或轴的直径应符合最小接合面宽度，其接合面宽度应不小于操纵杆或轴的直径，但不大于25mm；
4）当操纵杆与杆孔配合间隙因磨损而增大时，可采取在杆孔处嵌镶衬套等措施进行修复。特殊情况下，加设一个正常使用中不易磨损的封盖；
5）在检修中除去隔爆接合面的法兰厚度，不得超过维修余量的数值；
6）隔爆接合面表面平均粗糙度Ra≤6.3μm,操纵杆表面粗糙度不大于Ra≤3.2μm；
7）隔爆接合面有防锈措施，如电镀、磷化、涂204-1防锈油等，但不准涂油漆。
