北京型转盘钻机,经几年的使用,我们认为性能很好,但也感到这种钻机的转盘密封不严,工作时泥浆容易流进转盘体内,使机油变质、轴承磨损严重.几年来,我队机修车间经反复试验,找到了一种较理想的密封方法,如图所示.主要是将转盘大盖(7)作了改制,即把易进泥浆的进口处加工成60°的斜坡(6),在斜坡(6)的上部又加工成15°的挡檐(2),紧接挡檐(2)的顶部则加工成封闭圆环(3)将背帽盖住.罩盖(4)原为套装,易进泥浆;
Beijing type rotary drilling rig, after several years of use, we think that the performance is very good, but also felt that this drill turntable seal lax, mud easily flow into the turntable body during the work, so that the oil deterioration, bearing wear serious.For several years, I After repeated tests, the team found a better sealing method as shown in the figure, which mainly reformed the large cover (7) of the turntable, that is, processed the entrance of the mud into the slope of 60 ° 6), a 15-degree canopy (2) is formed on the upper part of the ramp (6), and the top of the canopy (2) ) For the original package, easy to enter the mud;
