我队机修人员,针对北京型钻机转盘在回转中(尤其是快速回转中)的甩油现象,进行了研究,采取了改进措施,效果良好,其具体方法如下:一、转盘箱体凹槽加深:北京600型钻机箱体原来凹槽深为9毫米(图1左),我们将它加深为25毫米(图1右). Our team of mechanics, for the Beijing-type rig turntable in the slewing (especially the rapid rotation) Oil thrown phenomenon, carried out research, to take measures to improve the effectiveness of its specific methods are as follows: First, the turntable groove deepen : Beijing 600 drilling rig box depth of the original groove 9 mm (Figure 1 left), we deepen it to 25 mm (Figure 1, right).
