实践表明,在穿孔过程中,对牙轮钻头的轴承进行润滑能延长钻头支座的寿命。业已确认,为进行钻头轴承润滑,采用接杆时在每根钻杆内壁涂以浓稠润滑油(如索里多润滑脂)的方法是可行的。在无专门润滑装置的情况下,必须用这种方法对牙轮轴承进行润滑,因为在制造厂装配钻头时往牙轮腔内涂抹的石墨润滑脂,主要起钻头库存期内封住轴承的作用,而在钻凿第一个炮孔时即被冲洗介质从轴承上带走。这种方法并非十分有效。所以,为了在穿孔过程中不断给牙轮轴承注油,已研制并在使用多种注油器,它们既可安装在钻头内,也可安装在钻机总 Practice shows that in the process of perforation, roller cone bearing lubrication can extend the life of the drill holder. It has been confirmed that for drill bearing lubrication, it is possible to apply a thick lubricating oil (such as Solidol) to the inner wall of each rod when using the rod. In the absence of a special lubrication device, the roller bearing must be lubricated in this way because the graphite grease applied to the cavity of the cone when the drill bit is assembled at the factory functions mainly as a bearing seal during inventory , And was flushed from the bearing while drilling the first borehole. This method is not very effective. Therefore, in order to continue to perforate the cone bearing oil injection has been developed and the use of a variety of oiler, they can be installed in the drill bit can also be installed in the rig total
