ZP-205转盘润滑密封装置的改进与应用

Improvement and Application of Lubrication Seal Device for ZP-205 Rotary Table

转盘作为钻机的主要驱动装置之一,可为钻具提供持续的转矩、转速等,在钻井过程中发挥着重要作用。总结多年现场施工经验后发现,除安装误差等方面引起的转盘轴承磨损外,密封装置润滑效果不良也是导致轴承磨损的主要原因。因此,在不改变转盘主要结构和性能基础上,通过设计刚性材质的封闭式挡泥装置、改进固定方式等技术措施,形成一套改进型ZP-205转盘润滑密封装置。在现场应用过程中,该装置使油池内润滑油更换时间由2个月延长至6个月,轴承使用寿命延长25%以上,节约了润滑油使用量和转盘维修成本,缩短了钻进周期,创造了较好的经济效益。ZP-205转盘密封装置可广泛应用于ZJ15和ZJ30钻机,大庆油田目前有ZJ15和ZJ30钻机100部以上,全部配备该密封装置可以取得更好的经济效益和社会效益。

As one of the main driving devices of the drilling rig,the rotary table can provide continuous torque and speed for the drilling tool,which plays an important role in the drilling process.After summarizing many years of field construction experience,it is found that in addition to the wear of turntable bearing caused by installation error,poor lubrication effect of sealing device is also the main cause of bearing wear.Therefore,on the basis of not changing the main structure and performance of the turntable,through the design of rigid material closed mud retaining device,improvement of the fixing way and other technical measures,this paper designs a set of improved ZP-205 turntable lubrication seal device.In the field application process,the device makes the oil in the oil pool to replace the oil once every 2 months to once every 6 months,the bearing service life extended by more than 25%,which saves the use of oil and turntable maintenance costs,shortens the drilling cycle,and creates better economic benefits.ZP-205 rotary seal device can be widely used in ZJ15 and ZJ30 drilling RIGS.Daqing oilfield currently has more than 100 ZJ15 and ZJ30 drilling RIGS which are all equipped with this seal device and achieves better economic and social benefits.
