介绍一种新型旋挖钻机销轴润滑脂,该润滑脂通过对稠化剂、极压减磨剂、基础油等组分进行合理的复配和筛选试验研发而成,具有优良的极压减磨性、高低温性以及机械安定性等性能,且各项性能指标达到或超过相应国家标准及原用E P脂水平。经过现场实际应用验证,该产品满足施挖钻机的使用要求,有效克服了销轴轴套的磨损现象,取得了良好的技术和经济效果。
A new type of rotary drilling rig pin shaft grease is introduced. The grease is developed through rational compounding and screening tests on components of thickening agent, extreme pressure and antifriction agent, base oil and the like, and has excellent extreme pressure reduction Grinding, high and low temperature and mechanical stability and other properties, and the performance indicators meet or exceed the corresponding national standards and the original EP fat level. After field practical verification, the product meets the requirements of the application of the digging rig and effectively overcomes the wear phenomenon of the pin shaft sleeve and achieves good technical and economic results.
