How to Extend Longevity of Tricone Bit?

In heavy industries such as mining and oil drilling, rollers, as the core components for rock crushing and power transmission, have a direct impact on construction efficiency and costs. The key factor determining roller performance lies in the quality of lubricating oil injection—and the emergence of roller vacuum oiling technology has completely solved the pain points of traditional oiling methods, becoming an "invisible hero" in improving equipment reliability.

Traditional oiling relies on gravity or pressure to push oil, which easily forms gaps inside the roller, leading to insufficient lubrication on metal contact surfaces. Meanwhile, residual air accelerates oxidative rusting of components. The core advantage of vacuum oiling technology lies in using a negative pressure environment to completely extract air from the roller, allowing oil to uniformly penetrate every gear meshing surface and bearing gap under pressure, achieving "no-dead-angle" lubrication. This method can increase the oil filling rate to over 98%, fundamentally reducing wear risks.

For construction enterprises, the value of this technology is particularly significant. In deep hole drilling scenarios, rollers using vacuum oiling can extend their service life by more than 30%, reducing the frequency of shutdowns for replacement. In dusty and humid mining environments, the more airtight oiling effect can effectively block impurity intrusion and lower equipment failure rates. Actual data from an iron ore mine shows that after applying this technology, roller maintenance costs decreased by nearly 40% and construction efficiency increased by 15%.

With intelligent upgrading, vacuum oiling equipment has realized precise control of oil injection volume and data traceability. Combined with the roller working condition monitoring system, it can form a full-cycle management of "injection-operation and maintenance-replacement". This seemingly basic technological innovation is actually a microcosm of the transformation of heavy industry from "extensive operation and maintenance" to "precision guarantee", providing solid support for cost reduction and efficiency improvement in the equipment manufacturing and construction industries.
