Description

Automatic oil supply device for cone palm

Technical Field

The utility model relates to a roller bit technical field specifically is automatic oil supply device of roller bit palm.

Background

At present, the supply of the roller bit lubricating oil is mainly realized by that after the drilling reaches a certain depth in the working process of the bit, the pressure of injected water in a working environment well is applied to an oil storage bag at an oil injection port part to ensure that the bearing part in the bit keeps the lubricating function, and when the depth is shallow or no water is used, the pressure applied to the oil storage bag is very small, so that the supply of the lubricating oil on the bearing surface of the bit cannot be ensured. For this purpose, we propose an automatic oil supply device for cone legs.
