钢钻头结构


(1)该系列三牙轮钻头使用滑动轴承。 硬面头轴承表面。 锥轴承镶嵌有减摩合金,然后镀银。 轴承的负载容量和耐发热胶着性得到很大提高。

(2)。 O形圈密封件由越耐磨性高饱和丁腈橡胶的与增加的密封部和精确设计在锥形密封区域的密封凸缘增加了密封的可靠性。

(3)。 该位轴承可锁定球

(4)。 对于钢齿位,齿面是硬面与新型磨损resistan的


特征

1.强制平衡,抗蚀剂在高速钻探冲击到叶片,使位工作稳定。

2.切刀是高性能提高抗冲击和抗磨料的能力。

3.优化水力DESIGH,移动方便了钻屑和冷却。

4.配有背扩孔牙齿。

Steel drill bit structure


(1) This series tricone bit use Journal bearing. Hardfaced head bearing surface. Cone bearing inlaid with friction reducing alloy and then silver-plated. The load capacity and seizure resistance of the bearing is greatly improved.

(2) . O ring seal is made of the more wear resistance high saturated buna-N with the increased seal section and precisely designed sealing flange in the cone sealing area increased the reliability of the seal.

(3) . The bit bearing can be ball locked

(4) . For steel tooth bit, the tooth surface is hardfaced with new type of wear resistan


Features

1. Force balanced, resist impact to the blade during high-speed drilling, to make bit work stable.

2. The cutter is high performance to increase the ability of anti-impact and anti-abrasive.

3. Optimal hydraulic desigh, easy to move out the drill cuttings and cooling.

4. Equipped with back reaming teeth.
