Something about the structural characteristics of the oil drill


Floating bearing structure, the floating element made of new materials of high strength, high flexibility, high temperature resistance, high wear resistance characteristics is made, the surface of the solid lubricant processing.

Vice-reducing bearing relative linear velocity while reducing friction surface temperature, can effectively improve the bearing life and reliability of the bearings under high pressure or high speed drilling drilling process conditions.

High-precision metal seal. Metal sealed by a careful design and processing metal sealing ring as bearing axial dynamic seal.

Two high elastic rubber energizing ring are located in the teeth palm and cone sealing area as a static seal, seal compression optimized to ensure that the two metal ring seal surface always maintain good contact.

Ball locking cone, adapt to high speed.

Limit the use of pressure and prevent drilling fluid into the lubrication oil system-wide rubber bladder, the bearing lubrication system provides a good guarantee.

Use can withstand 250 ° C high temperature, abrasion resistance of new grease.

Tipped drill using high strength and high toughness carbide gear, optimize the design of the number of rows of teeth, teeth, toothy height and unique alloy tooth shape, give full play to the tipped drill bit high wear resistance and excellent cutting ability.

Steel teeth drill tooth face apply welding new wear-resistant materials, steel tooth bit while maintaining high ROP, improved bit cutting teeth life.
