241 毫米协 737 G 石油钻头钻头 (橡胶密封轴承)
结构特点:
1，滑动轴承形式。棕榈轴承表面堆焊层的硬合金齿、 锥轴承与减少焊接在一起的金换银后、 提高承载能力和抗咬能力;
2，轴承的类型 O 密封环是耐磨、 高耐高温高饱和丁腈橡胶，增加密封的环形截面减少了密封的压力，精心设计的密封凸平台外提高的密封的可靠性。
3，利用钢球或卡锁芦苇锥方式，卡锁可以忍受高芦苇钻压，钢球锁可以适应高速度。
4 微分压力和防止钻井流体限制润滑系统中所有的橡胶油存储囊，为轴承系统提供良好的润滑保证。
5，250 ° C 温度耐高温、 抗磨损性的新的润滑剂。
6，踏钻使用高强度和高韧性硬质合金齿轮，优化的齿排数、 齿轮、 露齿高度和独特的合金齿形设计，充分发挥集的英尺高的耐磨性和优秀钻头的切削能力。统治者钻头齿面适用焊接的新型耐磨材料，和在同一时间，保持机械钻钻头标尺机械钻速提高钻钻头切削齿寿命。
产品优势:
医管局 O 形式橡胶密封滑动系列钻头轴承钻头，在日常使用中能承受高钻速的压力，与不同的切割结构，能适应非常软、 硬地层。

241mm IADC 737G oil drill bit bit (rubber seal bearing)
Structure features:
1, the sliding bearing form. Tooth palm bearing surface surfacing layer of hard alloy, cone bearing with reduced after welding together gold for silver, improve the bearing capacity and resistance to bite ability;
2, bearing type O sealing ring is wear-resistant, high temperature resistant high saturation NBR, increase the sealing ring section reduces the pressure seal, carefully designed sealing convex platform outside the improved seal reliability.
3, USES the steel ball or card lock reed cone way, card lock can endure high reed drilling pressure, steel ball to lock the can adapt to high speed.
4 the differential pressure and prevent drilling fluid restrictions in the lubricating system all rubber oil storage sac, for bearing system provides good lubrication guarantee.
5, 250 ° C temperature the high temperature, abrasion resistance of new grease.
6, set foot drill using high strength and high toughness carbide gear, optimize the design of the tooth row number, gear, toothy height and unique alloy tooth shape, give full play to the set feet high wear resistance and excellent bit of cutting ability. Ruler bit tooth face apply welding new wear-resistant materials, and to maintain the mechanical drill bit ruler speed at the same time, improve the drill bit cutting teeth life.
Product advantage:
HA series bit for O form rubber sealing sliding bearing drill bit, in a routine use can withstand high speed drilling of pressure, with different cutting structure, can adapt to a very soft and hard strata.
| Bit size | IADC | Application | Cutting structure | pressure kN/ mm | speed r/ min |
| 241mmmmHA737G | 737 | Grinding of high formation; such as a hard limestone; dolostone; hard sandstone; flint; etc
| Big circular arc form of teeth in row, spherical discharge teeth | 0.70- 1.20 | 70- 40 |
Packing: plastic bag inside, wooden case/ box outside.
