产品型号及结构 Type And Structure | MHG637Q，随机排布的锥球齿，实现对开挖断面破岩击碎合覆盖，可以最大限度降低因焊接位置精准度造成的影响. The gauge and the inner row inserts:conical sphericalT The random distribution of inserts can cover the broken rock of the excavation section.Canminimize the impact of site installation position accuracy. |
安装说明 Assembly Instruction | 焊接式安装方式,掌背相对筒体的倾斜角度3~5°，保证牙轮安装在同一圆周，牙轮钻头高度一致，焊接时建议牙轮浸没在水中或焊接要采用间断焊接控制温度，避免高温损伤密封系体. Welding installation mode,the angle of inclination of the back of the lug to the cylinder is 3~5 degrees.Ensure that the roller bit is installed in the same circumference, the height of the cone bit is the same level.During welding,it is strongly suggested that the roller bit should be immersed in water or welded by intermittent operating to avoid high temperature to damage sealing system. |
适用工况 Suitable Operating Mode | 适用于抗压强度30~180MPa岩石地层，如强、中、微风化花岗岩、盐岩、片岩、硬石膏、砂岩、软石灰岩、板岩、页岩、凝灰岩、砾岩、白云岩、石英斑岩等。 Suitable for compressive strength 30~180 mpa lithostratigraphy, such as strong, medium,micro-weathering granite,salt rock,schist,anhydrite,sandstone,soft limestone, slate,shale,tuff,conglomerate,dolomite,quartz porphyry,etc. |
