Don t drill faster than 15 minutes for 1 stand 钻进速度别超过15分钟1根立柱
Select the best penetration rate 选择最佳钻进速度
High quality vacuum plating and best prescription of diamonds , made our products have a high speed and long life 高品质镀膜金刚石与先进配方,使得钻进速度快月-寿命长。
Application of downhole hydrodynamic propulsors solves the problem of exerting wob , and are helpful to enhancing penetration rate 井下液力推进器的应用在一定程度上解决了钻压的施加问题,有利于提高钻进速度。
1 . setting a measure device on the drilling machines , a new method of gaining the characters of rock and soil from the blasting drilling is gotten , which is economic and accurate and from which the characters of different parts of the blasting hole are got accurately 取得的主要成果如下: ( 1 )在钻孔机械上附加一测量钻孔钻进速度装置,通过在土岩爆破施工现场直接从爆破钻孔的钻进过程来实时获取炮孔不同部位的岩石性质。
