瑞典阿特拉斯·考普科公司生产的用于采矿、勘探和其他场合的潜孔冲击器的品种范围现在又扩大了。公司以前不能提供φ152mm(6英寸)以上的冲击器,现在新一代的重型冲击器正在推广,牌号为COP8、COP10和COP11。这类冲击器钻凿的炮孔尺寸为φ85～445mm(3(3/8)～17(1/2)英寸)。新的COP系列冲击器为高性能无阀冲击器,使用压力达2.5MPa。由于设计无内缸衬套,因此,冲击器活塞面积大。大面积大功率活塞使冲击器可提供更大的能量,因而
The range of varieties of downhole impactors manufactured by Atlas Copco Sweden for mining, exploration and other applications is now expanded. Previously, the company was unable to provide impactors of φ152mm (6 inches) or more. Now a new generation of heavy-duty impactor is being promoted as COP8, COP10 and COP11. Drum holes drilled by this type of impactor have a size of φ85 to 445 mm (3 (3/8) to 17 (1/2) inches). The new COP series of impactor for high-performance valveless impactor, the use of pressure up to 2.5MPa. Due to the design without the cylinder liner, therefore, the impactor piston area. Large-area high-power piston allows the impactor can provide more energy, thus
