CIR70/90/110
CIR Series Hammers
CIR Series hammers are low pressure hammers with valves. Each of them has single piston and is flushed from the center. They are driven by compressed air. In order to prevent dust pollution, you could also add high pressure water into the compressed air. Main types: CIR70, CIR90 and CIR110
CIR系列冲击器具有以下特点:
1. 活塞与钻头重量比接近1:1,有效作用时间长,有利于提高岩石破碎效率并延长钻具寿命;
2. 冲击器带有逆止阀装置,可在水中钻凿炮孔;
3. 中心排气排渣效果好,减少了岩石的重复破碎;
4. 冲击器外套管采用了新的热处理硬化工艺,提高了耐磨性;
5. 活塞采用了喷丸强化工艺,有效提高了活塞寿命;
6. 配用钻头选用了优质合金柱,增强了冲击器的寿命和凿岩速度。
