在毛主席革命路线的指引下,本钢南芬露天铁矿和东北工学院参加研制工作的同志,坚持独立自主,自力更生方针,大搞内外三结合,在总结国内外冲击器结构特点和使用情况的基础上,结合我国国情,设计制造了适应大中型露天矿山使用的W-200型潜孔无阀冲击器。工业试验表明,W-200型潜孔无阀冲击器是一种新型的冲击器,具有结构简单,加工方便,钻孔效率高,故障少,使用维护比较方便等优点。
Under the guidance of Chairman Mao’s revolutionary line, comrades participating in the research and development work of Benxi Iron & Steel Nanfing Open-pit Iron Mine and Northeastern Institute of Technology have adhered to the principle of independence and self-reliance and vigorously engaged in the combination of inside and outside. After summarizing the structural features and usage of the impactor at home and abroad Based on the combination of China’s national conditions, design and manufacture of large and medium-sized open pit to adapt to the use of W-200 DTH valve-free impactor. Industrial tests show that the W-200 DTH valveless impactor is a new type of impactor, which has the advantages of simple structure, convenient processing, high drilling efficiency, less trouble, more convenient operation and maintenance.
