【摘要】 为配合瓦斯抽采钻孔化学材料封孔注浆,探求更加简单、有效的封孔设备,研制了新型瓦斯抽采钻孔封孔双液注浆泵,该装置将传统双液气动注浆泵气体做功促使机械做功简化为气体直接做功,结构简单,控制方便。更多还原

【Abstract】 In order to explore more simple and effective sealing technology and combine with the gas drainage hole sealing with chemical materials, a new pneumatic dual fluid injection pump was developed. This device simplify air pressure-driven mechanical movement of traditional dual fluid injection pump with air pressure-driven, and its mechanism is of simple construction, which is convenient to control.更多还原
