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。 In order to cooperate with the sealing and injecting grouting of gas drainage and drilling chemical materials and to seek more simple and effective sealing equipment, a new type of gas pumping drilling and sealing double-liquid grouting pump was developed. The device combines the traditional two-fluid pneumatic grouting pump Gas work to promote the mechanical work done to simplify the work done directly to the gas, the structure is simple, easy to control.
