液压带压开孔机

自动液压开孔钻动力源为液压泵站，液压传动对 带水作业无触电隐患、带气带油作业无火花及电 磁干扰等爆炸风险，可实现自动进刀完成带压开 孔作业。

The power source for automatic hydraulic hot tapping is the hydraulic pump station. The hydraulic transmis sion has no electric shock hazard for operations with water, and there is no risk of explosion such as sparks and electromagnetic interference for operations with air and oil. It can achieve automatic cutting to complete pressurized drilling operations.

动力源也可直接利用工地上的挖掘机 、推土机等液压系统（在工作压力、流 量相符的情况下需定制）为动力源，安全简便。

The power source can also be directly used from hydraulic systems such as excavators and bulldozers on the construction site (customized when the working pressure and flow rate match), which is safe and convenient
