潜孔钻机KQ-200电气控制系统稳定性高、操作方便。钻机供风采用的25m3螺杆空压机自耦降压起动,同时具有超温、超压自动停车保护,其设计合理、经济。潜孔钻机由于工作环境相当恶劣,粉尘较多,因此机油散热器散热片经常被灰尘堵住而影响空压机散热,从而引起超温自动停车。更为严重 DTH drilling rig KQ-200 electrical control system, high stability, easy to operate. 25m3 screw air compressor used for air supply of the drilling machine is self-coupled buck-starting, meanwhile it has over-temperature and overpressure automatic parking protection, and the design is reasonable and economical. DTH drilling rig due to the working environment is rather harsh, more dust, so the oil radiator heat sink is often blocked by dust and affect the air compressor heat, causing over-temperature automatic parking.
