In DTH drilling, the percussion mechanism – commonly called the hammer – is located directly above the drill bit. The drill pipes transmit the necessary feed force and rotation to the hammer and the bit, along with the fluid (air, water or drilling mud) used to actuate the hammer and flush the cuttings. The drill pipes are added to the drill string successively behind the hammer as the hole gets deeper.
[pdf] Firstly, check the pressure before and after the separation of the Kaishan air compressor, as well as whether there is any air leakage in the manual valve and the regulating solenoid valve 2SV; Then check for leaks in the gas pipeline, whether all butterfly valves are open, whether the intake regulator is working properly, whether solenoid valves 3SV and 8SV are leaking, and whether the pressure switch IPS needs to be readjusted.
[pdf] This manual describes the safety precautions, structure and functions of all systems and components, as well as the operation and maintenance methods for the KHE series rotary screw air compressors. The owner and operator shall read the manual carefully.
