Definitions

  • rock drilling machines are used for drilling bore holes into rock surfaces.
  • the rock drilling machine comprises a rotating device for rotating a drilling tool during drilling.
  • Flushing systems have been developed for feeding flushing fluid through the tool to the drill bit and further to the bottom of the drill hole.
  • flow of flushing fluid is adjusted by means of adjusting valves, which are designed especially for the purpose.
  • these known flushing systems have some drawbacks.
  • the method according to the invention is characterized by controlling flow rate of the flushing fluid by adjusting pressure supplied by the pump unit; directing the flushing fluid through at least two valves being operationally parallel and having flow paths which are different in size; and selecting opening and closing of the at least two valves in response to magnitude of the produced volume flow of the pump unit.
  • An idea of the disclosed solution is that flushing fluid is fed from a pump unit to a drilling unit for flushing drilling cuttings away from a bore hole being drilled. Flow rate flowing to the drilling unit is adjusted by controlling pumping of the flushing fluid.
  • At least one feed duct of the flushing system is provided with a control valve and a throttle.
  • the throttle is an integrated element of the valve.
  • the throttle is a constructive part of the structure of the valve whereby no separate throttle element or device is needed.
  • the structure may then be compact.
  • produced flow rate of a feed duct is adjusted by adjusting operating speed of the pump.
  • the pump is driven by an electrical motor and the speed of the motor is adjusted by means of a frequency converter.
  • the frequency converter allows an accurate control of rotational speed. Further, the frequency converter is a reliable component.
  • the flushing system comprises one or more control units for controlling feed of the flushing fluid.
  • the control unit may comprise one or more processing devices for implementing the control.
  • the control unit may be provided with one or more predetermined control principles for the operation of the flushing system.
  • the control principle may be stored in memory storage of the control unit or it may be retrieved from an external data source.
  • the control unit is configured to determine control parameters in the processing device on the basis of the received sensing data and the control principle.
  • the sensing data may be received from one or more sensing devices arranged to measure and detect properties of the fed flushing fluid.
  • the predetermined control principle may be configured to control feeding of the flushing fluid by utilizing a flow control principle, which is disclosed in this patent application. Another control principle may be configured to monitor drilling procedure on the basis of the sensed data. Further still, an alternative control principle may be configured to detect failures in the flushing system.
  • the rock drilling machine of the drilling unit is a down-the-hole (DTH) drilling machine comprising a rotating unit and a percussion unit arranged at opposite ends of a tool.
  • DTH down-the-hole
  • the disclosed flushing system and method may be applied in DTH -drilling.
  • the rock drilling machine of the drilling unit is a rotary drilling machine comprising a rotating unit.
  • the rotary drilling machine is without any percussion device.
  • the disclosed flushing system and method may be applied in rotary drilling.
  • the control unit CU may control pumping of the flushing fluid.
  • the power device 18 may be a hydraulic motor connected to a hydraulic system 20.
  • the pumping unit 15 may comprise an adjusting device 21 allowing rotational speed of the hydraulic motor and the pump 19 to be adjusted.
  • the control unit CU may control the adjusting device 21 and the valve 17.
  • the power device 18 may an electrical motor and the adjusting device 21 may be a frequency converter.
  • the feed duct 16 may be provided with an optional pressure sensing device P for detecting prevailing pressure of the feed duct 16.
  • the pressure sensing data may also be transmitted to the control unit CU. Thanks to the pressure sensing data, it is possible to set the pressure of the flushing fluid as high as tolerated by the drilling unit 4.
  • the pressure data may also utilized for detecting changes in the rock material being drilled.
