0.5 meter, 1 meter and 1.5 meters.
The churning control system of the present embodiment executes different actions when cyclone nozzle is in different depth intervals.Specifically
It is as follows：
The actual grade H of cyclone nozzle is sent in controller 11 by depth detection apparatus.
When 1<When H≤1.5 meter, alarm lamp 16 intermittently flickers, and buzzer 17 continuously rings three sound, this alarms for the Ith stage.
When cyclone nozzle is promoted to 0.5<When H≤1 meter, alarm lamp 16 continuously flickers, and 17 continuous interval ring of buzzer, this is
IIth stage alarmed.
When promotion to 0.3<When H≤0.5 meter, 16 high speed scintillation of alarm lamp, 17 continuous ring of buzzer, while slush pump drives
The dynamic automatic reduction of speed of motor is to depressurize, and churning promotes speed and halves, this alarms for the IIIth stage.
16 high speed scintillation of H≤0.3 meter Times warning lamp, 17 continuous ring of buzzer, slush pump driving motor, water are arrived when being promoted
It pumps driving motor, air compressor driving motor to operate with smaller speed, maintains low-pressure state, ensure that pipeline does not block, this is the
IV stage alarmed.
The control system of the jet drill rig of the present embodiment in the cyclone nozzle distance closer apart from ground according to it is different away from
Different alarm signals is sent out preferably to form reminding effect to staff from section.
Alarm can be released by reset button on display, and stage alarm release or this churning process may be selected
Alarm release：
Certainly, releasing control can also be carried out to alarm signal in above each stage：
Alarm lamp 16 and buzzer 17 are resetted and are stopped after the I, the II stage alarm release.
After IIIth stage alarm release, the still high speed scintillation of alarm lamp 16, the reset of buzzer 17 is stopped.Mud pump motor
Rotating speed does not restore, and churning promotes speed and restores.
After IVth stage alarm release, alarm lamp 16, buzzer 17 are resetted and are stopped, slush pump driving motor,
Water pump driving motor, air compressor driving motor are still operated with smaller speed, maintain low-pressure state, ensure that pipeline does not block.
After the alarm release of entire churning process, alarm lamp 16 and buzzer 17 are resetted and are stopped.Mud at this time
It is corresponding by the stage is presently in pump driving motor, water pump driving motor, air compressor driving motor rotating speed and churning promotion speed
Parameter carries out after stage alarm release, and slush pump driving motor, water pump driving motor, air compressor driving motor rotating speed can be manual
It adjusts, but can only reduce.
In summary, the control system of the jet drill rig of the present embodiment may be implemented to be in churning promotion shape to jet drill rig
The rotating speed of power head and promotion speed are carried out automatically controlling to realize precision control when state.And the realization automatically controlled may be used also
To reduce the working efficiency of staff.In addition, actual grade of the control system of the jet drill rig of the present embodiment in cyclone nozzle
When closer apart from ground, the pressure of fluid pump can also be reduced and reduce the promotion speed of cyclone nozzle to prevent high pressure from spraying
Fluid damages staff.And when the actual grade of cyclone nozzle is closer apart from ground, alarm lamp can also be controlled
And/or buzzer sends out alarm signal, plays the role of reminding staff, fluid is further prevented to cause to hinder to staff
Evil.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model rather than limits it
System；Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should
Understand：It can still modify to specific embodiment of the present utility model or some technical characteristics are equally replaced
