Rig the main motor heating equipment: top drive apparatus main motor heater power is normal and how much money the main motor is not running tunnel drilling rig, the heating of the motor can be [] switch, start and stop the heater by PLC / MCC on the door, through the PLC / MCC cabinet heater LEDs indicate operating status. PLC system is normal, the heater and the main motor chain. If you start the main motor at the heater, the heater will automatically stop running. The main motor is running, you can not start the heater. Rig the main motor cooling fan: top drive unit cooling fan installed in the upper end of the main motor. Driller console of [fans] switch toppled the "on" position, will directly start the main motor fan. [Fan] switch toppled the "off" position Tunnel Drilling Rig picture, stop the main motor fan and drive cabinet fans, but in the main motor running, regardless of the [fan] switch position, the fan will not stop. [Fan] switch toppled the "Auto" position 2015 tunnel drilling rig top drive system starts, automatically start the main motor fan; when the top drive system stops functioning, fan delay stops automatically. Engineering drill include: impact drilling rig, engineering composite drill, rotary well drilling rig. Below we Depending on the application range and characteristics of different projects rig, to provide the basis for the selection of drilling rig. Impact Rig by vertical reciprocating motion drill, drill meat is shock situation, broken rock, simple structure, no circulatory system, debris removal can not be performed with the drilling rig colleagues, therefore less efficiency, drilling depth is generally at 250 meters, sometimes up to 500 to 600 meters. Composite Rig additional impact mechanism on the basis of the turntable on the rotary drilling rig to the main rotary drilling, when faced with the impact of the gravel layer is dual-well drilling rig Rig Tunnel project, the adaptability of various strata strong. Another is to combine the role of impact with the rotary drilling well drilling rig. Rotary well drilling rigs, rotary motion of the drill rely broken rock drilling holes. When the job force by the actuator driving wheel, driven by the initiative of rock broken drill bit rotation.
