Electro-hydraulic proportional control technology applications in engineering in engineering drill rig production, drilling rig how to automate production control, depending on one gate technology, this technology is how much money Proportional Technology XY-2 type drilling rig electrophoresis proportional technology as an interface engineering of mechanical systems, control engineering rig automated production. Drilling rig used after control technology to achieve a good electro-hydraulic proportional system simplifies production of complex process control, thereby reducing production costs, improve quality control process engineering rig, improve production reliability, shorter drilling rig working cycle time. Electro-hydraulic proportional technology applications engineering drill, is more conducive to automated drilling rig, efficient, intelligent development, but also to improve production efficiency and control performance engineering rig, has an important value, which is electro-hydraulic Proportional technology existence. Rig the main motor heating equipment: top drive power unit heater main motor and the main motor is not running properly, you can heat the motor [] switch, start and stop the heater by PLC / MCC on the door, through the PLC / MCC cabinet heating indicator indicates the operation 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 XY-2 type drilling rig, will directly start the main motor fan. [Fan] switch toppled the "off" position XY-2 type drilling rig video, stop the main motor fan and drive cabinet fans, but in the main motor running, no matter how [fans] switch position, the fan will not stop. [Fan] switch toppled the "Auto" position, the top drive system starts, automatically start the main motor fan; when the top drive system stops functioning, fan delay stops automatically.
