FULLY AUTOMATED DEVICE FOR OIL EXTRACTION Russian patent published in 2005 - IPC

FIELD: oil and gas extractive industry.

SUBSTANCE: device has axial transmission and soft stripe support system. Axis connects electric engine to reducer and connected reducer and leading hub, by means of which transmission lines are actuated. After connection of driven hub and device for supporting pump bars, pump bar for actuating well oil pump can be connected. Leading hub can actuate transmission lines, including one connected to balancer, operating synchronously to operation of well oil pump in both directions. Also, device has base, corbel and platform, controller for controlling oil extraction process, transformer, frequency setting transformer, absolute values encoding means and braking tank. Said electric engine, reducer and leading and driven hubs are mounted on the platform. Controller, through setting frequency generator, functioning as main drive, is connected to electric engine. Controller is connected to encoding absolute values means, capable of displaying working conditions and receiving data about position and rotation angle of leading hub. Encoding means for absolute values and braking block compose a portion of device for determining movement and braking. Controller can contain central processing module, input/output module and liquid-crystal display. Controller can be connected to encoding extension means, immediately receiving data about angle, position and rotation speed of electric engine axis.

EFFECT: higher efficiency.
