Vertical Direct-driven Energy-saving Pumping Unit

The vertical direct-driven energy-saving pumping unit (patent number: ZL2005 2 0116972.3) is of tower structure and directly driven by a compound permanent magnet motor supported by a vertical column, which adopts special belt for transmission. It realizes stepless control of stroke and times of the pumping unit through a special frequency conversion control system within a specified range. The gravity balance is obtained by suspension of a weight. The vertical column base is fixed with anchor bolts. Features * Light weight, small covering area, and low investment of supporting equipment. * Suitable for high yield well, low permeability well, deep well, heavy oil well and high gas-oil ratio well. * Quick well round checkout for worker, high anti-wind capability and environment-friendly. * Simplified structure and high reliability. * High efficiency, energy saving, and convenient parameter adjusting. * Perfect operating protection mechanism. * Low maintenance workload, low maintenance cost and convenient displacement during maintenance of the oil well.
