Motor Reversing Intelligent Pumping Unit

  • Beam pumping unit is the most extensively used mechanical equipment in oilfield, but there exist many inherent defects. Such as high energy consumption, low mechanical efficiency, difficult to realize long stroke.
  • Non-beam pumping unit is developed to solve the inherent defects of beam type pumping unit. It has features of high automation, intelligent parameter adjustment, low energy consumption and low noise.

Motor reversing intelligent pumping unit is a mechatronics, high efficiency and energy saving product. No power reversing technology is adopted. Compared with the traditional beam pumping unit, the mechanical efficiency is increased by 40% and the power consumption is reduced by more than 30%. The related products of our company have won the “Excellent energy-saving achievement Award of Shandong Province”.

Product Advantage
The pumping unit is suitable for low production Wells, low permeability Wells, heavy oil Wells, residential Wells and so on. The pumping unit has the following advantages:
1. No reversing impact and obvious energy saving effect
2. Long stroke, low stroke
3. Intelligent parameter adjustment
4. Simple structure, safety and low noise
5. Easy operation and maintenance
Basic Structure
When the pumping unit is working, the motor achieves positive and negative rotation through the control system, and the drum is driven by the reducer and coupling to make sure positive and negative rotation. The rod is moved up and down by winding or releasing the tape through the drum, and the oil is recovered.
