Downward barbell modified pumping unit

Date: 31 Aug 2009

Downward barbell modified of conventional pumping unit is a new and practical patent technology .It adds on a set of energy saving device in useful space between cross beam、connecting rod、reducer and bracket according to the structure feature of conventional beam pumping unit and  energy saving principle of downward barbell pumping unit. When running, the device core running track is a section of circular arc .When core is over the horizontal line of beam turning center, its gravitational torque is the biggest; when core is close to vertical line of beam turning center, its gravitational is the smallest. According to the principle, masterly producing balanced compound function with crank, meeting torque changing requirement during pumping course for pumping unit and reducing peak torque.
Downward barbell pumping unit we research and manufacture has applied to Shengli oilfield,Huabei Oilfield,Liaohe Oilfield, Sichuan Oilfield, and achieved good market effect, electricity saving rate is over 20%.It is a preferred modified type in energy saving ,increasing output and lower cost of production of old oilfield .
