Belt Pumping Unit

GJ wide-belt pumping unit is a new type of mechnical transmission chain-belt pumping unit, which is substructure optimized, performance improved by our company on the basis of the traditional chain-type pumping unit. This kind of pumping unit is with morden design and a compact substructure, convenient to be fixed and used, and it also have a good operating performance, low energy consumption, long stroke and low frequency of stroke, especially can be used in the recovery of deep oilwell and heavy oilwell. This series pumping unit has advanced technology at international markets and earned good economical and social profits for customers home and abroad by its high efficency, reliance and energysaving. At the present, our belt pumping units have been exported toIndonisia, middle-east and some other countries.The main advantages: 1.Long stroke, low frequency of stroke, low cost. Long stroke make pump factor high and pressure surge small; low frequency of stroke make downhole equiment comsumption small and operation cost small. 2.Adjustable workover location and easy for workover. 3.Belt transmission. It adopts long life, high srength and heavy duty belt for power transmission. Its elasticity reduce surge of direction changing, which makes pumping string operate smoothly. 4.Automatic relocation device. Adopt automatic relocation device with humanity design, which can reduce labor input and make the workover operation more convenient. 5.Adopts limited element analysis to make parts optimise analysis, the rigid of whole unit become smaller which makes operation reliable and stable. 6.Reliable braking device and can be equipped with electrical braking device based on customers requirments and realize mixed braking purpose and more safe. The whole set adopts closed design, foldable transportation which is safe and convenient. 7.Don't need frequent maintenance. It adopts wore bearing, long life belt and heavy duty chain which ensure the reliablity of the whole set. 8.Mechanical balance and complete lubricant system, automatic protect device and whole set enclosed, which makes the equipment extending maintenance period and raising oil output. 9.Automatic control for whole set can be realized based on customer requirments. Automatically control stroke times and automatically recover oil which makes the unmanned on duty be reality.Type/parameter GJ.1100 GJ.1000 GJ.900 GJ.800 GJ.700 GJ.600 GJ.500 Stroke Length 8 8 7.3 7.0 6.0 5.0 4.5 Peak Polished RoLoad 22 20 16.3 14 12 10 8 Max of StrokesPer Minute 4 4 4 4 4 5 5 Min of Strokes Per inute Very Low Counterweight Base 6.1 4.6 4.2 2.7 2.4 1.9 1.7 Counterweight-Max Aux. 9.5 9.0 7.2 7.1 6.4 4.8 3.5 Shipping Weight 28 22 19.5 16.5 15.5 12.0 11.0 External Size(L×W×H) 7.4×2.6 ×12.8 7.4×2.4 ×12.8 6.6×2.4 ×12.4 6.1×2.1 ×11.8 5.5×2.1 ×10.8 5.5×1.9 ×8.9 5.2×1.9 ×8.2 Shipping Size(L×W×H) 12.8×2.6 ×3.1 12.8×2.4 ×2.8 12.4×2.4 ×2.8 11.8×2.1 ×2.6 10.8×2.1 ×2.5 8.9×1.9 ×2.5 8.2×1.9 ×2.5 Motor power 55 55 45 45 37 37 37 Torque of Gearbox 53 53 37 37 26 26 26 Working Temperature -40 50 Note: Automatic Braking System is available according to the customers requirements.
