Pumping Unit

This kind of pumping unit is with modern 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 oil well and heavy oil well. 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 efficiency, reliance and energy-saving. At the present, our belt pumping units have been exported to Indonesia, 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 equipment consumption small and operation cost small. 2. Adjustable workover location and easy for workover. 3. Belt transmission. It adopts long life, high strength 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 optimize 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 requirements and realize mixed braking purpose and more safe. The whole set adopts closed design, foldable transportation which is safe and convenient. 7. No need frequent maintenance. It adopts wore bearing, long life belt and heavy duty chain which ensure the reliability 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 requirements. Automatically control stroke times and automatically recover oil which makes the unmanned on duty be reality.
