Motor Reversing Pumping Unit

Categories:Pumping Unit

Brand:SJ

API 11E:high efficiency

Motor reversing pumping unit is a high efficiency and low energy consumption product. It employs the intelligent analog and digital control and uses the switched reluctance motor as the prime mover, of which the power factor is cosΦ≈1. As the transmission of the friction wheel is the working mechanism, the mechanical transmission line is short and the efficiency is high, realizing the reversion of the motor. The starting reversion is stable with low impact. The stroke and stroke frequency can be regulated independently and steplessly. The velocity of the up stroke and down stroke of the polished rod can be controlled respectively.

Its mechanical efficiency is about two times that of conventional beam pumping unit. Its system efficiency reaches to 50%, and energy saving rate is about 46%. The product is an ideal pumping unit to replace conventional beam pumping unit.  

The motor reversing intelligent pumping unit is a mechatronic product of high efficiency and energy-saving. It has a tower-like structure, characterized by steady start-up, highly efficient and energy-saving, intelligent control, safe and convenient, and remote monitoring.

Reactive Commutation Intelligent Pumping Unit

Categories:Pumping Unit

Brand:SJ

API 11E:high performance

Reactive commutation intelligent pumping unit is an integrated mechanical and electrical product with high performance and energy saving function. It adopts the non-energy consumption commutation technology, which can improve the mechanical efficiency by about 40% compared with the common walking beam pumping unit and save energy consumption by above 30%. Using intelligent simulation and digital mixed control, it can adjust oil pumping strokes according to the load condition to get economical and reasonable matching to various oil wells' operational parameters. Therefore, it has good adaptability. Adopting balanced opposed mode, it has precise balance. The pumping unit runs stably with small noise. It can actualize stepless parameter adjustment with easy and simple operation. It can also realize remote control.

Reactive Commutation Intelligent Pumping Unit applies zero energy consumption technique and realizes high efficiency and energy-saving. It can be automatically regulated based on the well performance, running stably and easy to operate. It can also be remotely monitored and managed.

Compound Balanced Pumping Unit

Categories:Pumping Unit

Brand:SJ

API 11E:reliable performance

Simple Structure:easy to install and maintain

Compound balanced pumping unit is added with the lower barbell rigid device on the base of the common walking beam pumping unit to make the reducer's torsion change slowly. This has not only achieved the energy saving effect through reducing the peak torsion, but also greatly improved the working condition of the pumping unit, increased the working capacity and prolonged the working life of equipment. Integrating all advantages of common walking beam pumping unit, it has reliable performance,  simple structure and can be conveniently operated and repaired.

The special design of compound balanced pumping unit saves energy by reducing peak value torque, greatly improves the working conditions of the unit speed reducer, increases the working capacity and extends the working life of the equipment. It is of high reliability, simple structure and is easy to operate and repair.

Beam Pumping Unit
