Double-horsehead Pumping Unit

Double-horsehead pumping unit is an energy saving product that has a long stroke and low SPM. It is used for pumping oil of middle and high viscosity and high water content.

doublehorse

In addition to the common advantages of conventional beam pumping unit, the unit has advantages of long in stroke length, small in dynamic loads and variation of the torque, high in ef- ficiency, low in energy consumption, smooth in operation and easy in start, etc. A multi-purpose electric cabinet is incorporated in the unit, which has the functions of short circuit protection, overload or underload protection, offset without work, automatic start after power resuming, over speed control of the motor, etc. It is made of the materials cut by numerically controlled flame cutting machines to ensure accuracy and surface quality.

As compared with the same model of the conventional pumping unit, it increases the stroke length by about 70%, reduces energy consumption by 20-30% and decreases unit installed capacity by about 50%.
The unit is new in structure and evident in energy saving. It was taken as a stressed spreading project by CNPC in 1994 and a nationally stressed spreading project in 1995.

Compound balanced pumping unit

The 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.

compound

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 equipments. In- tegrating all advantages of the common walking beam pumping unit, it has reliable performance, simple structure and can be conveniently op- erated and repaired.

Motor Reversing Pumping Unit

Motor reversing pumping unit is a high efficiency and low energy consumption product.

motor

It employs the intel- ligent and digital control and uses the switched re- luctance motor as the prime mover which the power factor is cos??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 efficien- cy reaches to 50%, and energy saving rate is about 46%. The product is an ideal pumping unit to replace conventional beam pumping unit.

Reactive commutation intelligent pumping unit

The reactive commutation intelligent pumping unit is an integrated mechanical and electrical product with high performance and energy-saving function.

reactive

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 equipments. In- tegrating all advantages of the common walking beam pumping unit, it has reliable performance, simple structure and can be conveniently op- erated and repaired.It adopts the non-energy consumption commutation technology, which can improve the mechanical efficiency by about 40% compared with the com- mon 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.
