Product features:

· Product design and manufacture implement API SPEC 11E specification and China petroleum industry standard CB/T29021, through API and industry certification.

· Based on the structure of the four-bar beam pumping unit, design an automatic balancing device to install on the tail beam pump.

· Achieve the automatic and real-time adjustment of the pumping unit balance, so that the balance of the pumping unit is always in the set balance range.

· Achieve the automatic and real-time stroke frequency adjusting of the pumping unit, artificial adjustment on the well site and so on, so that the pumping unit is always in the best working condition. 

· Achieve the automatic collection and transmission of electrical parameter (voltage, electric current, power factor, active power, reactive power and so on) of the pumping unit.

· Achieve the automatic collection and transmission of well head parameter (casting pressure, oil temperature, oil quantity and so on) of the pumping unit.

· Achieve the automatic collection and transmission of operational parameter (stroke, stroke frequency, degree balance and so on) of the pumping unit.

· With remote control fuction of stroke frequency, balance, start and stop.

· The balance of adjustment device runs smoothly, high safety and has a large balance adjustment range.

· The installation and maintenance are basically the same as that of the conventional beam pumping unit, the · pumping unit using the design concept of modularization, high universalizable.

· This pumping unit is a new type of pumping unit with independent intellectual property rights, systematic and intelligent characteristics.
