Pumping unit

The sucker rod rope (belt) and counterweight rope (belt) are fixed on the front and rear sides of the drive wheel axle, respectively. When the electric motor moves in a regular forward and reverse direction under the computer control in the electric control cabinet, the drive wheel and guide wheel rotate in the same direction through deceleration transmission, so that the sucker rod and counterweight box move up and down in a reciprocating manner under the drive of the sucker rod rope (belt) and counterweight rope (belt), and drive the oil pump to pump.

Working principle of electronic control

The logic control uses PLC as the processing core, and sets the given signal and the speed of up and down through the operation panel. The travel switch feedbacks the position signal of the counterweight operation, and the PLC determines whether the motor is reversing or offsetting; The constant temperature device provides feedback on the temperature inside the electrical cabinet and determines whether to perform heating or cooling operations through PLC processing. The system has three working modes: automatic, manual, and homework, making it easy to operate and adjust parameters.

Model and specifications of Jinweili series pumping units

The non beam long stroke energy-saving pumping unit with multiple patents combines the characteristics of domestic and foreign pumping units, and its design has reached the international advanced level; This machine has the advantages of reasonable structure, stable operation, low noise, short transmission chain, high system efficiency, safety and reliability. It fully utilizes its characteristics of long stroke, slow flushing, high load, and intelligence, as well as perfect process technology. It is suitable for deep pumping of oil wells with large pumps (replacing electric pumps) and small pumps, as well as the extraction of heavy oil and conventional wells.

Main technical features

Save 30% to 50% electricity (due to the small torque arm and precise balance of the counterweight, the power saving is significant).
Improve pump efficiency by 20% (with low stroke loss and high pump filling coefficient)
The stroke length is 1-8 meters, and the online display of stroke data shows good working conditions. The operation is stable and the impact is small, with a low noise of 67dB. The inertia load and dynamic load of the machine, rod, and pump are small, which can reduce the wear of the pumping rod and oil pipe, and extend the maintenance free period of the oil well.
Low maintenance costs and high comprehensive benefits.
There are multiple safety protections: phase loss, overspeed, overload shutdown, and complete measures for load loss protection.
Easy to adjust the stroke and stroke of the text display.
Automatic fault alarm display.
Motor power factor 0.993
Equipped with 485 communication interface to support multi machine centralized control.
