Crude oil is known as "black gold", and the pumping unit is an important equipment for oil field mining. It requires a lot of energy consumption in its production process，Energy conservation and emission reduction, cost reduction and efficiency improvement, and promoting the localization of major petrochemical technical equipment have become issues that today's oilfield companies must pay attention to when seeking further development. The direct-drive screw pump solutions, beam pumping unit solutions, and winch pumping unit solutions launched by Sine Electric help petrochemical companies reduce costs and increase efficiency.

The direct drive screw pump solution is a commonly used oil production equipment in oil fields. It consists of a mechanical transmission system and an electrical control system. It cancels the traditional belt drive, reduction box reduction device, shutdown anti-reverse mechanical device, etc., and adopts a low-speed permanent The magnetic synchronous motor directly drives the polished rod to drive the underground screw pump

Automatically releases torque when stopping:When stopping, it can automatically detect the screw reverse acquisition value. Allow its reaction torque to be released slowly and under control, even during abnormal stops, including sudden power outages. The torque can also be reduced to ‘0’ and the energy can be released safely. Avoid screw damage. Ensure production safety

Torque protection function:real-time automatic protection when exceeding the set value

Automatic well cleaning mode:automatically adjusts the pumping speed when detecting well cleaning operations.

The direct-drive screw pump solution launched by Sine Electric can not only meet the requirements for smooth operation of the equipment, but also directly drives the polished rod through the motor, with a transmission efficiency of up to 98%. It can also effectively improve the working efficiency of the oil pumping equipment and achieve maximum energy saving.

The beam pumping unit solution can improve equipment operation efficiency. Extend the service life of equipment and save energy. Improve the working conditions of the sucker rod. Reduce the number of breaks.

The intermittent pumping function:enables intermittent oil production, saving energy and increasing efficiency.

Speed-dividing function:automatically switches speed during the remaining stroke to increase production capacity.

Flexible control: Adjusting the motor speed in real time according to the load size can reduce the impact intensity of the transmission gear. and the impact of load fluctuations on the power source. Reduce the average power of the system.

Adaptive energy saving: During the operation of the driving motor, the required electric energy is calculated in real time, and then the corresponding speed, voltage and other parameters are adjusted. Minimize energy consumption.

Stroke setting:set different stroke times and automatically calculate the corresponding operating frequency.

Winch pumping unit solution, Significantly improve the efficiency of the oil extraction system of the pumping unit. Save energy and reduce mining costs. Realize effective development of oil field resources. The motor is equipped with a reducer to drive the drum, which retracts and unwinds the 70-meter-long steel rope, so that the oil pump can go up and down at a depth of 50 meters, and the operating oil well depth can reach 2,000-3,000 meters. During the upward movement of the oil well, the machine is always in the pumping state; during the downward movement, the motor is in light load operation.

Anti-fall function: Full closed-loop control of the special frequency converter for the sine electric oil pumping unit. When the equipment brake fails, the hoisting rope drum will not be able to brake, causing the pumping rod to slide. At this time, the zero servo function is started by controlling the motor through the frequency converter, using Electric braking torque ensures that the sucker rod and cable do not fall.

Brake control logic: Automatically realizes the brake control function. The reversal is not closed during normal operation. It can lock the motor through mechanical braking during shutdown and open during operation.

Overspeed protection: through real-time detection of the difference between the given speed and the feedback speed, ensures that the difference is within a certain range.Avoid equipment damage caused by abnormal speed.
