Silent, energy-saving pump unit with electric control reversal

The intelligent rotary motor inverter pumping unit developed by our company is a new generation of oil extraction machinery developed on the basis of summarizing the advantages and disadvantages of traditional pumping units in oilfield applications and combining the advantages of current ROTAFLEX belt pumping unit.

Characteristics

1. Silent and energy saving. The permanent magnet motor with low speed and high torque is selected, which has the advantages of high torque density, strong anti-demagnetization ability, high-efficiency power factor, and strong overload capability. The noise at 1 meter away from the pumping unit is less than 51 dB, and at 10 meters away it is less than 45 dB. The noise of the whole machine reaches the standard of Class I stipulated in the national standard GB3096-2008, especially suitable for oil well drilling near residential areas and business districts;

2. New permanent magnet motor. The motor structure not only retains the characteristics of simple production and reliable use of conventional permanent magnet motors, but also has the advantages of external rotor motors' compact structure, low failure rate, and convenient maintenance;

3. Double brake protection, safe and reliable. The built-in normally closed (9t) brake device of the motor and the external normally closed (12t) hydraulic disc brake device, double brake system, if any accident occurs during operation, the brake system of the pumping unit will be will start immediately, and the whole oil production system will stop working) to protect the whole oil production system from damage;

4. The structure of the whole machine is simple, there are few wearing parts, the maintenance workload is small, and the maintenance cost is low. You only need to check and maintain the pumping unit once a year, which greatly reduces the labor intensity and maintenance cost of workers;

5. According to the working conditions of different oil wells, up and down strokes and stroke times can be adjusted without stopping the machine. Fast operation mode;

6. 90% of the pumping process is smooth movement, and the reversal is smooth acceleration and deceleration, which effectively reduces the shock load on the rod and the pump, and prolongs the inspection cycle of the pump.
