This oil puming unit is the updaged advanced type for replacing the traditional four-bar travel beam pumping unit.

Oil field pumping unit description

A breakthrough of the design and operation modes applied by all existing oil pumps, the DLS series oil pumps rely on motor ALA rotors to transmit low-speed high torque through means of friction, ideal balance effect, axle effect and free pulley effect to neutralize the drive load of the motor and an intelligence control system to convert the forward-reserve rotation of the motor into the vertical reciprocation of the sucker rod. Besides, the DLS series can, in a timely manner, adjust the motors rotation speed, direction and torque according to supply to the oil well to offer the best stroke and stroke frequency conjunction that is dynamically coordinated with formation supply capability, and realize a suction cycle that's energy-efficient and intelligent.

The unique technologies for making the flagship of oil pumping machines

1. Special motor integrating five functions and one axle has the prime mover driving, commutation, speed varying, balancing, load shedding, unload protection, brake, suspension shaft, metering, and power measuring;

2. Multi-stage load shedding device may reduce the motor driving load to 5-6% the maximum load of hanging point;

3. Anti-fall emergency brake and non-isometric brake linkage may realize the suspension shaft and unload protection;

4. Twin-set gear short magnetic path or minor coincidental gear switch magnetic resistance motor may realize 150% rated torque with 30% rated current,cosφ≥0.95;

5. Instantant gravity difference “0” current commutation broken through the traditional concept of motor high starting current, realized the optimum matching;

6. Instantant resulting torque SRM adaptive control technology effectively suppresses the fluctuation of torque;

7. Pumping parameters and formation fluid supply ability dynamic coordination realized the optimum matching of power consumption;

8. Special anti-theft lock keep the robbers away.

The advanced technical advantages enjoy the leading position home and abroad

1. Energy saving and consumption reduction: compared with the traditional four-bar travel-beam pumping unit, it can save the energy 20-60%, and save the materials 10-60%;

2. Low carbon, environment protection: compared with traditional four-bar travel-beam pumping unit, it can reduce the carbon emission 50%, with noise lower than that of standard of noise at boundary of industrial enterprises, and zero emission of whole machine;

3. High safety and high reliability: the hardware itself elimites the unsafe factors, low speed running, high safety and reliability;
