Submersible pump with permanent magnet motor

Our company's submersible pump system uses a high-speed permanent magnet motor to replace the traditional three-phase squirrel cage asynchronous motor. The motor can be arbitrarily adjusted from 0 to 3600 rpm, which is highly efficient and energy-saving. The motor efficiency is more than 92% and supports a full torque start, up to 1.5 times.

System advantage

1. Large displacement oil recovery (50-1000m3/d);

2. Head high (up to 3000 m);

3. No eccentric wear of sucker rod and pipe, especially suitable for mining of inclined wells and horizontal wells;

4. Oil well monitoring system, real-time monitoring of oil production dynamics.

Advantages of the permanent magnet motor

1. High-speed, high-efficiency, energy-saving permanent magnet motor, compared with traditional equipment, generally saves energy by more than 30%;

2. It can be driven by any frequency converter and supports voltage-frequency ratio control mode;

3. The permanent magnet motor is only half the length of the traditional motor, which improves trafficability.

4. The calorific value is lower than that of ordinary motors by more than 10 °C, the aging speed is reduced by one time, and the service life is long;

5. High temperature resistant materials are selected, and the rated temperature resistance of the whole machine is 204 °C;

6. Low no-load current, less than 10% of nameplate current;

7. Power factor ≥ 92%, efficiency ≥ 92%.

Specifications

Bomb for well rod

Once the rod pump is assembled in the ground, it is attached to the bottom end of the sucker rod and everything is lowered into the well through tubing. There is no need to raise and lower the oil pipe when overhauling the pump, which is convenient for operation and suitable for deep wells. Since the working time is shortened and the number of times the oil pipe is turned on and off is reduced, the service life of the oil pipe is prolonged. Rod well pumpscan be divided into mechanical type and cup type according to the type of support mounting, and can be divided into three types: fixed upper fixed cylinder, fixed lower fixed cylinder and fixed lower movable cylinder according to the support position. .

Tube well pump

The working process of the tubular oil well pump is: the pump barrel is lowered to a predetermined depth together with the oil pipe, and the plunger is connected with the sucker rod and lowered into the pump barrel . In the case of the same pipe size, a larger pipe pump can be installed than a rod pump. The tube pump has a simple structure and is suitable for oil wells with shallow pumping depth and high output.
