Analysis of Characteristics of Variable Frequency Control Cabinet

1. Save energy

Compared with traditional control motors, energy conservation is the most practical significance for frequency converter controlled motors. The motor operating conditions supplied according to the demand for water injection and oil transportation are economical, which can save 48.8% of electricity

2. Reduced operating costs

The operating cost of traditional motors consists of three components: initial procurement cost, maintenance cost, and energy cost. The energy cost accounts for approximately 77% of the operating cost of the motor. By reducing energy costs by 44.3% and minimizing the impact of variable frequency starting on equipment, maintenance and repair costs will also decrease, resulting in a significant reduction in operating costs.

3. Improve pressure control accuracy

The variable frequency control system has precise pressure control capability. Match the pressure output of the motor with the required water injection amount of the system. The output of the variable frequency control motor changes with the change of motor speed. Due to the improved accuracy of variable frequency control of motor speed, it can keep the system pressure variation of the pipeline network within a range of 3pisg, that is, within a range of 0.2bar, effectively improving the quality of working conditions.

4. Extend the service life of the motor

The frequency converter starts the motor from 0HZ, and its starting acceleration time can be adjusted to reduce the impact on the electrical and mechanical components of the motor during starting, enhance the reliability of the system, and extend the service life of the motor. In addition, frequency conversion control can reduce current fluctuations during unit start-up, which can affect the electricity consumption of the power grid and other equipment. Frequency converters can effectively minimize the peak value of start-up current.

5. Reduced the noise of the motor

According to the requirements of the motor's operating conditions, after installing variable frequency speed regulation, the motor's operating speed significantly slows down, effectively reducing the noise during motor operation.
