An electric motor is a device that converts electrical energy into mechanical energy. The energy consumption of an electric motor is mainly the electrical energy lost and wasted in the process of converting electrical energy into mechanical energy. It is a problem of energy conversion efficiency of the motor itself in non-standard environments. When the motor is unloaded, it does not make any beneficial contribution to the conversion of mechanical energy. The motor has no efficiency, but the motor is still consuming power! In the actual production process, the efficiency of the motor constantly changes from 0% to 100% of the rated power. It is necessary to rely on technical means to improve the actual use efficiency of energy, save energy through technical means, and enable the motor to achieve economical operation according to different working conditions. state.

I have systematically elaborated on relevant technologies and principles in many previous blog posts and will not go into details here. Let's do an energy-saving investment analysis on our company's energy-saving products: Since the application fields of electric motors are very wide, I only do an energy-saving investment analysis on typical application fields. Other related application fields depend on different working conditions, and the actual results shall prevail.

Investment analysis of economical operation and energy-saving renovation projects of electric motors and their working systems in the field of oilfield pumping units:

For a long time, the motors used on pumping units in oil fields have suffered impactful variable load loads due to the structure of the beam pumping unit itself and the geology of the oil reservoir. In order to make the motor Stable operation ensures safe production. When equipped with a motor, the motor is equipped according to the maximum power required for the extreme work of the pumping unit.Coupled with the impact of the "generator effect of the motor" on the original power under the special working conditions of the oil field, it has seriously damaged the quality of the power supply of the power grid.

This causes a waste of electricity. Therefore, most of the motors used in pumping units are running at light load, and even some operating sections are running at no load. The actual efficiency of the motor only reaches 20%-30%, resulting in a huge waste of energy.
