What power-saving measures does the factory have? Will the 5.5kw motor save electricity if it is replaced by a 7.5kw motor?

1, update and eliminate inefficient motors and high-power equipment: promote high-efficiency and energy-saving motors, rare earth permanent magnet motors, high-efficiency fans, pumps, compressors, high-efficiency transmission systems, etc. Update and eliminate inefficient motors and high-power equipment; Adopt high-efficiency energy-saving motor and system-related energy-saving equipment, and newly install motor system. Gradually restrict and prohibit the production, sale and use of backward and inefficient products. The transformation of old equipment focuses on the transformation of small and medium-sized motors, fans and pumps with high power consumption and the reasonable matching of constant current systems.

2. Improve the efficiency of motor system: popularize advanced motor speed regulation technologies such as frequency conversion speed regulation and permanent magnet speed regulation, improve the regulation mode of fan and pump motor system, and gradually eliminate mechanical throttle regulation modes such as gates and valves. Focus on the speed regulation reform of large and medium-sized variable working condition motor system, reasonably match the motor system, and put an end to the phenomenon of "big horse-drawn car".

3. Drag device control and equipment transformation: the advanced power electronics technology transforms the traditional mechanical transmission mode, and gradually adopts AC speed regulation instead of DC speed regulation. Using high-tech to transform the drag device, the demonstration transformation of large-scale water conservancy irrigation and drainage equipment and large enterprises with a total motor capacity of 65438+100000 kilowatts was emphasized.

4. Optimize the operation and control of motor system: popularize soft start device, reactive power compensation device and computer automatic control system. Through process control, the energy can be distributed reasonably, and the economic operation of the system can be realized.
