MotorWhile bringing more convenience to the production and living environment, the research on energy consumption is also a problem that cannot be ignored.Explosion-proof motor is a kind of motor that can be used in flammable and explosive plants and does not generate electric sparks during operation.Explosion-proof motorsMainly used in coal mines, petroleum and natural gas, petrochemical and chemical industries.In addition, it is also widely used in sectors such as textiles, metallurgy, city gas, transportation, grain and oil processing, papermaking, and medicine.Frequency conversion speed motorA general term for motors driven by frequency converters.In fact, the motor designed for the frequency converter is a special frequency conversion motor. The motor can achieve different speeds and torques under the drive of the frequency converter to adapt to the changes in the demand of the load.The motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction.Faced with the continuous increase in the production cost of purchasing mechanical design products, and the gradual increase in energy consumption.The motor staff suggested that choosing energy-saving mechanical product motors or carrying out technical transformation of original motors to save energy is a good choice for Chinese enterprises in order to save resources and costs. Therefore, our country needs to give the following suggestions:
(A) Optional high-efficiency and energy-saving motors with motor business priority, taking into account its on-demand performance to save energy.
(XNUMX) Improve the efficiency of the system motor itself. For example, the self-cooling fan of the motor can be changed to a cooling fan. The cooling fan can be disabled when the impact of different loads is small or the outdoor motor is in winter, which is beneficial to enterprises to reduce building energy consumption .
The stator winding is changed to a star-delta-delta hybrid series winding, and the star or delta connection mode is changed according to the load weight to achieve the purpose of high efficiency and energy saving.
Figure 4.Other continuous speed regulation operation modes are adopted.Such as the use of voltage stabilizers, pole-changing motors, electromagnetic coupling speed regulators, frequency conversion speed regulators, etc.
XNUMX. Install low-voltage capacitors in parallel with reactive power compensation, effectively improve power factor, reduce reactive power loss, and save energy.
