The use of industrial equipment such as variable frequency speed control technology for speed control has been widely used

The advantage of frequency conversion speed regulation technology for fan pump speed regulation is to use the frequency conversion technology to adjust the fan pump speed to eliminate the starting impact, realize the soft start and soft stop of the motor, so that the motor can run smoothly and reduce the bearing. Mechanical wear reduces equipment maintenance costs. It can be seen from n=60f(1―S)/p that the speed of the motor is proportional to the input power frequency of the motor, so the use of the inverter can realize any adjustment of the motor speed, and it belongs to smooth stepless speed regulation. The traditional method can make the equipment run stably and save energy.

The frequency converter also regulates the fan, and also has the functions of phase loss protection and short circuit protection phase-to-phase short circuit protection. The variable frequency speed control technology can maintain a high power factor while meeting the requirements of the production process, which helps to improve the working efficiency of the equipment. Conclusion At present, the use of variable frequency speed control technology for the speed control of industrial equipment such as fans and pumps has been widely used. It has been proved that this method has a good power saving effect and is a good speed control scheme. However, in the selection process of the inverter, pay special attention to the capacity of the inverter, and select the appropriate capacity according to the actual situation to further reduce the energy consumption. Although this kind of speed regulation scheme is relatively large in the early stage, after running for a period of time, it can rely on energy saving to recover the upfront expenses. It is a speed regulation scheme that is worthy of promotion.
