1. Fan
With the continuous development of industry, the application of fans is becoming more and more extensive, especially in the chemical, stone and textile industries. And in the fan design generally has the problem of air volume, when the air volume needs to be adjusted, throttling, that is, the damper adjustment mode, and this is unnecessary loss, after the use of frequency conversion speed regulation, it can be easily adjusted according to the actual needs, due to the removal of unnecessary loss, while improving the power factor, its comprehensive power-saving rate is more than 30%.
2. Speed regulating machinery
In the machinery that needs to regulate the speed, such as: extruder, material feed adjustment, conveyor belt, etc., basically use slip adjustment motor, three-phase commutator motor or DC motor speed regulation, the speed regulation performance of the speed regulation motor is not good, the speed stability is poor, the failure rate is high, and the efficiency is low. However, the structure of DC motor and commutator motor is complex, the failure rate is high, the maintenance cost is high, and sparks will be generated when they work, which is extremely unsafe. The above motor speed regulation stability is poor, such as using asynchronous motor plus frequency conversion governor to replace the above kind of motor, can greatly improve efficiency, power saving, small maintenance, safety, reliability, short return on investment period, to improve the economic benefits of enterprises are extremely beneficial.
Low-pressure inverters are more widely used, such as blowers, conveyors, feeders, mixers, grinders, pulverizers, paper cutters, calenders, extruders, valves, compressors, cooling pedals, plastic machinery, elevators, various textile industries, etc. Large-scale application areas such as paper mills in paper mills, injection molding machines in mold factories, rolling mills in metallurgical plants, and fans, pumps, cranes, oil pipelines in chemical and other industries.
