I. Introduction

 

The hot air blower is a kind of air blower. It is mainly used in the automatic mechanical equipment of the hot air drying industry. It is the best hot air source configuration. It is especially suitable for non-flammable and explosive use environments. It can improve energy reuse and greatly save use costs. . People who have been to Xinjiang know that Xinjiang produces a large amount of corn. Almost every family has dozens of acres or even hundreds of acres of land to grow corn, but it is a problem to dry the corn after it is ripe. There are not enough drying plants for everyone to dry. Introduce the application of ED3100 high-performance vector inverter produced by Yiqiu Company in corn drying equipment in a certain area of Xinjiang, which greatly solves this problem.

summary

 

Using the frequency converter to start the fan can realize the soft start of the fan, and the start is smooth and without impact. On the one hand, it can reduce the impact on the wind turbine and the power grid at startup, which not only protects the motor and extends its service life; on the other hand, the frequency conversion speed regulation changes the air volume to achieve the purpose of quickly adjusting the air volume; the most important thing is to save energy and operate at power frequency. Compared with energy saving, it can save about 40%.
