The use of Flextronics inverters in the reactor kettle mixer
First, the configuration and operation of the mixer:
In chemical, pharmaceutical and other industries, the application of reaction vessels is quite common. Most of the mixing process before the use of mechanical or slip speed, the use of continuous exposure to stepless speed regulation, the media is not sensitive to different speed, low-speed torque is not enough and many other shortcomings, is now changing to use VEICH-AC32 universal inverter problem Dissolve it and greatly improve work efficiency and save energy.
Mixing machinery in the design according to the use of conditions are considered a certain margin, and in the actual use of the process, due to the difference in production, the medium does not have to work under the maximum load, there are many hours can work in the non-full load state Traditional mixers usually do not adjust or use mechanical speed control, can not meet the timeliness and accuracy of the speed control process; slip speed control sometimes at low speed, the material viscosity is large and can not stabilize the speed; This shows that the traditional speed-regulating method will not only increase the loss of the mixer's own machinery, but also make the mixing equipment work in the “big horse-drawn car†state, which is not economical.
The energy-saving effect of the speed control method of the frequency converter has now been recognized by more and more customers, and it is better than any of the previous speed-regulating methods. Therefore, by installing frequency conversion speed-regulating energy-saving devices on the mixer equipment, it can be solved once and for all. There are many problems in the process of using the traditional mixer, and the investment can be recovered through frequency conversion and energy saving.
Second, mixer frequency conversion program:
According to the characteristics of the mixer configuration and the large operating torque, a general-purpose inverter speed-regulating device is usually installed on the mixer; the original industrial frequency system of the mixer is reserved, and the frequency conversion system of the mixer is used as a standby for mutual switching. , Interlocking between power frequency and frequency conversion.
Third, the function and advantages of mixer frequency control device:
1, the mixer frequency conversion energy-saving device for the open-loop regulation;
2. The soft start function of the inverter can greatly reduce the starting impulse current;
3. Inverter has intelligent protection, automatically stop and record when fault occurs;
4, according to different processes, different materials in a timely manner given different speed, improve product quality;
5. Energy saving and consumption reduction through frequency conversion speed regulation:
