VFD for industrial agitator
The liquid agitator has a wide application in the manufacturing process of the chemical industry and so on. The industrial agitator will consider having a certain allowance in design according to the requirements of the service condition. When the industrial agitator is in practical operation process, it is not required to always work with the maximum revolving speed. In many circumstances, it can work in not full load status. The traditional industrial agitator usually conducts no regulation or regulates the speed in mechanical method. The speed regulation in mechanical method will increase the loss of the industrial agitator. Meanwhile, the industrial agitator will work in fluctuating status. Furthermore, it will also work in the status of "big rated power with small load power", which is quite not economic. The motor power of the industrial agitator in operating under the frequency conversion speed control is similar to its characteristics of the revolving speed and pump load. Using VFD for speed regulation will obtain a substantial energy saving rate.
II. The advantages of ATO VFD control
- The start-up of the VFD belongs to soft start. It can reduce the impulse current in starting. It has stable start and even agitation. Furthermore, it has intelligent protection, which can reduce the damage to the devices.
- Different revolving speed can be adopted according to different technologies. Meanwhile, it can achieve a good energy saving efficiency.
- Low frequency and big torque. The torque can be regulated automatically to realize the agitation of various raw materials.
- Distinct structural design and independent air duct design enable it to be suitable for the serious occasions with humidity and dust.
