Question:

Mixer does not use frequency converter to speed up, then what can be used to speed?

Mixer does not use frequency converter to speed up, then what can be used to speed?

Answer:

Mixer without frequency converter, then you can choose more than two speed motor to speed.1, the best choice of motor speed control is frequency converter. But because of its large one-time investment and maintenance difficulties, small businesses generally use less.2, the motor speed regulation in addition to inverter speed, there are changes in slip speed regulation. But this speed adjustment method is not suitable for mixing machines.3, the motor speed regulation in addition to inverter speed, there are changes in the magnetic pole logarithmic speed regulation. This kind of speed regulation is limited by the pair of poles of the magnetic pole, so it is a kind of speed regulation, which can be done at two speed, three speed and four speed. If the mixer does not need precise speed regulation, it may be possible to adopt the speed regulation method of changing the magnetic pole and logarithmic speed regulation. Practical and easy to repair.4, in addition to inverter motor, and electromagnetic adjustable speed asynchronous motor is also called slip motor, it is a kind of constant torque stepless speed AC motor, because it has a wide range of speed regulation, speed regulation, smooth starting torque, small control power, speed negative feedback, automatic regulation system of mechanical properties for high hardness a series of advantages, and also can be used for mixer.
At present, the best way to speed mixer is to use frequency converter, but in the selection of frequency converter should pay attention to the use of mixer, you are the chemical plant mixer (reactor)? Or engineering mixer? Chemical plants, you should pay attention to the three resistance of the inverter is good, because in the chemical plant water vapor, corrosive gases, it is best to use sealed type inverter. In engineering, the mixer and frequency converter should be enlarged with a power, because the load of the mixer is relatively heavy.
