Are you still confused about choosing a blender? Next today, I want to introduce the ingredients of the blender. I hope it will help you when you choose.
一、Speed control mode
Ac frequency conversion speed regulation, the speed is affected by the load small, the motor is high, low temperature rise, long life, suitable for high power. Ac and dc speed control, the speed is not affected by the load, the motor is less efficient, the temperature rise is slightly higher, the long life, only applicable to small power. The speed is affected by the negative band, not constant, the motor is medium, life is limited by brush.
二、Power, speed and torque
The relationship between the power, speed and torque of the mixer is the following：
The motor rated torque is proportional to the motor power and inversely proportional to the rated rotating speed. The most caring thing about the application is "select the power", generally speaking, the power selection is a little larger than the other. Power enough, eventually the motor temperature rise (delta T 45 ℃ or less normal).
Because all of the electronic speed is usually constant torque speed, when low speed power loss is very big, so for high viscosity materials mixing usually should be chosen with mechanical reduction of low speed high torque mixer.
三、Stir bar
The length of the whip should be as short as possible, and the container should be supported to reduce stirring.
