Characteristics of air shower fan and blowing dust removal process

- Jul 19, 2018-

The air shower fan is an important component of the air shower room to a certain extent. The whole device will have an idea reminder system. When the person is blowing, the automatic voice system prompts people to complete the entire dusting and dust removal process in an orderly manner. The voice prompt gives a kind of intimate feeling and achieves an effective purifying effect. The clean air flow filtered by the high-efficiency filter is sprayed from all directions to the person by the rotating nozzle, effectively and quickly removes the dust particles, and the air is filtered by the initial and high efficiency. After blowing into the air shower area.

Air shower fan features

1. The accuracy of the general air shower stepper motor is 3-5% of the step angle and does not accumulate.

2. The maximum temperature allowed by the motor surface of the air shower fan. If the temperature of the stepping motor of the air shower is too high, the magnetic material of the motor will be demagnetized first, which will directly cause the torque to drop to the out of step, so the maximum temperature allowed by the motor appearance It should be determined by the demagnetization point of the magnetic material of different motors; in general, the demagnetization point of the magnetic material is above 130 degrees Celsius, and some even up to 200 degrees Celsius, so the external temperature of the stepper motor is completely normal at 80-90 degrees Celsius. .

3. The torque of the air shower stepper motor will decrease as the speed increases. When the stepper motor rotates, the inductance of each phase winding of the motor will form a back electromotive force; the higher the frequency, the larger the back electromotive force. Under its action, the motor decreases with increasing frequency (or speed), resulting in a drop in torque.
