Net airflow and main features of air shower fan

- Apr 03, 2018-

In the process of production, the air shower fan is a very important component in the air shower room. The entire equipment will have an idea prompt system in the process of use. When the air shower is running, The automatic voice system prompts the user to complete the entire showering and dust removal process in an orderly manner. The humanized voice prompt gives a kind feeling and achieves an effective purification effect.

The net air flow of the air shower fan unit after passing through its high-efficiency filter to a certain extent is mainly caused by the rotating nozzle effectively spraying the person's body in all directions, so that the dust particles can be effectively and quickly removed, After efficient filtration, it is blown into the air shower area.

Main features of air shower fan

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

2. The maximum temperature of the air shower fan motor running at the outer surface, the temperature of the motor of its equipment is too high, to a certain extent will first make the magnetic material of the motor demagnetized, which will cause its torque to drop to a certain extent. Out of step, so the maximum temperature allowed by the appearance of the motor should depend on the demagnetization point of different motor magnetic materials; generally speaking, the demagnetization point of the magnetic material is above 130 degrees Celsius, and some even up to 200 degrees Celsius, so the stepper motor The appearance temperature is completely normal at 80-90 degrees Celsius.

The torque of the stepper motor of the air shower fan will decrease with the increase of the rotation speed during the operation of the stepper motor. When the motor rotates, the inductance of each phase winding of the motor will form a back electromotive force; the higher the frequency, the higher the frequency. The greater the counter electromotive force. Under its effect, the phase current of the motor decreases with increasing frequency (or speed), resulting in a decrease in torque.
