The so-called tungsten alloy air curtain counterweight refers to the tungsten alloy balance weights which can calibrate the dynamic balance of the air curtain’s wind wheel, it also called balanced folder. Whether it is an air curtain or some other rotating mechanical parts such as the balance wheel of watches and clocks, internal combustion engine crankshafts, auto wheel hubs, propellers of aircraft, etc., the dynamic balance of them all need to be calibrated so that can guarantee the stability when they work.
The effect of tungsten alloy counterweights is to calibrate the wind wheel of air curtain, thus can reduce the vibration and noise which is generated due to the worse dynamic balance under the high-speed operation process. For the air curtains that used in the major shopping malls, these vibrations will not only do great effects on the overall performance of the air curtain, for example it will have little capability to prevent the outdoor heat, mosquitoes, dust, etc. in summer, but also produce lots of noises which will disturb the guests who are coming and going through the air curtains. Therefore, using tungsten alloy counterweights to balance the moment of inertia of the wind wheel, so that can maintain a stable rate of rotation in the case of high-speed operation, in order to reduce the vibration generated by wind curtains thus to reduce the noises. Finally, it can ensure the overall performance of air curtain, and extend its service life. So it can be seen that a small piece of tungsten alloy counterweight, can play an important and immeasurable role in some fields.
