Precautions

If the equipment is in a humid environment, it is necessary to thicken the anti-corrosion layer of the frame and motor; regularly check the rotation state of the plastic fan, and check the vibration in time if abnormal noise is found; if the equipment is in an open environment, the equipment awning.

Applicable

Plastic centrifugal fans are used for a series of industrial waste gas treatment and ventilation such as chemical industry, electroplating, laboratory, paint, etc. In daily use, proper protection and protection should be carried out, which is an important guarantee for the safe and reliable operation of the fan and the improvement of the service life of the fan. Therefore, when using a fan, full attention must be paid to the exhaust of corrosive acid and alkali gases in industrial plants; the exhaust of different types of gases in chemical laboratory equipment; the ventilation of biological laboratories; the exhaust of deodorization and purification equipment; coastal areas Easily damp and corroded exhaust.

Causes of noise during operation of plastic fan

1. Noise generated by resonance with the air duct shell
The inner joint between the air duct and the fan shell shall be smooth to avoid roughness and unevenness, which may cause tearing sound. The inner joint between the air duct and the fan shell shall be smooth to avoid roughness and unevenness, which may cause tearing sound. Due to the continuous pipe will produce resonance, so that subtle sound louder, resulting in greater noise. Due to the continuous pipe will produce resonance, so that subtle sound louder, resulting in greater noise. In the design, sometimes the sound-proof material can be covered outside the air duct to reduce noise.

2. Noise generated by blade rotation
When the blade rotates, it will rub or impact with the air. When the blade rotates, it will rub or impact with the air. The faster the speed, the higher the frequency of air contact and the sharper the noise. The faster the speed, the higher the frequency of air contact and the sharper the noise. This phenomenon is more pronounced as the width or thickness of the blade increases. This phenomenon is more pronounced as the width or thickness of the blade increases. The noise frequency consists of a variety of frequencies, which are related to the speed of the fan.
