Here and we come to understand how to effectively reduce the noise on the duct products.
        In the noise control requirements of high occasions, should use low noise Kunshan ventilation pipe equipment. Different  types of ventilation duct equipment in the same air volume, wind  pressure, the wing type of centrifugal ventilation equipment, small  noise, forward version of the type of centrifugal ventilation equipment,  large noise. Appropriate to reduce the speed of Suzhou ventilation pipe equipment. Ventilation  pipe equipment, the rotation noise and impeller peripheral speed 10  times the proportion of eddy current noise and impeller peripheral speed  6 times the proportion, to help reduce the speed can reduce noise.
        In the design of ventilation duct system, should try to reduce the system pressure loss. When the total amount of Suzhou ventilation duct system and the pressure loss is large, it can be divided into small systems. Air flow in the ventilation duct flow rate should not be too high, so as not to cause regeneration noise. Determine  the air flow rate in the ventilation duct should be selected according  to different requirements according to different requirements.
