Shenyang ventilation pipeline Sometimes noise is found during operation, which is actually normal. But if the noise is too high, manual intervention is required to see what is wrong, or to add some manual solutions to the noise.
Causes of noise in stainless steel air duct
As the stainless steel air duct is made of galvanized steel plate or metal materials, the thickness and construction technology of stainless steel shall be selected in strict accordance with the engineering construction acceptance standards, such as manufacturing error, perpendicularity, structural reinforcement of stainless steel air duct, selection of seismic support and manufacturing equipment. When it comes to project construction, the tuyere shall not be close to mechanical equipment as much as possible. The length of the front, rear, left and right sides of the cooling fan shall be more than 5m as far as possible. If the number of elbows can be increased, the noise can be reduced. The filter screen is modified at the air outlet, so the actual effect of noise control is also very good.
Solution to noise of stainless steel air duct
Noise of centrifugal fan. The solution is generally to install a silencer to solve the contradictory sound of mid stroke in the stainless steel air duct. Generally speaking, noise should be considered in the design. The design scheme controls the wind speed level in the pipeline and how to avoid noise.
1. Control the interval between air inlet and air supply outlet to avoid air convection of small circulation system and self-excited phenomenon in indoor space.
2. The rotor dynamic balance correction of stainless steel air duct centrifugal impeller management system is effective. Normal positive and negative fluctuations shall not exceed 5 lines.
3. Standardized soft joint equipment avoids wind resistance and interior noise caused by slack white canvas of soft joint.
4. The suspension adopts radio frequency connector, which can absorb the yellow impact, so as to alleviate the vibration or common frequency caused by torque during operation.
5. Stainless steel shall be used as far as possible at the corner of stainless steel air duct.
