The prevention of vibration and noise during the installation of ventilation pipes is an important link in the installation process. The prevention of vibration and noise of ventilation pipes during the installation process mainly starts from the following aspects. The ventilation pipe processing personnel in Jinan will explain to you.
① During the installation of fans, vibration damping devices shall be set according to the design requirements or construction specifications.
② The fan and the ventilation pipe are connected by hoses. The hoses at the suction inlet of the fan shall be installed with proper tightness to avoid noise and vibration caused by the loose soft connection which reduces the area of the air inlet and outlet.
③ The ventilation pipe shall be manufactured, installed and connected with components in a tight manner without air leakage to avoid air leakage noise. Prevention of vibration and noise during installation of ventilation pipe
④ In order to prevent the vibration of the ventilation duct, fixed supports shall be set at the turning of the ventilation duct of each system and the connection with the ventilator and the air outlet.
Air leakage test of the ventilation duct after the installation of the ventilation duct, the air leakage test shall be conducted. According to the specification, the air leakage test of the ventilation duct adopts the method of combining the legal and quantitative detection of the light leakage. The light leakage method is suitable for the tightness test of the medium and low pressure systems; Air leakage test is suitable for sampling inspection of medium pressure system and full inspection of high pressure system. Light leakage detection of ventilation duct light leakage detection is a method to qualitatively detect the tightness of the ventilation duct of the system by using the strong penetrating vision of the light to the small hole.
The key points that cannot be ignored when measuring the air leakage of the galvanized air duct are that we measure the air leakage of the galvanized air duct at night to ensure that the surrounding environment is dark. Place the 100W low-voltage lamp with protective cover on the inside or outside of the air duct, move slowly along the detection position and joint, and observe on the other side. If light is found, it indicates that there is obvious air leakage, and make records.
