Tunnel fans inevitably generate noise during operation, including aerodynamic noise and mechanical noise. Among them, aerodynamic noise is the main noise, and its sound pressure level is usually more than 10 decibels higher than mechanical noise. It propagates into the surrounding air through the in
查看详情How to improve the efficiency of tunnel jet fans by using imported specialized machines and specialized machines imported from machining wheels to reduce noise through improving corrosion resistance, reliability, economy, and muffler? Today we are working together, hoping to help you.1. Strengthen v
查看详情Tunnel fans have been widely used due to their advantages such as corrosion resistance, reliability, economy, and noise reduction. Direct drive and low maintenance work. Today, let's connect the principle of tunnel jet fan connection.Fan shaped tunnelThe installation of the fan control room is a
查看详情Method for setting up jet fans for tunnelsThe foundation of the tunnel fan is firmly horizontal, with a height of 200mm.2. The tunnel fan and air duct are connected through a soft connection (flexible material and non combustible) of the fan, with a length of not less than 200mm, and the pipe diamet
查看详情The pulley is the most important part of the drive system in tunnel fans, and it is also the main component in the operation of tunnel fans. Therefore, we need to regularly check the wear of the pulley. Regarding the pulley, how should we maintain and repair it in daily useThe pulley is the most imp
查看详情Tunnel axial flow fans adopt strict quality standards in the fan manufacturing process, but in addition to quality control, fan manufacturing enterprises are also an important component of fan assembly to prevent serious damage to installation efficiency. Tunnel axial flow fans should be installed s
