It's well-known that tunnels are equipped with specialized ventilation fans, known as tunnel jet fans, which can also be referred to as tunnel fans or tunnel ventilation fans. When using tunnel jet fans, it's crucial to pay attention to aspects such as whether the control cabinet operates normally after startup, if there are any issues with the motor, and whether the values on the ammeter fall within the normal range. In fact, these all have intricate connections to the correct installation of the tunnel ventilation fan. How to install a tunnel jet fan?
All tunnel jet fans and electrical components are installed on a solid steel bracket. The steel bracket is mounted on vibration-isolating pads on the top plate of the foundation. The vibration pads must be made of porous rubber boards. The steel bracket of the tunnel jet fan must be mounted on a concrete foundation, and rubber vibration pads should be added between the steel bracket and the foundation.
The bottom of the tunnel jet fan should be placed on a level surface and securely fastened. The height should not exceed 200 millimeters.
③ The diameter of the tunnel jet fan inlet can only increase, not decrease. A bug screen must be installed at the outlet, and a rain and wind hat should be added when blowing air upwards. How to install the tunnel jet fan?
The selection of tunnel jet fan and ducts should use soft connections, with lengths not less than 200mm and pipe diameters matching the inlet size of the fan. For canvas hoses installed at the intake end of the tunnel jet fan, they can be slightly tighter to prevent them from being吸入 during operation and to increase the cross-sectional size of the canvas hose. To ensure that the soft connections of the tunnel jet fan do not deform during system operation, a gradual transition in thickness should be installed.
