Civil air defense equipment has an important purpose in the construction of buildings, mainly in the form of underground garages, set up civil air defense doors, blocking doors, lighting, ventilation, water supply and drainage, communication network required hardware. The ventilation equipment of civil air defense engineering is an important equipment for the survival of personnel, which is directly related to the safety of personnel and plays a very important role. During the construction process, the installation of ventilation equipment needs to comply with the relevant regulations.

The installation of the fan should comply with the following regulations: the impeller rotation direction is correct during the test run of the fan. The operation shall not be less than 2 hours, the temperature rise of the sliding bearing shall not exceed 35 °C, and the high temperature shall not exceed 70 °C; the temperature rise of the rolling bearing shall not exceed 40 °C, and the high temperature shall not exceed 80 °C; the centrifugal fan shall be in close contact with the damping pedestal, and the bolt shall be tightened and the anti-loosening device; when the pipeline fan is installed by the damping hanger, the fan shall be closely connected with the damping hanger, which shall be firm and reliable; and the fan shall be closely connected with the damper, the bracket and the bracket when the bracket and bracket are used for installation, which shall be stable and reliable. The installation of the dehumidifier and the cabinet air conditioner should be stable and firm, and the two flanges should be naturally flush on the same shaft. No forced connection, tight connection, no air leakage.

The installation of the muffler should comply with the following provisions: the muffler frame needs to be used, the size of the resonance cavity partition is correct, the partition is tightly connected with the wall plate, the shell is tight, the muffler is installed in the correct direction, and the bracket (hanging) frame is set separately; the fixed end of the muffler is firm and the distance between the pieces is uniform after the installation of the muffler monomer; the muffler material is

pasted firmly and flatly, the bulk material is filled evenly, and there is no obvious sinking; the muffler composite material is spliced along the direction of the air flow without damage; the perforated plate has no burrs and the hole spacing is uniform.
