Specification for power distribution equipment installation of fire exhaust fan

Release Time：2021-07-20

installation of fire exhaust fan:
1. Understand the sample of the fire-fighting smoke exhaust fan, the specifications, models, methods, rotation direction of the centrifugal impeller and cyclone entry and exit direction of the fire-fighting smoke exhaust fan. Before installation of the fire-fighting smoke exhaust fan, check whether the centrifugal impeller is rubbed or not, and check whether the accessories are detailed and whether the components are firmly connected. Check carefully whether the fan blades are damaged or deformed due to transportation, or they should be repaired before installation.
2. The ventilation duct connecting the import and export trade of the fire-fighting smoke exhaust fan shall have an independent supporting point. The net weight of the pipeline is allowed to be added to the components of the fire-fighting smoke exhaust fan. When installing the fire-fighting smoke exhaust fan, the horizontal position of the fire-fighting smoke exhaust fan should be paid attention to. The connection between the fusion surface of the fire-fighting smoke exhaust fan and the roadbed and the air inlet pipeline should be adjusted to make to make sure that it conform to make.
3. After the installation of the fire-fighting smoke exhaust fan, pull the centrifugal impeller with your hand or lever to check whether it has experienced tight or rubbing conditions and whether there are any objects that hinder the rotation. If there is no abnormality, the trial operation can be carried out. The exposed part of the wind-fighting smoke exhaust fan needs a protective cover (for customer standby). If the air inlet of the fire-fighting smoke exhaust fan is not connected to the channel, a protective net or other safety device (for customer standby).
4. The wiring of the fire-fighting smoke exhaust fan must be appropriate and reliable. The casing of the fire-fighting smoke exhaust fan should be properly grounded. The grounding device must be reliable. The switching power supply for the fire-fighting smoke exhaust fan must be detailed and conform to relevant regulations. The wiring of electrical equipment must have professional electrician wiring.
The power distribution equipment of the fire-fighting smoke exhaust fan does not meet the requirements. First, the power supply and distribution system of the fire-fighting smoke exhaust fan does not meet the requirements of the load level for civil construction of high-rise residential buildings. Some power supply system routes are not connected from fire-fighting power supply, but only led to building lighting boxes. Some overall planning uses single control loop power distribution equipment routes. Some overall planning does not have end switching power supply conversion machinery and equipment, which are not up to the special type double loop power supply specified for the loads of primary and secondary power supply systems, and the end conversion machinery and equipment standards are set.
The installation of the distribution equipment route does not meet the requirements. Some fire smoke exhaust fan power distribution equipment route wear PVC plastic pipe, some wear metal hose without brushing fireproof material, do not conform to the function of the threading pipe.
