The installation steps of explosion -proof roofs are generally as follows:
Installation location is determined: First, the installation location of the explosion -proof roof fan needs to be determined.This position should be far away from flammable and explosive items, and consider whether the exhaust port of the fan can be connected to the outdoor air.For roof fans, the installation location needs to be higher than the roof and the surface is flat to prevent water seepage and leakage.
Installation foundation processing: Before installing a fan, the foundation of installation needs to be processed.Make sure the foundation is firm and firm to ensure the stability and normal operation of the fan installation.For the roof fan, the foot bolts need to be buried in advance.
Fan installation:
Measure the size of the roof hole to ensure that the size is larger than the size of the fan itself, so that the fan can be installed smoothly.
Put the explosion -proof roof fan into the hole to ensure that it is in the right place.Use corner steel or other appropriate fixed pieces to fix it on the roof around the hole.Note that the fan must be installed on the roof higher, and there are no obstacles around.
Add a layer of 5mm rubber plates between the fan base and the cornerstone to reduce vibration.The ground foot bolt should be equipped with a spring cushion ring to prevent loosening due to force.
Install a protective device: Install the protective cover and windfinder on the fan to prevent the debris from entering the fan and protect the fan from being damaged.
Electric wiring: According to the requirements of the electrical control system of the fan, the correct wiring connection is performed to ensure the normal operation and safety of the circuit.
Install insect -proof net: In order to prevent insects or other small animals from entering the fan, insect -proof nets need to be installed at the wind in the air in the fan.
Connecting duct: If the fan is required to connect to the duct, the hose (flexible material and not burning) should be used for connection.The length of the hose should not be less than 200 mm, and the pipe diameter should be the same as the import and export size of the fan.
Inspection and commissioning: After the explosion -proof roof fan is installed, the necessary inspection and commissioning work is performed.Check whether the turning of the fan is normal and whether the electrical system is stable to ensure that the fan can work normally.
Throughout the installation process, the operating guide should be strictly observed and ensured that the installer has sufficient professional knowledge and skills.At the same time, high -quality explosion -proof fans should be selected, and regular inspections and maintenance should be performed to ensure its safe and efficient operation.
