1. Adaptation environment of explosion-proof exhaust fans
Zone 1 and Zone 2 hazardous locations. IIA, IIB explosive gas environment. Zone 20 and Zone 21 are dust-proof areas with temperature groups T1~T6.
2. Product features of explosion-proof exhaust fan
The explosion-proof exhaust fan is composed of motor and blades. The appearance is beautiful, and the mounting frame is integrated, which is safe and reliable. With vibration damping device, the running noise is low. Steel pipe wiring. Meet GB3836-2000, IEC60079 standard requirements.
III. Installation of explosion-proof exhaust fan
The first step: preparation.
Before installing an explosion-proof exhaust fan, preparations are required. For example, prepare the installation tools, check whether the blades of the explosion-proof exhaust fan are deformed, whether the operation is flexible, whether the frame is firm, and then check whether the various fasteners required are complete during installation. In short, “sharpening knives does not accidentally chop woodworkers”, and being prepared will make the installation work smoother.
Step two: wiring.
The operation of the explosion-proof exhaust fan requires electric drive, so wiring is essential. In this step, what I want to say is that the wiring should be as beautiful as possible. It is best if the wiring work is done in advance. In addition, it is necessary to ensure that the voltage of the line should be consistent with the rated voltage of the explosion-proof exhaust fan, and it should be the power supply. Equipped with a small switch with explosion-proof performance.
Step 3: Wiring.
When wiring the explosion-proof exhaust fan, the wiring should be strictly in accordance with the regulations. It must be noted that when wiring, the cover of the wiring room needs to be opened. After connecting the wiring, you must ensure that the cover of the wiring room is well covered, otherwise the explosion-proof performance will be affected.
Step 4: Fix.
This step is to install and fix the explosion-proof exhaust fan in its position, which needs to be stable and firm.
Step 5: Debug and put into use.
All that needs to be done in this step is to re-check the installation of the explosion-proof exhaust fan and debug it. After everything is in good condition, the explosion-proof exhaust fan can be put into use.
