The following aspects should be paid attention to when starting ventilation equipment:
1. Before start-up, the inlet air conditioning valve of the fan should be strictly closed to avoid misoperation and start with load.
2. After the ammeter indication is restored to the no-load current, the adjustable throttle opening is in the proper position.
3. When starting, the blower stops quickly after starting, so as to judge whether the blower can have abnormal phenomena. If the blower is found to have abnormal and decisive discontinuation of operation, check that the blower can start normally before cleaning up the defect.
4. Check whether the lubricating oil level of the bearing is normal, the water supply condition of the cooling water pipe, whether the coupling is in good condition, whether the repair hole door can be blocked;
5. Pay attention to the start-up time and whether the no-load current is normal.
6. Ventilation equipment operation inspection is abnormal;
7. In order to prevent the impurities in the clean fan from being cleared when the fan device of the new device is installed, it is necessary to stop the fan quickly after starting the fan, and to judge whether the fan can have abnormal phenomena. If the fan is found to have abnormal and decisive discontinuation of operation, it is necessary to check the normal start-up before cleaning the fault.
Five key points in the process of ventilation pipeline are as follows:
Air duct: A pipe made of metal, non-metal sheet or other materials for air circulation.
Wind Channel: It is made of concrete, brick and other building materials and is used for air passage.
Ventilation engineering: general name of supply air, exhaust air, dust removal, pneumatic delivery and smoke prevention and exhaust system engineering.
Bite: The edges of metal sheets are bent to form a certain shape, which is used to fix and connect each other.
Air conditioning engineering: general term for air conditioning, air purification and clean air conditioning systems.
