Under the high temperature of 280 ° C at 280 ° C, it can work for more than 30 minutes in a row, and can work continuously for 20 hours without damage at 100 ° C temperature.Fire fans of certain models can be used for ventilation and smoke.Whether the installation and commissioning of fire smoke is scientific and whether the fire alarm can provide fire in time.
1. Before the fire firing fan is opened, please check whether the packaging is intact, whether the parameters on the fan nameplate meet the requirements, whether the model is correct, and whether the attachment is complete or lacking.
2. Carefully check that the fire exhaust fan has no deformation, damage, loose fastening, impeller wear, and checking the fan parts in the transportation engineering.If there is any abnormal, please contact the manufacturer to repair it.
3. The air duct connecting the entrance and exit of the fire exhaust fan must have an independent support, and the pipeline weight cannot be added to the fan component.When installing a fan, pay attention to the horizontal position of the fan.It must be adjusted to natural smooth and cannot be combined hard.
4. After installing the fire foam fan, use the handle or handle to move the impeller to check whether there is too tight or collision, whether there is any obstacle to rotate, and try to run under abnormal conditions.The exposed part of the fan blade needs to be protected.
5. The wiring of fire foam fan must be correct and reliable, the fan shell must be grounded, and the ground must be reliable.The power supply of the fan must be complete and meet the relevant requirements.
6. After the fire foam fan is installed, check whether there are leftover tools and debris left by the fan.
7. Fire fire exhaust fan allows full pressure to start or start.The full-voltage start-up current is about 5-7 times the rated current, and the voltage turning moment is proportional to the square of the voltage.In the case of insufficient power grid capacity, the starting start is used.
8. When testing, the fire fire exhaust fan needs to verify whether the wiring method is consistent with the wiring diagram according to the product instructions.Whether the component capacity meets the requirements.
9. At least two people during the trial operation, one person controls the power, and the other observe the fan work.If it is found to be abnormal, check the inspection immediately.Check whether the rotation direction is correct first.After the fan starts, check whether the running current of each phase is balanced and whether the current exceeds the rated current.If it is abnormal, it should be stopped for inspection.After 5 minutes of running, the downtime was stopped to detect the abnormality of the fire smoke exhaust fan.
10. The electric motor power required for fire foam fans refers to the high power required by the centrifugal fan and the fan when the fire fan is opened under a certain working conditions.If the air inlet is fully opened, the motor may be damaged.During the trial transportation, the valve on the fans inlet and export pipes can be better turned off, and the valve is gradually opened after running until the required working conditions are reached, and the current of the fans fire prevention work exceeds the specified rated current.
The installation and commissioning of fire exhaust fan requires professionals in accordance with the corresponding product installation instructions and debugging manuals, which requires science and rigor.When the fire occurs, whether the fire fire fan can run normally and run in time, it is related to the peoples lives and property safety.
