What should be paid attention to when the fire fan

date:[2021-02-24]     pk_hits:

In recent years, the demand for fire-fighting fans has continued to increase.


It also shows that today's society is increasingly aware of fire safety.


Fire-fighting fans provide convenience for everyone. What should be paid attention to when using fire-fighting fans? Stainless steel fire fan


In fact, the fire fan is divided into single speed and double speed.


When we choose fire fans, single-speed and double-speed fire fans should pay attention to those usage problems!


Today, I found some information on single-speed and dual-speed fire fans on the Internet, and share with you;


Pay attention to the use of single-speed fire fans:


1. Before unpacking the fire fan, check whether the packaging is intact, whether the nameplate parameters of the fire fan meet the requirements, and whether the accompanying accessories are complete and complete.


2. Carefully check whether the fire fan is deformed or damaged during transportation, whether the solid parts are loose or falling off, whether the impeller is rubbed, and check all parts of the fan.


If an abnormal phenomenon is found, it should be repaired before use.


3. Use a meter to measure the insulation resistance between the fire fan shell and the motor windings. The value should be greater than megohm, otherwise the motor windings should be dried. The temperature during drying is not allowed to exceed 120 degrees.


4. Prepare all the materials, tools and sites required for the installation of the fire fan.


What problems should be paid attention to in the use of two-speed fire fans


Please pay attention to the motor wiring and coil problems during the installation of the fire fan.


In the past, customers' independent wiring caused the motor to run abnormally or even burn out. I hope that users can be cautious when using the two-speed fire exhaust fan in the later period.


During the operation of the fire-fighting fan, pay attention to the fan's operating time and the degree of fan oil. Generally, there are three options of weak, medium and strong.


The maintenance personnel of the fire fan should pay great attention to this problem during maintenance.


And the temperature can be controlled to about three degrees Celsius,


And during the normal operation of the range hood, the speed inside is very important.


In order to maintain the normal operation of the speed, attention should be paid to the internal cleaning of the two-speed fire fan.


The grounding of the fire fan shell or motor shell must be reliable,


It is forbidden to rotate in the opposite direction,


It is forbidden to run over rated current,


It is forbidden to run the fire-fighting fan bearing oil refueling times not less than 1000 hours/time during the lack of phase operation.


It is forbidden to maintain the fan during operation.
