Titanium fan is essentially the 1 kind of variable current constant pressure device. When the speed is constant, the pressure flow theory curve of centrifugal fan should be straight line. Due to internal losses, the actual characteristic curve is bent. The pressure generated by a centrifugal fan is greatly affected by changes in intake air temperature or density. For a given intake air volume, the highest intake air temperature produces the lowest pressure when the air density is the lowest. For a given pressure and flow characteristic curve, there are power and flow characteristic curves. When the blower is operated at a constant speed, the required power increases as the intake air temperature decreases.
Titanium fans are used for ventilation or high-temperature smoke exhaust in high-rise buildings, underground buildings, tunnels, drying rooms, etc. It can run continuously for more than 60 minutes at a high temperature of 300 degrees Celsius, and it will not be damaged for 20 hours/time at a medium temperature of 100 degrees Celsius. Is the ideal fire facilities! When we use it, we should let it work in a normal working environment, and don't let it work in a harsh environment. This can easily lead to damage to the exhaust fan. Generally speaking, when the medium temperature is not higher than 5 ℃, the two-speed fire-fighting high-temperature exhaust fan should not work for a long time at a high temperature above 300 ℃.
