Vertical wind tunnel fan motor ventilation system

1/18/2013 6:41:37 PM

 

Fan motor is the heart of the wind tunnel, installed in almost airtight fan in the period. In order to ensure the safe operation of the fan motor, must take ventilation cooling measures. This paper analyzes the other wind tunnel fan motor ventilation system present situation, put forward vertical wind tunnel fan motor fan using frequency control of motor speed control, embedded in the power system automation environment, air quantity with the fan motor speed and stator automatic temperature change, improve the degree of automation, save electric energy, improve the fan starting condition, the noise reduction effect, have bigger application value.
Vertical wind tunnel is built by our design the first large-scale vertical wind tunnel, the single return form, circular open test section, test section wind speed range 5 m/s, is mainly used to carry out the plane tail spin, parachute, rotating balance, helicopter vertical lifting and test technology research.
