summary:
|
This paper presents results of vibration investigation of an industrial ventilator. threats of vibration occurrence resulting from the compressible medium flow parameters through the ventilator chamber were analyzed in detail. There have been presented measurement results taken during an industrial fan operation. Next results of tests performed in a laboratory on a smaller fan with provision of similar working conditions have been presented. Experimental tests were completed with computer simulations during which current lines, pressure and velocity distributions in the channel between the rotor blades were tested.
