Q1: An eight blades fan with mass 50 kg having diameter of 350 mm, width 50mm is running CCW at 2000 rpm. The first blade is at zero degree and motor power is 5kw. The following vibration data was collected in the field during balancing process. Perform balancing of rotor using Vector Method. First Run: V = 12mm/s, at 55 degrees Trial Run: V = 7 mm/s at 160 degree Final Run: V = 5mm/s ANSWER the following: 1- Machine dynamic class 2- Single or multiplane 3- Balance quality grade of machine 4- Permissible specific unbalance 5- Correction mass and its position 6- Perform trim balancing (if required) 7- Weight splitting (if required) 8- Sketch your balancing set-up Q1: An eight blades fan with mass 50 kg having diameter of 350 mm, width 50mm is running CCW at 2000 rpm.
