13.0 Recommended maximum allowable piping forces and moments on blower
connections
13.1 Inlet flange
FX = 85 KG FY = 200 Kg FZ = 160 Kg
MX = 125 kgm MY = 65 kgm MZ = 65 kgm
13.2 Outlet flange
FX = 80 kg FY = 200 kg FZ = 150 Kg
MX = 110 kgm MY = 55 kgm MZ = 55 kgm
where :
F = force
M = moment
X = Axial - parallel to rotor centre line
Y = Vertical
Z = Horizontal - normal to rotor centre line.
14.0 Vibration and noise
Vibration tolerance: 4,5 mm/s RMS
Vibration shall not exceed 4,5 mm/s RMS when measured in the vertical plane at the
bearing housings with the blower operating at the design speed.
Sound level: please refer to the calculation data sheet
II - PERFORMANCES
1. All tests if required are in conformity with ASME Power Test Code 10.
2. For constant speed blowers:
- The head shall be within the range of 100% - 105% of the normal head at design capacity,
- The horsepower based on measured head shall not exceed 107% of the value at the specified
normal operating point.
3. For variable speed machines:
- through the rotational speed, the head shall be adjusted as close as possible to the design point,
with zero negative tolerance,
- the horsepower at that point shall not exceed 104% of the predicted shaft power value.
