DETAILED ENGINEERING DESCRIPTION - CONTINENTAL INDUSTRIE
DEB031EN – 04/2010
4/4
12.0 Recommended maximum allowable Piping forces and moments on blower
connections
12.1 Inlet flange
FX = 30 KG FY = 75 Kg FZ = 60 Kg
MX = 45 kgm MY = 22 kgm MZ = 22 kgm
12.2 Outlet flange
FX = 30 KG FY = 75 Kg FZ = 60 Kg
MX = 45 kgm MY = 22 kgm MZ = 22 kgm
where :
F = force
M = moment
X = Axial - parallel to rotor centre line
Y = Vertical
Z = Horizontal - normal to rotor centre line.
13.0 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.
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.
