ANSI HI Rotodynamic (Centrifugal and Vertical) Pumps Guidelines for. HI Pump Vibration Standards. ▫ Standards and guidelines for how much is too much? ▫ Standards available. • ANSI/HI ‐ Rotodynamic.
New content on vibration criteria at the top of the motor for vertical pumps. Solids-handling pumps with single-vane impellers excluded in the scope of the standard. Tri-axial anvil mount removed from permanent rigid mount of transducer recommendations. VS2 icon updated in Figure 9. New content on managing vibration of vertical structures recommendations.
To control the amplitudes vibrations, it is necessary to know the distribution of the natural frequencies, so it helps to design cylindrical shell cylindrical shell for optimum vibration control .
This paper illustrates modal analysis of vertical turbine pump base stool cylindrical shell. This paper also describes how to move natural frequency of the base stool cylindrical shell of VTP by stiffens existing cylindrical base stool shell.
The bottom end of the base stool is rigidly fixed with foundation with mechanical fasteners. The other end of the base stool, motor is mounted which drives centrifugal pump at a speed of rpm which gives best efficiency for given head.
Following steps are performed to carry out finite element analysis. Table 1: Material Properties Sr. Model is meshed with tetrahedral elements. Total number of nodes and elements are and respectively. Boundary condition of base stool is such that its bottom end is fixed i. Top end of base stool cylindrical shell is free. Table 2 presents first six natural frequency of base stool.
Figure 4 shows fifth and sixth mode shapes of vibration. So, to move natural frequency of base stool cylindrical shell away, stiffness has to be increased.
Figure 5 shows modified design of VTP base stool cylindrical shell. First six natural frequency of modified model is shown in table 3. Also first two mode shapes of vibration are shown in Figure 6. By modifying design of base stool cylindrical shell at earlier stage, resonance can be avoided which leads to catastrophic failure of cylindrical shell casing.
