BASE FRAME OPTIMIZATION OF MULTISTAGE PUMP AND SHAFT DEFLECTION ANALYSIS AS PER API STANDARDS

Base Frame are the traditional and most common means for reducing weight of pump. Over past many years, changes had to be made to pumps and parts of pumps to improve performance. Base Frame, Shaft, bearing are the key components of any single stage or multistage pump. T herefore to obtain better performance of multistage pump, different theoretical cases have been studied by changing length of I - section, by changing size of supporting channel etc. Then these cases have been analyzed for the stresses coming on the componen ts of base frame, shaft etc. of pump by using design formulae / data book and CAD /CAE software’s like HYPERWORKS /ANSYS .The vibrations can be controlled and also life of pump can be increased by base frame optimization and shaft deflection analysis
