Desgin And Anaylsis Of Miniature Positive Displacment Of Pump

Abstract

The design aimed at providing the down-stream sector of the petroleum industry and the  small scale industry with an indigenous pump that could deliver about 4.09123x10-4m3/s  (24.55litre/minute) of hydraulic oil. Pump is a device that enables mechanical energy to be  imparted to a fluid and manifests in pressure energy increase. Pumps have wide applications in  science and engineering including, public water supply, irrigation, up-steam/down-stream  petroleum sector, auto-mobile, haulage equipment and chemical dosage. Gear pump is the main  choice of fuel system designers due to long life, low maintenance cost and high performance.  In this thesis, the static analysis is to determine the deformation ,stress and strain at  different speeds (4000 and 2000 Rpm)of the gear pump for different materials (mild steel,  stainless steel and C24 steel).  In this the CFD analysis ie to determine the pressure Drop, velocity,and mass flow rates  at different mass flow rates(24.55,40 and 60lit/min).  3D modeling by the CREO parametric software ,analysis done inANSYS
