Transcript

  • 1. Creation of fluid flow : Pump Objectives : Distinguish between positive and non-positive displacement pumps Understand the principle of operation of gear, vane and piston pumps Differentiate between fixed and variable displacement pumps, external and internal gear pumps as well as axial and radial piston pumps Explain how pressure-compensated pumps work Identify the various types of pumps used in hydraulics Select and size pumps for various hydraulic applications Carry out basic maintenance activities on the pumps.
  • 2. Principle of operation
  • 3. Pump classification Positive displacement pumps. Non-positive displacement pumps and ROTARY RESIPROCATING PISTON PUMP GEAR PUMPSCREW PUMP -INTERNAL -EXTERNAL VANE PUMP -GEROTER AXIAL RADIAL PISTON FIXED DISP. VARIABLE STATIONARY STA. BENT AXIS INLINE CYLINDER PISTON BALANCED UNBALANCE VARIABLE SWASH PLATE CAMDRIVEN
  • 4. Non-positive displacement pumps hydro-dynamic pump fluid is displaced and transferred using the inertia of the fluid in motion Low Initial Cost & maintenance cost Operated quietly All types of fluid like sludge and slurries High reliability Simplicity of operation
  • 5. Positive displacement hydrostatic pumps pumps discharge a fixed quantity of oil per revolution Capability to generate high pressures High volumetric efficiency Small and compact with high power to weight ratio Relatively smaller changes in efficiency throughout the pressure range Wider operating range i.e. the capability to operate over a wide pressure and speed range.
  • 6. External gear pump
  • 7. Internal gear pump
  • 8. Lobe pump
  • 9. Gerotor pump
  • 10. Vane pumps
  • 11. Balanced vane pump
  • 12. Variable displacement vane pump
  • 13. Pressure compensation in variable displacement vane pumps
  • 14. Simple circuit with variable displacement pump.
  • 15. Simple circuit with fixed displacement pump
  • 16. Piston pump Bent-axis piston pumps
