Presentation on mine pump

  1. 1. MINE PUMP
  2. 2. 1. Principle 2. Main parts 3. Working mechanism 4. Efficiency 5. Advantage & disadvantage 6. Multistage 7. Characteristic curves of single stage centrifugal pump 8. Pump selection Overview
  3. 3. Dynamic pump Positive Displacement pump Pump Centrifugal Pump Peripheral Pump Mixed Flow & Radial Flow Rotary Reciprocating Pump
  4. 4. First centrifugal pump invention by 1475 in a treatise by the Italian Renaissance Engineer . The centrifugal pump work on the principal of forced vortex flow. Convert the mechanical energy into hydraulic energy by centrifugal force on the liquid. Constitute the most common type of pumping machinery. Used to move liquids through a piping system Introduction and Principle Of Centrifugal Pumps
  5. 5. Main Part Of Centrifugal Pump I. Impeller II. Casing III. Suction Pipe With A Foot Valve IV. Delivery Pipe
  6. 6. Simplest piece of equipment in any process plant Energy changes occur by virtue of impeller and volute Liquid is fed into the pump at the center of a rotating impeller and thrown outward by centrifugal force The conversion of kinetic energy into pressure energy supplies the pressure difference between the suction side and delivery side of the pump Working Mechanısm Of A Centrifugal Pump
  7. 7. MANOMETRIC EFFICIENCY Manometric head man = Head Imported By Impeller To Water MECHANICAL EFFICIENCY Rotor Or Impeller Power mech = Shaft power OVERALL EFFICIENCY Power Output Of Pump o = Power Input Of Pump
  8. 8. 1. Its initial cost is low 2. Efficiency is high. 3. Discharge is uniform and continuous 4. Installation and maintenance is easy. Advantage Of Centrifugal Pump
  9. 9. • Cannot handle highly viscous fluids efficiently • Cannot be operated at high heads • Maximum efficiency holds over a narrow range of conditions Disadvantage Of Centrifugal Pump
  10. 10. • When a centrifugal pump consist of two or more impellers the pump is know as a multistage centrifugal pump. • Shaft or on different shafts is called the Multistage centrifugal pump. 1. To produce a high head 2. To develop a high discharge Multistage Centrifugal Pump
  11. 11. If a high head is to be developed the impeller are connected in series or same shaft . Total head developed= n × hm where, hm = head developed by one impeller n = no. of impellers in series To Produce A High Head
  12. 12. If discharging large quantity of liquid the impeller are connected in parallel To Discharge A Large Quantity Of Liquid Total Discharge = N X Q
  13. 13. 1.Main characteristic curves Characteristic Curves Of Single Stage Centrifugal Pump Main Characteristic Curves
  14. 14. If speed is kept constant, the variation of manometric head, power and efficiency with respect to discharge Operating Characteristic Curves
  15. 15. Head vs. Efficiency & Efficiency vs. Discharge Constant Efficiency Curve
  16. 16.  The amount of fluid  The properties of the fluid  Type of power supply  Cost and mechanical efficiency of the pump Pump Selection
  17. 17. 1. Centrifugal pump is a kind of machinery used for pumping water through the centrifugal movement 2. Positive displacement pumps will always be more efficient than centrifugal pumps due 3. As a conclusion, we had obtained a performance curve at 3 different speed of pump by avariable characteristic. The efficiency of pump have related to the losses mean energy during the process. This efficiency will be increase if less loss occur. Conclusion
  18. 18. Magnetic-drive Model 620-mc Suction Port Size = 1.00 in Discharge Port Size = 0.75 in Impeller Diameter = 3.75 in Impeller type = Open Maximum speed = 3600 rpm Maximum Flow Rate = 45 gpm Maximum Differential head = 65 ft Minimum Operating temp. = -40 F Specifications of Centry® Series Magnetic-Drive Centrifugal Pump
  19. 19. Maximum Operating Temp. = 500 F Maximum Operating pressure- = 3002 PSI Pump w/Threaded Ports & Bracket = 30 lbs Pump w/Flanged Ports & Bracket- = 34 lbs Power frame- = 16 lbs S-Adapter- = 6.0 lbs
