Submersible pump

  1. 1. SUBMERSIBLE PUMP By: G.Krishna Vamsy
  2. 2. In 1928 Russian engineer and inventor Armais Arutunoff successfully installed the first submersible oil pump.  In the mid 1960s the first fully submersible deep-well water pump was developed. Inventor of the electric submersible pump.
  3. 3. In his design, the motor was ingeniously installed below the pump to cool the motor with flow moving up the oil well casing, and the entire unit was suspended in the well on the discharge pipe
  4. 4. A vertical type centrifugal pump close- coupled to a small-diameter submersible motor is termed as a submersible pump. It is diffuser type vertical centrifugal pump. Specially adapted to pumping water from tube wells.
  5. 5. Constructional Details: It consists of Pump bowl Motor assembly Discharge column Head assembly Water proof cable to conduct current to the submerged motor.
  6. 6. Electric Submersible Motor: It is longer than an ordinary motor. It may be dry or wet type. The electric cable from motor to switch board is water proofed and sealed.
  7. 7. Pump Element: Pumps with radial flow impellers- low capacities and high heads Mixed flow impellers-for medium capacity and medium heads.
  8. 8. Diffuser: After the fluid has left the impeller, it is passed through a ring of fixed vanes(diffuser) that diffuse the liquid, providing a more controlled flow and a more efficient conversion of velocity head into pressure head.
  9. 9. Before starting the pump the direction of rotation should be checked. The direction which gives more pressure is chosen. Permissible limit of sand-25 grains/cubic meter of water. The shutdown period of pump should not exceed more than 2 weeks.
  10. 10. DO' S: Always suspend the pumpset at least 3 meters above the bottom of the bore. The pumps must be installed 1meter below the water level surface. Check the water quality before filling in the motor. Always check the cable joints and vertical play after coupling the pump set. Always use a good quality control panel. Bending of cable must be avoided
  11. 11. DON' T: Don't run the pump if any of the following defects are observed.  Water is sandy or acidic.  If there is no water.  If the problem of single phasing arises. Don't pull the motor with the help of cable. Minimum interval between the start and stop of the motor must be 1 minute
  12. 12. The capacity of the submersible pump is determined by the width of the impeller and diffuser. The pressure is determined by the diameter of the impeller, the speed and the number of impellers.
  13. 13. APPLICATIONS: In sewage and general industrial pumping. In sea water handling and deep well drilling. In oil wells.
  14. 14. ADVANTAGES: Can be used in very deep wells where a long shaft is not practical. Unaffected by deviations in vertical alignment of well. More efficient than jet pumps. It can be used in places where above the ground housing is inconvenient. It can be used in wells of diameter as small as 15 cm. Less noise.
  15. 15. Disadvantages: Affected by seasonal fluctuations in water level. It can run only on electric motor not on an I.C. engine. Maintenance is difficult. Higher initial costs Problem of corrosion.

  17. 17. PULSOMETER STEAM PUMP
  18. 18. The Pulsometer steam pump is a pistonless pump. The invention was inspired by the Savery steam pump invented by Thomas Savery. Around 1890’s it was a popular and effective for quarry pumping.
  19. 19. OPERATION: It operated by the direct action of steam on water. The mechanism consisted of two chambers. As the steam condensed in one chamber, it acted as a suction pump, while in the other chamber, steam was introduced under pressure and so it acted as a force pump. At the end of every stroke, a ball valve consisting of a small brass ball moved slightly, causing the two chambers to swap functions from suction-pump to force- pump and vice versa. The result was that the water was first suction pumped and then force pumped.
  20. 20. ADVANTAGES: High efficiency Compact form Durability Adaptability
