Transcript of "pump underpinning assesment questionair"

  1. 1. 1. Cause of pump Vibrations ANS: Misalignment 2. The Most common type of pump is.. ANS: Centrifugal Pump 3. On a multiple screw pump, the motor that is driven by the timing gears is called .. ANS: Drive Motor 4. The things I need to know about a pump before I begin a routine inspection are.. ANS: Normal Flow Rate, Operating temperature, type of liquid, Normal Discharge Pressure 5. What type of Head exist on the discharge of a pump when the pump is not running? ANS: Suction Head 6. All the parts that need to be inspected when checking a pump for leaks… ANS: Mechanical Seal & Internal Seal 7. Cavitations can be caused by an increase in… ANS: the temperature of the process liquid. 8. Minimum net positive suction head is the least amount of suction head is required to… ANS: prevent cavitations 9. What can be done to stop or minimize cavitations? ANS: The suction pressure can be increase 10. The problem that can happen when the pumped fluid temperature is too high is….ANS: Cavitations
  2. 2. 11. Wecompare the actual flow rate through a pump, to the design flow rate to find… ANS: Efficiency 12. Thepossible cause of an improper pressure reading on a suction line… ANS: A blocked strainer 13. Whichvalves are normally opened when starting a centrifugal pump.. ANS: Suction Valve 14. The function of a valve is…. ANS: To move fluids from one point to another 15. Theproblems that can cause a pump to have an improper instrumentation readings Are… ANS: Blocked pipe, valve in wrong position & wrong pump parts. 16. What is usually the RESULT of cavitations… ANS: Worn internal pump parts. 17. Minimumnet positive suction head is usually referred to in.. ANS: Level or pressure 18. What is the result of severe cavitations? ANS: Pitting of internal pump surface 19. On a running centrifugal pump, what piece of equipment reduces leakage from discharge to suction side.. ANS: Wear ring
  3. 3. 20. The place where it is not normal to find even a small amount of leak is.. ANS: bearings 21. What effect do pumps that are operating in series have on the fluid.. ANS: Increase the fluid pressure. 22. Duringa routine pump inspection, is not usually necessary… ANS: to adjust the mechanical seals leak off rate. 23. Name4 types of pumps.. ANS: Centrifugal, reciprocating, gear &lobe. 24. Name2 types of pumps found in YOUR plant.. ANS: centrifugal &reciprocating pump. 25. Whatis SOP? ANS: Standard Operating Procedures 26. Nametwo types of valves found in your plant.. ANS: Gate Valve , Pressure relieve valve. 27. Name 4 types of valves… ANS: Gate valve, pressure control valve, ball valve, & pressure relieve valve. 28. Whatdo you do when you find that the pump is leaking? ANS: report to the shift team leader. 29. List 4 risk control measures to minimize risk? ANS: Use Permit-to Work System, Conduct Risk Assessment, conduct Tool-Box meeting & wear proper PPE.
  4. 4. 30. What kind of drivers are there in a pump? ANS: Electrical motors,pneumatic motors driven by compressed air,steam turbines gas turbines & diesel/petrol engines.(booklet page 21) 31. What are process parameters? ANS: pump flow discharge pressure, flow temperature, flow rate, motor meter current(amp). 32. Where can I find the specifications of the pump? ANS: Mechanical catalogue/manuals.
