Transcript

  • 1. Basic Pumper/ApparatusOperations-Equipment Presenters: FF/Eng. Andy Grove Captain/Eng. Mark Goerger Northwest St. Clair County Fire Protection District Updated 2012
  • 2. Topics to be discussed: Pump design Gauge functions Line pressures Supply lines Standpipes/sprinklers Hydrants Hands-on
  • 3. Pump Design
  • 4. Pump Types Piston pumps Rotary pumps Centrifugal pumps
  • 5. Piston Pumps First types of pumps used for firefighting Very simple  Pumps water and air Single or double displacement Very efficient Lack volume
  • 6. Rotary Pumps Developed to be used with steam engines Still used today  Primer pump Rotating gears create pressure Pumps water and air
  • 7. Centrifugal Pumps Used today Uses impellers  Cannot pump air Series vs. parallel  Series = pressure  Parallel = volume Transfer valve
  • 8. Centrifugal Pumps Parallel mode  Water enters pump through two intakes  Twice the volume at same pressure
  • 9. Centrifugal Pumps Series mode  Water enters one side and is then thrown to the other side  Double pressure, half volume
  • 10. Centrifugal Pumps
  • 11. Gauges and Controls Pump switch  Truck stopped  Transmission = neutral  Parking brake  Lever down  Transmission = drive Look and listen
  • 12. Gauges and Controls Tank to pump  Brings water from the booster tank to the fire pump Not used when running directly off a hydrant
  • 13. Gauges and Controls Tank Fill / Re-circulate  Fills the booster tank  Re-circulates water from discharge back to intake Keep closed when flowing water  Open when sitting idle Overflow under truck
  • 14. Gauges and Controls Relief valve  Equalizes pressure on all discharges  +/- 10 psi. pressure  Simple on/off switch
  • 15. Gauges and Controls Relief valve  Mechanical spring valve  Set highest discharge pressure  Decrease slightly
  • 16. Gauges and Controls Throttle control  Turn clockwise  Increase throttle  Turn counter-clockwise  Decrease throttle  Emergency operation  Push red button in
  • 17. Gauges and Controls Transfer valve  Pressure  Volume Operate when pumping more than ½ the rated capacity of the pump  500 gpm +
  • 18. Gauges and Controls Primer  Rotary pump  Pumps air and water Drafting Lose prime in fire pump Pull handle 30-45 seconds  Water will spray under the truck
  • 19. Gauges and Controls Compound gauge  Intake pressure  Discharge pressure Drafting – vacuum pressure  Inches of mercury
  • 20. Gauges and controls Discharges  Control pressure to each line Control each line  Gate / feather Pull out on handle to operate Turn 90 degrees to lock
  • 21. Gauges and Controls Discharges  Control pressure to each line Control each line  Gate / feather Pull back on the handle Turn clockwise to lock
  • 22. Gauges and controls Control panel on 4224  Throttle controls  RPM/Pressure mode
  • 23. Gauges and controls LDH intake  Gated valve  5” hose connection  Storz connection
  • 24. Gauges and controls Aerial Flow meter  Rear panel on 4229  Digital display  Gallons per minute
  • 25. Gauges and controls Aerial Discharge Valve  Directs flow of water up the pre-piped waterway  Post indicator comes out when valve is open
  • 26. Line pressures Calculating engine pressure  Variables  Hose length  Hose diameter  Nozzles, appliances, etc.  Elevation  Friction loss standards
  • 27. Line pressures Attack lines  1 ¾” hose  100 feet long  Friction loss  32 psi.
  • 28. Line pressures Attack line/supply line  2 ½” hose  100 feet long  Friction loss  Depends on volume and pressure
  • 29. Supply lines Large Diameter Hose  LDH or 5” hose
  • 30. Line pressures Nozzles  Smooth bore  Fog nozzles
  • 31. Line pressures Smooth bore nozzle  Stacked tips  Bail  Friction loss  Hand line  50 psi.  Master stream  80 psi.
  • 32. Line pressures Fog nozzle  Bail  Volume selector  Friction loss  100 psi.
  • 33. Line pressures Discharge pressure  Nozzle + Hose + Appliances (+ or -) Elevation Example:  200 foot pre-connected 1 ¾” hose with a fog nozzle  100 psi (fog nozzle) + 60 psi (32 psi hose X 2) = 162 psi  NWFD = typically 144 - 150 psi
  • 34. Line pressures Hose lines  Longer hose lays = higher friction loss  Smaller hose = higher friction loss  Fog nozzles = higher friction loss than smooth bore Things to think about:  Long hose lays  Multiple lines off
  • 35. Standpipes and sprinklers Locations  Kings House  Shrine  Firehouse crossing  Others??
  • 36. Standpipes and sprinklers Standpipe  Connect 2 ½” hose to fire dept connection  Discharge pressure  25 psi + hose
  • 37. Standpipes and sprinklers Sprinkler connection  Connect 2 ½” hose to fire department connection  Discharge pressure  150 psi
  • 38. Hydrants
  • 39. Hydrant Detail Dry Hydrant
  • 40. Hydrant Volumes Colored Bonnets  Blue = 1500 gpm +  Green = 1000 – 1499 gpm  Orange = 500 – 999 gpm  Red = less than 499 gpm
  • 41. Opening Hydrants
  • 42. Opening Hydrants “Hydrant man”  Get off the truck ready to go to work  PPE  SCBA  Tools  Grab a radio!
  • 43. Opening Hydrants Pull hose and hydrant bag off apparatus  DO NOT FORGET THE HYDRANT BAG!!!
  • 44. Opening Hydrants Hitting a hydrant  Wrap end of hose around hydrant  Signal for driver
  • 45. Opening HydrantsDO NOT STAND ON THE HOSE!!
  • 46. Opening Hydrants Opening the hydrant  Flush first, then connect  Charge when told/signaled  Open slowly  Open up 100%
  • 47. Opening HydrantsDO NOT CHARGE BEFORE ENGINEER IS READY!!
  • 48. Connecting the supply line LDH intake  Connect LDH  Charge hydrant  Open petcock valve  Allow air to escape  Close petcock valve  Open gate valve
  • 49. Basic Pumper/Apparatus Operations Any Questions???
