Fire pumps

  1. 1. F I R E P U M P S
  2. 2. WHAT IS A FIRE PUMP? A PUMP THAT HAS BEEN TESTED & CERTIFIED TO MEET THE MINIMUM STANDARDS SET IN NFPA 20 AS TO PERFORMANCE AND OPERATIONAL CHARACTERISTICS AND PROVIDE MAXIMUM RELIABILITY FIRE PUMPS
  3. 3. WHY ARE FIRE PUMPS USED? <ul><li>CRITICAL COMPONENT OF FIRE PROTECTION </li></ul><ul><li>SYSTEMS </li></ul><ul><li>WATER SUPPLIES </li></ul><ul><li>flow (gpm, l/m) </li></ul><ul><li>pressure (psi/bar) </li></ul><ul><li>ENHANCES WATER SUPPLY PRESSURE </li></ul><ul><li>Fire pumps cannot create water (flow) </li></ul>FIRE PUMPS
  4. 4. FIRE PUMPS - INSPECTION, TESTING & MAINTENANCE <ul><li>INSPECTIONS: </li></ul><ul><li>PURPOSE – To verify pump assembly appears to be in operating condition and is free of physical damage. </li></ul><ul><li>WEEKLY: </li></ul><ul><li>Check pump room ventilation. </li></ul><ul><li>Check pump suction & discharge valves are fully open. </li></ul><ul><li>Check suction & system pressure gauges are indicating normal pressure. </li></ul><ul><li>Check electrical system condition – “power on” pilot light is on. </li></ul>
  5. 5. FIRE PUMPS - INSPECTION, TESTING & MAINTENANCE <ul><li>INSPECTIONS: </li></ul><ul><li>WEEKLY: </li></ul><ul><li>Check diesel engine system condition: </li></ul><ul><li>Fuel tank full </li></ul><ul><li>Controller switch in “auto” position </li></ul><ul><li>Batteries’ voltage reading acceptable </li></ul><ul><li>Batteries’ charging current readings acceptable </li></ul><ul><li>All pilot light indications – normal </li></ul><ul><li>Crankcase oil level </li></ul>
  6. 6. FIRE PUMPS - INSPECTION, TESTING & MAINTENANCE <ul><li>INSPECTIONS: </li></ul><ul><li>WEEKLY: </li></ul><ul><li>Check diesel engine system condition: </li></ul><ul><li>Cooling water level </li></ul><ul><li>Battery electrolyte level </li></ul><ul><li>Battery terminals free of corrossion </li></ul>
  7. 7. FIRE PUMPS - INSPECTION, TESTING & MAINTENANCE <ul><li>TESTS: </li></ul><ul><li>WEEKLY: - TEST FIRE PUMPS WITHOUT FLOWING WATER. </li></ul><ul><li>Start the pump automatically. </li></ul><ul><li>Electric pump – run for minimum 10 minutes. </li></ul><ul><li>Diesel pump – run for minimum 30 minutes. </li></ul><ul><li>Check pump circulation relief valve is discharging water. </li></ul><ul><li>While pump is running: </li></ul><ul><li>Record pump suction & discharge gauge readings. </li></ul><ul><li>Check pump packing glands for slight discharge – adjust if necessary. </li></ul>
  8. 8. FIRE PUMPS - INSPECTION, TESTING & MAINTENANCE <ul><li>TESTS: </li></ul><ul><li>WEEKLY: - TEST FIRE PUMPS WITHOUT FLOWING WATER. </li></ul><ul><li>Check for unusual noise or vibration. </li></ul><ul><li>Check packing boxes, bearings & pump casing for overheating. </li></ul><ul><li>Record pump start pressure. </li></ul><ul><li>Electrical Systems: </li></ul><ul><li>Observe time for motor to accelerate to full speed. </li></ul><ul><li>Record the time controller is on first step (for reduced voltage or reduced current starting). </li></ul>
  9. 9. FIRE PUMPS - INSPECTION, TESTING & MAINTENANCE <ul><li>TESTS: </li></ul><ul><li>WEEKLY: - TEST FIRE PUMPS WITHOUT FLOWING WATER. </li></ul><ul><li>Diesel Engine system: </li></ul><ul><li>Observe time for engine to crank </li></ul><ul><li>Observe time for engine to reach running speed </li></ul><ul><li>Observe engine oil pressure gauge, speed indicator, water & oil temperature indicators periodically while engine is running </li></ul><ul><li>Record any abnormalities </li></ul><ul><li>Check heat exchanger for cooling water flow </li></ul>
