Fire Pump Pressure Shortage Do
Cause analysis and solution to the fire pump pressure is low:
1, pump no water or no suitable exhaust
Solution: check that the pump and inlet piping is filled full with liquid.
2, the speed is too low
Solution: check for proper electrical wiring, voltage is normal or Turbo steam pressure is normal.
3, the system head too high
Solution: check the system head (especially the friction losses).
4, suction lift too high
Solution: check the existing net pressure head (inlet piping is too small or too long will cause a lot of friction losses).
5, impeller or pipeline plug
Solution: check for obstructions.
6, the direction of rotation is wrong
Solution: check the direction of rotation.
