How is the development of a product not perfect, why do you say that there will be some small problems during use, and sometimes it can be avoided during use, so how can everyone calm down for the failure of the fire pump? Follow the small Series, see how some errors are diagnosed!
Fire pump fault diagnosis is usually the key link in the process of fire pump inspection. Several common faults and elimination measures are given below to provide a basis for the diagnosis of fire pump faults.
There is no liquid supply, there is not enough liquid supply, and there is not enough pressure.
(1) The pump has no water or proper exhaust.
Elimination: Check whether the pump casing and the air inlet are completely filled with liquid.
(2) The speed is too low.
Elimination measures: Check whether the motor wiring is correct, the voltage is normal, or the steam pressure of the steam turbine is normal.
(3) The system head is too high.
Elimination measures: Check the system head (especially friction loss).
(4) The suction power is too high.
Elimination measures: Check the existing net head.
