Reason and Solution of Pressure Fluctuation in Boiler Feed Water Pumps

Boiler feed pump is the unit load, steam flow and other thermal capacity to adjust, to determine the boiler feed pump in the automatic situation is normal swing, first determine whether the unit caused by abnormal causes, check the pump in place the sound is normal, or Oxygen water level is normal, the water supply temperature is too high, the boiler feed pump pump cavitation is normal, the work of the filter is blocked, and grease is qualified, the analysis of a pump failure, from its entire system To consider and to exclude them one by one.check out boiler feed water pump price
Boiler feed pump pressure fluctuations of the reasons and solutions:
        1, if the inlet pressure is low, the import filter to block, check the pump is not cavitation, exhaust, the greatest possibility is cavitation or gas tied.
        2, check the inlet level of the pump is too low, whether the filter is blocked, whether the inlet pipe leak, the inlet valve is fully open and so on.
        3, to see if the pump current is stable? Is there any speed with the tachometer? And then look at the pump inlet and outlet of the vacuum gauge and pressure gauge is normal?
        4, if the water pump to the water shortage, check the pump inlet valve, water, whether leaks and so on.
        5, may consider the inlet of the pump with gas (steam) or cavitation, check the inlet or not to the vacuum pump (including spare part of the pump), hot water level is low, condensate temperature is high, and if To the vibration of the words can not rule out the possibility of the pump itself.
        6, if the pump filter plug should be the current increases, the pressure will not fluctuate back and forth, it should be leaked the air.
        8, check the balance plate small sets of aprons is broken or the water gap has changed, should be carefully examined.
        9, if the pump does not use the inverter, the export pressure gauge of the normal fluctuations in the amount of about 0.02 to 0.03 MPa between the export check valve of the heavy hammer, but also with the beating.
