                  Power plant condensate pump too much current swing what are the reasons?

                  Current changes of the condensate pump and cooling tower water pool; Current changes of the condensate pump general level and the condenser heat coagulation related; Changes in general and boiler feed water pump current load and the steam drum pressure.

                  Low water pressure atresia of low-pressure by-pass door protection: use the original circuit and constant value. At the beginning of the unit using a variable frequency operation, deaerator C - 1 can be close to a certain position, make the condensate has enough pressure to ensure the normal operation of the low side. Low water level of the condensate pump protection: the original circuit and constant value.

                  Condensate pump is mainly for coal-fired power plants conveying condensed water, can also be used in medium similar to those of condensed water and other six traffic and unit type, such as air cooling, back pressure is not needed.

                  Condensate pump is one of the important auxiliary equipment, power plant energy consumption of electricity in the whole factory occupies an important share. Power generation in the load change is significant, but when generating unit load changes, but keep the rated speed of the condensate pump running, rely on regulating valve opening to adjust the size of the water, the throttling loss is big, motor consumes a lot of electricity. After changed to variable frequency speed regulation, when with load change, speed closed loop control of condensate pump frequency control of motor speed system, adjust the opening of the valve, no longer condensate pump motor will run under low current and low frequency, significant energy saving space, is expected to reach 50%.
