The invention discloses a method preventing abnormal charging of a blade charging
machine. The method comprises the steps that data collection is achieved through a PLC; collected pipeline pressure is compared with a theoretical value in a pipeline pressure characteristic curve, wherein the theoretical value is obtained by inquiring a table; if the pipeline pressure is smaller than or larger than the theoretical value, warning information is sent; collected feed liquid flow quantity in a charging
pipe is compared with theoretical flow quantity, wherein the theoretical flow quantity is obtained by inquiring a corresponding table; if the feed liquid flow quantity is lower than the theoretical flow quantity, warning information is sent; collected atomization
steam pressure is compared with a technological requirement value, and warning information is sent if the atomization
steam pressure is smaller than the technological requirement value; after production is finished, the average running frequency of a charging pump is calculated, the average frequency is compared with an ideal area, and warning information is sent if the average frequency is larger than the ideal area; a total
score is calculated, and warning information is sent if the deduction
score is larger than set
score. According to the method preventing abnormal charging of the blade charging
machine, health monitoring of a charging
system of the blade charging
machine is achieved, and therefore
system hidden dangers can be found timely.
