Step (3): judge and get rid of LOAD CELLS abnormal failure: install link code in Weighing feeder link code installation place, open Weighing feeder, observe the instant flow rate value of Weighing feeder instrument display, the instant flow rate value that theoretical instant flow rate value and instrument show is contrasted, if the two unanimously, can determine that LOAD CELLS is normal, perform step (4); If the two is inconsistent, then can determine that LOAD CELLS is abnormal, the fault of eliminating LOAD CELLS exception of taking measures, then performs step (4);
Step (4): judge and get rid of frequency converter abnormal failure: install link code in Weighing feeder link code installation place, open Weighing feeder, adjustment Weighing feeder frequency converter frequency conversion knob, whether running velocity and the instant flow rate value of observing instrument display change, if running velocity and instant flow rate value change, can determine that frequency converter is normal, perform step (5); If running velocity and instant flow rate value do not change, can determine that frequency converter is abnormal, the fault of eliminating frequency converter exception of taking measures, then performs step (5);
Step (5): judge and get rid of Weighing feeder instrument abnormal failure: install link code in link code installation place, open Weighing feeder, repeatedly change setting flow value, whether the instant flow rate value of observing instrument display can always fluctuate around setting flow value up and down, if the instant flow rate value of instrument display can always fluctuate around setting flow value up and down, can determine that instrument is normal; If the instant flow rate value of instrument display continues to depart from setting flow value, can determine that instrument is abnormal, the fault of eliminating instrument exception of taking measures.
Further, in step (1), the measure of calibrating zero point is taked to get rid of the fault of Weighing feeder exception at zero point.
Further, in step (2), take instrument to be shown the fault that running velocity is revised as the measure eliminating tachogenerator exception measuring running velocity.
Further, in step (3), the measure of calibrating Weighing feeder instant flow rate value is taked to get rid of the fault of LOAD CELLS exception.
Further, in step (4), the measure changing frequency converter is taked to get rid of the fault of frequency converter exception.
Further, in step (5), the measure changing instrument is taked to get rid of the fault of instrument exception.
Beneficial effect of the present invention is: in conjunction with the principle of work of Weighing feeder, and forbidden the directly related property of the frequency of occurrence of fault cause and each fault cause from various metering, reasonable determination operation step, progressively determines fault cause and trouble-shooting; The inventive method can get rid of the inaccurate fault of Weighing feeder metering fast and effectively, and required Work tool is common common, and implementation process is simple to operation, and plant maintenance personnel just can be made after simple training skillfully to apply; Creating advantage for resuming production rapidly, ensure that steady production and the product design of enterprise.
