Abstract

The invention discloses a method for reducing the failure number of a coal ash weight-loss weigher, and the method comprises the steps: employing a new logic controller and a peripheral device, wherein the mean free error time of the logic controller is more than ten years; employing the logic controller capable of achieving on-line query, compiling a control program, and achieving the on-line controlling of a program control process through the logic controller; adding a function of fault display in the program, and carrying out fault processing timely according to the fault information. The method can iron out the defects in the prior art that the number of functions is low, the structure is not reasonable and the service life of equipment is short, so as to achieve the advantages that the number of functions is large, the structure is reasonable, and the service life of the equipment is long.

Description

technical field [0001] The invention relates to the technical field of cement processing, in particular to a method for reducing the failure times of a fly ash weight loss scale. Background technique [0002] The cement milling coal ash loss-in-weight scale of our company's branch factory has a high frequency of failures in recent years. The investigation found that the controller of the cement milling coal ash weight-loss scale failed, which caused the loss-in-weight scale to lose control and caused the operator to ensure the cement production. quality and stop cement production. From January to June 2013, the failure frequency of the weightlessness scale was 6 times / month. [0003] In order to better analyze the failure and find the main reason for the failure of the weightlessness scale, we made statistics on several causes of the failure of the weightlessness scale and drew a fault arrangement diagram according to the statistical table. [0004] Weight loss scale failu...
