Abstract:In order to improve the stability of the rack cushion paper machine and protect the quality of the MCC rack,the method of fault tree analysis (FTA) is used to establish a fault tree model with the top event of paper deviating or paper shredding of rack cushion paper machine,find out the logical relationship of the bottom event that caused the failure and formulate corresponding measures to eliminate the fault of rack cushion paper machine.It is pointed out that using the method of FTA to find out each bottom event which leads to the top event will lead to the fault of rack cushion paper machine.The bottom events of poor guiding performance of paper-guiding mechanism and inaccurate real-time demand length of paper-feeding are the most,it can be eliminated by optimizing the design of paper-guiding mechanism,improving the manufacturing accuracy and the accuracy of encoder and stepping motor,and optimizing the electronic control program.The method of FTA can help enterprise personnel to understand and master the failure mode and failure reason of the rack cushion paper machine,according to this,the measures are formulated,which can improve the quality of the rack cushion paper machine and the efficiency of the rack in punching and quenching of the MCC,and reduce the production cost.
Key Words:rack cushion paper machine;MCC;rack;FTA method;fault tree;top event;bottom event
