Analysis and Reliability of Automated Towel Cabinet Pipeline Key Equipment based on FMECA and FTA

With the improvement of intelligent life and the improvement of living standard, the hygiene and safety of towel machine will become more and more important. As a member of smart home, it is necessary to make high security requirement and reliability analysis because it is usually in a more enclosed bathroom environment. Based on the analysis of the process characteristics of towel machine equipment and the division of assembly line system, the agreed level is determined. The three main equipment units of the intelligent towel machine, namely towel transport and expansion unit, continuous mixing unit for drying and disinfection and drainage unit, are analyzed by the theory method of unit system failure mode, fault effect and hazard analysis. Based on this, the fault tree of transportation unit is analyzed, the main fault source is found, and the design, manufacture and maintenance opinions are put forward.
