Equipment Dynamic Failure Model and Case Study
The running equipment of industrial system may be affected by not only the conditions of the system but the operating state itself,so that the risk of equipment failure was considered as dynamics.During researching the possibility and severity of the failure risk,it is necessary to understand and investigate the dynamic characteristics of equipment failure in the system life cycle.In this article,equipment failure of dynamic risk factors were summed up as a function of failure rate, external load of equipment, and the system structure and system function effect to the severity of risk.A dynamic risk model is put forward.The model was used for cavity-made water system of Jintan underground gas storage, the map of pump dynamic failure risk was drawn out, the situation and reasons of the risk in three typical stages of early,middle,late of making storage and injection gas was recognized.Empirical studies show that the model may be inferred the status and trends of equipment failure risk in the system running cycle,so that the risk may be controled effectively and timely.
