Usually, the failure of mechanical equipment is related to the running time of the equipment, unless there are special circumstances, such as accidents that cause liquid filling machine equipment failure. Generally, the longer the equipment is running, the greater the chance of failure. This is because with the prolongation of the working time, the equipment is affected by the external environment and the fatigue of its own parts is intensified and accumulated. When the accumulation reaches a certain level, it will appear in an abnormal state until it causes equipment failure.
During the working hours of the equipment, by checking and analyzing the aging condition, fatigue status and working performance of the equipment parts, the possibility of equipment failure is predicted, and corresponding measures are taken on this basis to prolong the service life of the equipment and reduce the This is the basic principle of mechanical equipment failure control.
In order to carry out the fault control analysis of the liquid filling machine, it is necessary to select the appropriate parts as the analysis samples first. Proper sample selection has a crucial impact on the quality of fault control analysis work. The selected components must have a high representativeness, be able to reflect the overall life of the mechanical equipment, and have a direct and close relationship with the operating conditions of the equipment.
The judgment of the remaining life of key parts is based on the statistical analysis of the service life data of a large number of similar parts. Firstly, draw the life curve-reliability curve based on the reliability and service life data of a large number of similar parts, and then find out the service life of the corresponding sample reliability on the curve, so as to calculate the remaining use of key parts based on the working hours that have occurred Life span.
