| description | In order to solve the problems of time-consuming, high-cost and poor safety in the purging and ventilation progress test of positive pressure explosion-proof motor, the multi-component fluid theory is introduced to analyze the positive-pressure explosion-proof motor. According to the basic explosion-proof principle and key problems of purging and ventilation progress simulation of positive-pressure explosion-proof motor, the explosion-proof finite element model of the motor is established, and the purging and ventilation progress of the motor is simulated and analyzed by multi-component fluid theory. By controlling the concentration of He (helium), the explosive environment and the purging process of the motor can be achieved, and it can be known whether there is a purging dead angle in the motor by observing the transient concentration of each component, which enhances the safety performance of the motor. Then the accuracy of the simulation is verified by experiments. Finally, based on the observation of the fluid components in the original motor, an optimization scheme of changing the intake pipe is proposed, which can improve the efficiency of purging and enhance the reliability of the motor. |
