The invention relates to the field of sealing packing, and discloses a plunger packing combination sealing life evaluation method, device, equipment and medium, and the method comprises the steps: installing a to-be-evaluated plunger packing combination to a test bench, and obtaining a target test bench; operating the target test bed under a short-term no-load condition, and detecting a first performance parameter of the plunger packing combination; calculating a first dimensionless index according to the first performance parameter, and detecting a first physical parameter between a plunger and a packing in the plunger and packing combination; and inputting the first dimensionless index and the first physical parameter into a trained BP neural network model to obtain a life prediction value of the plunger packing combination. The problems that according to an existing plunger packing sealing life test method, test parameters are not comprehensive, and an evaluation system is not complete are solved.
