Rubber seal is one of the widely used seals in the filed of mine equipment

whose performance determine the reliability of mine equipment

the length of the storage life of rubber seal decides the maintenance difficulty and cost of mine.Predicting the storage life of rubber seal has big significance for improving the reliability of mine.By analyzing storage failure model and failure mechanisms of the rubber seal

the technology of the accelerated life test principle under the condition of constant temperature

test stress and data processing are studied and the storage life of rubber seal can be predicted within a shorter time.The technical support is provided for deciding the changing period of the mine rubber seal.
