Abstract

The invention relates to an accurate prediction and calculation method for the service life of a rubber sealing product. The method comprises the following steps of: preparing a rubber material into a standard rubber test block and a finished product sealing element; measuring rubber performance indexes; finding out an aging critical value of the rubber material; calculating aging reaction time t through a formula; and calculating the lower limit ages of the expected service life under a given confidence level (1-c) through a formula. According to the method, the initial assembly compression ratio and the use environment temperature condition of the rubber material product are considered, the expected service life of the rubber material product is calculated, a basis is provided for pipeline design, the pipeline operation efficiency is improved, the pipeline water conveying performance is guaranteed, the replacement of the rubber material product is reduced, and the product utilization rate is increased.

Description

technical field [0001] The invention belongs to the technical field of predicting and calculating the service life of material products, and in particular relates to an accurate predicting and calculating method for the service life of rubber sealing products. Background technique [0002] There are various types of rubber products and a long history of use. Among them, a class of important products are used in the sealing parts of mechanical products, which play the role of sealing connections. Products such as rubber sealing rings and rubber gaskets are widely used in aerospace military industry, power machinery, pipeline transportation and other industries. [0003] With the extensive application of rubber seals, their service life has become an issue of increasing concern. Rubber seals are affected by various factors in their use environment, such as oxygen, sunlight, wind, ozone molecules in the atmosphere, water and oil and other working media and their temperature, ...
