Analysis on reliability standard system of scraper chain based on whole life cycle

Aimed at the current situation that the reliability was too low to lead to frequent problems reducing the boot rate of fully-mechanized coal mining face, an d the lack of common standards and methods to guide the implementation of relability, relibility standard concept and scraper chain based on whole life cycle was put forward. The three main problems existing in the current standard system construction were comprehensively analysed. The main reliability works of scraper chain on d esign, manufacturing, transportation and storage, maintenance were tracked and guided. The standards such as product standards, test standards and method standar ds were determined to regularize the reliability works. The reliability standard system on whole life cycle of scraper chain was constructed, which had a certain guiding significance on the improvement of reliability and precaution of problems.
