A maintenance strategy for a multi-valve cryogenic distribution system

[摘要] Big scientific facilities that use cryogenic technologies usually need to transfer and distribute cooling power from a cryogenic plant to cryogenic users. This requires a cryogenic distribution system which includes a number of valve boxes at the interfaces to the cryomodules and magnet cryostats. Such systems consist of a number of components which can malfunction or get damaged in many ways leading to unwanted shut downs of the entire facility. In order to avoid these problems or mitigate their consequences the cryogenic distribution system should be properly operated and maintained. This requires planning of maintenance works, storing spare parts and ordering some service works. The paper presents a maintenance strategy for a multivalve cryogenic distribution system.
