Abstract: The present invention discloses an industrial equipment operation, maintenance and optimization method and system based on a complex network model. The method includes the following steps: obtaining data of all sensors of industrial equipment, and calculating a Spearman correlation coefficient between data of every two of the sensors within the same time period; using each sensor as a node, and using the Spearman correlation coefficient as a weight of a network edge, to construct a fully connected weighted network; and obtaining, when an adjustment instruction for a target feature is received, a currently optimal parameter adjustment path of the target feature based on the fully connected weighted network. In the present invention, production equipment in reality is digitized to construct a complex network oriented to industrial big data. An optimal path for equipment parameter tuning may be found by using the network, thereby reducing dependence of an enterprise on a domain expert.

Abstract: It is a kind of multistage wave rotor refrigerator which could be used in the field of gas expansion refrigeration. The refrigerator is mainly composed of a casing, a left end cover, a right end cover, a wave rotor, a central shaft, a high pressure inlet nozzle, a medium pressure outlet nozzle and a drive mechanism. Within the structure of the refrigerator, 2-8 times unsteady expansion of gas could get realized, which improves the refrigeration efficiency under large pressure ratio. Extending the structure of the refrigerator and changing the structure of end cover could help realize multistage expansion refrigeration of gas. The double opening structure of oscillation tubes could help the refrigerator work regularly with high moisture content of gas. This refrigerator is a gas expansion refrigeration device that uses moving unsteady pressure waves in oscillation tubes to realize the separation of the heat and cold of gas.
