The present application relates to a kind of multi-test bench railway vehicle test data integrated management system, belong to railway vehicle test data management technical field.The data acquisition module of the system is based on adaptive matching mechanism obtains multi-test bench data and completes local pre-processing;Data processing module constructs data correlation rule, generates dynamic cross-test bench data correlation atlas, realizes multi-source data fusion and value-driven storage scheduling by hierarchical fusion strategy;Core management module generates test task scheduling scheme and completes priority adjustment, constructs digital twin mapping and generates whole-process traceability link;Interactive collaboration module generates adaptive data display scheme, pushes abnormal early warning and completes field operation interaction.The present application solves the problems of existing multi-test bench data integration, scattered management and poor traceability, realizes the standardization and intelligent control of whole-process railway vehicle test, and improves the test efficiency and data management reliability.

This utility model provides an online rotary descaling nozzle assembly for shell-and-tube heat exchangers, relating to the field of descaling nozzles. It includes a spray cover and an inlet cylinder. A pressure cylinder is screwed onto the outer side of the inlet cylinder, a tension spring is welded to the top of the inlet cylinder, a shielding shell is welded to the outer side of the inlet cylinder, and a telescopic cylinder is slidably connected to the inner side of the inlet cylinder. A ring plate is welded to the bottom end of the telescopic cylinder, a rotating cylinder is rotatably connected to the inner side of the telescopic cylinder, a propeller plate is welded to the inner side of the rotating cylinder, and a guide plate is welded to the inner side of the telescopic cylinder. A rotating cylinder is welded to the bottom end of the spray cover. The arrangement of the spray cover, tension spring, telescopic cylinder, and rotating cylinder avoids the problem of traditional nozzles being easily clogged by external scale due to exposed nozzles, ensuring that the nozzle assembly can smoothly advance inward along the tube bundle. This solves the problems of traditional rotary descaling nozzles where the head position cannot break through scale blockages in the tube bundle and the exposed nozzle structure being easily clogged by external scale.
