An integrated experimental module for hydraulic orifice and/or crevice high and low temperature fluid mechanics experiments

Abstract

The invention provides an integrated experiment module used for a hydraulic high-low temperature fluid mechanics experiment of a hydraulic hole and / or gap and an automatic measurement and control system employing the integrated experiment module. The module employs the principle of integrated design, and enables an oil liquid, an oil supply mechanism, a tested valve and a sensor to be integrated.The whole module can be placed in a high-low temperature box, thereby solving a problem of the temperature control of the tested valve conveniently, effectively and accurately. The tested valve comprises a tested hydraulic hole and / or gap, and can be prepared and replaced according to different experiment requirements. The system provided by the invention can automatically control the temperatureand oil supply of the tested valve, also can automatically test the oil temperature, pressure and flow of the tested valve, and carries out the postprocessing, storage and outputting of the test data.

Description

technical field [0001] The invention relates to an integrated experiment module and an automatic measurement and control system capable of performing fluid mechanics experiments in high and low temperature environments for common hydraulic orifices and / or gaps, and belongs to the technical fields of hydraulic experiment equipment and hydraulic experiments. Background technique [0002] With the development of modern society, human beings increasingly require vehicles, mobile machinery, aerospace, ocean engineering and other high-end equipment to be able to serve in extreme high, low temperature or high and low temperature environments, and hydraulic technology is the key technology driven by these equipment Therefore, high requirements are placed on the performance of various hydraulic components in high-end equipment. For example: modern high-speed rail may be required to run from an alpine region (below -40°C) to a high-temperature region within one day, then core componen...

AI Technical Summary

Problems solved by technology

Because at low temperatures, such as below -30°C, general hydraulic pumps can no longer effectively absorb oil, and many hydraulic valves and pipelines cannot work normally, let alone carry out relevant experiments effectively and accurately; moreover, in high and low temperature experiments , it is neither convenient nor accurate to control the temperature of the hydraulic oil of the entire hydraulic system
