Embodiment Construction
[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0040] Such as Figure 1-4 As shown, when the water inlet valve is opened or closed, the reservoir pipeline will generate a transient air pressure shock in the pipeline, and the transient pressure on the pipeline wall will suddenly rise or fall when the transient pressure reaches a certain value. There will be damage such as rupture. In order to study the relationship between the transient pressure on the reservoir pipeline and the length of the distance from ...

The invention discloses a transient pressure data analysis system for a reservoir pipeline. The transient pressure data analysis system comprises a measuring device for measuring transient pressure of the reservoir pipeline and a data analysis center in communication connection with a data output end of the measuring device. The position conversion mechanism changes the position of the transient pressure of the reservoir pipeline measured by the pressure sensing element at the end part of the measurement channel, and the transient pressure data at each position is fed back to the data analysis center to analyze and obtain the transient pressure distance characteristics of the reservoir pipeline, so that the whole device is prevented from being moved to adjust the position of the measurement channel; coherence and effectiveness of measurement data are maintained, so that measurement errors are reduced, and measurement precision is improved.
Description
technical field [0001] The invention relates to the technical field of pipeline pressure measurement, in particular to a reservoir pipeline transient pressure data analysis system and a measurement method. Background technique [0002] When the valve on a long pipeline is suddenly opened or closed suddenly, water hammer will occur, which will cause the pressure in the pipeline to rise and fall suddenly, and when it reaches a certain level, it will cause serious consequences of pipeline bursting, so For the pipelines used on the waterway, the transient characteristics of the pipelines should be tested and studied. [0003] In the current technology, only the pressure detection element is used to measure and place the transient pressure data in a certain position in the pipeline, and the transient pressure data is analyzed and processed to obtain the transient pressure characteristics of the pipeline. In the prior art, the transient pressure of the pipeline is The dynamic pre...
