Recently, the centrifugal pump valve fault teaching experimental platform, custom-developed by Valenian for the School of Mechanical and Vehicle Engineering at Hunan University, has been successfully delivered and put into use. This platform aims to assist universities in teaching and research in the field of fluid machinery and fault diagnosis, and to cultivate high-end engineering and technical talents.
Project background and requirements
The School of Mechanical and Vehicle Engineering at Hunan University boasts a solid research foundation in disciplines such as power engineering, engineering thermophysics, and mechanical engineering. It urgently needs practical teaching equipment capable of simulating real-world faults in industrial settings. The school hopes to introduce a comprehensive experimental platform that can specifically simulate, collect data from, and analyze common faults in centrifugal pumps and their valve systems, in order to support related course experiments, graduation projects, and cutting-edge scientific research projects.
Customized solutions
Based on its mature PT series experimental bench technology, Valenian has tailored this centrifugal pump valve fault teaching experimental bench for Hunan University. The core of this experimental bench is a modular single-stage centrifugal pump system, equipped with a transparent pump casing, allowing for direct observation of internal flow patterns and cavitation phenomena. By integrating a ball valve control system, various fault conditions can be accurately simulated and manually set, such as flow and pressure fluctuations caused by abnormal valve opening, cavitation occurrence, etc.
The platform integrates a multi-channel data acquisition system, pre-equipped with vibration acceleration sensors, pressure sensors, temperature sensors, flowmeters, etc., capable of simultaneously collecting multi-dimensional physical signals such as pump vibration, pipeline pressure, fluid temperature, and flow rate. The accompanying professional analysis software supports various advanced vibration analysis functions such as time-domain waveform, spectral analysis, and waterfall plots, enabling students to extract fault characteristics from the data and gain a deep understanding of the fault mechanism.
Application value and significance
The introduction of this experimental platform closely integrates abstract pump and valve fault theory with specific experimental phenomena and data analysis, effectively addressing the challenges of "invisibility and intangibility" in traditional teaching. It not only serves as a teaching demonstration and hands-on experiment for undergraduate and graduate courses such as "Mechanical Vibration" and "Fault Diagnosis and Predictive Maintenance", but also provides high-quality fault data for research teams to verify and develop new intelligent diagnosis algorithms.
This collaboration represents another successful implementation of the "industry-university-research" integration model by Valenian. The delivery of the customized experimental platform has significantly enhanced the teaching and research capabilities of Hunan University in the field of rotating machinery condition monitoring and fault diagnosis, providing strong hardware support for cultivating innovative talents capable of solving complex engineering problems.
