Two advanced transmission system diagnostic simulators from Valentinian delivered to Lanzhou University of Technology

Recently, two advanced teaching devices from Valentian (Suzhou) Teaching Equipment Co., Ltd. - PT900 Transmission System Diagnosis Simulator and WFD100 Wind Turbine Generator Mechanical Fault Simulator - were officially delivered to Lanzhou University of Technology

Learn. These two devices will help the school take its teaching and research work in related fields such as mechanical fault diagnosis and wind power generation technology to a new level.

PT900 machine vibration simulator is an experimental device used to simulate and study the dynamic characteristics of gearboxes and rotating machinery rotors. It can change the speed and stiffness of rotating machinery by setting different operating conditions. By simulating the operating state of the machine based on quality imbalance, friction or impact conditions of the shaft, and the type of coupling, and using relevant vibration data acquisition systems to observe and record its vibration characteristics, this platform can simulate various common types of vibration faults, such as gearbox fault characteristics (parallel gearbox, helical gearbox, planetary gearbox, etc.), loose platform foundation, rolling bearing faults, oil film vortex/oscillation of dynamic bearings, shaft misalignment faults, etc. Its main components include the basic platform, ABB2.2Kw three-phase asynchronous motor, controllable screen operation, PLC control system, converter drive system, etc. It is equipped with a multi-channel vibration excitation data collector and computer analysis software, and has rich frequency and time domain analysis functions, such as envelope analysis. Road diagram. The frequency spectrum and axial orbit diagram provide strong support for researchers and students to study vibration faults of rotating equipment. At the same time, the platform is equipped with equipment safety emergency stop function and personnel operation safety protection function to ensure safety during use

The WFD100 wind turbine generator machine vibration simulator is a multifunctional experimental platform used to simulate industrial wind turbine generators. Reasonable layout, excellent design, precise machining and assembly tolerances, This platform mainly consists of blade grading (same service motor drive), planetary gearbox, parallel gearbox, and generator. In addition to simulating speed gear faults and abnormal vibrations, it can also simulate common mechanical fault symptoms, detect defects in speed bearings, as well as faults in high-speed planetary gears and parallel gears. Through this platform, users can learn to detect and analyze fault points in wind turbine generators, which can be applied to experts in researching wind turbine generator vibrations, vibration training institutions, and technical personnel in equipment vibration analysis and fault diagnosis departments. Its functions include basic vibration star measurement, optimal selection of vibration sensor positions, research on misalignment effects, discovery and correction of soft lakes, and research on bearing and gear failures. In terms of aspects. The relevant person in charge of Lanzhou University of Technology stated that the delivery of these two devices will greatly enrich the school's teaching and research resources. In terms of teaching, students can gain a more intuitive understanding of the theoretical knowledge of mechanical fault diagnosis and wind power generation technology through practical operation of these devices, and enhance their practical and hands-on abilities; In terms of scientific research, it also provides advanced experimental platforms for teachers and researchers in schools, which helps to carry out more in-depth scientific research projects and promote technological innovation and development in related fields.

Valentian (Suzhou) Teaching Equipment Co., Ltd. has been committed to providing high-quality mechanical rotor fault testing benches, status monitoring and fault diagnosis testing software and hardware products. The delivery of these two devices to Lanzhou University of Technology is also an important measure for the company to support the development of teaching and research in universities. In the future, the two sides are expected to cooperate in more fields and contribute to the cultivation of high-quality professional talents and the promotion of scientific and technological progress together
