PT500mini vibration demonstration equipment delivered to Zhengzhou Shengda Information Engineering College

Recently, an advanced PT500mini vibration demonstration device was officially delivered to Zhengzhou Shengda Information Engineering College. The arrival of this training platform will inject new vitality into the teaching and research work of the college in mechanical engineering, automation and other related majors.

The PT500mini vibration demonstration device has high functionality and flexibility. It can simulate various practical machine faults, including gear faults, rolling bearing faults, and impeller rotor faults. In terms of gear fault simulation, the small gear has double row teeth and can be directly shifted to the faulty gear to achieve different fault scenarios such as missing teeth, broken teeth, cracks, and wear (increased tooth clearance). Teachers and students in the college can choose one type of fault for experimentation according to teaching and research needs. If multiple types of faults are needed, open the gearbox and replace the gear. The fault simulation of rolling bearings adopts the PH205 model, which can simulate faults in rolling elements, cages, inner rings, outer rings, and other parts. By quickly replacing bearings with bearing seat installation units, it is easy to switch to healthy bearings and restore normal operation. For impeller rotor faults, this training platform can simulate an unbalanced state by installing balance weights at any angle on the rotor to conduct dynamic balance tests. What is particularly prominent is that the preparation time for simulating the switching of all the above faults is extremely short, and only the Allen wrench and adjustable wrench are needed to complete the fault setting of the test bench.

This training platform adopts ABB small three-phase asynchronous motors, which are directly driven by couplings and adjusted by frequency converters. At the same time, the adjustable magnetic powder load can add different testing loads to the testing platform. This configuration allows college teachers and students to choose bearings with different types of faults and deeply verify the frequency characteristics of bearing defects at different speeds. In addition, fault gear testing, impeller blade testing, rotor dynamic balance testing, start stop testing, shaft friction testing, etc. can be conducted separately or in combination with various defects for diversified experiments in a safe and controllable environment.

As an innovative experimental platform, the PT500mini vibration demonstration device can fully meet the extensive needs of teaching simulation and scientific research users in the college. In terms of teaching, it will provide intuitive and realistic practical scenarios for courses related to maintenance and equipment status monitoring, which will help improve students' practical operation ability and fault diagnosis skills. For scientific research work, this training platform can provide support for early training of professional fault diagnosis personnel, and also provide a powerful tool for studying the characteristics of rotating machinery faults, helping the college to carry out more in-depth research in related fields.

The delivery of the PT500mini vibration demonstration equipment is an important measure for Zhengzhou Shengda Information Engineering College in practical teaching and scientific research innovation. It is expected to further improve the education and teaching quality and scientific research level of related majors in the college, laying a solid foundation for cultivating high-quality professional talents and promoting discipline development.
