PT100 bearing fault diagnosis simulation experiment platform
Function description
This fault diagnosis simulation experiment platform consists of common bearing faults. It can study and study various vibration spectra and demonstrate the unique vibration characteristics of related products.
When performing preventive maintenance tasks on industrial rotating equipment, maintenance personnel often encounter the detection of bearing faults. Due to the fault type of each component in any ball bearing, it can usually be diagnosed based on the vibration frequency. By measuring the vibration spectrum, changes over time, it helps to determine the remaining life of the bearing, as well as the criteria for its eventual replacement.
Five industrial-grade rolling bearings are available, which are interchangeable with various standard bearings in use. Each bearing is modified, carefully repaired, and a specific fault is created by hand, which can be detected using spectrum analysis technology.
Each bearing can be disassembled and the fault types realized are inner ring, outer ring, rolling element, and cage. Single faults, as well as combined combined faults can be realized, and the bearings are carefully reassembled to make them indistinguishable from the standard bearings provided.

PT300 Dynamic Balancing Shaft Alignment Simulation Platform
Functional Description
This simulation platform is designed to learn dynamic imbalance and misalignment faults.
This simulation platform, which generates vibrations according to the degree of defects, can simulate the vibration phenomena caused by imbalance and misalignment. In addition, it is also an ideal choice for training balancing and shaft alignment methods to correct imbalance and misalignment faults.
Product Features
To achieve imbalance, three holes are drilled in the 154mm disc so that any unbalanced mass can be added at the desired position.
The misalignment mechanism is designed to set defects without disassembling the machine by moving the motor freely back and forth.
PT300 is the best educational simulation platform for learning imbalance and misalignment, as well as calibration methods.

PT500 gearbox fault diagnosis simulation experiment platform
Functional description
According to teaching requirements, a specially developed one is used to simulate industrial production gearboxes. It consists of a motor, parallel shaft gearbox, planetary gears, low speed bearings and magnetic brakes. All functions of the PT500 can be used to study gearbox dynamics and acoustic characteristics, reliability monitoring, vibration-based diagnostic technology, lubrication status or wear particle analysis.
Product Features
The effects of defects such as surface wear, broken teeth and pitting can be seen in spur or helical gears. Rolling element bearing defects such as inner ring, outer ring and rolling element damage can also be included. Clearance adjustment allows clearance studies. Increasing the amount of clearance has no other major effects except for increased noise and rotational clearance, but if the tooth clearance is reduced, it may seize and cause increased operating temperature. Different types of defects can be added to the gearbox one by one, or added simultaneously to study defect interactions. The speed can be controlled by the speed regulator to study the effect of speed changes on the damaged gearbox and the changing characteristics of the vibration spectrum.
Gears can be moved laterally to mesh with other faulty gears
Can accommodate spur or helical gears
Can easily draw conclusions to study the effects of damaged and worn gears on vibration characteristics
Can adjust the backlash by moving the bearing seat to provide the required clearance

√Introduction
Valenian provides a variety of data acquisition systems
The device will provide machinery fault simulation. Users can install fault modules on the small rotating machine and view the vibration caused by a specific defect. It will allow users to study the signatures of common machinery faults without compromising critical equipment.
VALENIAN Machine fault simulator you're describing is a highly advanced and versatile tool for industrial and research applications. It's designed to simulate over 30 different types of industrial machine faults, making it invaluable for research and development teams working on technical products. By simulating faults in various moving machinery components, such as gearboxes and bearings, researchers can study the vibrational signature patterns associated with different conditions. This capability is crucial for understanding how machinery behaves under various states of disrepair or malfunction.
The ability to install both healthy and faulty parts simultaneously within the same device offers a significant advantage. It allows for direct comparison between normal and abnormal operation conditions, facilitating a deeper understanding of how different faults impact machinery performance. This feature is especially beneficial for developing predictive maintenance strategies, improving machine design for greater resilience, and enhancing diagnostic tools.
Such a fault simulator serves several key purposes:Condition monitoring (or, colloquially, CM) is the process of monitoring a parameter of condition in machinery (vibration, temperature etc.), in order to identify a significant change which is indicative of a developing fault. It is a major component of predictive maintenance. The use of condition monitoring allows maintenance to be scheduled, or other actions to be taken to prevent failure and avoid its consequences. Condition monitoring has a unique benefit in that conditions that would shorten normal lifespan can be addressed before they develop into a major failure. Condition monitoring techniques are normally used on rotating equipment and other machinery (pumps, electric motors, internal combustion engines, presses), while periodic inspection using non-destructive testing techniques and fit for service (FFS) evaluation are used for stationary plant equipment such as steam boilers, piping and heat exchangers. Condition-based predictive maintenance (PdM) is a reliable, cost-effective technique for monitoring and diagnosing machinery faults before they irreversibly damage your machinery and cause breakdowns that threaten to undermine product quality, delivery and overall customer service. Moreover, it can act a primary input for initiating proactive strategies. The efectivenss of any PdM program ultimately depends on how accurately and easily the vibration spectra, waveforms and phase relationships can be analyzed and understood.
Educational Tool: It's an excellent resource for training engineers and technicians, allowing them to gain hands-on experience with machinery faults and their symptoms without the risks associated with actual machine failure.
Research and Development: For teams working on new machinery or improving existing designs, the simulator provides a controlled environment to test and validate innovations, understand failure mechanisms, and refine detection techniques.
Predictive Maintenance Development: By analyzing vibrational signatures and other data from the simulator, developers can improve algorithms and systems designed for predictive maintenance, reducing downtime and extending the lifespan of industrial equipment.
