Metro & EMU Wheelset Bearing Running-in Test Bench
1. Brief introduction:
Our Metro & EMU Wheelset Bearing Running-in Test Bench is a high-performance, reliable testing equipment specially designed for running-in tests of wheelsets used in urban metro, light rail, passenger cars, EMUs and other rail vehicles. It integrates advanced mechanical, hydraulic and electrical control technologies, ensuring comprehensive detection of wheelset performance and providing strong support for the safety and stability of rail transit operation.
2. Core Advantages:
• Foundation-free Installation: No need for special foundation construction, easy to move and replace the installation site, saving time and cost for your workshop layout.
• Wide Adaptability: Adjustable applicable gauge (1000—1676 mm) and compatible with various wheelset specifications (wheel diameter Φ750～920 mm, total length ≤2850 mm, etc.), suitable for multiple rail vehicle types.
• Comprehensive Testing Functions: Supports running-in tests for wheelsets with brake discs and axleboxes, with soft start, speed change, braking functions, and adjustable friction pressure, braking force and running-in time.
• Intelligent Monitoring & Alarm: Equipped with left and right axlebox bearing temperature detection (0～100 ℃, accuracy ±1℃), with over-temperature and over-speed alarm functions to ensure safe operation.
• Intelligent Data Management: Computer display screen shows and stores detection data in real time, which can be output at any time; it has long-term storage and recovery functions of basic data, and can automatically judge whether the running-in is qualified.
• High Safety & Reliability: Equipped with emergency stop function, safety interlock device, short circuit, open circuit and leakage protection devices, ensuring comprehensive protection during equipment operation.
• Easy Operation & Maintenance: Simple and easy-to-understand program, convenient operation and maintenance; the software has functions such as equipment fault self-diagnosis, parameter setting, data management and calibration.
