PT400 Vibration Demo Equipment

PT400 adopts ABB small three-phase asynchronous motor driven by belt pulley, combined with frequency converter to adjust the speed. The belt drives the rotor components, and different types of bearings can be selected to verify the frequency characteristics of bearing defects at different speeds. It can also perform fault gear testing, belt drive testing, rotor dynamic balance testing, start stop testing, and shaft friction testing. It can be tested separately or in combination with various defects in a safe and controllable environment. As an innovative experimental platform for studying the fault characteristics of rotating machinery, it fully meets the extensive needs of teaching simulation and scientific research users.

The test bench mainly consists of three-phase asynchronous motors, frequency converters, double support bearings, dynamic balancing rotor discs, shafts, transmission gear sets, belts and tensioners, shock-absorbing foundation bases, bending shaft components, etc.

•Fault bearing simulation: bearing inner race fault, bearing outer race fault, bearing rolling element fault, bearing cage fault, and comprehensive bearing fault.

•Gear fault simulation: missing gear, broken gear, wear, cracks.

•Belt wear fault simulation and rotor dynamic balancing.

•Common mechanical failures: mechanical looseness, shaft bending, and misalignment during testing.

•Identification of bearing fault frequency at different speeds.

•Test bench start stop test.
