YYQ-8000A Belt Drive Dynamic Balancing Machine for Generator Rotors

The YYQ-8000A series is a universal hard-bearing dynamic balancing machine strictly manufactured according to the GB/T4201-2006 standard. It utilizes roller supports and belt drive transmission, paired with an industrial control computer for advanced data processing. The 19-inch LCD screen displays vector graphics, waveforms, unbalance amounts, phase angles, and real-time speeds simultaneously. Powered by a 15kw variable frequency motor, it supports stepless speed regulation from 100-1000 r/min. It is capable of both single-plane and dual-plane balancing, making it the ideal calibration equipment for heavy-duty rotary machinery.

Application Scenarios & FAQ

• Application Scenarios:
  Widely used in power generation (generator rotors), industrial fluid equipment (water pump impellers, fan impellers), and motor manufacturing industries for high-precision dynamic balancing of regular cylindrical rotors with large rotation diameters and high damping.

• FAQ:

• Q: How wear-resistant are the support rollers?
  A: The rollers are made of GCr15 bearing steel, processed through high-frequency quenching (hardness over HRC55), grinding, lapping, and demagnetization. Paired with RZ5 precision bearings, they form a wide-line contact with the workpiece, offering extremely high wear resistance while protecting the workpiece surface.

• Q: What should I do if the software or sensors fail?
  A: The software features a comprehensive self-diagnostic system. By generating waveform charts through the PC and sensor/cable inspection functions, you can visually determine if there is a fault. If you cannot identify the issue yourself, you can simply send the waveform data to us for rapid troubleshooting assistance.

• Q: How can I export the measurement results?
  A: The software supports a direct connection to a printer, allowing you to print a complete measurement report for a single test or all tests conducted that day. It also features a USB interface for unlimited external data storage.

• Superior Bed Structure: Adopts two 3-meter-long HT250 integral cast iron bed sections with T-type parallel guideways, processed and ground by a large gantry milling machine for exceptional flatness and mechanical precision.

• High-Rigidity Swing Frame: The split-type swing frame is cast from QT450 ductile iron. Its performance surpasses welded frames, providing high natural frequency and guaranteeing absolute measurement accuracy.

• Smart Diagnostics & Protection: The software includes a self-diagnostic function that checks the industrial PC, sensors, and cables via waveform analysis for rapid fault location. Safety guards are equipped on both sides to prevent workpiece bouncing caused by massive unbalances.

• Multi-dimensional System Support: Supports ABC calculation methods (6 support calculation types) and influence coefficient methods. It includes a built-in ISO standard permissible unbalance calculator to automatically determine the allowed residual unbalance in grams based on rotor parameters.
