KEY PERFORMANCE AND FUNCTIONS:

The Governor test stand supports dynamic parameter configuration for speed, pressure, shutdown protection signals, and other critical governor testing requirements. It enables comprehensive testing, including:

‌1. Run-in Test‌: Conducted at speeds specified in the governor's Technical Service Procedure (TSP).

‌2. Pneumatic/AC/DC Motor Speed Setting‌: Calibration trials for pneumatic and motor-driven speed adjustment systems.

3. Speed Range Calibration‌: Configures maximum and minimum speed limits tailored to specific governor models.

4. Static Performance Test‌: Simulates diesel engine no-load conditions to measure static fluctuation rate and droop.

5. Step Speed Change Test‌: Tests sudden speed increases/decreases, recording transient response and stabilization time.

‌6. Load Variation Test‌: Simulates abrupt load application/rejection on diesel engines, evaluating speed deviation and recovery time.

7. Droop Adjustment‌: Sets governor droop during simulated load-change scenarios.

8. Oil Pressure/Temperature Monitoring‌: Real-time measurement and display of operating oil pressure and temperature.
