Hydraulic Motor Test Bench: Precision Validation for Performance & Quality
El Hydraulic Motor Test Bench is a specialized platform designed to evaluate performance parameters, validate design specifications, and ensure the quality of hydraulic motors. It is widely applied in critical fields such as engineering machinery, aeroespacial, marina, and industrial automation. We precisely measure essential metrics including torque, velocidad, fluir, presión, eficiencia, and temperature rise.
System Architecture & Key Components
1. Hydraulic Power System (HPS)
The dedicated HPS provides the high-pressure oil source required to drive the DUT, ensuring stable and reliable testing:
- Includes an oil pump, oil tank, piping, and valve groups.
- Provides a continuous and high-pressure oil source.
2. Dynamic Load Device
Designed to apply precise, controllable dynamic loads to the hydraulic motor output shaft:
- Utilizes an Electric Dynamometer (AC Load).
- Supports **Energy Regenerative (Load Feedback)** modes, recycling power back into the grid, offering high energy efficiency and reduced heat dissipation.
- Achieves dynamic load regulation.
3. Sistema de medición y control
The control hub ensures accuracy, seguridad, and data integrity throughout the test cycle:
- Data Acquisition: Includes sensors for Torque, Velocidad, Pressure, Temperature, and Flow Rate.
- Control Logic: Features a hydraulic control system, dynamometer control system, and specialized test software.
- Protection: Provides real-time monitoring, over-limit alarms, and protection for the entire system.
Comprehensive Performance Validation Projects
The test bench facilitates full characterization of hydraulic motor performance across various operational regimes:
| Proyecto de prueba | Medidas primarias | Valor de ingeniería |
|---|---|---|
| Torque & Speed Mapping | Par de salida, Velocidad, and Power curves. | Defines the motor's operating envelope and compliance with rated specifications. |
| Volumetric & Overall Efficiency | Flow Rate (Input/Output), Pressure Drop, and Overall Efficiency (η). | Crucial for identifying internal leakage and optimizing energy conversion performance. |
| Temperature Rise Test | Rate of temperature rise, steady-state thermal conditions (Oil, Case, Ambient). | Ensures the motor maintains stability during continuous high-load operation. |
| Endurance & Durability | Long-term stability under cyclical loading. | Validates predicted service life and structural reliability. |
| Nvh (Ruido, Vibración, Dureza) | Vibration and Noise levels (dB). | Essential for applications requiring high acoustic quality, such as mobile machinery. |
