Mid-Size Body Aircraft Diesel Driven Hydraulic Test Stand

Part Number: BF120-1D

Long Description:

The Mid-Size Body Aircraft Diesel Driven Hydraulic Test Stand (BF120-1D), manufactured by Hydraulics International, Inc. (HII), is a highly efficient and versatile ground support system engineered specifically to service, test, and maintain hydraulic systems of medium-sized commercial and military aircraft. Powered by a robust diesel engine, the BF120-1D provides dependable, independent hydraulic power essential for aircraft maintenance facilities, particularly in environments lacking readily available electrical power sources or in scenarios where portability and autonomy are critical.

Designed with reliability, durability, and performance in mind, this hydraulic test stand is capable of delivering a significant hydraulic flow rate of up to 16 gallons per minute (GPM) at pressures of 3000 pounds per square inch (PSI). Additionally, it can operate effectively at 10 GPM at higher pressures up to 4500 PSI, offering flexibility for various testing and maintenance requirements. The system’s flow rate and pressure capabilities are sufficient for comprehensive operational tests and servicing of diverse hydraulic components, including pumps, motors, actuators, valves, and accumulators.

The BF120-1D features dual independent hydraulic circuits, enabling technicians to simultaneously test separate hydraulic systems or multiple components at varying pressure and flow settings. This dual-system configuration enhances operational efficiency, significantly reducing downtime and streamlining maintenance tasks, ultimately improving turnaround times and aircraft readiness.

Integral to the unit is a high-performance filtration system designed to maintain the purity and cleanliness of the hydraulic fluid. The test stand incorporates high-pressure filters rated at approximately 2-3 microns and a low-pressure return line filter rated at 25 microns. These filtration components effectively eliminate contaminants, moisture, particulates, and air bubbles, thus ensuring optimal hydraulic fluid quality. Maintaining fluid cleanliness at the highest aviation standards is critical to extending component service life and reducing the risk of hydraulic system failures.

The stainless-steel hydraulic fluid reservoir, boasting a total capacity of 120 liters (operative capacity), is engineered for resilience and longevity. It features convenient inspection ports, fluid-level sight indicators, a drain valve, and easy-access filling points, significantly simplifying maintenance procedures and ensuring quick servicing.

For operator convenience, the BF120-1D incorporates comprehensive instrumentation, including high-accuracy pressure gauges, digital flow meters, fluid temperature indicators, and contamination monitoring devices. These instruments provide real-time diagnostic data, facilitating precise monitoring and efficient troubleshooting. Operators can quickly assess system performance, detect anomalies, and implement corrective actions immediately.

Furthermore, the unit is designed for exceptional mobility and ease of handling within aviation maintenance environments. Its rugged frame construction, coupled with a compact, maneuverable chassis, enables rapid and effortless repositioning within hangars or across maintenance facilities, ensuring operational flexibility and convenience.

Applications:

The BF120-1D is ideally suited for:

• Routine Hydraulic System Maintenance: Comprehensive testing and servicing of mid-size aircraft and helicopter hydraulic systems.

• Component Testing and Certification: Validation and certification of hydraulic pumps, motors, actuators, and valves, ensuring compliance with strict aerospace quality standards.

• Hydraulic Fluid Conditioning and Flushing: Regular flushing and fluid purification to extend the operational life of aircraft hydraulic components.

• Field Operations and Remote Maintenance: Diesel-powered operation ensures self-contained capability, ideal for operations in remote or austere environments where electrical infrastructure may be limited.
