Innovative Cooling Solution Overcomes Challenges in Aerospace Valve Testing

In the world of aerospace testing, precision and reliability are paramount. One crucial component in this process is the hydraulic power unit (HPU), a complex system designed to test aerospace valves. Hydraulic Supply Company received a request from a customer who faced a unique set of challenges that affected the design and implementation of their custom solution.

Challenges:

The HPU is a critical part of the test stand, responsible for running on a non-standard hydraulic fluid with low viscosity. To ensure optimal performance, the fluid temperature must be kept below 125°F. This requirement posed a significant challenge, particularly in an outdoor setting where the ambient temperature can soar to 95°F. Our team also faced limitations on the size of the entire assembly, influencing the design process.

Key Specifications:

• Powerful Main Electric Motor: The HPU boasts a main electric motor with an impressive 150 HP, providing the necessary power for aerospace valve testing.
• Large Cooler: To tackle the challenge of keeping the hydraulic fluid temperature below 125°F, a substantial cooler was incorporated into the design. This cooler plays a crucial role, especially in the scorching Florida heat.
• Generous Fluid Capacity: With an 80-gallon tank, the HPU ensures an ample supply of hydraulic fluid for the testing process.
• High-Pressure Performance: The system can flow 50 gallons per minute (GPM) at approximately 5000 psi, meeting the demanding requirements of aerospace valve testing.
• Efficient Kidney Loop Motor: A 7.5 HP kidney loop motor with a 30 GPM pump operates at minimal pressure, contributing to the overall efficiency of the system.

Innovative Cooling Solution:

The standout feature of this HPU solution lies in its innovative cooling system. Given the challenging ambient conditions in Ft. Lauderdale, the team devised a cooling mechanism that efficiently maintains the hydraulic fluid temperature within the required range.

The cooler, strategically integrated into the design, dissipates heat effectively, preventing overheating even in high-temperature environments. This not only ensures the proper functioning of the pumps but also extends the lifespan of critical components, contributing to the overall reliability of the aerospace valve testing process.

Hydraulic Supply Company was able to overcome the challenges related to fluid temperature, ambient conditions, and size limitations, to create a custom solution that showcases a commitment to excellence. This HPU not only meets but exceeds the demanding specifications required for our customer’s continued success, providing a robust and reliable solution for their future endeavors.
