You May Want To Seek Out The Hydraulic Authority To Solve Challenges Such As Leaking Power Units

Ray McCann, Sales Engineer
The Hope Group

Every day, Hydraulic specialists at The Hope Group solve design and construction problems for complex hydraulic power units, lubrication units, and pneumatic systems.

In a recent blog post, Ted Amling, Sr. Project Engineer at Parker Tube Fittings Division wrote about how a leaking test stand was repaired by actually lengthening the connection between two ports rather than keeping the original short, straight connection. It takes a lot of experience and expertise with hydraulics to understand that the leak-free distance between two points may not be the short route.

As the Hydraulic Authority in New England, The Hope Group represents Parker hydraulic components for its customers and specializes in the design and build of complex hydraulic power units for a wide range of commercial and industrial customers in the food and beverage, life science, transportation, machine tool, defense, and marine/mobile markets.

The example that Ted Amling wrote about was an expensive test stand intended to test transmission systems, which was leaking. He described that it, “involved two ports directly across from each other – a very short distance between them – connected by a straight routing using a large, two-inch OD line.” He described that everything was tight, but it kept leaking. It turns out, according to Ambling, vibration along the line caused the joints to loosen over time.

So, the irony of the situation was that to solve the problem, a u-bend was added to the tubing, including elbow fittings, which provided enough give in the line to cure the leak. The longer route was the leak-free route. Ambling described that planning tube line routing, “is a time investment, but it can have a big ROI, especially for complex systems. It’s in cases like this, which have complex design and build requirements that The Hope Group engineers, technicians, and specialists can make a difference for its customers.
