How do you ensure accumulator safety?
Accumulators are pressurized vessels that hold fluid under pressure. This stored energy can be called upon to boost energy to a system when needed, then recharged to store it again. This stored energy can be dangerous; proper care should be taken to ensure pressure and temperatures are kept under control. Several small yet critical accessories…
Storage and cleaning of elastomer seals
Elastomer seals are built to handle a wide range of demanding hydraulic and pneumatic applications. A seal’s design and its material properties are two keys to lasting performance. The engineers at Parker Hannifin’s Engineered Materials Group in Germany also offer some important recommendations on how to store, handle and clean seals prior to use. Dr. […]
Building a world-class hydraulic pump
Understanding what can go wrong ensures that hydraulic pumps get built right. Every OEM says it wants quality, but the reality is that machine builders can choose from countless hydraulic components that vary widely in performance and price—from cheap, “throw-away” parts to high-quality and, more-expensive, products that are built to last. How does an engineer […]
How to achieve safety in industrial hydraulics
The history of labor unions dates to the late 1800s when employees worked in often wretched conditions with little or no regard paid by employers for safety, fair wages and reasonable workaday hours. It’s hard to argue the level of productivity achieved prior to the amelioration of unions, and some would wager the great railroads…
Innovative pneumatics are realized in subsystem design
Innovation in pneumatics is often found in the way components are put together to create subsystems, instead of within the components. Contributed by Pat Phillips, PE, Product Manager for AutomationDirect, Fluid Power and Mechanical Product Div. Pneumatics have been used in industrial machines and manufacturing plants and facilities for decades, so most of the […]
What hydraulic pump type is best for my HPU design?
By Josh Cosford, Contributing Editor The type of pump you choose for your power unit affects the nature of the HPU build. Pump choice boils down to cost, complexity and performance. There are three major types of pumps: the gear pump, the vane pump and the piston pump. There are other, less common pumps, but […]
Update from AICD: We can use our brains better
