Each month Fluid Power Journal brings you an industry problem with a solution the following month.
Test Your Skills: Understand the Application of Hydrostatic Systems
The typical hydrostatic transmission consists of a closed circuit where a pump provides flow to a hydraulic motor without the use of directional valves. The …
Test Your Skills: The Difference Between Isothermal and Adiabatic Conditions
Hydraulic accumulators use weights, springs, or gas pressure to generate the precharge force against the fluid that is stored for use in the system. …
Test Your Skills: Calculate the Kinetic Energy
It is common practice to position shock absorbers to cushion loads attached to air cylinders, rather than to subject the air cylinders to shock loading …
Test Your Skills: Size a Rotary Actuator
Rotary actuators are used to provide a partial rotation or pivoting action to a component where the space available is not practical for a cylinder and …
Test Your Skills: Understand the Application of Regenerative Circuits
Regeneration is a general term that describes what happens when exhausting hydraulic fluid from the rod side of an actuator is directed back into the pressure …
Test Your Skills: Electric Flow Control Devices
Flow control valves influence actuator speeds in a fluid power system. Increasing or decreasing the opening to flow at a throttling point adjusts the flow to …
Understanding the Function of Accumulators
Accumulators come in a variety of forms and have important functions in many hydraulic circuits. They are used to store or absorb hydraulic energy. When …
Determine the Appropriate Solution to Control Air Cylinder Speed
Because air is a compressible fluid, controlling the speed of actuators is a unique problem. A pressurized air cylinder that is not under load will extend …
The STAMPED Method for Selecting Tubing and Fittings for a Metal Tube Assembly
The acronym STAMPED, as used for hose assemblies, is equally as important to use when developing tube assemblies. The same factors apply; only the …
Adding Hydraulic Fluid to the Reservoir
Adding make-up fluid to the reservoir ranks among the most important maintenance tasks because of the consequences of doing it incorrectly. Be aware that a …
