Each month Fluid Power Journal brings you an industry problem with a solution the following month.
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 …
Understand the Function of Hydraulic Components in Circuits: The Application of Pumps and Intensifiers
Pumps A pump is a device where there is a mechanism for increasing and then decreasing the size of a volume chamber by means of rotary and/or reciprocating …
The Effects of Pressure Compensated Components on Control Systems
Pressure Compensation (Hydrostat Function) with Proportional Directional Valves To maintain a relatively constant flow to an actuator regardless of variations …
Understand Flow Control Valves
The terms speed control and flow control are often used interchangeably to identify a valve with the primary function of limiting the velocity of an actuator. …
