Understanding the Supply Chain
A supply chain is a system of people, organizations, and activities that work together to move goods or services from the supplier to the end customer. The …
Understanding Basic Fluid Power & Electrical Symbols and Their Analogies
Graphic symbols are used to indicate the components that make up a circuit. While they do not indicate the physical layout of the components on a machine, they …
Understanding the Application of Accumulators
Accumulator circuits store pressurized fluid. They are used for several purposes: Maintain system pressure. Absorb hydraulic shocks. Supplement pump flow. …
Calculating Peak Flow
The flow rate to power air cylinders is computed for a specific operating pressure on the cylinder rather than from available air pressure at the compressor, …
Determining the Cause of Excessive Vibration
Vibration is often caused by a rotating shaft member. For example: bent drive shafts, out of phase drive shafts, off-center pump couplings, loose components …
Identifying Pressure Relief Valve Symbols
Hydraulic components are illustrated using both simplified and detailed symbols. Simplified symbols show the function of the component, whereas detailed …
Understanding the Function & Applications of an FRL
FRLs (Filter, regulator, lubricator) are common in and specific to pneumatic systems. FRL, just as the acronym indicates, is a combination of 3 smaller …
Understanding the Theoretical Force of a Cylinder
Pascal’s Law is the foundational relationship between force, pressure, and area when working with a confined fluid. In order for a cylinder to move a load or …
Understanding Non-Compressible Fluids
Compressibility is the measure of the change in volume of a fluid due to increased pressure. Atmospheric air and the gases that make up the air are highly …
Verifying the Correct Component Operation
In order to determine whether or not a component is functioning correctly, the troubleshooter must understand the behavior characteristics of each component. …
