Understanding Sequence Diagrams in Fluid Power

A sequence diagram is a type of illustration that graphically represents the physical state of each component in a system sequencing charts can be used in electrical fluid or combined systems. They are used to aid the user in understanding the operation of the system and to help identify which components are actuated or energized at any given time during the system cycle. Many sequence diagrams are used as auxiliary documentation to assist with illustrating the information conveyed on schematics or circuit diagrams. While there is no official standard for drawing a sequence diagram, most are drawn with the time lapse on the horizontal axis and the action accomplished on the vertical axis. to build a sequence diagram each major component is assigned a horizontal line. the width of the line shows the time period during the cycle that each component is actuated or energized.

This video provides a visual understanding of the sequence diagram, and its associated electrical and mechanical schematic diagrams.

Switch and Valve Concepts Used in Fluid Power

Fluid valves
Pneumatic valves used in fluid power
(ASCO Numatics)
The direction in which a cylinder piston will move or a fluid motor will rotate can be controlled by the direction of flow into the device. A cylinder is said to reciprocate if it's piston travels back and forth being reversed automatically at each end of its stroke without human operator attention. In an air cylinder, automatic reciprocation can be stopped by an electrical action or by a shutoff valve in the airline. If stopped by electrical action it will continue to travel until it reaches one end or the other of its stroke. If stopped by shutting off the air, it can be made to stop anywhere in its stroke.

Fluid valves are typically described as being either in the open or closed position. As described, the open position allows the flow of fluid, while the closed position prevents flow. The normal position of the valve is defined as the position of the valve when its spool is unshifted and the power is off. This means that any mechanical actuators, such as springs, are in their non-actuated positions. Electrical actuators, such as solenoids, are powered off. 

The normal position can sometimes be referred to as the unshifted, de-energized, or unactivated position. Valves that do not have mechanical or electrical actuators do not have a normal position because they must be manually moved. When shifted they remain in that state until manually shifted to another position. The terms normally opened and normally closed are used to describe the condition of a valve when it is in the normal position.

Watch the video below for a better understanding of these concepts.

The Fundamentals of Fluid Power

Fundamentals of Fluid PowerThe purpose of fluid power is to transmit power from one location to another. In the mid-1600s Blaise Pascal, a French mathematician, made a very important contribution in the field of fluid motion. This contribution, known as Pascal's Law, relates the transfer of pressure through a fluid. Pascale determined that a contained, pressurized fluid will exert pressure equally in all directions. Pascal's Law states that pressure set up in a confined body of fluid acts equally in all directions and always at right angles to the containing surfaces.

Another important property of fluid mechanics was discovered in the late 1600s by Robert Boyle, an Irish physicist. Boyle's Law is an experimental gas law which describes how the pressure of a gas increases as the volume of gas decreases. A modern statement of Boyle's law is the absolute pressure of a confined body of gas varies inversely as its volume, provided it's temperature remains constant. In a physical system this means that as the volume decreases, the pressure increases. Similarly, as the volume increases, the pressure decreases. Boyle's Law can be expressed mathematically as the pressure at state 1 times the volume at state 1, is equal to the pressure at state 2 times the volume at state 2. This is true as long as both the temperature and mass, or amount of gas, remains constant.

In the late 1700s Jacques Charles, a French scientist and mathematician, discovered an important rule regarding gases under pressure. Charles's Law, also known as the Law of Volumes, is an experimental gas law which describes how gases tend to expand when heated. It states that if the pressure of a gas is constant, and it's temperature is raised, the volume will also be raised by the same ratio. Additionally, the inverse is true. If the pressure of a gas is constant, and the temperature is lowered, the volume will also lower. Charles's Law can be expressed mathematically as the ratio of the temperature at state 1 to the volume at state 1, is equal to the ratio of the temperature at state 2 to the volume at state 2. This law is true as long as the pressure and mass remain constant.

In the mid-1700s, Danielle Bernoulli discovered another very powerful rule in the field of fluid mechanics. Known as Bernoulli's Principle, this rule is related to the Theory of Conservation of Energy, which states that energy can neither be created nor destroyed. In this fluid system, pressure is potential energy and fluid flow is kinetic energy. Bernoulli's Principle states that an increase in the speed of an incompressible fluid occurs simultaneously with a decrease in pressure.

Toward the end of the video below, this is illustrated by the flow of water through a pipe. The volume of water flow through all three sections is the same when the waters flow is restricted. In Section B, the speed of the water increases to maintain the same amount of volumetric flow. This increase of speed simultaneously causes a decrease in pressure. When the flow of water reaches section C, the inverse occurs. The water flow decreases and the pressure increases. This rule can also apply to the types of energy present in the system. As the pressure decreases in Section B, the potential energy converts into kinetic energy. This increases the speed of water flow and decreases the pressure. When the water reaches section C, the kinetic energy is converted back to potential energy. This is illustrated by the decrease in speed of the water flow and it's simultaneous increase in pressure.
