chapter 15
A cylinder or motor in a fluid power system that uses the fluid power to create mechanical motion, converting the fluid into actual work
Actuator
A conveyor that allows product to gather
accumulator
the process by which moisture is attached to the surface
adsorption
A basic logic function, providing system control with an instruction to do this and this
And
The loss of pressure through a component in a fluid power system.
Head Loss
A valve that controls the amount of flow of the fluid
flow control valve
A sensor that provides a signal that is proportional to what is being measured, allowing knowledge of the exact position of a cylinder
analog sensor
A component with numerous ports, or ways, to which vowels and stacks of vowels can be attached to form circuits and functions.
Manifold
the speed of air passing across a filter
face velocity
a device that accepts heat and transfers it to the surrounding environment
heat sink
A valve used as a logic element, which allows an output if either input is received.
Shuttle valve
The range of change of the input signal that does not show any change in the output, signal the range of valves within which no action is taken, also called control hand in motor controls, the range valves between the make, and brake points for a switch or Contact
Deadband
A condition that occurs when vapor bubbles form at the suction side of the circulation pump, are drawn in by the pump, and then collapse as the hydraulic fluid is pressurized through the pump, creating noise and potentially damaging internal components.
Cavitation
A pump that moves a fluid by trapping a certain amount in a sealed area and then forcing the trapped volume into a discharge pipe
positive-displacement pump
A component located between the two stages of a two stage pneumatic compressor, which removes heat from the compressed air, thus increasing the efficiency of compression
Intercooler
In AC signal placed on top of the DC control signal that causes the valve to constantly micro move, which helps to reduce friction between the school and the body of the valve
Dither
a statement that pressure and volume are inversely proportional in a gas at fixed temperature, expressed as PxV=k
Boyles Law
a short tube with a narrowing point of constriction that creates an increase in fluid velocity and decrease in fluid pressure
venturi
A ceiling agent that hardens to form a tight seal under conditions without the presence of oxygen
Anaerobic adhesive
A situation in which a system seesaws back-and-forth dramatically from fully open or on to fully close or off due to gain being set too high
