Eaton Ch. 1 Flashcards
What is the force divided by the area equal
Pressure
Force = ?
Pressure X area
The input component of a hydraulic system is what
A pump
What are the input and output Components of a hydraulic system
A pump is the input And a actuator is the output
What is a power source in a hydraulic system
A prime mover
How do you find head of a system
Head is 0.4 psi per foot of fluid
What pushes the oil into the void of the pump
Atmospheric pressure
How is pressure to the inlet of the pump measured
By Hg/in
How is pressure created
By resistance
Pressures are additive when..
Resistance to flow is connected in series
The speed at which a piston travels or motor rotates depends on its size and the rate of oil flow also….
Consider the area of the cylinder
Area of a piston formula
Pie • r/ squared
If flow becomes turbulent then friction varies as the square of the….
Velocity
When is work done
Whenever a force or push is exerted through a distance
The formula above for …. does not take into consideration how fast the work is done
Work
What is the coefficient used in horsepower formulas
.000583
What are the first steps when building a hydraulic circuit
Picking a actuator
What does a directional control Valve take responsibility of
The direction of flow
Where is the relief valve placed in relation to the directional control valve
Before the inlet
