ITEC 283 Final Exam Flashcards
True or False: Hydraulic motors are used to actuate the pump and generate flow
False
It converts hydrostatic energy into mechanical energy
Hydraulic motor
True or False: Hydraulic motor is a mechanical actuator that converts hydraulic pressure and flow into torque and angular displacement
True
True or False: Hydraulic motors are linear actuators
False
What is NOT a rotary actuator?
Cylinder
True or False: The sole purpose of a hydraulic motor is to generate flow and consequently pressure
False
Some applications were hydraulic motors could be used are
Drills, rolling mills, cement mixer
True or False: Cavitation is very common in motors but it can be prevented
True
True or False: Cushion valves are used to stop or minimize surge, shock and overload in hydraulic circuits
True
On a fluid power motor, the unit for speed is
RPM
True or False: Purpose of a pump is to create pressure in the system
False
True or False: Atmospheric pressure helps force the fluid into the pump
True
The two ports in a pump are
Pressure and vacuum
True or False: As the pump pressure increases, the volumetric output decreases
True
True or False: An external gear pump is one in which each gear is external to the other
True
All basic fluid power system must at least contain
Reservoir, filter, directional control valve
FRL stands for
Filter regulator lubricator
In hydraulics, a pump does two things
Creates flow, generates pressure
True or False: Flow control valves are classified in 3 groups - Directional control, pressure control and flow control
True
Is the art of generating, controlling, and applying smooth, effective power of pumped or compressed fluids (Such as air) when used to push, pull, rotate, regulate or drive the mechanisms of modern life
Pneumatics
