Tooling U 2 QUESTIONS &
ANSWERS(RATED A+)
What is flow capacity? - ANSWER A rating that indicates how much fluid a hydraulic
pump moves into the system in a given amount of time. Flow capacity, also known as
flow rate, is measured in gallons per minute (gpm) or liters per minute (lpm).
What is hydraulic system noise caused by? - ANSWER Pumps are among the biggest
creators of excess noise in a hydraulic system. A pump can create fluid noise, vibration
noise, and component noise.
What type of damage may occur when a hydraulic system operates above its
temperature range? - ANSWER Conductor expansion
Understand hydraulic horsepower (HHP). - ANSWER Increases as flow rate and
pressure requirements increase.
Understand what a filter condition indicator senses. - ANSWER Increased pressure
drops.
Understand what fluid system personnel should do when taking fluid samples from a
system. - ANSWER Operators should take fluid samples upstream of a return-line filter
or from sampling valves located throughout the system.
Fluid system companies either conduct their own tests or send samples to certified
laboratories. After testing, if the contamination level exceeds the system's target
cleanliness, technicians can provide additional filtering by using a bypass line with a
filter.
Understand which fluid system malfunction indicates catastrophic failure. - ANSWER
Catastrophic failure refers to the complete, sudden failure of a system or major
component. For example, catastrophic failure may result from a large contaminant in a
cylinder actuator blocking the system from producing useful work. Fluid systems use
filters to prevent contaminant-related failures.
Understand which devise combines the functions of an air filter and water separator in a
pneumatic system. - ANSWER coalescing filter
Understand which power variable describes the rate at which a hydraulic system
accomplishes work. - ANSWER Power
Understand what force causes rotation in a rotary component. - ANSWER Torque
Understand which type of pneumatic valve controls the rate of air flow. - ANSWER Flow
control valve
