IDIS 403 Ch 10 Questions with Detailed Verified
Answers
When heat cannot be properly dissipated, ___ must be placed in the system to help
cool the hydraulic fluid by removing damaging heat from the system. Ans: heat
exchangers
A ___ filter is placed before components to protect them from contaminants in
hydraulic fluid. Ans: pressure line
Pressure Filter Ans: filter designed to operate in high pressures and is placed before
one or more hydraulic system components to protect them from contaminants in the
hydraulic fluid
___ is a coating of a sludge-like residue that results form the breakdown of hydraulic
fluid from the heat and pressure. Ans: varnish
___ pressure is the level of pressure on the return line of a device in a hydraulic
system. Ans: back
A ___ is an artificial surface, usually a plate or wall, for deflecting, retarding, or
regulating the flow of fluid. Ans: baffle
Baffle Ans: helps clean and cool hydraulic fluid, separate out entrained air and water
from hydraulic fluid, and send hydraulic fluid to the pump
Air-cooled heat exchangers work best when the ambient temperature is lower than
____ degrees F. Ans: 80
A ____ is used to allow air in and out of a reservoir as hydraulic fluid is pumped into
the system. Ans: breather/filler cap assembly
A ___ is a holding tank for hydraulic fluid that is not in use. Ans: reservoir
Water-cooled heat exchangers have a max operating pressure up to ___ psi. Ans: 200
