TESTS IN 1 TESTBANK|700+Qs&As|GRADED A+
The pressure in the atmosphere which is always available to aid in pump
delivery is rated at ?
A) 17.4 PSIA
B) 17.4 PSIG
C) 14.7 PSIA
D) 14.7 PSIG
C) 14.7 PSIA
A normally closed valve connected between the pressure line and the
reservoir, its purpose is to limit pressure in the system to a preset maximum
by diverting some or all of the pumps output to tank when the pressure
setting is reached.
A) Pressure reducing valve
B) Pressure relief valve
C) Sequence valve
D) Unloading valve
B) Pressure relief valve - also known as maximum pressure relief valve, should
be the first valve located after the pump.
,What is the function of a pressure control valve in a hydraulic circuit?
A) Regulate flow
B) Regulate flow direction
C) Limit pressure
D) All of the above
C) Limit pressure
Where do pressure reducing valves limit pressure?
A) In one part of the system
B) Throughout the system
C) At the pump
D) All of the above
A) In one part of the system
The pressure at which a check valve will start to open is called?
A) Popping pressure
B) Pressure rating
C) Cracking pressure
D) Seating pressure
C) Cracking pressure
,The difference between the initial pressure which opens a valve and the
pressure to keep it open fully and operational is called?
A) Pressure rating
B) Pressure override
C) Operating pressure
D) Pressure compensation
B) Pressure override
The pump in hydraulics is the heart of the system circuits. It can be
unidirectional or bi-directional, it can be fixed or variable displacement, and
even pressure compensated to unload excess fluid back to the tank.
Considering all of this, a pump is only designed to do one thing.
A) Create fluid pressure
B) Create fluid flow
C) Create fluid flow resistance
D) All of the above
B) Create fluid flow
Three factors affect flow rate: pressure, fluid temperature, and orifice size. If
any one of these factors is increased, the flow rate will not increase.
, A) True
B) False
B) False
This type of valve is used in accumulator charging circuits to limit maximum
pressure and to direct flow back to tank when the desired accumulator
pressure is reached.
A) Unloading relief valve
B) Directional control valve
C) Pressure reducing valve
D) Pressure relief valve
A) Unloading relief valve
These normally open pressure controls are used to maintain reduced pressures
in certain portions of the system.
