chapter 1-30_part 1

Question 1

converts the pressure energy of the fluid into mechanical energy to perform tasks like moving or lifting loads.

Answer 1

hydraulic actuator

Question 2

provides rotational motion and torque, converting hydraulic energy back into mechanical energy for driving machinery.

Answer 2

rotational actuator(hydraulic motor)

Question 3

Components of a single-acting hydraulic cylinder:

Answer 3

piston
barrel (cylindrical housing)
a rod
ports

Question 4

has multiple stages that extend for longer strokes with a short retracted length

Answer 4

telescopic cylinder

Question 5

uses two pistons to generate more force in applications where a smaller diameter is required.

Answer 5

tandem cylinder

Question 6

Three main types of hydraulic motors:

Answer 6

Gear motors
Vane motors
Piston motors (Axial and Radial)

Question 7

convert the energy of fluid
back into the mechanical power.

Answer 7

actuator

Question 8

provide motion in a straight line.

Answer 8

Hydraulic linear actuators

Question 9

finite amount determined by
the construction of the unit.

Answer 9

total movement

Question 10

extend and retract a piston rod to
provide a push or pull force to drive the external load
along a straight-line path.

Answer 10

Hydraulic cylinders

Question 11

capable of limited angular
movements

Answer 11

Semi-rotary actuators

Question 12

Hydraulic cylinders are of the following
types:

Answer 12

*Single-acting cylinders.
*Double-acting cylinders.
*Telescopic cylinders.
*Tandem cylinders.

Question 13

is simplest in design and
is shown schematically

Answer 13

single acting cylinder

Question 14

the cylindrical housing of the piston

Answer 14

barrel

Question 15

produce force in one direction by
hydraulic pressure acting on the piston.

Answer 15

Single-acting cylinders

Question 16

cylinder extends to lift a weight against the
force of gravity by applying oil pressure at the blank
end.

Answer 16

Gravity-Return Single-Acting Cylinders

Question 17

pressure is sent through the pressure port
situated at the blank end of the cylinder

Answer 17

Spring-Return Single-Acting Cylinder

Question 18

The operation of a double-acting cylinder with a piston rod
on one side. To extend the cylinder, the pump flow is sent to the
blank-end port

Answer 18

Double-Acting Cylinder with a Piston Rod on One Side

Question 19

a cylinder with a rod extending from both ends

Answer 19

Double-Acting Cylinder with a Piston Rod on Both Sides

Question 20

used when a long stroke length and a
short retracted length are required.

Answer 20

telescopic cylinder

Question 21

used in applications where a
large amount of force is required from a
small-diameter cylinder.

Answer 21

Tandem Cylinder
