technology and livelihood education
industrial arts for grade seven quarter
4 week three part two our topic is power tools
the content standard for this lesson is
the Learners demonstrate an
understanding of the concepts in
Services the performance standard is the
Learners perform mensuration and
precautions here are the learning
competency and learning objectives for
review of the previous lesson name the
vocabulary power tools are electrically
or battery operated devices used to
perform various tasks such as cutting
drilling grinding or sanding they
increase efficiency and Precision in
tasks that would otherwise require
manual effort and are commonly used in
maintenance pneumatic tools are powered
by compressed air making them efficient
for heavy duty tasks in Industries like
construction automotive and
Manufacturing these tools include drills
impact wrenches Sanders and grinders
offering high torque and precision they
are durable lightweight and reduce
operator fatigue compared to manual or Electric
Tools hydraulic tools use pressurized
fluid to generate Force providing
powerful and precise performance common
in construction automotive and
Industrial applications they include
Jacks presses and Cutters these tools
offer high efficiency torque and
tools the power tools most modern
construction or manufacturing
applications will likely utilize one or
a combination of two power sources
hydraulic and pneumatic the distinction
between pneumatics and hydraulics is
based on the medium used for power
transmission pneumatics rely on
compressible Gases such as air or pure
gas at the same time Hydraulics use
incompressible liquids like mineral oil
ethylene glycol water synthetic fluids
or high temperature resistant fluids to
transmission comparison of hydraulic and
pneumatic power system pressurized air
air or gases are utilized in pneumatics
to provide fluid power while Hydraulics
rely on pressurized liquids like oil or
water when deciding between the two
factors such as cost Effectiveness the
nature of the materials to be moved
resource availability and space
constraints must all be considered for
instance heavy lifting equipment
occupies significant space and demands
substantial power unlike the smaller
scale requirements of robotic laboratory
or food processing equipment it is
important to note that each power type
has advantages and disadvantages
circumstances health and safety
considerations for pneumatic and
hydraulic tools pneumatic and hydraulic
tools like any other equipment have
advantages and disadvantages regarding
health and safety while they may reduce
specific hazards they also introduce new
ones hence it is crucial to carefully
choose the appropriate tools for each
task to identify and address the
associated risks this selection process
should be integral to the risk
assessment and control procedure
ensuring that the tools are
wellmaintained and operated by competent
individuals and following the
manufacturer's instructions is essential
additionally these tools share similar
hazards with other tools powered by
electricity the following are the common pneumatic
tools the air impact wrenches are very
efficient and can quickly remove nuts
and bolts they have a very high torque
and can easily remove even struck
bolts pneumatic drill these tools are
compact light and weight and can rotate
at a very high RPM the main advantage of
a Pneumatic drill over a regular drill
corded electric or battery operated
cordless is no overheating problem as a
result you can use it for continuous
drilling without giving it any break
brushed motor drills have the problem of
Sparks due to the carbon brushes in them
this can be a problem in chemical plants
in such places pneumatic drills or other
beneficial air hammer you might have
seen large hammers easily breaking
asphalt these are air hammers or pneumatic
pneumatic
jackhammers it is a topr rated pneumatic
tool for demolishing or breaking things
like big rocks and Roads air hammers are
potent tools that deliver more than
3,000 beatss per minute most hammers
come with variable throttles and the
operator must be highly skilled as even
the slightest trigger can cause much
properly tire inflator a popular air
tool even with general consumers rather
than industrial Workshop users is a
simple tire inflator there are several
tire inflators some use air pumps like
cars and bikes balls mattresses to
inflate tires a tire inflator with a
dedicated air compressor will be
necessary for heavy workloads and
semi-trucks paint sprayer a pneumatic
paint sprayer uses compressed air to
atomize paint creating a fine Mist for
smooth application it's commonly used
for large surface areas and detailed
work in Industries like Automotive
construction and art these sprayers
include airbrushes paint guns and
gravity feed system sys for efficient even
cating air tools make the job easy and
fast whether drilling holes tightening
loosening nuts or bolts demolishing
roads and buildings inflating tires
painting they are also known as
pneumatic tools as they use compressed
air as the energy source in contrast to
fuel electricity we saw the basics of
air tools how they work and different
hydraulic wrench a conventional
hydraulic torque wrench kit generally
comprises a hydraulic torque wrench a
particular hydraulic pump station for
hydraulic torque wrenches a double high
pressure hose and a high strength heavyduty
socket hydraulic jack a jack that uses a
plunger or a hydraulic cylinder as a
rigid jacking member simple lifting
equipment is generally only equipped
with a lifting mechanism to lift heavy
objects it is simple in structure light
move hydraulic puller is an ideal new
tool to replace traditional pullers it
has a compact structure flexible use
convenient carrying and operation fewer
restrictions on site Etc it is suitable
for various maintenance places if the
handle slightly swings back and forth
the hydraulic starting lever moves
forward the hook claws Retreat
correspond spondingly and the object can
out hydraulic nut Cutters are also
called nut Cutters in some Industries
for rusted nuts that cannot be
disassembled a nut cutter can be used to
cut the bolt without damage to the bolt
time hydraulic press is a mechanical
press that utilizes hydraulic cylinders
to generate compression force it uses
the hydraulic equivalent of a mechanical
press hydraulic crimpers are tools used
to connect the ends of two cables wires
or similar flexible materials such as
hydraulic hoses to match hose ends the
tool allows the user to create a crimp
connection through a hydraulic fluid
mechanism to transfer force from the
