safety


PNEUMATIC TOOLS: are powered by compressed air. common types of these air-powered hand tools that are used in industry including buffers, nailing and stapling guns, grinders, drills, jack hammers, chipping hammer, chipping hammer, riveting guns, senders and wrenches.


air compressor work by forcing air into a container and pressurising it. then the air is a forced through an opining in the tank, where pressure builds up. think of it like an open balloon the compressed air can be used as energy as it's.

there are 4 different types of air compressor 

reciprocating air compressor-Reciprocating compressors (also known as piston compressors) are generally used to move gas at increased pressure. The main elements of the compressor are one or more cylinders, and pistons which move within them, rather like in an internal combustion engine.
centrifugal compressor-Centrifugal compressors increase the kinetic energy of the gas with a high-speed impeller and then convert this energy into increased pressure in a divergent outlet passage called the diffuser. Centrifugal compressors are particularly suited for compressing large volumes of gas to moderate pressures.

axial compressor-Axial compressors are widely used in industrial gas turbine and jet engines to provide a high pressure supply to the combustor.

rotary screw compressor-The rotary compressor is generally used where a large volume of high-pressure fluid is required. For large industrial applications, high power air tools like jackhammers and impact wrenches, pneumatic pumps, sandblasting operations. 


Here are some diagrams examples of air compressor  




safety for air compressor.

- Place your compressor in an ideal location that has clean, dry inlet air. Wet conditions can cause damage to your machine, as well as electrical issues.

- Do not use gas air compressors indoors.

- Perform a routine safety check before each use of your air compressor. Check hoses, ensure proper power supply, check oil level, etc.

- Always wear eye protection and hearing protection when operating your air compressor.

- Do not add or change the oil or fuel in your compressor while the unit is running or has recently been used. Your compressor could potentially catch fire while doing so.

- Make sure your unit is plugged into a properly grounded electrical outlet. If not, you could potentially damage the electrical panel of your compressor and also cause a fire.

- Use the proper extension cord for your unit if needed. A cord that is longer than necessary can cause loss of power or damage to the unit.

danger and hazard

Unfortunately, compressed air is not often recognized as a hazard by its users, which can lead to widespread misuse, serious injury or death. leading to potential injuries such as air embolism, ruptured ear drums or organs, and dislodged eye balls; • High noise – can result in temporary or permanent hearing loss.

PPE when using air tools in general:

-glasses 

-ear muffs

-mask

-safety boots

-protective clothing

Specific safety when using-

Impact driverBefore using your impact driver, take out the instruction and safety manual provided by the manufacturer. Make sure the workspace is safe and free of clutter. 

Air ratchet- Always wear safety glasses with side protectors when using an impact wrench. Never wear a tie, loose clothing, a watch, rings, or jewelry when using an air-impact wrench.

Dust off gun- Do not dust off your clothing. Do not blow at your or anyone else skin. Make sure there are no faults with the machinery and make sure to have full PPE on.

Air riveter- Always install a safety clip or retainer in order to prevent the set from being ejected during operation. Never point rivet guns toward anyone or "dead-end" them against yourself or anyone else. Noise is another issue associated with pneumatic tools.

ART

this is my painting 
my kaupapa is about nature and environtment. this painting is about flowers

the news is corona virus killing on people in the china countries

the death toll from me coronavirus has exceeded of the sereve acute 
respiratory syndrome outbreak in 2002 and 2003 in wuhan china. but the number 
of people who have recored nationwide has also risen in recent days, suggesting 
that the new virus fatality rate is relatively low.

the number of new cases has stabilized in recent days ,but world
health organization officials cautioned againts reading too much
into those figures saying that wuhan and hubei were in the midst of a
very intense outbreak

27 countries affected in corona virus and 421 death.
