The Twisted World Of Rotary Screws

Rotary-screw compressors are used when piston compressor power just won’t do. Jackhammers and construction machinery are prime examples of this.

Rotary-screws are first and foremost gas compressors. They use rotary-type positive displacement processes to produce compressed air. Pulsing or surging air is kept to a minimum by the sweeping motion of this compressor. Rotary screws are relatively small machines and due to their mechanism, emit little to no vibration. The power of these compressors varies with the size and function. The smallest ones are capable of operating at ten cubic feet per minute (CFM), while the industrial grade compressors can give off more than a two thousand CFM. Though that number is high enough to power large machines for construction, extremely high-powered machines (turbomachinery) such as jet engines need centrifugal compressors.

There are two types of rotary-screw machines. The first one is an oil-free rotary screw compressor, which is used for medical research and semiconductor manufacturing. There is absolutely no place for oil leakage in these processes. Oil-injected rotary-screw compressors are used almost everywhere else.

The drawback of this machine is leakage of oil and fluid into the rotary-screw chamber. The speed at which the screws rotate compensates for the leakage by making the compressor more effective, and the power output higher.

Air Compressor Disasters: A Safety Reminder

Air compressors are amazing inventions. They have countless applications that make life better for everyone. However, they are terribly powerful. When dealing with air compressors, people should be extremely cautious. These machines also need regular maintenance to ensure that they don’t break down. There have been disasters in the past due to air compressors breaking down. Here are two such incidents that occurred many decades ago, but are still remembered today. Such tragedies serve as lessons for everyone to respect these machines.

In 1929, there were two air compressor disasters that rocked the United States. The first one came in February, when an air compressor exploded in a quarry in Stone Mountain, Georgia. The explosion killed seven men who were about to leave for the day. It was speculated that the blast was caused by defects in the machine itself. Dozens more were injured.

Later that same year, an air compressor explosion killed three people in the city of St. Ansgar in Iowa. The explosion, which happened in a gas station, destroyed the buildings in the immediate vicinity and caused extensive damage to the surrounding structures, most notably the public library. It was also reported that windows of buildings several blocks away were shattered by the force of the explosion.

Although technology has evolved to improve safety at work sites, utmost caution and regular maintenance of these machines are still needed.

Air Compressor Tools and Accessories that will make the Job Easier

An air compressor can have expanded uses, but it needs accompanying accessories so it can reach its full potential as a machine. When you use an air compressor for your home or industrial projects, you will be more efficient in work, while exerting minimal effort.

These air compressor units usually come with accessories, but consumers may add additional ones, depending on the project they are undertaking. Here are main accessories and their uses that will best accompany your air compressor unit:

Hoses

A lot of air compressors come with hoses. A hose is attached to tools at one end, and to the air compressor on the other. The motor in the compressor forces the air, passing through the hose. It is important to choose a properly-fitting hose for your compressor. Otherwise, it won’t work properly. Hoses need frequent replacement because they could develop holes after many uses.

Hose reels

While retractable hoses are a trend these days, it is best to keep your primary accessory in shape with hose reels. These also come handy in hose storage.

Filters

You need to change your air compressor filters regularly. Not doing so will decrease your unit’s motor life.

Various tool attachments

Choose a nail gun for roof attachments, paint sprayer to cover the area easily with paint, drills to dig holes on walls and other surfaces, and sanders to make sanding, polishing, and grinding easier.
