When I first started writing about blowers, it was a revelation to me that fluids like air move only from areas of high pressure to low pressure. To someone without a background in physics, fluid dynamics can be confusing and counter intuitive. But if you think about blowers and how they work, it can be helpful in understanding fluids and how they move around.
Belt driven or direct drive? That is the blower construction question. What are the advantages of belt driven blowers over direct drive blowers, if any? Let’s quickly review the difference. Direct drive blowers are blowers in which the motor that controls the rotation of fan blades is connected directly to the rotor shaft or fan axle. This means that the fan blades will spin at the same speed as the motor’s rotation. A belt driven blower features a motor that is not directly connected to whatever equipment the fan’s blades or impellers may be mounted on. Instead, one or more belts are used to connect the motor to the moving parts of the fan.
Every production method has a most basic level of operation, the level that started the trend or made the process popular enough to want to create alterations for specific applications. When it comes to the die cutting industry, the most basic technique involves steel rule dies. Working like a stamp, but one with sharp edges that pierces all the way through a material, steel rule dies are able to quickly and efficiently create die cut shapes for a variety of applications used in many industries.
As a kid as well as a teenager, I loved to swim, and participated in a number of swimming related activities. During grade school I was on our neighborhood swim team, and once I got into middle school I discovered the joys and struggles of synchronized swimming. Although some may scoff at this sport as simple water dancing, the physical stamina required to practice synchronized swimming is intense. During our 4 to 5 minute routines, we are never allowed to touch the bottom of the pool, which means we are constantly working to keep our arms, legs or torsos out of the water while retaining a sense of effortlessness and grace. This is not an easy fete. Both of these experiences gave me a grave appreciation for swimming goggles, the elements of which are fascinating.
Hydraulic press manufacturers create a variety of pressing machines for a variety of industries. In a factory, a hydraulic press can be used to shape metal, compress pieces together, or compact a larger item into a smaller, denser shape. Other hydraulic presses are used to cut out metal pieces, or compress rocks into powder.
Joseph Bramah is an inventor from England who was born on April 13, 1748 in Yorkshire, England. He started his invention work when he designed a lock, and received a patent for it in 1784. He soon started a lock company called Bramah Locks, whose locks were well known for their resistance to tampering and lock picking. In fact, they had a famous “challenge lock” hanging outside of the store, which promised to offer 200 guinea (a British coin) to whoever could open the lock. The lock remained unopened for 67 years, and it took the locksmith who eventually opened the lock 51 hours to do so. The original lock remains in the Science Museum in London.
Did you know that suppliers for hypodermic needles use a very special process to create the small, but strong needles? Each needle must contain a narrow, hollow center inside the needle for collecting blood or administering medication. The process of creating these tiny, hollow metal pieces made from stainless steel is quite interesting, and most companies will use a similar process to create their own needles. If you have ever wondered how hypodermic needles are created, look no further.
A mezzanine is an intermediate floor inside of a building, usually open and not walled off. There are a few different types of mezzanines; including stick built, fiberglass, and rack-supported. In general, the two most common types of mezzanines are cold rolled and structural steel. Understanding the differences in the way the two types of mezzanines are manufactured is crucial to ensuring you choose the right product for the job.
