Belts that Squeeze

Written by Thomas Yoon


Belts have many uses inrepparttar running of equipment. The most common belts are used to transmit power from a prime mover (usually a motor) to another rotating machine.

Have you heard of belts used for removing water from sludge?

Yes, there is a type of equipment used in wastewater treatment that uses belts to remove water from sludge. It's called a belt press.

This is how it works:

There are two continuously running belts made of woven polyester material inrepparttar 133434 belt press. There are many freely rotating rollers whererepparttar 133435 belts pass over.

The belts are typically about 2 feet wide, depending on repparttar 133436 design. There is an upper belt, and a lower belt. The arrangement ofrepparttar 133437 belts and their travel onrepparttar 133438 rollers is made in such a way that at some point alongrepparttar 133439 route, they will be placed tightly against one another. The pressing together of these belts squeezes outrepparttar 133440 water fromrepparttar 133441 sludge.

In order to work,repparttar 133442 lower belt is passed through a tank containing a mixture of sludge in water. Asrepparttar 133443 belt travels throughrepparttar 133444 sludge-laden water, some ofrepparttar 133445 sludge gets stuck onrepparttar 133446 upper surface ofrepparttar 133447 belt, and is carried along with it.

What to Look for Inside your Steam Boiler?

Written by Thomas Yoon


A steam boiler is a pressure vessel with a difference. The vessel is subjected to heat stress of expansion and contraction, internal and external corrosion, as well as intense heating on some of its surfaces.

If we are not careful,repparttar steam pressure can rise up very high, and it can become a potential bomb!

Because of this, steam boilers have to be built to certain regulatory codes, with regards to materials used in their construction, their design, and their installation.

Forrepparttar 133433 operator ofrepparttar 133434 steam boiler, it is essential thatrepparttar 133435 boiler be operated safely. Although many safety devices are fitted in allrepparttar 133436 boilers, they are not fail-proof. Humans are still needed to monitorrepparttar 133437 condition ofrepparttar 133438 boiler allrepparttar 133439 timerepparttar 133440 latter is operated, even if it is just to acknowledge an alarm buzzer or flashing light in a control room.

One ofrepparttar 133441 most important ingredients of a boiler isrepparttar 133442 water inside it. The use of untreated water will lead to scaling, corrosion or foaming. All of these have some detrimental effect onrepparttar 133443 boiler or steam systems.

So, always treatrepparttar 133444 water properly.

But however well you treatrepparttar 133445 water, you will never knowrepparttar 133446 condition insiderepparttar 133447 boiler until you actually see it.
