Hydraulic cylinders are commonly found in industrial machines. Consisting of an actuator, it uses hydrostatic energy to generate force. Hydraulic cylinders essentially use fluid to create a pull or push force. Because they contain fluid, however, they require the use of seals. There are hydraulic seals found in most hydraulic cylinders. What are hydraulic seals exactly?

Overview of Hydraulic Seals

Hydraulic seals are gasket-like rings that are designed to seal areas between the components in a hydraulic cylinder. Hydraulic cylinders contain many different components, some of which are exposed to the fluid. To prevent fluid from leaking around these components, hydraulic seals are used. Hydraulic seals are designed to fit the components in a hydraulic cylinder while creating a leak-proof seal around them.

Hydraulic seals are essentially o-rings. However, they feature a groove within the lip that allows them to fit the components with which they are used. The groove will slide over the component to create a leak-proof seal. Even when the hydraulic cylinder’s piston moves and its fluid pressurizes, the component won’t leak. The hydraulic seal will keep the fluid within the appropriate container so that it doesn’t leak around the component.

Hydraulic Seal Materials

You can find hydraulic seals available in several materials. Rubber is a common material used for hydraulic seals. Rubber hydraulic seals are elastic, resistant to cracking, and long-lasting. There are also polyurethane hydraulic seals. Polyurethane hydraulic seals feature many of the same qualities as those made of rubber, but they are typically stronger and better protected against wear. While not as common as rubber or polyurethane, some hydraulic seals are made of polytetrafluoroethylene (PTFE). PTFE is a synthetic material that’s flexible, strong and resistant to extreme temperatures.


Composite Centrifugal Pump Wear Rings

Pump Composite Wear Ring Key Features

Pump wear rings are simple components, but they have a profound impact on pump reliability, efficiency, and safety.

Most centrifugal pump designs include replaceable rotating wear rings on the impeller (impeller wear rings) and stationary wear rings inside the casing (case wear rings). The wear rings in a pump serve three key purposes:

Create the contact area between rotating and stationary parts inside the pump

Reduce internal recirculation from pump discharge to pump suction or between stages

Create hydraulic forces which stabilize the pump rotor

The wear ring running clearance impacts pump discharge pressure, flow, efficiency, power consumption, vibration, and cavitation. Using composite wear rings with reduced clearance has a positive impact on all these factors.

Composite Centrifugal Pump Wear Ring Advantages

Long-term, large-scale field studies have shown that composite materials can improve pump life by up to 100%, reduce vibrations, and reduce seal leaks. Field tests and pump test stands have shown that reduce clearance can improve pump efficiency anywhere from 2-5% for typical process pumps. Additional pump composite wear ring material benefits include:

Eliminating the metal-to-metal contact points essentially eliminates the risk of galling or seizure

The wear rings will not seize or gall during slow roll or alignment

The pump will have a better tolerance of run-dry events and other process upsets, with a chance of surviving extended off-design conditions

Lower vibration due to improved damping at the wear rings

Fewer seal leaks due to reduced pump vibration and reduced shaft deflection due to tighter wear ring clearance

Higher efficiency due to lower leakage losses across the wear rings

Production

The first thing to consider when choosing between dry and liquid flavoring is, of course, the efforts and resources required to produce them. ;

Dry beverage flavors are most commonly produced by dry spraying, in which a mix of the desired flavor, water, and a carrier are atomized into hot air. At that point, the mixture cools quickly, trapping the desired flavors into their final powdered form. ;

Liquid flavors are a little more straightforward: you mix your desired flavors with your preferred carrier (and this varies depending on whether you are looking to produce water-soluble flavors, alcohol extracts, fruit flavors, etc.) instead of going through the dry spraying process. ;

Ultimately, liquid flavors are a simpler process, as dry spraying involves more steps and equipment. ;


ELEMENTS OF A CANDLE: FRAGRANCE

The addition of fragrance to a candle formulation is a common practice in the United States. In fact, an estimated 75 to 80 percent of candles sold in the U.S. are scented. Candle fragrance manufacturers work closely with fragrance companies to develop candle fragrances that are not only pleasing but will burn safely and properly.

The aroma from a lighted scented candle is released through the evaporation of the fragrance from the hot wax pool and from the solid candle itself. Like unscented candles, properly-formulated scented candles will primarily produce water vapor and carbon dioxide when burned. The only difference is that a fragrance is also released with a scented candle.

Most scented candles contain a combination of natural and synthetic fragrances These fragrance materials may be derived from essential oils or from synthetic aroma chemicals. A well-made candle will contain only fragrance materials approved for candle use; the addition of fragrance to a candle formulation should be carefully monitored to ensure that the candle will burn cleanly and properly.

Candle manufacturers can select from more than 2,000 aroma chemicals and essential oils to develop scents that are both pleasing to consumers and compatible with candle use. These fragrance materials are safe, high-quality ingredients that are also found in many perfumes, bath soaps, lotions, and shampoos.

Various health and safety tests are conducted on the raw fragrance materials that are used in candles and other consumer products. Reputable candle manufacturers use only expertly-formulated fragrances specifically approved for candle use.

Description:

Terry Knitted Fabric is piled jersey fabric made with a special attachment in regular circular knitting machines similar to woven fabrics. The Terry Knitted fabric has loops on the fabric surface. Terry fabric can be classified on the basis of weave, such as 2-pick terry, 3-pick terry, 4-pick terry, 5-pick terry, and so on. In the case of 2-pick terry, it can be formed at one side of the fabric. However, the stability of the loops is very poor due to poor binding in the main body of the fabrics. These fabrics were prepared especially for the bathrobes and because of the instability of the loops, this fabric lost its market.

Usage:

Terry knitted fabric is softer, more flexible, and more comfortable than woven terry fabrics. Terry knitted Fabric feels soft, with good extension, elasticity, wrinkle resistance, and moisture absorption. It has also excellent heat retention. Owing to its softness and absorbency, it is widely used in beachwear, towels, bathrobes, etc.


What is Single Jersey Fabric, What Are Its Features, and Where Is It Used?

Single jersey fabric is produced with the RL plain knitting technique. RL plain knit fabrics have plain (R) loops on one side and only reverse (L) loops on the other.

In the patterning of RL knits, different images are obtained by working with auxiliary knitting elements such as hangers and skips. Colorful patterns can be obtained with the jacquard technique. Patterns such as lines in the transverse direction can be applied with colored threads. In addition, it is possible to obtain different patterns by arranging the needle and steel arrays

SUPREM FABRIC PROPERTIES

– Their front and back faces are different from each other.

– Fabrics that are produced in the form of tubes, but can also be cut and used in the form of open width.

– Wider widths can be obtained in single jersey fabrics compared to rib and interlock fabrics.

– It stretches at approximately the same rate both transversely and longitudinally.

– If they are too stretched, their shapes may be distorted.

– When used as a garment, it is worse to wrap the body than other weft-oriented knitted fabrics due to their less flexibility.

– Single jersey knit fabric knit has fewer patterning possibilities than other knits.

– Since the knitting report is formed on a single needle on a single plate, it is the knitting type with the least amount of yarn spent per unit area.

– When cut, curls occur from the sides towards the back of the fabric and from the top and bottom towards the front of the fabric.

– They have less tendency to wrinkle.

Suprem knitted fabrics are widely used in summer outerwear, sportswear, and medical clothing. It is also used in underwear, although it is less used.

There are varieties such as emery single jersey (plain dye), ringed single jersey, ringed lycra, single jersey, boucle single jersey, and silvery single jersey. It is also used meticulously in Aydoğan Knitted Pajamas.

Live turret, as the name implies, is specifically driven by the CNC control and the turret of various spindle and powered sub-spindle configurations on CNC lathes to perform various operations while the workpiece remains in orientation to the main spindle. These devices, whether BMT or VDI, are also called driven tools, as opposed to the static tools used during turning operations. Live tools are usually customized for the particular machine tool builder’s turret assembly.

Most often, live tooling is offered in standard straight and 90º configurations with a variety of tool output clamping systems, including collet chuck, arbor, Weldon, Capto, whistle notch, hydraulic, HSK, CAT, ABS, and a variety of custom or proprietary systems developed by the many suppliers to the industry.


Investing in a Better Design

Bearing construction and the resulting spindle concentricity drive the life of any tool. A better design that costs just 10–15% more can yield both longer-lasting cutters and a consistently superior finish.

Of course, the stability and rigidity of the machine tool base are also critical factors, especially on large or deep-pocket workpieces where the distance from the tool base to the cutter tip is greater. Bevel and spur gears that are hardened, ground and lapped in sets are best for smooth transition and minimal runout. Roller bearings are consistently superior to spindle bearings in live tooling applications, so look for a combination system to get the highest possible precision. Also look for an internal vs. external collet nut so the tool seats more deeply in the tool. This produces superior rigidity.

Likewise, high-pressure coolant may be desirable. Look for 2000 psi (13.79 MPa) in 90º and 1000 psi (6.9 MPa) minimum in straight tools.


In a typical setup, the tools are mounted on a disc turret. With a face-mount version, the tools are located on the front of the tool-plate face; on a radial-mount or stair turret, the tools are arrayed on the OD of the tool plate. A servo in the turret powers tool indexing and operation. Driven by the CNC, with a wide range of possible spindles, sub-spindles, and tool holders, the live tools perform off-center operations while the workpiece remains oriented to the main spindle. ;

From the start, live tooling was added to increase a lathe’s usefulness. What many users of lathes and live tooling don’t realize is just how useful live tooling has become. State-of-the-art live tooling is versatile enough that it is applied even when the turning function of the lathe itself isn’t.

Fewer Setups

Other industry experts agree that a live-tooling system offers significant advantages. Frank Cerrito, general manager of Koma Precision Inc., East Windsor, Conn., put it succinctly, “The main reason customers invest in live tooling is that it allows them to do an operation that would have otherwise required another setup, off of the lathe. So it saves time and prevents possible errors.” ;

Leigh Bickham, product manager for Sauter and EWS live-tool distributor ITI Tooling Co. Inc., Ramsey, N.J., noted: “If you’re working on the OD of a part and you then need to mill a flat or drill and tap a hole, you can’t do that on a traditional static lathe. You’d have to move the part from the lathe to a mill. So, the idea behind live tooling was, ‘Let’s eliminate operations and make a turret that’s capable of handling drilling, tapping and milling.’ That’s the biggest advantage—eliminating setups and entire operations.”

Whether you’re shipping or storing something, we want to make sure you get your packaging right. The terminology between the two words often gets mixed up. And lord knows there’s just way too many special jargon out there in the printing world.

So to make things easier to understand for the rest of us, I will provide a simple rule of thumb below:

What’s the difference?

While both boxes and cartons are made out of paper materials, cartons are usually thinner of the two. You’ll see it used in cereal boxes, milk cartons, pharmaceuticals, and more.

A box, on the other hand, uses thicker paper stock that is mostly meant for shipping. As it’s built for durability, you will most likely notice multiple layers of paper that include an inside and an outer layer with a ruffled shaped paper sandwiched in between. Probably very easy to imagine since most of us have opened up a UPS or Amazon package at some point.

What’s the best for your business?

Depending on the industry, your packaging material may vary. What’s used in the food industry will differ from the footwear industry of course. So if you’re looking for packaging that is:

  • Lightweight

  • Affordable

  • Safe

  • Customizable

  • Eco-friendly

  • Durable

  • Or Affordable

Every year around this time, an "ugly" shoe trend seems to burst onto the scene and become the "it" look of the season. It happened with tourist sandals in 2019 and Birkenstocks in 2018, and now it's happening again with water shoes.

If your parents ever made you wear these waterproof shoes at the beach when you were a kid, the term probably conjures up images of mesh, flexible footwear in bright neon colors. But water shoes have gotten a major makeover in recent years and now they're vying for the hearts of fashionistas everywhere, according to a new column in the New York Times.

Traditionally, consumers have relied on water shoes to protect their feet from rocks, provide traction and drain water during all sorts of outdoor activities. But similarly to Crocs, they've usually been a purely functional piece of footwear. "Since they were mainly used for water activities like kayaking, hiking and swimming, water shoes have not been regarded for their style," Sara Skirboll, RetailMeNot shopping and trends expert, told TODAY Style.

But in recent years, the shoe style has transformed in look and feel; nowadays, anything from sock-like shoes to sneakers and sandals can double as water shoes.

The style has even caught the attention of some well-known — and luxurious — brands. Balenciaga models walked down a wet runway wearing a type of hybrid water sock/shoe in March.

Popular footwear brand Teva also recently partnered with Opening Ceremony for a mesh "Hurricane Sock" shoe.

So why are people suddenly embracing this typically "ugly" shoe style? It might have something to do with our overall shift in fashion preferences during the coronavirus pandemic.

"Water shoes may be increasing in popularity as more people are finding new ways to stay healthy, fit and venture out while gyms are closed, which makes hiking, swimming and climbing perfect activities," Skirboll said.

With so many of us finding new ways to explore our own states and putting off scheduled summer vacations, shoes that are fit for outdoor activities have exploded in popularity, and designers have stepped in to dress up the typically utilitarian shoes.

"The desire for comfort and utility is more apparent than ever, but that doesn’t mean those who are fashion-forward want to disown their sense of style. Therefore, we’re seeing luxury brands fill this gap in the market by creating products like water shoes that are functional but still carry the clout of a high-fashion brand," Stitch Fix style expert Layne Cross told TODAY.

Society's sudden penchant for water shoes might also have something to do with the fact that "ugly" shoes, like Crocs, have been creeping into the mainstream for quite some time.

Looking at the light source itself through the diffusion we can clearly see how a combination of direct light and diffuse light creates a harder source (as in the Spun and Opal options). As the definition of the original light source becomes increasingly obfuscated by the diffusion material, the overall size of the source increases and the quality of light is softened substantially.

The Tough Spun has very interesting properties. As it is a fine pattern of thin threads, there are clear spots along the material where direct light can shine through. This means that it produces a combination of both hard and diffuse light. You can see this illustrated in the images of the geometric shapes from our test, as both the umbra and penumbra of the shadows are well-defined.

“Tough Spun doesn’t really change the shadow transfer value [from that of a hard-light source],” notes Williams. “The shadows are still sharp, with just a reduction in contrast. All three of the Tough Spun strengths have this same behavior. This effect is clearest in the heaviest of the three, Full Tough Spun, where the penumbra has a clean, hard line, and the umbra of the shadow, although diminished, is still clearly defined. The Light Opal, on the other hand — as minimal an effect as it might have — starts to produce a breakdown in the definition of the penumbra, denoting more softness to the light.

“It was very interesting to me that the Tough Spun lent a texture to the light, a lot like a cookie or a celo cookie,” Williams continues. “It’s subtle, but it does project a pattern onto the subject.” As with any projected pattern, the farther away the pattern-producing material is from the light source, the better-defined the pattern will be on the subject.

The amount of diffusion increases with 1⁄4 216, which, we can see, produces very similar effects in terms of shadow quality to 1⁄2 216 and 1⁄4 Grid Cloth. Full Grid Cloth and 216 also produce very similar effects to one another, although Full Grid Cloth offers more diffusion of the light, as can be seen in the more diffuse penumbra; the definition of the shape is almost completely gone.

To further understand how diffusion works, we need to take a look at the material itself and see our light source behind it. The quality of light is created by the size of the light source relative to the subject, but if our diffusion material isn’t wholly opaque and we can still see some of the original source behind that material, then the actual fixture — in addition to the “new” light source created by the diffusion — has an effect on the overall quality of light. This is how lighter diffusions, even at the same size and placed at the same distance to the subject, create light that is less soft than what results from heavier diffusions — because they effectively combine the scattered light of the new apparent light source with the direct light of the original source, which is farther away and smaller.

Before taking your blood pressure

  • Find a quiet place.

  • Check to be sure you have the correct size cuff. If you are not sure, or if you have questions, talk to your healthcare provider. (Avoid wrist and finger monitors to ensure an accurate blood pressure reading.)

  • Roll up the sleeve on your left arm or remove any tight-sleeved clothing, if needed. (It's best to take your blood pressure from your left arm if you are right-handed. However, you can use the other arm if you have been told to do so by your healthcare provider.)

  • Rest in a chair next to a table for 5 to 10 minutes. (Your left arm should rest comfortably at heart level.)

  • Sit up straight with your back against the chair, legs uncrossed and on the ground.

  • Rest your forearm on the table with the palm of your hand facing up.

  • You should not talk, read the newspaper, or watch television during this process.

Taking your blood pressure

If you buy a manual or digital blood pressure monitor (sphygmomanometer), follow the instruction booklet carefully.

Record your blood pressure

If you have been asked to record your blood pressure and bring your readings to the office, please write down the date, time of day, systolic and diastolic numbers, heart rate, and which arm you took the reading on. If you are taking part in a program that has remote monitoring, your blood pressure readings are automatically shared with your medical provider. If you are unsure, please ask your provider.

This blog post is part of a new feature on AWRF where our members provide valuable insight into the industry.

Mishandling of workplace materials is the single largest cause of accidents in the workplace. Fortunately, most of these accidents are avoidable. With wire rope slings playing an important role with cranes, derricks, and hoists, it’s important to understand how to make a proper selection.

A wire rope sling is made of wire rope. It is composed of single wires that have been twisted into strands. These strands are then twisted to form a wire rope.

Here are 4 important characteristics to keep in mind when selecting a wire rope sling

1. Strength

The strength of a wire rope sling is a function of size, grade, and construction. It needs to accommodate the applied maximum load. The more a sling is used, both the design and the sling’s strength are reduced. A sling loaded beyond it strength will fail. For older slings it’s important to inspect often.

2. Fatigue

Wire rope slings must be able to take repeated bending without wires failing due to fatigue, sometimes called bending without failure. The best way to preventing fatigue failure is to use blocking or padding to increase the radius of bend.

3. Abrasive Wear

The ability of wire rope to withstand abrasion. It’s determined by size, number of wires, and construction of the rope. Remember that smaller wires bend easier and offer greater flexibility, which also means they are more susceptible to abrasion.

4. Abuse

The misuse of a wire rope will cause the sling to be unsafe well before any other reason. Kinking or bird caging will reduce the strength of a wire rope. Bird caging is forcibly untwisting the wire rope strands and they become spread outward. Be sure to keep up proper use per the manufacturer specifications.

These are just four factors to consider when determining the best wire rope slings for your application. Keep in mind that weight, size, flexibility, and shape of the loads being handled will also affect the life of a wire rope sling.

In the ongoing debate of air conditioners vs air coolers, we list down few important pointers that will offer a clear idea of why you should opt for an air cooler.
But first things first, should you buy an air cooler?
A cooler can be used by everyone, especially people living around hot and dry weather. One can choose from a dessert cooler, a window cooler or even a personal cooler, depending on the requirements.

Read on to know more about why to choose an air cooler over an air conditioner.

Have you ever wondered about how an AC or an air cooler functions and how does it affect the quality of air in your home?

An air conditioner circulates the internal air of the room over and over again, whereas an air cooler pulls fresh air from outside and then cools it down. Also, air cooler doesn’t make the air overly dry like an air conditioner. Because of the way it operates, an air cooler offers better quality of air for your room. So much so, that the air circulated from an air cooler is preferable for people with asthma or dust allergy.

When it comes to value for money, an air cooler definitely scores high over an AC. Even though both end up cooling the room, an AC can cost anything ranging from ₹30,000 to ₹60,000, whereas a cooler will be available from ₹5000 to ₹15,000. Also, apart from the initial cost of purchasing, even the operating cost of an air cooler is less than an AC. You can approximately expect 80% less electricity bill from a cooler as compared to an AC, making it economical in the long run.

Going green is something that concerns all of us, and air coolers trumps the card here as well. Air conditioners use CFC (Chlorofluorocarbon) and HFC (hydro-chlorofluorocarbons) as their refrigerant, which is quite harmful to the environment. On the other hand, air coolers are eco-friendlier, since they use water as the refrigerant.

Air cooler requires no installation, which is a cumbersome task in the case of an air conditioner. Whether you have a window AC or a split AC, they require additional arrangements for installation. An air cooler, on the other hand, can be simply moved into your home as an appliance. Many of the air coolers also come with castors, making it more convenient to move them around from one room to another. As you can see that air coolers definitely have their own place in the world. Especially, since they come with such a host of features like silent operation, remote control, multiple speed settings and more. Moreover, nowadays coolers are digitally enhanced and aesthetically pleasing to fit right in.
