Industrial Rubber and Plastics

Industrial rubber and plastics are not the most attention-grabbing subjects on the surface. Our associations with rubber are generally limited to the interactions we have with rubber in our daily lives and because these examples are neither numerous nor particularly remarkable: it is rare that you will ever meet someone with a particular loud or well. an informational view of rubber, industrial rubber or its manufacture. But there is a very interesting side to not only rubber manufacture but beyond that the often invisible range of applications it is suitable for: in fact, industrial rubber is a very important material in facilitating various processes, the results of which we take for granted.

Among the most common uses for industrial rubber is the manufacture of seals. A seal is a relatively simple piece of equipment that serves to help ensure that the equipment is watertight or airtight as it should be. Achieving a tight, reliable seal is critical in a number of industries. In the food and beverage industry, for example, rubber seals are needed for dosing machines, filling machines and as part of the canning process. Strong rubber seals also play an important role in wastewater treatment both in hydraulic systems and to prevent leaks at pipe joints – something that is especially important when sewage is involved! In steel and heavy industry, among several seal applications are test tube plugs and large diameter seals for manufacturing.

In addition to the rather obvious use of rubber in the manufacture of industrial seals, it is also used for goods that are used directly by the end user. From walking stick ferrules, to rubber foot pedals and doorstops – rubber can be found in many forms throughout homes and is even more widely used in car construction: mats and pedals in cab hatches, seals in engines and all examples of foam rubber throughout the vehicle are just usage examples.

Plastics are just as common in industry and manufacturing. PVC in particular is treated with a plasticizer to increase flexibility and is then used for equipment such as strip curtains, hoses and conduit. PVC hose used in conjunction with rubber seals is a very important component in many forms of industrial and agricultural machinery: not to mention the important role it plays in the food and beverage industry and the various tasks this combination is used for the consumer market. The industrial uses of rubber and plastics are so broad and widespread that it is more difficult to name an industry that does not use them than to remember the industries that do. They may not be the most interesting things to discuss but they are the basis of the infinite processes and objects that make up our modern society.

Moving Liquid With an Industrial Vacuum

A common question we face is what rate a user might expect from an industrial vacuum system. This white paper addresses that problem for liquids – water, slurries, slurries – which rely on a degree of vacuum to pull the “solid column” through the hose. Solid products – sand, abrasive media, grains – do not rely on a vacuum, but rather on creating a high airflow that carries the solids with them. These products will be discussed in a separate whitepaper. Here we are talking about fluids.

A vacuum machine is typically defined by its suction (as expressed most commonly as inches of mercury, or “Hg) and its airflow (as expressed in the US as cubic feet per minute, or cfm). When a “solid column” of liquid is pulled through the hose, the airflow is not important….the system is under vacuum….while the “Hg becomes the dominant factor in determining flow rates for a given system.

The size of the hose used, the smoothness of its bore, the straightness of its runs, and the type of product all affect rate. Today’s whitepaper addresses what can be expected from a defined setup, using water.

The flow properties of water are well understood. Firefighters have made a science of its flow to help them determine the best layout of hose. To make things simple, we are going to look at a table that shows, for a given suction in “Hg, what rate water will flow through 100′ feet of a straight 4” diameter hose, or alternatively, how high that water can be lifted under vacuum. (Because of the laws of physics, a solid column of water cannot be lifted much more than about 30 feet….the atmospheric pressure which is “pushing” the water through the line is balanced by the weight of the water column, leaving no driving force upward. However, it is possible to make lifts up to ~100 feet through the introduction of air – meaning you no longer have a “solid column” of water. Triton can provide more information on how to accomplish that.)

5″ Hg – 324 gpm or 5 feet vertical lift

9″ Hg – 445 gpm or 10 feet vertical lift

15″ Hg – 587 gpm or 17 feet vertical lift

18″ Hg – 648 gpm or 20 feet vertical lift

26″ Hg – 790 gpm or 29.4 feet vertical lift

Let’s look at a vacuum that puts up 26″ Hg. The Triton T1500 and our other liquid ring vacuum systems put up 26″ Hg or more. At 26″, the machine can pull 790 gallons per minute of water through a straight 4″ hose, or alternatively it can lift a solid column of water 29.4 feet….or some combination therein.

Now let’s assume that you have to lift that solid column of water 10 feet. Looking at the table, you can see that it requires 9″ of vacuum to make that lift. Subtracting that 9″ from the 26″ that you have available leaves 17″ of vacuum to use for flow. We don’t show 17″ on the table, but you can estimate that its going to be in the range of 625 gpm. So, if you have 5000 gallons of water that you need to lift 10′ and flow through 100′ of a 4″ hose, it will flow at ~625 gallons per minute, and thus require ~8 minutes to do it.

This table assumes a 100′ hose. If it is a shorter hose, there will be less friction, and the rates will be higher. If it is a longer hose, there will be more friction, and the rates will be lower. Another 100′ section might reduce rates on the order of 30%.

Also, this table assumes a 4″ hose. A smaller diameter hose has more friction than a larger hose.

Finally, this table assumes water. The product you are trying to use may be heavier than water, which means it takes more force to lift the column, and there will be higher friction losses. To give an idea, here are the lifts that can be expected at 26″ Hg for products of various densities. Note that the value for water is the same as given in the previous table.

Water @ 8.3 lbs/gal can be lifted 29.4 feet

Slurry @ 9 lbs/gal can be lifted 27.4 feet

Sludge @ 11 lbs/gal can be lifted 22.4 feet

Sludge @ 14 lbs/gal can be lifted 15.6 feet

You can see that a heavier product can make a slight difference in terms of lift. Vertical lifting is the most challenging part of the job, and can be helped by introducing air into the inlet.

Understand Some Things About Machine Vision System

The manufacturing sector has been using the Vision System for inspection purposes at this time. Inspection of the production process is necessary to maintain high-quality standards. If you don’t know about machine vision systems, it’s a good idea to understand a few things about these machines. Let’s find out how the Vision System works.

Applications of Vision System Machines in Various Fields – As we know that many industries use Vision Systems today, such as the automotive engine industry, plastics, hardware, automotive, medical, pharmaceutical, electronics, printing, mining, metals, and many more. The major purpose of using the machine vision system is to achieve high-quality standards. Products with high quality provide many advantages for companies because they are expensive and of good quality.

Vision System Components – A Vision System is a powerful machine, as are its constituent components. These components include lenses, lighting, grip frames, thin cameras, smart cameras, smart sensors, and software systems. Processing software is tailor-made to follow your rules, and speed up your lines. All the advanced equipment aims to maintain high-quality standards.

Visual Inspection Machine Using Artificial Intelligence – This machine uses artificial intelligence to perform various functions such as taking measurements, color identification, pattern identification, pre-processing, packaged goods verification, surface scanning, etc.

Regarding product measurement, the machine vision system provides accurate results. It is very important to ensure that product measurements are accurate and precise. Accuracy is also required to identify colors. Color identification is useful for image processing with good results.

Manufactured products are produced in various types and patterns. Therefore, machine vision systems are designed to identify different shapes, features, logos and other patterns. Not only that, this intelligent machine also performs pre-processing checks and verification of packaged goods.

Pre-processing involves manipulating the captured image for better contrast and enhancement before processing, so that the operator is aware of the non-conforming parts that will be involved in the production process.

How about the verification of packaged goods? This verification aims to verify the various parts, assemblies, and packaged goods. The system scans many product features such as size, position, finish, different product shapes, etc. Through a machine vision system, you can also avoid products that are not feasible. Vision System will perform a surface scan to identify problems with the product due to contamination, cracks, scratches, etc. Scan inspection is essential if you want to achieve the best results by standards.
