Engineering Maintenance

A common question we face is what rates a user might expect from industrial vacuum systems. This whitepaper addresses that issue for liquids – water, slurries, sludges – that rely on the vacuum level to pull a “solid column” through the hose. Solid products – sand, abrasive media, grain – do not rely on vacuum, per se, but rather on creating a high airflow that carries the solid along with it. Those products will be addressed in a separate whitepaper. Here we are talking about liquids.

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 quite a bit of difference in terms of lift. The vertical lift is the most challenging part of the job, and can be helped by introducing air into the inlet.

The last 4 decades have seen the industrial woodworking machine redefined. As late because the 1970s, most high-grade wood cutting machines were floor-standing models that operated through a combination of automated mechanics and human manipulation. Concerning the router, these machines (e.g. plunge router) are still being used today. But they’re not the routers that most woodworkers prefer. Most woodworkers prefer Computer Numerically Controlled (CNC) routers, whose cutter heads are operated by a programmable computer.

The advantages of CNC Versions

When it comes to performance, a CNC version offers at least four benefits that many standard models do not:

* Large cutting table that accommodates multiple pieces at once
* Possibility to cut on five axes
* Excellent repeatability across large production runs
* Cutting capacity ideal for high-speed configurations

These benefits are responsible for the best-known characteristics of CNC machinery: remarkable cutting accuracy, impressive cutting speed, and also the elimination of bad cuts. Better yet, these benefits are achieved through a basic, four-part production process:

* Designing the piece that’ll be cut
* Incorporating the design into a solid CAD model
* Converting the model data in to the machine’s programming language
* Controlling machine operation because it produces the look

With regards to the machining process, a CNC router’s computer-controlled cutter heads offer woodworking companies four or five advantages that standard versions do not:

* Considerable decrease in human error
* Shorter training time to reach expert user status
* More workspace (one CNC model can replace multiple standard ones)
* Capability to have one person monitor several CNC router

Combined with performance benefits, these benefits create a CNC model the most popular industrial wood router. But it is not superior to a typical model in most categories, particularly cost.

The advantages of Standard Versions

Standard industrial grade models don’t have the production capacity of the computer-controlled counterparts. However they do offer the next benefits that CNC routers do not:

* Considerably lower purchase price
* Lower repair cost and maintenance cost
* Considerably smaller footprint
* Never produce a run of faulty pieces as a result of programming error

In case your production demand doesn’t require you to upgrade to a computer-controlled industrial wood router, utilizing a standard it’s possible to be the greatest option. Additionally eliminating the cost of purchasing a CNC model, additionally, it spares you the cost of repairing and maintaining it. Over a period of many years, the cost distinction between buying and operating a standard version, and buying and operating a CNC version could be hundreds of thousands of dollars.

Conclusion

In terms of technology, easy operation, and production capacity, industrial CNC models are superior to standard industrial models. However, if your standard version meets your requirements, purchasing a CNC model could be an ongoing waste of money. If you do need a CNC model, but its price exceeds your equipment budget, buying it as being used woodworking machinery can lead to 30% or more from the machine’s new sticker price.

Today, improve a packaging business of the employer need to focus on certain items so that the quality and also the exception in the existing packaging techniques. However, it’s not possible until someone will pay focus on the plastic packaging techniques Recently introduced, and adopt innovative molding machines for that manufacture of superior packaging. Due to excessive competition, patterns of several containers are now being introduced in the regular market. Schemes PET bottle designs are changing in the rate paid by competitors to be mixed up in market and to make products more attractive. The preform mold has become a prerequisite to carry out various operations of plastic containers. However, three-dimensional blow molding, hard- soft hard or soft technology soft-hard and co-extrusion blow molding is among the pioneering approaches for molding blow molding plastic-type to soften the specified shape across the curves.

Digital (or virtual) models are replacing physical prototypes within the engineering world’s task of designing new ideas. Creating a physical prototype can be costly in both time and money when it comes to sourcing materials, designing and fabricating parts, integrating individual component assemblies, etc. Once an actual physical model has been designed and constructed it needs to be tested, adjustments must be made, new parts designed and created to fix problems, and the process starts all over again, repeating before the physical prototype succeeds within the design goals it was initially meant for. Despite the most efficient engineering design team on the planet, time can be lost and wasted awaiting others to provide the materials and components necessary for your building from the physical prototype. Digitizing prototypes can and does save time and money.

A digital model (prototype) could be adjusted when problems are detected and can be solved without extensive delay. Using digital models greatly increases the productivity of engineers. By decreasing the time lapse between your discovery of a problem and implementing an answer inside a prototype design, a company’s idea can make it to market faster. The faster an idea could be prototyped and sent to market without compromising on quality, the greater the marketplace share the look will probably gain and keep. That’s the reason digitizing prototypes rather than creating physical prototypes has become increasingly popular.

Once engineers are carried out designing the digital model it may be sent anywhere in the world in the lightening speed of a modem rather than the potential snail-pace crawl an actual model is subjected and restricted to by a shipping company. Digital models allow simultaneous brainstorming by engineering teams anywhere and anytime which results in a synergistic approach to design and development that is not hamstrung by time, material and potentially complicated and expensive shipping restraints. Ideas and concerns could be identified, addressed, designed, implemented and tested in far less time, with far greater efficiency and cost effectiveness.

There are additional benefits when engineering with digital models. For instance, once a digital model is finished, you can use it by marketing teams to test and gain public interest before the product is manufactured. Marketing discussion groups could be convened anywhere across the globe to examine and explore the look prototype in its digital form to be able to profit the design engineers regarding perceived market demands and trends which the final product may require in order to be a very successful and profitable product. If changes are deemed necessary digital model could be redesigned and extensively tested far quicker and easier at a reduced cost than the usual physical prototype.

Besides increasing efficiency and decreasing cost, designs engineered digitally might have an effect on a product’s reputation. Designs which are second or third to the market are often considered “knock-offs” even when they’re of the same quality or price. Time it can take to simply obtain the materials necessary for an actual prototype can waste time required to get the product to promote first. Designing and engineering products using digital models brings ideas to market faster and helps companies get to the marketplace first rather than putting things off and resources vying for second place. Designing with digital models has become a lot more than the best option; it’s fast becoming the only real viable option.
