Portable Industrial Vacuum Systems

Vacuum systems have always been used industrially to transport liquid products such as water, slurries or slurries, as well as dry products. This vacuum system may be truck based, or alternatively, on a portable platform such as a trailer or skid. A common question is how far the product can be transported, and how close the vacuum unit should be to the job. This paper answers the question for moving liquid products with a Liquid Ring pump based vacuum system.

For liquid products, it makes no difference how far you can run horizontally (up to 400-500 feet) as long as you use good seals and gaskets to prevent vacuum loss. Make sure you don’t experience any additional (unnecessary) kinking or lifting or lowering of the hose. It should be as straight as possible on a flat track. Use a slow 90 degree radius spin. The bend in the line reduces the loading rate significantly. Your vertical lift will be the hardest part of the process. No machine will lift a solid column of water more than ~30 feet. You can make very high lifts (over 100′) vertical if air is allowed to enter the column. Make sure your hose is not buried in the product for a long time….the system needs to swallow air.

You cannot burn a liquid ring vacuum system by burying the hose in the product; it will only make hot water in the water tank. When that water finally evaporates, you will lose your vacuum. When you add water back into the tank, your vacuum will return.

Hard tubing will greatly improve your flow by reducing friction losses. Maybe you can’t use it, but if possible, use it. (Hard tubing is usually Schedule 80 PVC, glued in a straight line, flanged cleaning at 90° slow radius, threaded end for flexible suction hose). Descending works best if you suck into the container. If it’s possible to do this, do it.

In general, larger diameter hoses provide greater vacuum efficiency and higher loading rates. Changing the diameter of the hose along the length of the suction hose can be a problem. Air velocity is directly dependent on the diameter of the hose, and variations in air velocity can cause blockages in solid products.

Hoses with a 4″ diameter can be handled by one person. Hoses with a diameter of 6″ require frequent disconnection or tag-teaming by two people. A better alternative is to use a wheelbarrow or a broom or sweeper to transfer the product to the hose. It is also possible to remove the intake and have two hoses working at the same time, under the right circumstances. A wand is available for the end of the hose to facilitate product retrieval, and often a makeshift grip is made of brooms and duct tape.

For solids, a 6″ hose can generally handle a maximum diameter particle size of 2″, a 4″ hose can handle 1″, and a 2″ hose can handle a maximum particle size”.

As indicated, hard tubing is best for reducing friction losses. If you don’t have tough piping, the next best thing is a smoothbore hose. Corrugated polyethylene hoses are lightweight and easier to handle, but long corrugated hoses can reduce speed dramatically. Most of the length of your hose should be hard tubing or fine bore rubber hose, with only the last part of the working end (<30′) being lightly corrugated hose.

Machine Vision and Inspection

This system is widely used by machine makers in the manufacturing industry as a method for checking the quality of products or components on a production line. They can be found all over the world and in a number of different environments.

A factory in England produces stainless steel washers of various sizes. The production line is very basic. Washers are punched out of large sheet metal where they are dropped onto a conveyor belt ready to be packed into bags. One day, a worker found a bag containing a washing machine without a hole in the middle!

A vision inspection system could be introduced to identify this kind of fault before the faulty washer is packaged. A camera, placed at a point along the conveyor would be triggered to take a picture of a washer as it passes underneath. The image from the camera is relayed to a computer system that is pre-programmed by an engineer to interpret the image of the washer and decide if it is acceptable or faulty. A washer identified as faulty could be removed further down the line allowing only acceptable ones to be packaged.

This is a vision system almost at its most basic. They can do an awful lot more! Taking the washer example further; the computer system could be programmed not only to detect the presence of a hole but also check the size of the hole, the size of the washer’s outer diameter, the quality of the punched hole’s edge, roundness, scratches, colour and a whole lot more besides. Moving on from simple washers, a camera system can be used to take measurements and check the quality, alignment and presence of extremely complex assemblies.

A more recent use of vision systems is for robot guidance. Many modern car production lines rely on cameras to guide the robot arms in manouvering components like windscreens carefully into place on their vehicles.

This is only a very simple overview of what is an often a complex and vital part of the manufacturing process. In further articles I hope to go into greater depth of what makes up a vision system and how it integrates into the production line.

Implementing Vision System in Manufacturing Industry

Vision System is the perfect technological advancement today. The main task of this machine is to track the related operations of the machine and its applications. The main purpose of this tool is to produce higher quality commercial products and makes the consumer experience better. Vision System collects data on each production unit every day and makes the production process more effective in every way.

The task of the vision system is to inspect production lines and other areas in all industrial units. This machine identifies parts to final assembly and packaging. Any mistake can cause a setback for the entire line, and the vision system saves you from crucial losses. The vision system improves efficiency many times over because the computer system can identify deviations and faulty products. The image of the damaged product is captured and then entered into the system. At the end of the line, they are removed.

Vision System helps predict damage to each unit. Industrial machine breakdowns often occur because, in industry, machines are used every day. They are also prone to breakdowns and errors. If the entire machine breaks down, it can cause a huge financial setback for the unit. However, by applying the Vision System, damage can be avoided before the production process starts. The machine will identify the signal and provide fault information.

All manufacturing and assembly industries that operate 24 hours need to apply the Vision System in each production unit. The manufacturing industry always runs production machines throughout the day and must ensure consistency of quality in the products that will be sold to the market. Vision System helps companies with large capacities continue to create high-quality products. How is this system able to maintain consistency of product quality? The Vision System collects many signals and identifies them also displays them in detail in 3D form. You will find detailed information about a product during the production process, such as the position of the bottle cap, labeling, sealing, etc.

The Vision System has a state-of-the-art camera. This camera captures the signal and defines it into a detailed 3D image on the computer. Displaying product information in 3D will help in understanding the product parts in detail. It doesn’t matter whether your product includes large or small components, all assembly will work as expected. So, If you want to ensure that the component assembly of a manufactured product meets the standards, you must perform a 3D inspection using System Vision.

Through the advanced inspection machines from Vision System, the manufacturing units can continue to check their production processes regularly and reduce errors. Manufacturing industry owners can easily find several Vision System manufacturers specializing in new systems today. Please visit several websites of Vision System manufacturers, and find a machine that fits your company’s needs.
