Bearings: Types And Uses In Industrial Applications

Posted by on 5:07 pm in Uncategorized | Comments Off on Bearings: Types And Uses In Industrial Applications

Bearings are used in all kinds of situations from vehicle use to heavy industrial equipment. A bearing is basically a device that helps enable movement while reducing excess friction and stress on other moving parts. These devices allow other moving items to roll smoothly and keep the level of friction to a minimum, thus prolonging the life of equipment and improving overall efficiency. Here is some information about how bearings work and the different types you generally find in an industrial application. How They Work  Bearings are essentially an item with a smooth metal surface designed to help something roll. The bearing carries the force and the weight of the load, which is why they have earned their name since they bear the brunt of the pressure from the load. Depending on the type of load, the bearing can handle different levels of tension. With a radial load like a pulley, the weight is placed on the bearing to help the pulley move more easily. With a thrust load, there is much more force applied onto the bearing. In some cases, bearings have to be able to handle both types of loads simultaneously. Think of it like a tire that must be able to roll straight in one direction as well as turn sharply and still function properly Bearing Types There are several different types of bearings used in machinery that can handle either radial or thrust load, or handle a combination of both. Industrial applications may need to use a variety of these types of bearings depending on the weight and specifics of the individual load. Here are some examples of commonly used bearings and how they differ: Traditional ball bearings: These kinds of bearings are commonly used in lighter load applications. They can be found in almost everything manufactured from hard drives to roller blades, and can withstand some weight but can suffer from becoming warped if they get too overloaded. Roller bearings: A roller bearing can handle much heavier loads. A good example of a roller bearing is a cylinder that can handle weight distributed evenly over a large surface area. A needle bearing can also be used, which is a smaller and thinner version designed to fit in smaller environments. Ball thrust: This type of bearing can handle heavier loads in a lower speed scenario. A good example of a ball thrust bearing in an everyday application are bar stools, which use these type of bearings to support the weight of someone sitting in the seat. Roller thrust: A roller thrust bearing can handle heavier loads than the ball thrust version. These types of bearings are usually found in vehicle transmissions to support large gears. These are just some examples of the most commonly used bearings that can be found in a factory setting as well as in the products people use every day. Without them, finding the needed support to help things operate smoothly would be much more...

Steps To Take When Something Really Heavy Smashes Your Industrial Plant’s Concrete Floor

Posted by on 12:23 pm in Uncategorized | Comments Off on Steps To Take When Something Really Heavy Smashes Your Industrial Plant’s Concrete Floor

When you suspend really heavy objects overhead and pass them along the assembly line suspended by chains, at some point something will eventually drop. When these exceptionally heavy objects drop from on high and come crashing into the concrete floor of your plant, it leaves an indelible mark, like an asteriod in the earth’s crust. Hopefully no one gets hurt when that event occurs, but then you will have a very large and very dangerous hole in your concrete floor. Here are some steps to take to remedy the situation quickly. Document the Accident in Pictures Before You Remove the Object  Unless the object actually fell on someone, leave it where it is. Document the accident in pictures as well as words. Your company’s insurance company will want to see this for themselves, but you cannot leave the object where it is nor can you shut down the plant until the insurance company can send someone to take a look. Then get a crew together to formulate a plan of action. Formulating a Plan and Carrying It Out The object will need to be picked up and moved to the warehouse so that the insurance company can examine it before it is taken apart. If it is about the size of an automobile transmission, a forklift may be enough to remove it, otherwise find a small crane to lift it out of the crater it created in the floor. Anything larger or heavier than that and you will need a crane to remove it (either an overhead crane or a compact crane with an extending boom). Then start making calls for a concrete contractor. Getting Estimates for the Concrete Repair and Hiring a Contractor Get a few estimates for the repair work your plant’s floor is definitely going to need. You may have to run the quotes by your insurance provider before you hire a contractor. Then hire the contractor who can remove the smashed chunks of concrete from  the floor and complete the job the fastest and with the least amount of time lost to the company. Part or all of the surrounding floor may need to be removed before an entire new slab can be poured in its place, and then the slab will have to dry and cure. This could take a few weeks, but your employees could probably walk on the new floor the next day if a contractor is willing to repair and replace the damaged concrete...

How To Make A Metal Chimney Cap To Keep Squirrels Out Of Your Chimney During The Winter

Posted by on 4:59 am in Uncategorized | Comments Off on How To Make A Metal Chimney Cap To Keep Squirrels Out Of Your Chimney During The Winter

A chimney cap can stop squirrels from entering your chimney and building a nest in it to keep warm over the winter. A nest can impede the flow of smoke and dangerous gases from exiting the stack when you start a fire in your fireplace, and can cause the smoke and gases to flow back into your house. The best way to stop squirrels from getting into your chimney is to put a cap on it. Here is how you can fabricate your own cap to put on your chimney.  You Will Need: Sheet Metal Metal Shears Metal Mesh Angle Iron Vice Pliers Hard Rubber Mallet Heavy Gloves Bolts J-Bolts Roll of Wire Drill Screws Plastic Anchors Step One: Measure Concrete Cap You need to measure width and length of the concrete cap that covers the bricks on the chimney (this cap prevents rain water and snow melt from damaging the brick and mortar on the chimney) to determine how long the strips of sheet metal have to be to form the base around the opening in the chimney. Also, measure how far the flue sticks out of the chimney to determine how long the posts have to be to fit the cap over the flue. The flue is typically made of ceramic tile and rises above the center of the concrete cap. Step Two: Create Base Cut strips of sheet metal about four to five inches wide to match the length of the dimensions of four sides of the concrete cap. You also need to cut four strips to serve as posts between the base and top of the cap – the length of the posts need to be higher than the flue. All the strips have to be bent in half lengthwise. The easiest way to bend the sheet metal is to put a length of angle iron that is longer than the strips of sheet metal you cut in a vice. Place the sheet metal strip next to the angle iron so one side is halfway above the flat surface of the angle iron that curves over the top of the vice when you put the straight edge side down into the vice. Tighten the vice down hard so nothing moves. Use pliers to start the bending the sheet metal. Then take a hard rubber mallet to pound down the sheet metal until it rests flat against the angle iron’s surface. Step Three: Create Top Cut a solid piece of sheet metal a couple of inches wider than the base. Drill two holes in the top where the posts will be placed. Step Four: Install Posts Clamp the posts to the corners of the base and drill a hole on each side through the base and the post. Insert a bolt through each and tighten with a nut. Drill holes on both sides of each post at the top. Insert a J-bolt into the holes and slide the long part of the bolt up through the holes you drilled in the top. Tighten both ends of the J-bolt with nuts. Step Five: Install Metal Cap Set the cap over the chimney opening and drill holes through the bottom of the base and into the concrete cap. Insert plastic anchors into the holes. Screw the base to...

Increasing The Efficiency Of Your Industrial Air Compressor

Posted by on 10:51 am in Uncategorized | Comments Off on Increasing The Efficiency Of Your Industrial Air Compressor

If you run an industrial business, chances are you utilize an air compressor. These incredible tools are useful for providing your facility’s tools with the focused blasts of air they need to operate properly. However, there’s a good chance your air compressor isn’t running as efficiently as it could. Utilize these simple techniques to greatly increase its efficiency.  Adjusting Direct Air Compressor Costs The direct cost of pressure is directly related to the pounds per square inch gauge (PSIG) produced by the air compressor. According to IEN.com, an increase of 10 PSIG causes a power use increase of about 5%. The example they used indicated that an air compressor delivering 110 PSIG needs 100 horsepower (HP), while one operating at 100 PSIG requires 95 HP. They estimate this will save 10 cents per kilowatt hour (kWh). Their estimated savings of this decrease? $7,025 per year. Keeping this in mind, try to find tools that require less power to utilize, yet which still provide you with adequate power. For example, let’s say you’ve been using an air hammer with 110 PSIG to drive in bolts during your industrial process. But you have been overpowering your air hammer by 10 PSIG to ensure that the bolts stay in place. Try decreasing the power by 5-10 PSIG to increase air efficiency, while allowing your tool to operate properly. Buy a Compressor That Provides Proper Air Flow Too many industrial facilities have overpowered air compressors. The thought here is that it’s better to have too much power than too little. While that is an understandable position, it’s simply wasteful to use too much power to operate a tool. Take a look at the air power needs of your tools and buy a compressor that provides the right amount of power. For example, QuincyCompressor.com discusses the fact that a half-inch wrench utilizes five cubic feet per minute (CFM) at 90 pounds per square inch (PSI). Your air compressor should provide at least 30 percent more CFM than is required for the tool. So, your half-wrench will require a minimum of 6.5 CFM. Calculate the air power needs of the rest of the tools in your shop utilizing this method and use the tool with the highest need as the top end power of your air compressor. This ensures your tools operate properly, without decreasing the efficiency of your compressor. Reclaiming Heat To Power Other Processes When in use, air compressors generate a large amount of heat. The amount varies, depending on the horsepower generated by the air compressor when in use. The general rate can be understood as 2,545 BTU of heat energy getting produced with each horsepower every hour. A typical 100-horsepower compressor, when other operations are taken into account (such as the running of the motor), produces 280,000 BTU of heat energy every hour. That’s a lot of excess heat energy, too much of which is usually just dumped by most industrial facilities. However, if you install heat transfer systems to your air compressor, you can take that heat energy and reuse it throughout your facility. Common ways to reuse this heat energy include: Space heating Operating a water heater Process heating Utilizing these methods can help increase the efficiency of not only your air compressor, but of the rest of your...

3 Types of Parking Barrier Systems to Consider for Your Office Parking Lot

Posted by on 6:00 am in Uncategorized | Comments Off on 3 Types of Parking Barrier Systems to Consider for Your Office Parking Lot

If you own an office building and want to ensure there are always enough parking spaces in your lot for your employees and clients, you might be considering a parking barrier system of some kind. A good barrier system keeps out those you don’t want to enter your building, but for best results, it’s important to know about the different kinds of systems you can get. Here are a few barrier systems to consider. Swing Arm A swing arm barrier system is one where a metal or wooden arm rises and lowers down to restrict access to your parking lot. Sometimes a parking lot attendant booth is set up near the swing arm, so that an attendant can check credentials and identification before allowing people in and out of the lot. If no such booth exists, an electronic system can be set up so that people can press a button and reach someone indoors who can remotely raise or lower the arm. An electronic stand can also be installed to issue tickets, if you choose. One disadvantage of such a system is that someone can accelerate the speed of their vehicle and break the arm that is place. If you do decide to use a swing arm system, be sure to only use a thick metal arm that cannot break apart. Bollards When you use a bollard as your parking barrier system, it can be very difficult for an unauthorized person to enter your parking lot. Bollards are strong, thick columns that span the length of any entrance to your lot. To lower the bollards and allow people in, you may opt for a remote intercom system. Bollards may offer more protection than a single arm system, as they are more difficult to drive through. Gates Rolling gates can be a suitable parking barrier system for your office building. It is more difficult to drive through than a single arm system, and anyone who wants to walk into your parking lot who doesn’t belong is unable to, or more likely to be seen, as they must take time climbing the gate. Rolling gates can be remotely opened through use of an intercom at the gate, or you can have a manned booth nearby. A gate can be as aesthetically pleasing as you choose and can be constructed from wrought iron, aluminum and other metals. For additional security, you may decide to install barbed wire across the top of your gate. Now that you know some of the types of parking barrier systems you can get for your office building, talk with a local contractor like Eastco; Mfg Corp about what kind of system will work best for your parking lot and your budget. With a good system in place, you can better control who comes in and out of your lot and your...

Using Propane Safely In Your Small Business

Posted by on 9:47 am in Uncategorized | Comments Off on Using Propane Safely In Your Small Business

If you are starting a small business that requires the use of propane to fuel commercial appliances and factory equipment, you need to provide your employees with a safe environment to avoid leaks, fires or explosions. Before you begin using propane, familiarize yourself with the following guidelines for propane safety in the workplace in order to avoid a catastrophic accident and damage to your valuable equipment. Transport and Refill Safety One of the first steps in administering your propane safety program is to hire a qualified transport operator to deliver the fuel safely and efficiently to your workplace. Licensed propane dealers will have the proper equipment to safely load the fuel into your storage tanks. When you need to adjust the settings of propane-fueled equipment or change propane cylinders, make sure that you and your employees wear protective gloves. Propane can cause burns that are similar to frostbite and, in high concentrations, can also cause asphyxiation. You can purchase safety gloves specifically designed for handling propane containers. The gloves come with a chain to hang them on cylinder overhead guards. Make sure to post a material safety data sheet about propane in a visible area in your workplace to remind employees of the risks associated with handling the fuel. Equipment Inspection Depending on the type of equipment you use, you may be required by law to schedule periodic inspections of propane equipment such as underground tanks. However, even if you are not mandated to conduct inspections, you should do so anyway to avoid operating defective equipment and putting your safety at risk. Some propane dealers will inspect your pumps, gas detectors and meters for you. For propane-powered equipment like forklifts, contact an authorized mechanic to conduct an inspection. If you have heating equipment that uses propane, make sure to have the devices inspected before the onset of cold weather. Safety Procedures When Something Goes Wrong If you have an airtight propane safety plan in place, you can still be vulnerable to human error and equipment failure. Typical scenarios that require immediate action include the following: Underground tank leaks Cylinder overfill Burning cylinders on propane-fueled forklifts Fire near an exposed tank Damaged underground tanks due to construction or landscaping work Even if you are able to contain an accident on your own without contacting the fire department, you should never attempt to use any of your propane-powered devices or turn on the gas without obtaining an inspection from your propane supplier or a licensed propane service...

New To Welding? What You Need To Know About Surface Preparation

Posted by on 1:14 pm in Uncategorized | Comments Off on New To Welding? What You Need To Know About Surface Preparation

If you’re new to welding, you’re sure to find that there are a lot of tips and tricks to learn. One of the most important things to remember when you’re looking to produce clean, strong welds is to start with a surface that’s as clean as possible. Even the smallest particles and contaminants can weaken the weld and interfere with the process. Here’s a look at some things you should know about metal surface preparation for new welders. Cleaning Up Coated Steel Coated steel isn’t going to take a solid weld, because you need bare metal exposed for the welding process to work properly. If you’re working with a coated metal product, use a grinding wheel to get rid of any coatings on the surface. Take your time with the grinder, though. Be as consistent as you can be in pressure and the time spent in each spot. You don’t want to make the surface of the metal uneven by grinding one spot more than others. Eliminating Rust If you’re dealing with coating-free metal, but there are some rust spots developing on the surface, those are going to have to go as well. Rust flakes under a weld can weaken the integrity of the weld, and may even eat through the metal underneath. If you’re just dealing with surface rust, steel wool may clear it away. For more extensive rust, you’ll want to break out the grinding wheel again. Don’t leave any rust behind, because it will continue spreading. Removing Prior Welds Don’t ever try to weld over the top of an existing weld. You’re not going to improve the condition of the weld by doing that, because the two won’t integrate together. It’s better to grind the old welding material away from the surface and start fresh. That way, you don’t have to worry about the old weld weakening the overall integrity of the structure. Finishing the Clean Up Once you’ve dealt with the obvious issues, use a grinding wheel to go over the entire surface of the metal lightly. You just want to remove any residue, contaminants or particles that may have settled into the surface. Oils, dust and similar particles can interfere with the welds otherwise. With the tips presented here, you can tackle your first welding jobs with the confidence that you know how to get the metal ready. The right preparation is vital to a solid weld. If you need more guidance or aren’t sure about a specific situation, talk with a local welder or metal fabricator like Checkpoint Welding &...

Aluminum Soda Cans: Why You Should Get Them Recycled

Posted by on 3:42 am in Uncategorized | Comments Off on Aluminum Soda Cans: Why You Should Get Them Recycled

Are you aware that each time you toss out an aluminum soda can that you are causing harm to the environment? It is also in your best interest to take your aluminum cans to a recycling center, as you can make a little money if you do. Find out below about the usefulness of getting aluminum soda cans recycled, as well as how much money you can make in the process. What Makes Recycling Aluminum Cans Useful? Getting aluminum cans recycled is useful for the conservation of natural resources. When new aluminum cans are produced, it requires mining to be done. The bad thing about mining raw metal is that it can cause the air to become polluted. Mining can also lead to the ground becoming less sturdy, which can lead to it caving in through the formation of sink holes. Aluminum soda cans are also environmentally dangerous because they can attribute to global warming. Droughts are harmful to both humans and animals because the heat destroys crops that are used for food. If the animals have fewer crops to eat, they can become unhealthy and die. Humans are then left with fewer plants, vegetables and meat sources, which also leads to higher food prices. When aluminum soda cans are recycled, you are contributing to keeping the environment clean. The great thing about scrap metal is that it can be recycled over and over again for a variety of different products. When the metal goes towards new products, it helps with the reduction of greenhouse gases in the environment. What Do Recycling Centers Pay for Aluminum Soda Cans on Average? You can expect to get paid based on weight. For example, 0.55 lbs. of aluminum soda cans are valued at an average of $0.28. The condition of the cans may also have an effect on how much the recycling center is willing to pay, as well as what aluminum is going for at the time the cans are recycled. You can check websites that show the price of metal in real-time if you want to make sure you are getting compensated in a fair amount. Don’t forget to clean out all of the aluminum cans before hauling them away, as some of the recycling centers may not accept them if they are not clean. Stop by a local scrap metal recycling center, such as Pure Metal Recycling, to see if they take aluminum. You can get paid for your cans and contribute to doing something useful for the...

Metal Fabrication: A Look At Cold Cracking In Steels And Prevention

Posted by on 7:38 am in Uncategorized | 0 comments

When welding metals during the fabrication process, it is important to pay particular attention to any hydrogen dissolving in the weld metal at the heat affected zones (HAZ). At temperatures below 600 degrees, steels are particularly vulnerable to cold cracking, also known as hydrogen-induced cracking. Cold cracking is a serious welding defect that needs to be addressed immediately, as it significantly compromises and alters the structural integrity of the steels. In-Depth Review of Cold Cracking Thicker steels tend to be more susceptible to cold cracking because there is a higher restraint that can serve as a heat sink. This leads to rapid cooling rates that are difficult for the crystalline structures within the metals to tolerate.  Rapid cooling results in the formation of martensite, which is a crystalline microstructure that is very brittle and lacks ductility. Hydrogen accumulation at the martensite builds pressure in the HAZ, which eventually causes the steels to crack.  Techniques That Prevent Cold Cracking Once cold cracks form, the structural integrity of the steels have been compromised permanently, and the steels should be scrapped and recycled, as they no longer have the tensile strength required. To prevent cold cracking, implement the following techniques: Pre-heat the base materials that are used before welding them, as this will reduce the speed of cooling and prevent the formation of martensite. When pre-heating the base, a pearlitic structure forms instead of martensite. In comparison to martensite, the pearlitic structure has better mechanical properties and is more ductile.  Rely on welding techniques that use only a minimal amount and concentration of hydrogen to prevent hydrogen from diffusing into the steels. In short, make sure that you select an appropriate welding process.  Back step the steels. To back step, you will have to weld in one direction for short lengths. Weld over the same area several times, so that the heat from subsequent welds can relieve stresses in the steels.  Keep the welded steels at a heated temperature after the job is done. This helps slow down the rate of cooling, which will allow any hydrogen that has diffused into the metal to diffuse out easily. Conclusion Cold cracking in steels is a serious issue that signifies that there are unaddressed problems in the welding procedures. In addition to maintaining temporal conditions during the welding process, maintaining constant storage conditions and using proper filler metals can help prevent cold cracking as well.
