How to Identify Common Pumping System Problems

Posted by on Oct 11, 2016 in Uncategorized | Comments Off on How to Identify Common Pumping System Problems

It makes sense to identify and correct problems associated with your pumping system in order to maintain peak efficiency. After all, this results in lower operating costs, less downtime and less fuel. Keeping an eye on your pumping systems, therefore, represents an investment in both value and performance. What are some of the common problems, and how can you address them? Poor Performance Have you noticed that there is a noticeable difference in the discharge flow? Could it be that the pump is taking much longer to do the same task than it used to? This could be due to several issues. The gasket could be leaking, there could be plugged suction, a suction hose lining could have collapsed or there could be a damaged impeller. Firstly, measure the discharge pressure and the vacuum suction when the pump is going. Compare these readings to those measured when the pump was initially installed. Higher than normal pressure readings at discharge mean that the suction vacuum has been decreased, and this indicates a block in the discharge line. It could also mean that a valve is faulty. Priming Issues If the pump is not re-priming as quickly as it used to, then there could be excessive face clearance. You should also check to see whether the seal has been compromised, whether all of the hardware is connected and whether the gaskets are sealed properly. Look to see if the recirculating port has been clogged. Noisy Pumps If you find that the pump is excessively noisy, then cavitation could be to blame. Check to see if the suction hose is plugged or has a lining that’s collapsed and also look to see if the strainers are clogged. It’s also possible that the bearings are on the way out. You should also check to see whether the problem is mechanical or hydraulic. Do this by running the pump for a short amount of time without any water. If the noise disappears, then it is a hydraulic problem. If the noise persists, it’s a mechanical problem. Frequent Clogging If you find the pump is clogging very frequently, then it may be that the strainer is not up to the job. It could be too small, or the clearance could be too wide. Check also to see if the strainer is unplugged. Overheating Pumps will overheat if the flow of liquid coming in or going out is restricted. Check and clear any...

Things You Should Consider Before Installing A Flue In Your Chimney System.

Posted by on Feb 2, 2016 in Uncategorized | Comments Off on Things You Should Consider Before Installing A Flue In Your Chimney System.

A flue is an integral part of your home’s chimney system that conveys exhaust gases from fireplaces, cookers, water heaters, boilers and generators safely to the outdoors. It works under negative pressure to draw the combustion products from the appliances. Before you install the flue system, these are some of the considerations you need to make with a registered installer: Flue pipe positioning Flue pipes are used to efficiently connect your appliances to the chimney. An adequate air supply is needed for the appliances to operate safely and effectively. You shouldn’t include excessive bends and horizontal runs because they can accommodate soot with a risk of blockage. This is why flue pipes should be kept as vertical as possible. Connecting flue pipes These pipes are well designed to connect your appliances to the flue system. You might choose from two available options; the glass like coating pipes and the single wall stainless steel pipes. You should ensure that the maximum horizontal length of the flue pipes from the outlet appliance to the chimney is 150mm. Also make sure that the flue pipe connection rises vertically for at least 600mm before any change of direction. Flue sizing It is important that the internal diameter of the flue matches with the appliance outlet. You should carefully choose a flue diameter that perfectly matches the combustion output from the appliance. For the safety of your appliances, they have to be fitting and equal in diameter. You should also strictly adhere to the appliance manufacturer’s chimney size recommendations. Gas flue block systems This area of flue manufacturing is for gas effect fires. You shouldn’t use them for burning wood or multi fuel appliance under any circumstances. These concrete blocks have an integral and narrow passage designed to bond into the adjacent blocks or brick work. So they will be easier to use. Flue and Chimney on-site inspection When the chimney and flue system is installed or renovated, it is a mandatory requirement that a checklist and mortice plate be completed after a thorough inspection. The checklist has the types of appliances and fuels that can be used with the installed flue and chimney systems. This ensures that the installation or renovation process has been carried out well and correctly. For maximum performance, safety and durability, it is important that the chosen flue and heating systems are wholly suitable for the intended purposes and that they conform to the relevant chimney and flue installation...

3 Tips When Using a Vacuum Sealer

Posted by on Dec 18, 2015 in Uncategorized | Comments Off on 3 Tips When Using a Vacuum Sealer

A vacuum sealer is essential in the manufacturing industry and is designed to increase the freshness of food items. Many different types of food items can be vacuum sealed, but it is important to note that vacuum sealing does not prevent food from spoiling if it is not properly stored. Most food items that are vacuum sealed must be stored in a freezer. If properly stored, vacuum sealed food items can last and stay fresh for a prolonged period of time. Vacuum sealing involves the process of extracting the air from the bag that the food has been placed into. Vacuum sealers are used in the manufacturing industry, but the same principles of use apply when using one at home. Before you vacuum seal food items to store in your freezer, it is important that you follow the most helpful tips. Freeze Liquids When air is being removed from the bag that the food has been placed in, this can sometimes result in liquids or food crumbs being sucked into the vacuum sealer equipment. This is not ideal and can actually harm the equipment. It is best to freeze food items that are in liquid form before they are vacuum sealed. If you are vacuum sealing food items that are in a powder form a filter must be used. Don’t Overfill  It is also important to consider how much food you want to place in a bag before you begin the process of vacuum sealing. It is important that the bag is not overfilled. It is best to leave at least a few inches of space at the top of the bag where no food is present. If you know that you will be resealing a bag numerous times, you need to leave a few inches of space for each new seal. Bags that should be used when vacuum sealing are specially designed and normally have additional space at the top of the bag that is specifically designed for the seal. Keep the Bag Smooth It is always good practice to keep the bag smooth when you are sealing the bag with food. If you have wrinkles in the bag, this will result in residual air being left behind. The effectiveness of the sealing is compromised if residual air exists. This means that all wrinkles must be removed and smoothness is preferred. If the first seal is not effective, it is possible to create another seal that is closer in position to the food. This allows you to avoid having to use a new bag. For more ideas, suggestions, or assistance, contact companies like W.A. Bag Closing...

Answers to Your Questions About Home Demolition

Posted by on Dec 2, 2015 in Uncategorized | Comments Off on Answers to Your Questions About Home Demolition

Demolishing a home or other structure on your property is probably not something you do every day, so chances are you have some questions or concerns with how the process works. Demolition doesn’t always mean actually blasting a structure, and you may be surprised at what’s involved with demolishing on your property. Note a few answers to commonly asked questions about demolition so you can discuss these with a demolition company when you’re ready for something to be removed from your property, no matter the size and type of the structure. 1. How much will demolition disturb the ground and soil? This is important to ask if you are planning on having a house demolished so you can build a new house. You may then need to call on a contractor to clear and compact the soil after the demolition is finished, as cranes and bulldozers might tear up the ground more than you realize. You might also have a preference for the demolition process, depending on your property. For example, if you have a small farm, you may want the process that will disturb the soil the least. A more controlled demolition that happens in stages inside the home and then outside might be less disturbing and better for the environment. 2. Are there dump fees for the demolition? This is important to note because a city dump usually charges an outside company when they want to toss their debris, and you may be liable for the fees from the dump if it’s not included in your contract. You need to understand this upfront so you know what to expect by way of added fees and so you know that the structure will be taken off your land, not simply demolished and then left behind. 3. Ask if they handle pools and other structures Don’t assume that a demolition company only handles homes, silos and the like, but ask if you have an in-ground or above ground pool that needs removing, as well as a shed, garage, retaining wall, stone fence or similar structures. A demolition company may very well handle all types of removal jobs on your property and may not necessarily only handle jobs that involve blasting. Smaller bulldozers and cranes can make quick work of tearing down a retaining wall or stone fence or removing your old pool and deck. Rather than assume you need to handle these jobs yourself, ask a demolition company if they can remove these items for...

Preventive Maintenance Tips For Conveyor Systems

Posted by on Oct 27, 2015 in Uncategorized | Comments Off on Preventive Maintenance Tips For Conveyor Systems

After being in use for extended periods of time, conveyor systems are bound to suffer wear and tear. Failure to attend to these wears and tears may at times leads to partial or complete breakdown of the conveyor system. While there is no full proof way to prevent conveyor systems from wearing out, there are several things that can be done to reduce the rate at which the machines wear. This article provides a few tips for undertaking preventive maintenance on conveyor systems. “Walk, Look, Listen” Preventive maintenance of conveyor systems has to involve a daily inspection or floor walk aimed at checking the health of the system. During inspection, it is important for one to be observant so as not to miss obvious signs of wear and tear such as conveyor belt shavings and oil drippings among others. Similarly, system operators should also take time to listen to the conveyor systems while operational. Unusual noises from these systems are often an indication that a system component is worn out or is failing. In a large number of cases these noises indicate that the sprocket or belt is misaligned or that the bearing drive is failing. Don’t Leave Out System Operators Under normal circumstances, preventive maintenance of conveyor systems is left exclusively for maintenance crews. However, system operators have a vital role to play in the prevention of wear and tear by virtue of the fact that they interact with the systems on a daily basis. As such, it is important for industrial enterprises to invest in conveyor operation training for system operators. This ensures that conveyor systems are operated as they should, which slows down the wear process. Conveyor operation training also involves training on safety compliances while operators are on duty. The risk of conveyor system accidents and incidents is therefore greatly reduced. Make Use Of In-Built Preventive Maintenance Features Modern technology has made it easier to carry out preventive maintenance on conveyor systems. A large number of new conveyor systems today come complete with software applications that allow the system to self-diagnose and detect problems early using remote diagnostics. The mentioned software applications exhibit a great degree of accuracy and can be the source of great relief for maintenance crews and conveyor system operators. Examples of other in-built features that aid with preventive maintenance include color indicators, clear inspection panes and lubrication levels that are easy to read and interpret. Prevention is definitely better than cure even when it comes to conveyor systems. For more information, contact companies like Britrac (Aus) Pty...

Reasons Why You Should Consider Purchasing a Stainless Steel Tank

Posted by on Oct 7, 2015 in Uncategorized | Comments Off on Reasons Why You Should Consider Purchasing a Stainless Steel Tank

It is true that there is a huge variety of options that you can choose from when looking to fulfill your storage needs, but not all tanks may cater to your needs specifically. Stainless steel storage tanks, for example, offer lots of advantages, which makes them the preferred choice for many business owners. One such advantage is their high durability level, a level no other tank can surpass. While storage tanks can be used for personal uses, they are generally built to be used in industrial settings for storing water, food, chemicals, and so on. If you are in need of a tank that you can use to store food, water or other things, then here are three of the main benefits that you could see from purchasing one made of stainless steel. Extended Durability Steel storage tanks are the most long-lasting types of tanks available on the market today. Whether you intend to store water, food, or other items, you can rest assured that your tank won’t break down after a couple uses. You are probably looking to acquire a storage tank that will safeguard your items for extended periods of time. Plastic or wooden storage tanks have various vulnerabilities, which might damage your stored items in the long run. For example, they can crack or rupture during extreme temperatures. Because stainless steel storage tanks are coated with chemical solutions that completely prevent oxidation and rusting, you will not have to fret about damaging the stored goods. Hygiene Stainless steel storage tanks are not only durable, but extremely hygienic as well. This is an important aspect that you want to consider if you are looking to store water or food in your tank, as you probably don’t want the food becoming contaminated by the interior walls of the tank. If you pick a wooden tank, it’s possible for small pieces of wood to fall off the walls and into the container, ultimately ruining the food. Recyclability Whenever you decide to buy a new storage tank, you must think ahead. What can you do with the tank once you no longer have any use for it? If you’re planning to sell one, you have to understand that not many people are eager to buy second-hand storage tanks, mainly because they subject themselves to more risks and hidden defects. This is why it is important that the tank you buy is recyclable. By buying a stainless steel storage tank, you can rest assured that you will get some money back from your investment once its purpose has concluded. Most scrap metal collectors will pay you well for your tank, and they don’t care that it’s...

Simple Tools for DIY Sheet Metal Cutting

Posted by on Sep 15, 2015 in Uncategorized | Comments Off on Simple Tools for DIY Sheet Metal Cutting

Sheet metal fabrication is an important process in the manufacture of equipment, automotive panels and building structures. The common products made through the operations include roofs, siding, drainage gutters, building facades, machinery components and heating and air conditioning systems. If you are interested in bulk sheet metal products, you should hire a metalworking fabricator or sheet metal workers for commercial services. These companies have the right tools, knowledge and manpower to handle custom, large-scale production. However, if you are interested in basic sheet metal manipulation on a small-scale for residential or small business use, you can handle the requirements with a few machines and rudimentary skill. Here are the main tools that you can purchase for cutting sheet metal materials. Hand Shears Hand shears are simple tools but they are indispensable in metal cutting, particularly for beginners. There are different designs in the market and the configuration will determine the type of work that they can perform. Tinner snips have the most basic construction, which resembles the common scissors. They are made from strong carbon steel, so they can cut most types of sheet metal materials. Aviation snips are also popular and valuable in a fabrication project. They are known as compound-action shears because they can be used in making more complex and intricate cuts than tinner snips. Power Shears Power shears are hand tools but they are enhanced using pneumatic or electric power. They are more advanced than basic hand shears, therefore they can handle different types of sheet metal. Moreover, you can choose large shears that can cut thick pieces of sheet metal during your DIY fabrication. On the other hand, you should note that these are designed to cut in straight lines and large radiuses. They are unsuitable for cutting intricate and decorative designs. If you are interested in tighter radii, consider purchasing the special throatless shears alternative. Angle Grinder The angle grinder is a favourable handheld power tool in sheet metal fabrication. The equipment is primarily used for cutting raw materials but you can also utilise it in other processes such as grinding and polishing. Basically, the angle grinder uses rotating discs for performing operations and you can modify the functionality depending on the type of disc installed. Common discs include cut-off or diamond blades, polishing pads, grinding stones and sanding discs. This means that you can perform diverse tasks without investing in new equipment. If your project requires specialised cutting, consider engaging sheet metal fabrication companies with tools such as laser cutters, milling machines, water jet equipment and plasma...

Three Brazing Techniques for Custom Metal Fabrication

Posted by on Aug 24, 2015 in Uncategorized | Comments Off on Three Brazing Techniques for Custom Metal Fabrication

The process of metal-joining is important in the fabrication of custom commodities, machinery parts and even tools. It is ideal when making complex designs, because small simpler components can be manufactured and put together. One of the common joining procedures in modern metalworking is brazing. The brazing process involves melting a filler metal and allowing it to flow into a joint in order to join two or more work pieces. It is different from soldering in that the filler metal has a lower melting point compared to the metal parts and higher heat levels are used in brazing. This metal-joining procedure may be a great choice for your project, because dissimilar metals can be put together and the finish of the joints is generally smooth. Here are the main brazing techniques to inquire about when making your custom metal fabrication order. Furnace Brazing As implied, furnace brazing uses a furnace to heat and melt the filler metal during the joining process. The furnace can be powered using electricity, oil or even gas depending on the application and the fabricator’s resources. This technique is favourable because it does not require skilled labour, so it is fairly cheap. The furnace is also suitable for mass production of custom metal commodities, since the space is large and it can handle multiple pieces or joints at once. Moreover, a conveyor belt can be installed to automate and accelerate the brazing process. The main drawback of this technique is the potential unreliability when making complex designs. Induction Brazing Induction brazing is a metal-joining technique which uses electromagnetic heating to melt the filler metal. The heat is generated using the standard alternating current, and it can generate high temperatures faster than other alternative methods. This is because the heat is created within the metal material as opposed to other techniques, which require an external heat source. Induction brazing is mainly used on ferrous metals, but ideally, it can be used on any metal which can conduct electricity. This is a good joining technique for all your metal fabrication projects, because it allows highly defined and selective brazing. Moreover, it can be used on intricate and basic custom designs. Hydrogen Brazing Hydrogen brazing is designed to join metals by exposing the work pieces to a high temperature environment filled with hydrogen. This technique is typically used in the fabrication of oxygen-free copper, steel and even ceramics. Hydrogen acts as a cleaning agent in the process, because it can reduce oxides. You should request for this joining process if you need bright...
