Noise Making Refrigerators: How To Deal With Sounds Made By Refrigerators

Posted by on Sep 25, 2015 in Uncategorized |

If you feel like you are  losing your mind because you hear strange sounds coming from you kitchen in the middle of the night, it’s not you.  The culprit could be your refrigerator. Sounds generated by refrigerators can be quite annoying, and until recently, manufacturers and scientists alike were also baffled by some of these sounds. Here are the most common sounds that emanate from a refrigerator and how you can deal with them. Cracking Sounds According to Dr Hasan Koruk, a mechanical engineer, these sounds are generated by the expansion and contraction of fridge components; as the temperatures of the components fluctuate, they cause stress on the components, and hence the expansion and contraction. The heater panel in particular is the main source of the cracks. Therefore, by changing the panel to a more appropriate design, you can minimize the rapid temperature fluctuations, and thus, the expansion and contraction processes. For instance, changing your heater panel to one that has stiffeners and ribs can dampen the sound that it generates. Squealing and Chirping Sounds These noises come from the inside of the refrigerator and are associated with motors of the cooling fans. You can carry out a simple test to determine where the problem lies by opening the door of your refrigerator and holding down the fan switch. If the sound persists while holding the switch, the problem might be a defective fan motor. Another test is to take the evaporator cover off – the cover is usually located at the bottom or the back of the freezer. You should have a clear view of the fan once the cover is off, and you can easily determine what the source of the noise is. If the fan is defective, the best remedy is to have a technician change the fan for you. Buzzing and Clicking Sounds These sounds originate from the outside of the refrigerator, where most moving parts are located. The condenser fan is the major cause of these sounds. It accumulates lint and debris that make the sounds, and hence it should be your main concern. A technician can locate the condenser fan and clean it with specialized equipment. But at times, there could be nothing wrong with the components of your refrigerator. The sounds may be due to ice collecting around the shroud of your evaporating fan. When the blades are rotating, they strike the ice and generate noise. Check for ice around the fan and take them out. Remember that the evaporator cover is either at the back or at the bottom of your...

Using Solar Bore Pumps to Your Advantage

Posted by on Aug 27, 2015 in Uncategorized |

Solar bore pumps are extremely beneficial in Australia, because the climate revolves around hot-sunny weather, which is precisely what solar panels need to operate. As a homeowner, having a dependable system that requires very little maintenance and essentially runs itself on your behalf means that you will have the peace of mind of not worrying about the cost or performance of your equipment. Here are ways you can take advantage of a bore pump system and more details on how they work. Benefits solar bore pumps offer. Installation is very simple, with the solar powered system needing only a motor, bore pump, and photovoltaic array. The array is mounted in a fixed position to increase pumping volume at a faster rate than if the array were not mounted. The bore pumps are often the most expensive aspect of your system, however, because they come in a range of sizes and powers, homeowners have the ability to find a pump that fits their specific needs. These systems are designed to last you at least two decades of reliable pumping. When beginning your search for a solar bore pump system, you’ll want to consult an experienced professional that is knowledgeable with the power, size, durability, and pumping volumes of numerous pump models. They should be able to help you, whether you’re a farmer, business, or simply a regular homeowner interested in having an eco-friendly system that saves you money. How they operate. Solar bore pumps are actually very straight-forward in their operation, with the solar panel array drawing its power from the sun, which in turn powers the motor, and then the motor powers the bore pump. Each pump is built near a stream or underground water source that is constant. As the pump is powered, the water is drawn from your local water source and pumped into a storage tank on your property. Because this method does not require any energy from utility companies and is entirely self-sufficient, you will not need to worry about large monthly bills should your water consumption fluctuate. This is a great benefit to farmers and businesses who consume a great deal of water each month. How you can save additional money. The government rewards home and business owners for energy-efficient systems that help save money on both the initial cost to setup the systems and also in monthly, quarterly or annually savings. These rewards are referred to as renewable energy certificates. When you purchase your systems, ask your provider about the renewable energy certificate program to enroll and get discounts upon...

Precautions to Take When Welding Aluminum

Posted by on Aug 7, 2015 in Uncategorized |

You may be wondering whether you can weld aluminum in the same way as you weld steel. This question is particularly common among new welders who taught themselves welding so they may not have a very good understanding of the different metals they come across during their fabrication activities. This article discusses some precautions that you should take if you are going to weld aluminum: Clean the Material and Weld Area Aluminum is highly reactive so you need to take extra caution to ensure that there is nothing in the environment to react with the metal as you fabricate a product out of it. For instance, you need to use a degreaser to clean the aluminum thoroughly so that it is free of surface contaminants. If you are unable to weld immediately then cover the surface (with heavy brown paper, for example) so that it is not contaminated. Tag All Welded Aluminum Another unique thing about aluminum is that its surface appearance never changes when it heats up. Consequently, you may be at a higher risk of injuries due to burns if you do not label the materials that you have just welded. You can tag the freshly welded aluminum as “HOT” so that you do not touch it accidentally (thinking that it has not been heated). Wear Protective Wear All the Time The surface of aluminum is very reflective so light easily bounces off its surface. This puts your eyesight and other exposed body parts at high risk of sustaining injuries due to that intense reflected light. Always wear welding goggles at all times so that this reflected light does not damage your eyesight. Thick overalls can also protect your skin from damage by this light. Heavy gloves will protect your hands from the intense heat in the aluminum since aluminum is several times more conductive than steel. Adjust How You Hold the Weld Torch Cleaner welds result if you move the torch away from you as you weld rather than towards you. This technique is good because you will be welding into the shielding gas that surrounds the torch flame. Welding towards you makes the torch miss the benefits of the shield gas and that produces weld seams that have visible heat zones in large areas around them. Use the tips above to improve your skills in welding aluminum so that your work is flawless and you remain safe during the metal fabrication process. Contact a company such as A.J.C. Electrical Service Pty Ltd to learn...

Why Use Precast Concrete?

Posted by on Jul 20, 2015 in Uncategorized |

Precast concrete is a construction product that is cast in a reusable form, which is cured in a controlled environment and transported to the construction site where it is to be used. Precast concrete can be used in construction of almost anything. Why should you choose precast concrete for your construction needs? Here are some benefits that is offers. Fast construction Precast factories have full time specialists in production of precast concrete, finishing, curing and handling. This ensures fast construction since the precast iron is cast and transported to the construction site as required. On-site casting might slow down work and the required specialists may not be available to undertake the processes. Versatility Factory production of precast concrete allows a wide choice of color range, surface finishing and customized shapes. Precast concrete is easily molded, enabling designers to include classical details such as keystones or match the finish of materials such as weathered stones. Textured and patterned precast concrete surfaces can provide pleasing appearances to buildings and structures. Durability Concrete is commonly used where structural stability of a building is to be maintained for longer periods. Factory produced precast concrete is manufactured by experienced workers using specifically designed concrete mixes that offer tighter tolerance and durability. With effective design, precast concrete structures can last for a very long time without constant renovations or maintenance. Safety Concrete does not burn. This makes precast concrete a good choice for commercial and apartment building. In case of a fire, concrete does not allow its spread to other parts of the building or from one building to another. Concrete is sufficiently strong to resist impacts, blasts and natural catastrophes such as floods and earthquakes. Cost effectiveness Concrete is an inexpensive and locally available material that can be easily cured in the factory to produce precast concrete. Repair and maintenance costs of buildings and structures made out of precast concrete are relatively low. Precast concrete is suitable for contractors who want affordable and high quality material for construction. Environmental sustainability With increased awareness on the need to use environmentally sustainable construction material, the use of precast concrete is the best bet for construction. Made of natural raw materials such as sand, cement, gravels and stones which are available almost everywhere, precast concrete minimizes negative impact to the environment compared to other construction materials. There are no toxic substances used in the production of precast concrete and it can be recycled without environmental pollution concerns. Structures and buildings made of precast concrete are more economical, versatile, sustainable and safe compared to other conventional construction systems. Learn more about the advantages by contacting companies like Cope...

Skip Bin Hire: Different Classes of Accepted Waste

Posted by on Jun 26, 2015 in Uncategorized |

Skip bins are effective tools for residential and commercial waste management. The pertinent hire companies provide a wide range of services including waste collection and disposal, and even commercial cleaning. In addition, most skip bin businesses recycle useful materials, and this contributes to environmental improvement.  If you are thinking about hiring a skip bin, it is important for you to know how to use the container efficiently. Poor usage is irresponsible, and it may result in financial penalties from the waste management company. One of the important aspects to consider before using the bin is the type of waste that you should dispose of. There are restrictions and regulations applied by most companies to protect their bins and prevent poor disposal of hazardous materials. Here are the main classes of accepted skip bin waste. General Household Waste You can dispose of general household rubbish into your skip bin. This type of waste includes furniture, plastic toys, scrap metal, waste timber, home appliances and paper. You can also put in bulky items such as mattresses, but they will take up a lot of space in the container. On the other hand, you should never throw in any putrescibles. even in small quantities. These types of material include food scraps and disposable diapers. Put these into the local council bin for proper and safe disposal. Construction Waste Construction waste refers to the materials produced during improvement projects such as renovations, remodels and demolition. This category of waste encompasses tiles, bricks, timber products, concrete and carpeting materials. You can also dispose of old fibreboards and particleboard as long as the material has been assessed to ensure that it does not contain asbestos. If you have such material in your home, you should get a document confirming the absence of asbestos in your home from a NATA-accredited laboratory. Asbestos-containing materials will require specialized disposal, so consult the waste management company for custom assistance. Yard Clean-Up Waste If you are carrying out a landscaping project, you will collect diverse waste materials from your yard. You can dispose of these items, including pavers, green waste, rocks, tiles and metallic objects, into your bin. If you are performing excavation, you will need a separate skip bin for soil and general dirt. Some waste disposal companies will also charge different rates for rubber-backed artificial turf. If you are uncertain about the acceptability of unique waste materials, it is advisable to clarify with the hire company before use. For more information, contact a local skip hire...

Advantages of Machines in Pallet Stretch Wrapping

Posted by on May 29, 2015 in Uncategorized |

Stretch wrap is primarily used in unitising loaded pallets before transportation, though the same application is extended to other types of containers. The stretch film is an ideal wrapping choice for shipping applications because the material’s elasticity improves stability of the loads. Moreover, it provides significant protection against dust, moisture, UV rays and even potential tampering. The stretch wrap can be applied by hand or you can purchase a machine wrapper for your operations. Here are the main advantages linked to choosing stretch wrapping machines. Consistent Application Pallet wrapping machines are mechanical and automated, so they facilitate uniform application of the stretch wrap. When hand stretch film is utilised by the loading employees, the results are inconsistent. Each wrapped load will vary widely since there is no mechanisation and each operator will use the stretch film differently. Additionally, a pallet wrapping machine is precise during operation so the finished package will be professional and visually pleasing. The clean look will project a good commercial image which is favourable for your business. Safety There are safety hazards linked to hand wrapping loaded pallets. An employee may develop back injuries by spending a long period of time hunched over the cargo. The pallet piles can also topple over if they are not manipulated with precision as they are wrapped. Furthermore, the hand wrapping operators are required to constantly carry the roll of film and apply enough tension so as to hold the packaged load together. This is strenuous to the arm muscles and the hands may form blisters. These problems can be eliminated by purchasing a stretch wrapping machine. Both semi-automatic and automatic wrappers are designed to minimise the physical strain on operators. They also support the loads during the process so the risk of sudden mechanical injury by falling containers is mitigated. Load Integrity The stretch wrapping film is primarily designed to protect the loaded pallets during transit. However, if the proper process of application is not followed, the load integrity will be lost and the cargo damage will be extensive. The film is essentially a highly stretchable plastic layer which is extended during the wrapping procedure. When the material recovers elasticity, it shrinks significantly and keeps the pallets together. Hand wrapping is limited because the operators will apply tension on the film depending on their physical strength, training and motivation. Low wrapping tension will compromise the integrity of the unitised load. A stretch wrapping machine is preset so it will always apply the right amount of pressure for a secure package.

5 Tips for Staying Safe When Using a Platform Lift

Posted by on May 4, 2015 in Uncategorized | 0 comments

Platform lifts are great for helping a person to reach a high place, for example, when trimming a tree or when carrying out DIY work on an elevated part of a property. Many people will hire out a platform lift for this type of work, but may have never used one before. This article may help, as it looks at some tips for remaining safe while using a platform lift. Inspect the Equipment It can be tempting to just park the lift and climb on board to get stuck into the work you into to do. But don’t do this. Instead, give the lift a once over visual inspection; check that the tires are fully inflated and not showing signs of damage, and check over the platform itself by looking at the platform and the surrounding rails. Never use a lift that shows kinds of damage in these areas. Be Mindful of the Weather Many people forget to check the current or coming weather before using a platform lift. The lift should not be used in winds over around twenty miles per hour, as it can become unsafe and dangerous. If you intend to use the lift for an afternoon’s work, have a quick check on the weather before starting. Never Use the Rail as a Crane You would be surprised at the amount of people who attach a chain or rope to the rails of the platform, then raise the platform to lift other items. This can be extremely dangerous, and can cause, in some cases, the lift to tip over. Don’t be tempted to use the lift to move items up on to the roof or to higher floors of the property; move them another way. Don’t Override Any Safety Features When you get a little accustomed to using the lift, it can be tempting to override some of the safety features of the lift. You may think that it will decrease the amount of time needed to complete the job, but this is a dangerous mistake to make. The safety features are there to protect you, and bypassing just one feature may have severe consequences. Position the Lift Correctly Where you park the lift has a direct impact on its safety, when being used. Assess the ground to ensure that there are no uneven slopes, holes or impediments that will prevent you from making a solid base for the platform. Also, don’t park the lift on soft ground, and if parking on a small incline, use the brakes and wooden chocks at each wheel to increase stability. Don’t try to reach out over the rails when up a platform lift, and never be tempted to use a ladder from the platform to allow you to gain extra height.

Why Hire A Processional Contractor For Large-Scale Painting Jobs

Posted by on Apr 13, 2015 in Uncategorized | 0 comments

Painting a bedroom of your home may not be very complicated, and you may be able to handle this job on your own, but for painting the exterior of a house or for any type of industrial painting, you want to consider hiring a professional contractor. There are many reasons why a contractor will typically be more skilled and the better option for painting any type of large-scale job and for any type of industrial painting.  1. Surfaces need to be prepped accordingly Prepping a surface for paint is a very large part of the actual job itself, but this needs to be done according to the surface material and the type of paint being used. For example, the exterior of your home may only need a good power washing to be ready for painting, but metal pieces used in an industrial setting may need to be scuffed for paint to adhere. Some surfaces may require a primer to make them level and even, whereas others can simply be painted on their own. A contractor will understand the various types of surfaces that need to be painted and how they should be treated so that the paint will adhere and give you the finish you need. 2. There are many different types of painting techniques Just as different surfaces need different types of prep work to be ready for paint, so the painting techniques will vary as well. Those metal surfaces that cannot be scuffed may need to be electroplated, meaning a charge of electricity is used to adhere the paint to the surface. Small pieces or those with extensive detailing may need to be sprayed rather than rolled or may need an actual paint bath to ensure every area is painted. When painting parts for a custom car, a professional painter may want to ensure it gets buffed and polished along with painted so it looks its best. 3. Cleanup and disposal are important parts of the job After the painting job is over, cleanup and disposal of the remaining paint will be important, and it’s good to ensure that these are done in a safe and eco-friendly way. A contractor may recycle paint that is remaining and will be able to touch up areas that are splattered by paint more easily than you could on your own. Rather than having old buckets of paint sitting in your garage or in your industrial facility, or having to pay someone to take those away for you, it’s good to hire a contractor who will do this as part of the overall work. For more information, contact a business such as Blast Pro Pty...

Cost Factors: Hiring A Commercial Civil Contractor

Posted by on Mar 16, 2015 in Uncategorized | 0 comments

Civil contractors are a fundamental part of development projects. It is important to hire a qualified professional who will offer assistance in the design, construction and management of commercial projects. There are different factors that you must consider when looking for a good contractor, including the experience, qualifications and licensing.  The financial implication of engaging the services is also a key factor, though it should not be the only primary factor in choosing the right firm for the job. It is imperative for you to understand the cost factors of civil contractors prior to the start of your commercial project. This will enable you to plan the budget more effectively and reduce cumulative expenses. Type of Engineering There are different specialist fields of civil engineering, including geotechnical, structural and water engineering. While all the fields are equally important, the cost will rise depending on the degree of precision required and the scope of development. For instance, in ideal circumstances, specialists who deal in sewer designs and intricate stormwater drainage structures will charge higher rates than general structural engineers. A civil engineer with extra architectural qualifications will also charge more than a contractor who has only majored in one field. It is vital to remember that you will make savings by hiring such an all-around professional as opposed to two separate experts. Property Size The size of the area being developed is directly proportional to the cumulative civil contractor charges for the project. Simple tasks such as the design and construction of access roads will become more demanding in large properties. A good strategy has to be developed to ensure that there is organization in the property. Moreover, the charges will also rise depending on the general configuration of the property. Irregularly shaped areas will require more work with regards to aspects such as utility infrastructure, so you should evaluate your options. Project Complexity The developments can be complex regardless of the engineering fields and the scope of the project. The terrain plays an important role in increasing the intricacy required in establishing constructions. For instance, if you want to construct a high-rise building on a steep slope, the civil contractor will be more engaged in surveys and tests to determine how best to attain structural integrity. It is important to consider such variables prior to the planning stage and to be forward with specifics in preliminary contractor meetings to avoid unforeseen charges. It is also advisable to avoid implementing phasing because it will mean discrete charges for each developmental stage. For more information, contact a business such as Sharpe Bros. (Aust)...

3 Reasons to Hire a Professional Excavating Service for Your Digging Job

Posted by on Feb 19, 2015 in Uncategorized | 0 comments

Whether it’s digging for a new septic tank on your private property or excavating to pour a foundation for new construction, you want to always hire a professional excavating service for the job. Trying to do any type of digging on your own, even for small jobs, can be a mistake. Consider the reason why, and the reason why it’s often even more cost-effective to hire professionals. 1. Professionals can adjust to ground conditions Never judge the ground by the topsoil, as you can hit any number of types of soil as you dig. This can include solid rock or very moist and muddy soil. A professional excavating crew will have the equipment and the skills to adjust, and will typically measure and inspect the ground before they even start digging. For rock, they may change to drills and machines that will chip away at the material rather than trying to actually dig it, and for very muddy soil, a hydrovac might be needed. This is a machine that actually vacuums the soil and all the moisture around it rather than just trying to scoop and dig it up. 2. Damage to surrounding structures and the environment can be minimized When digging yourself, you may use the largest machinery available so the work is quick and easy, but jackhammers used to cut through rock and heavy-duty backhoes can create vibrations that damage surrounding structures and the environment. A professional excavator such as Eichler Earthmovers Pty Ltd may be able to use equipment that is less disturbing, whether it’s the hydrovac mentioned above or a core drill that will cut through rock more readily than a jackhammer. This can be the preferred choice if you don’t want to cause cracks in the foundation of a home or see wildlife disturbed near new construction projects. 3. A professional company will have insurance If you handle your own excavating for a home project and were to cut a power line or break a water main, or otherwise damage your home or property, you would no doubt be liable for the cost of repairs. Rarely will a homeowner’s insurance policy cover the damage you cause yourself, and the cost of those repairs can often be much more than the cost of a professional company. Their expertise will no doubt lessen the risk of damage being done but in case this does happen, they will have an insurance policy that covers those costs and you will be...

How Can Old Gantry Cranes Be Upgraded?

Posted by on Jan 27, 2015 in Uncategorized | 0 comments

A gantry crane (a hoisting tool that is supported by a structure such as rails on the ground) can be upgraded if the owner so wishes. Gantry crane manufacturers say this can be done in several ways. This article discusses some of those ways. Remote Radio Controls Gantry crane manufacturers can provide software and systems to equip old gantry cranes with remote radio controls. This technology enables the operator of the gantry crane to operate it even when they are not physically present at the yard or factory where the crane is installed. Such capabilities can allow one operator to take charge of several gantry cranes since they do not have to be present where the crane is located in order to operate it. This can save you (the facility owner) labor costs. Variable Frequency Drives Old gantry cranes have controls that have only one speed setting for all lifting tasks. This leads various components of the gantry crane, such as the drive chains, to wear out quickly. This is because heavy loads put a lot of pressure on those components so it is better to move such loads slowly. However, old controls have only one speed setting so wear and tear is accelerated. Variable speed controls allow operators to slow down when moving heavy loads so that components can be shielded from the strain that wears them out quickly. Your gantry crane will need less maintenance (such as replacing worn parts) if you upgrade it so that it has these variable speed controls. Replacing Rubber Tires with Rails An old gantry crane that is mounted on rubber tires can be upgraded so that it runs on rails. This upgrade will enable it to lift heavier loads that the rubber tires could not sustain, and move them over longer distances. This is because gantry cranes can move way beyond the confines of rails since they have a beam-hoist that extends how far loads can be carried. Facility owners can benefit by having their equipment carry heavier payloads so the profitability of the business will go up. Before implementing any of the upgrades above, consult the gantry crane manufacturer or supplier so that you can be given the correct advice regarding the hardware and software that you need to implement the upgrade in a cost-effective way. If you don’t do that, you risk spending way beyond what you should have spent or you may compromise the safe functioning of your...
