Some Information about Compressed Air System

According to PneumaticTips, it’s important to remember that, if you consider the overall cost of ownership of a compressed air system, assuming a ten-year life for the system, the purchase cost only accounts for about 12% of the total. Furthermore, 76% of the cost of owning a compressed air system comes in the form of electricity bills.
To put this in perspective, if you continuously run a 100-hp compressor at full power, you will spend $74,000 a year in energy costs, assuming a rate of 10 cents per kWh.

Therefore, if you are assessing the value of your compressed air system and making your decision in purely economic terms, you need to keep the total cost of ownership in the forefront of your mind. While the cost of repairs may be significantly less than the cost of replacing your system, ask yourself if you’re keeping a system working that’s actually costing you more in the long run by operating less efficiently.

These costs come in many different forms. First, as compressors age, the costs of repairs increase. That’s why you should carefully consider any repair that costs over 50% of the cost of a comparable replacement. But you also need to consider the operational inefficiencies and the subsequent costs of an older compressor. Because of how inefficient some older models are, you may be wasting as much money on energy costs as you would spend on a new dental compressor.

Many operational malfunctions can be traced back to the power source. Are there issues with the point of connection between your compressor and the electric grid? Additionally, improper lubricant levels can contribute to poor operation. When was the last time you checked and adjusted the oil levels in your system?

If you are experiencing excessive noise or knocking while the compressor is running, loose bearings, flywheels, belts or defective crankcases are also possible culprits. If you can isolate the source of the noise, you can either make the small adjustments necessary or at least guide a repair technician in the right directions, potentially saving you money on otherwise costly repairs.

Choosing a Right Dental Compressor

The most popular compressors are positive displacement compressors, which work by filling a chamber with air and then reducing volume. Positive displacement compressors include reciprocating, rotary screw and rotary vane compressors. Although reciprocating compressors are the most widely available on the market, rotary compressors are most useful in industrial environments.

Air compressors are a substantial investment for business owners, so the process of purchasing one requires consideration of many factors.

considerations should help you choose the right air compressor system for your business:

    Buying a dental compressor that’s too small can waste time, due to waiting for pressure to build up, and using a compressor that’s too big can waste resources.

    Select an air compressor that provides enough airflow. A compressor’s airflow is measured in cubic feet per minute (CFM). The air compressor’s CFM output should be greater than the operational CFM requirement and less than the maximum CFM output. A half-inch wrench, for example, requires 5 CFM at 90 pounds per square inch (psi), which means the CFM output should be greater to ensure proper performance with the tool. A good rule of thumb is to add 30 percent to the determined CFM number. Adding all the air tools to be used in a work day, however, may result in an inflated CFM number.

     If you need to stop using a tool to wait for pressure to build, the compressor may be too small. Note that continuous-use tools will have higher CFM requirements than intermittent-use tools. Higher pressures and volumes will naturally require increased horsepower, electrical components and larger pumping systems. When considering a compressor, actual cubic feet per minute (ACFM) will provide a more accurate measurement of usable air.

    Know your work environment. Knowing this will help determine whether the drive system should be an electric motor or a gasoline engine. Electric motors are less expensive and require less maintenance. Gasoline engines offer increased portability.

    Determine the size of the compressor tank. This depends on the overall nature of the usage. A small tank should prove sufficient for quick, concentrated bursts of usage. Sustaining longer periods of use will require a larger tank.

    Determine the tools needed. If you know which tools you need for your business, it will help determine how many psi the compressor should be able to provide.

    Determine the horsepower needed. This information will ensure the compressor can produce enough air. A machine with high horsepower but low CFM will run hot in a shorter service life.

    Consider your control systems. Start/stop systems are helpful for work that doesn’t require continuous air. Constant speed control is ideal if expecting more than six to eight starts per hour. Dual control uses an auxiliary valve that permits a choice between start/stop and constant speed.

    Use the right protection. If using a compressor outside, it will need protection against water and extreme temperatures. Cast-iron construction will ensure added reliability and durability.

    Consider other features in addition to tank size, pressure and airflow. Stainless steel finger valves will eliminate corrosion. Oil-monitoring devices prevent damage caused by low oil levels. One-piece connecting rods eliminate many internal adjustments. Keep in mind that fewer parts will reduce maintenance costs.

The Reason Why Dentists Choose Dental X-rays

Dental radiography has evolved from film and chemical developers into a highly technical process that involves various types of digital x-ray machines, as well as powerful dental software programs to assist the dentist with image acquisition and diagnostic analysis of the acquired images. When making the decision to purchase x-ray equipment, the doctor needs to research the available options thoroughly, in order to make an informed choice for the “right” machine for his or her practice.

Dental X-rays are one of the most important part of your regular dental treatment. Your dentist uses the specialized imaging technology to look for hidden tooth decay – also called cavities – and can show dental issues such as abscessed teeth, dental tumors, and cysts.

Additionally, your dental X-rays allow your dentist to see the condition of prior dental procedures, such as fillings, crowns, root canals, and bridges. And, too, your dentist will be able to look for possible bone loss as a result of periodontal gum disease and find hidden tartar build up.

Your dentist or the dental tech inputs the command for the portable dental x rays unit to send a X-ray through your teeth and into the sensor, effectively taking a photo of your tooth or teeth. The sensor captures the resulting image and sends it through the wire to the computer. Then your dentist will reposition the sensor and take additional digital X-rays until all of your teeth have been X-rayed.

With digital dental X-rays, your dentist or other dental professional is able to immediately see your teeth and jaw bones. This means that assessment and diagnosis is virtually instantaneous.

Most of the earliest X-rays depended on photographic films to capture the images and make them readable. Digital detectors skip this step; rather than using light beamed through objects onto film, it allows for digital scanning and image interpretation. In terms of radiation the two are about the same initially, though digital versions typically have a shorter exposure time and as such tend to be more efficient.

Important Facts about Dental Implants

Up until fairly recently, most dentists relied on procedures such as root canals, bridges and the use of dentures as the best methods of fixing lost or broken teeth. While these methods have always been effective in some cases, for many people they did not provide a viable, long-term solution. Root canals( root canal treatment equipment ) and bridges fail over time and dentures have proven to be uncomfortable and cumbersome to wear and use for many people. It is only through the development of methods, tools and technology that a better way to replace damaged or lost teeth has come along. The use of dental crowns and dental implants has become much more commonplace today and provide you with the best option for your teeth.

When you are considering a procedure like this, it is important that you know just what an implant is so you know what to expect as a result of the procedure. A dental implant is a device that has been particularly fabricated and manufactured to act like and look like your own teeth. The implant will take the place of a missing or damaged tooth in your mouth. The tooth is often made of a combination of titanium and other materials and is designed to look and feel just like a normal tooth would.

The procedures needed to put in a dental implant can take some time. It is a surgical procedure that you can have performed. The procedure involves placing an implant into your upper or lower jaw, wherever the implant is required. A screw is then positioned into the implant area and the gum tissue replaced over the implant to help secure it into place. This first step is then allowed to heal properly before the next step occurs, where a post gets placed so that the artificial tooth (which is the dental crown), can be affixed securely to it in the implant, giving you the tooth you want.

The implant will act just like your normal teeth would and no one will be able to tell the difference by looking at you. The implants, unlike your other teeth, will not wear over time and can be brushed and treated just as you would any other tooth that you have. As long as the other teeth around the implant are healthy ones, you will not have any problems at all.

Recurrent caries is tooth decay that occurs under an existing filling or other dental work, such as a bridge. It might be caused by poor oral hygiene or by the development of a microscopic pathway for leakage past the restoration (microleakage). Depending on how bad the decay is, treatment will probably involve fillings, inlays, veneers, or crowns. If the decay has reached the inner core of the tooth, you may require root canal treatment to eliminate the bacteria. If the tooth with recurrent caries needs to be extracted, then dental implants, fixed bridgework, or removable dentures are possible options.
