What You Need To Know About Compressed Air Systems

Le 7 November 2018, 07:06 dans Humeurs 0

Compressed air is used in many operations and processes and as a source of energy for heating, ventilating, and air conditioning (HVAC) and process actuators and motors. It may also be supplied for low pressure systems and used for pneumatic control. Air can be compressed in several different ways and supplied at varying pressures and degrees of filtration depending on its use.


A typical compressed air system is capable of producing instrument quality air for pneumatic HVAC controls, tools, conveying systems, and general plant air. The system consists of a single motor driven single stage rotary screw compressor with inlet air filter, a safety relief valve, aftercooler, air/oil separator, air receiver with safety relief valve, prefilter, air dryer, afterfilter, oil/water traps, and oil/water separator.


Compressors are most often supplied skid mounted as a packaged unit.Theassembled package includes all major components, controls, and a sound attenuation enclosure. The unit only requires mounting to a foundation,hook up to system piping, connection to the oil water separator, and power connection.


There are various types of compressors: Rotary helical screw air compressors are positive displacement machines. Atwin-screw compressor consists of accurately matched rotors [one lobe (male) and one helix (female)] that mesh closely when rotating within a close tolerance common housing. One rotor is motor driven while the other is gear driven, turning it in a counter-rotating motion.


The rotors uncover inlet posts at one end allowing air to flow in. As the rotors continue to rotate the air is compressed by the minishing volume between the rotors . At the end of the rotors, ports allow the now compressed air to exit. One or more stages may be used.


These compressors are used in systems up to 3000 cubic feet per minute (cfm). They are usually oil injected to increase sealing, lubricate rotors, and provide cooling. They can also be oil free. One or two stages can be used. They have


a low initial cost, no pulsation, are almost free of vibration, and do not require special foundations.


Centrifugal compressors compress air as it enters the center of a fluted casting, housing a rotating impeller. The impeller imparts kinetic energy to the gas which turns into potential energy as the gas velocity slows, thus increasing pressure Launch CReader 9081. Compression is a continuous process. One or more stages may be used.


Centrifugal compressors are used in large systems up to 15,000 cfm. A blow-off silencer is needed to control noise. Centrifugal compressors require no ubrication in contact with the air stream and therefore provide oil free air.


Reciprocating or positive displacement compressors use a piston in a cylinder to compress air up to a capacity of 6,000 cfm Autel MaxiSys MS908. Air enters the cylinder through a valve when the piston is going down. The valve closes when the piston starts to go up. As the piston approaches the top ofthe cylinder, the air is compressed by the decreasing volume. An exhaust valve opens when the piston is near the top of the cylinder allowing the compressed air to exit. The cycle is them repeated.


Rotary sliding vane compressors use a rotor eccentrically mounted in a cylinder. The rotor has eight or more slots cut along its length .Vanes are placed in the slots. As the rotor rotates, the vanes move out from centrifugal force. As the rotor continues through a rotation, the rotor housing causes the vanes to move back in the slot ofthe rotor.


The volume of air between the housing, eccentrically mounted rotor, and two vanes changes as the rotor rotates, compressing the air.

Air compressors are used in many operations and processes and as a source of energy for heating,ventilating, and air conditioning.

What To Look For In A Salvage Car Auction

Le 9 October 2018, 04:12 dans Humeurs 0

A salvage car auction may be also advertised as insurance car auction. What you should know is that a salvage car auction has absolutely nothing to do with the normal auctions - public, government or wholesale.


Salvage car auction venues offer cars that have been collected and rebuilt by the insurance companies in some cases, while in order they are sold in their damaged condition. Normally you can reach a price with 20% to 50% cheaper than the regular price of the car you are looking for. In some cases, the cars being sold at salvage car auction places might have just a minor problem but in most of the cases, these cars have suffered a serious damage.


The main problem with cars being sold at a salvage car auction is that these cars are usually damaged to an extend that a regular car buyer cannot properly asses. That is why it is strongly recommended that only experienced professionals buy from these auctions. If you are not one OBD Tool, than get somebody along with you when going to bid on a salvage car auction. On the other hand, if you are looking for a car just because of the spare parts than you should not care that much. Just check if the parts you are interested in are in order and of course be careful with the price you will have to pay. As you may guess, there is no need to pay a prices closer to the regular price of the spare parts you are buying the car for.


For the same reason described above is a must that you perform a proper check of the car you want to purchase and second - to check the vehicle history report. A car might look in good condition but it might has been seriously rebuild or repaired in a way that will cause you troubles later. Even after you have repaired the car, you should ask for a complete check by a car company to ensure that all in your car is in complete order.


The rest of the usually checks that are done when buying a car are still a must - you should read carefully all the paperwork involved, check the VIN numbers and the car history.


Be prepared for the inconveniences that you might experience later in case you have bough a rebuilt car from a salvage car auction. The fact that a car has been rebuilt stays in its record. Cars that have been rebuilt are not favorite to insurance companies or banks. In addition, even if the car you are purchasing is still under the manufacturers warranty period, this warranty might be voided in case the car has been rebuilt. So never, rely on the fact that "the car is still in the warranty period..."


Finally, this is what we would advise the regular car hunters - try another car auction and leave the salvaged car auction venues to the professionals. It is worth neither the hassle nor the risk buying from a salvaged car auction just to save a minor amount of money Autel MaxiSys MS908.
