阿特拉斯空压站设备结构与原理一、阿特拉斯空压机的机构和工作原理在压缩机的机体中，平行地配置着一对相互啮合的螺旋形转子。
通常把节圆外具有凸齿的转子，称为阳转子或阳螺杆。
把节圆内具有凹齿的转子，称为阴转子或阴转子。
一般阳转子与原动机连接，由阳转子带动阴转子转动。
转子上的最后一对轴承实现轴向定位，并承受压缩机中的轴向力。
转子两端的圆柱滚子轴承使转子实现径向定位，并承受压缩机中的径向力。
在压缩机机体的两端，分别开设一定形状和大小的孔口。
一个供吸气用，称为进气口；另一个供排气用，称作排气口。
螺杆压缩机的工作循环可分为进气，压缩和排气三个过程。
随着转子旋转，每对相互啮合的齿相继完成相同的工作循环。
螺杆式空气压缩机的核心部件是压缩机主机，是容积式压缩机中的一种，空气的压缩是靠装置于机壳内互相平行啮合的阴阳转子的齿槽之容积变化而达到。
转子副在与它精密配合的机壳内转动使转子齿槽之间的气体不断地产生周期性的容积变化而沿着转子轴线，由吸入侧推向排出侧,完成吸入、压缩、排气三个工作过程。
因此，双螺杆转子的型线技术决定着螺杆式空气压缩机产品定位的档次。
1、进气过程：转子转动时，阴阳转子的齿沟空间在转至进气端壁开口时，其空间最大，此时转子齿沟空间与进气口的相通，因在排气时齿沟的气体被完全排出，排气完成时，齿沟处于真空状态，当转至进气口时，外界气体即被吸入，沿轴向进入阴阳转子的齿沟内。
当气体充满了整个齿沟时，转子进气侧端面转离机壳进气口，在齿沟的气体即被封闭。
2、压缩过程：阴阳转子在吸气结束时，其阴阳转子齿尖会与机壳封闭，此时气体在齿沟内不再外流。
其啮合面逐渐向排气端移动。
啮合面与排气口之间的齿沟空间渐渐件小，齿沟内的气体被压缩压力提高。
3、排气过程：当转子的啮合端面转到与机壳排气口相通时，被压缩的气体开始排出，直至齿尖与齿沟的啮合面移至排气端面，此时阴阳转子的啮合面与机壳排气口的齿沟空间为0，即完成排气过程，在此同时转子的啮合面与机壳进气口之间的齿沟长度又达到最长，进气过程又再进行。

Oil-injected rotary screw compressors GA 180 - 315 (VSD+)Highest reliability, lowestoperating costsThe shortest route to maximize your profitability is to minimize youroperational costs. With up to 80% of a compressor lifecycle cost coming fromthe energy it consumes, this should be a clear focus. Atlas Copco's GAcompressors with SmartInjection enabled compression elements and IE4 orbetter class motors are designed to achieve significant energy savings whileproviding long and trouble-free life even in the harshest environmentalconditions.GA 180 – 315 (VSD+)EfficiencyAt the heart of the GA compressors are state-of-the-artcompression elements with SmartInjection technologyand high efficiency oil cooled IE4 or better class motors.This highly efficient drive train coupled with generouscooling capacity, low internal pressure drops and precisecontrol from the Elektronikon®Touch ensures optimumefficiency.ReliabilityThe GA compressor's drive train is IP66 rated protecting itcompletely from environmental dust and moistureensuring it can operate reliably in the toughest conditionsand at ambient temperatures up to 55°C/131°F.ServiceabilityService time is reduced to a minimum with all serviceparts grouped together for ease of access and, if greateraccess is required, the patented portal design enables fullaccess to all components. Each component has also beendesigned for serviceability, halving the time required toservice compared to traditional designs.3It's important to have high quality air, because contaminated air creates extra costs. It is better to avoid system contamination rather than deal with the consequences such as product spoilage, maintenance costs, replacing pipe work or leakages. Atlas Copco offers a range of quality air solutions.Clean air reduces operating costs.The GA 180-315 VSD+ is designed to deliver quality air.• Multiple smaller cartridges simplify and reduce service times and minimize oil carry over.• The GA full feature comes with an integrated dryer for greater air quality.• Guaranteed dewpoint of 3°C/37°F• Continuously monitored dew point.• New oil separator vessel with filter cartridges.Integrated air quality GA 180 – 315 (VSD+)Air dryersOur range of air dryers protect your systems and processes in a reliable, energy-efficient and cost-effective way.Protecting your systems and processesTreated air helps prevent pipework corrosion, product spoilage and premature failure of pneumatic equipment.Maintaining the quality of your end productA complete range of products with dew points from +3 to -70 °C to ensure the correct air quality for your application.Energy-efficient air dryersAll our air dryers are designed to perform in the most energy-efficient and environmentally friendly way.5Over 80% of a compressor’s lifecycle cost is taken up by the energy it consumes. Moreover, the generation of compressed air can account for more than 40% of a plant’s total electricity bill. To cut your energy costs, Atlas Copco pioneered Variable Speed Drive (VSD) technology in the compressed air industry. VSD leads to major energy savings, while protecting the environment for future generations. Thanks to continual investments in this technology, Atlas Copco offers the widest range of integrated VSD compressors on the market.LegendA =LossesB =Speed1 =Total losses traditional element2 =Total losses AC elementVariable Speed Drive (VSD)Atlas Copco's VSD technology closely follows the air demand by automatically adjusting the motor speed. This results in large energy savings of up to 35%. The Life Cycle Cost of a compressor can be cut by an average of 22%. In addition, lowered system pressure with VSD minimizes energy use across your production dramatically. Legend42% =Energy35% =Energy savings with VSD12% =Investment11% =MaintenanceVSD savings GA 180 – 315 (VSD+)Most production processes create fluctuating levels of demand which, in turn, can create energy waste in low use periods. Using the Elektronikon®unit controller, you can manually or automatically switch between two different setpoints to optimize energy use and reduce costs at low use times. In addition, the sophisticated algorithm runs the drive motor only when needed. As the desired setpoint is maintained while the drive motor’s run time is minimized, energy consumption is kept to a minimum.LegendA =Power consumptionB =TimeC =Energy SavingDual set-point and automatic stop• SmartInjection provides exact amount of oil required to element ensuring it always works at peak efficiency.• High efficiency IE4 (Fixed Speed) and IE5 (VSD+) motor.• Integrated energy recovery system recovers up to 78% of energy from integrated motor and element oil circuit.• Dual speed or VSD fan for energy efficiency in lower temperatures.Components designed for efficiencyThe Elektronikon®unit controller is specially designed to maximizethe performance of your compressors and air treatment equipmentunder a variety of conditions.

Choosing energy efficient compressors, paying special attention to the mix of compressors will be a major contributor to a smart AIR solution.Our sound proof design contributes to a better working environment around the compressors.Our compressors have been designed with maintenance in mind, reducing the downtime of machines and improving availability of compressed air.Compressed air demand of most applications varies widely. Adding one or multiple VSD compressors to the installation will greatly help to improve energy efficiency of the total installation, stability of compressed airpressure and reliability, thanks to more stable regime of each machine.Compressors generate heat. Adequate evacuation of this heat will ensure favorable working conditions for compressors and dryers alike.Even with a Variable Speed Drive compressor, having an appropriately sized buffer tank for compressed air will help smoothening the variation in demand and allow compressors to work in more stable operating conditions,thus helping both energy efficiency and reliability.Atlas copco has a wide air treatment portfolio thatmatches your needs.

Lubrication fluid is injected during the compression phase into the air. This not only reduces the wear of the elements but also cools them.The compressed air/oil mixture passes through a non-return valve to the oil separator element to separate the oil from the air.The wet compressed air, represented by the dark blue/ gree then passes through a minimum pressure valve and is cooled by an air-cooled aftercooler.Low noise axial cooling fans provide cooling air to the oil cooler and after cooler, ensuring satisfactory running temperatures as well as ventilating the compressor enclosure.1.Filtration & compression2.Air & oil separation3.Cooling15The condensed moisture is removed by a low pressure drop moisture separator and electronic condensate drain.This results in dry compressed air is that can be used in your application.Lubrication fluid contained in the oil receiver flows under differential pressure to a thermostatic bypass valve, air cooled oil cooler, high efficiency oil filter and oil stop valve before being injected into the compression element where it cools, seals and lubricates the compression process.The high efficiency oil filter provides superior filtration compared to conventional filters resulting in cleaner lubricant. The thermostatic bypass valve ensures that the compressor quickly reaches optimum operating temperature on start-up and maintains temperature during periods of low load by allowing cold lubricant tobypass the oil cooler.4.Moisture separator5.Oil flowGA 180 – 315 (VSD +)GA 180 - 315 (VSD+) (50 Hz)GA 180 - 5.5 bar 5.580 5.37769041.4146218070570012566640014110GA 180 - 7.5 bar7.51097.310658535.1124070GA 180 - 8.5 bar8.51238.312055833.5118267630013889 GA 180 - 10 bar101459.814251030.6108168GA 200 - 5.5 bar 5.580 5.377833.250.0176522071590013007650014330GA 200 - 7.5 bar7.51097.310672943.7154574 GA 200 - 8.5 bar8.51238.312068641.2145470 GA 200 - 10 bar101459.814262437.4132270GA 250 - 5.5 bar 5.580 5.37798559.1208726476600013228670014771GA 250 - 7.5 bar7.51097.310686852.1183975 GA 250 - 8.5 bar8.51238.312081749.0173171 GA 250 - 10 bar101459.814275445.2159871GA 315 - 7.5 bar7.510973106103662.2207232073620013669680014991GA 315 - 8.5 bar8.51238.312097858.7207273 GA 315 - 10 bar101459.814291154.7193070GA 200 VSD+ 8.5 bar8.51238.3120195-72512-43.5413-153622073500011023570012566GA 200 VSD+ 10 bar101459.8142193-66511.5-40409-140967510011244560012346GA 250 VSD+ 8.5 bar8.51238.3120195-86512-51.9413-183326471520011464580012787GA 250 VSD+ 10 bar101459.8142193-78211.5-47409-165775520011464580012787GA 315 VSD+ 8.5 bar8.51238.3120195-103212-61.9413-218732077520011464590013007GA 315 VSD+ 10 bar101459.8142193-95511.5-57.3409-202377520011464590013007 FAD(1) is measured at the following working pressures:5.5 bar (75 psi) version at 5 bar (73 psi)7.5 bar (100 psi) version at7 bar (100 psi)8.5 bar (125 psi) version at8 bar (125 psi)10 bar (150 psi) version at9.5 bar (150 psi)17Technical specifications GA 180 - 315 (VSD+) (60 Hz)GA 180 - 75 psi 5.580 5.37762237.3131824074600013228680014991GA 180 - 100 psi7.41077.210459635.8126376620013669 GA 180 - 125 psi9.11328.912953632.2113673GA 180 - 150 psi10.915810.715547928.7101575GA 200 - 75 psi 5.580 5.37783650.2177129577570012566640014110GA 200 - 100 psi7.41077.210473544.1155776 GA 200 - 125 psi9.11328.912966039.6139876 GA 200 - 150 psi10.915810.715559135.5125275GA 250 - 75 psi 5.580 5.37799159.5210035578590013007650014330GA 250 - 100 psi7.41077.210487952.7186277 GA 250 - 125 psi9.11328.912979147.5167674 GA 250 - 150 psi10.915810.715570142.1148575GA 315 - 100 psi7.41077.2104104362.6221043076600013228670014771GA 315 - 125 ps9.11328.912995057.0201376 GA 315 - 150 psi10.915810.715587352.4185076GA 200 VSD+ 125 psi9.11328.9129194-70611.6-42.3411-149629572500011023570012566GA 200 VSD+ 150 psi10.915810.7155190-63011.4-37.8403-133569GA 250 VSD+ 125 psi9.11328.9129194-84011.6-50.4411-178035570520011464580012787GA 250 VSD+ 150 psi10.915810.7155190-75511.4-45.3403-160073GA 315 VSD+ 125 psi9.11328.9129194-100411.6-60.2411-212743076530011684590013007GA 315 VSD+ 150 psi10.915810.7155190-91011.4-54.6403-192876(1) Unit performance measured according to ISO 1217, Annex C, Edition 4 (2009)Reference conditions:- Absolute inlet pressure 1 bar (14.5 psi).- Intake air temperature 20°C (68°F).(2) A-weighted emission sound pressure level at the work station, Lp WSA (re 20 μPa) dB (with uncertainty 3 dB).Values determined according to noise level test code ISO 2151 and noise measurement standard ISO 9614.(3) Integrated dryer (FF) : compressed air pressure dewpoint at dryer reference conditions 3°C (37°F).FAD(1) is measured at the following working pressures:75 psi version at73 psi73 psi100 psi version at100 psi100 psi125 psi version at125 ps125 psi150 psi version at150 psi150 psi Dimensionsmm inch mm inch mm inch GA 180 - 315 (VSD+) Pack (Air cooled)4390173209082202079 GA 180 - 315 (VSD+) Full Feature (Air cooled)5020198209082202079 GA 180 - 315 (VSD+) Pack (Water cooled)3130123209082202079 GA 180 - 315 (VSD+) Full Feature (Water cooled)3760148209082202079GA 180 – 315 (VSD+)Notes19Atlas Copco AB(publ) SE-105 23 Stockholm, Sweden Phone: +46 8 743 80 00Reg. no: 556014-2720 2935768©222,AtlasCopcoAirpowerNV,Belgium.Allrightsreserved.Designsandspecificationsaresubjecttochangewithoutnoticeorobligation.Readallsafetyinstructionsinthemanualbeforeusage.。
