A compressor is a mechanical device that increases the Compressors are similar to Many compressors can be staged, that is, the fluid is compressed several times in steps or stages, to increase discharge pressure. Often, the second stage is physically smaller than the primary stage, to accommodate the already compressed gas without reducing its pressure. Each stage further compresses the gas and increases its pressure and also temperature if inter cooling between stages is not used.

[ vague] Put another way, a positive displacement コンプレッサー is one that operates by drawing in a discrete volume of gas from its inlet then forcing that gas to exit via the compressor's outlet. The increase in the pressure of the gas is due, at least in part, to the compressor pumping it at a mass flow rate which cannot pass through the コンプレッサー at the lower pressure and density of the inlet. A This type of compressor can コンプレッサー a wide range of gases, including refrigerant, hydrogen, and natural gas. Because of this, it finds use in a wide range of applications in many different industries and can be designed to a wide range of capacities, by varying size, number of cylinders, and cylinder unloading. However, it suffers from higher losses due to clearance volumes, resistance due to discharge and suction valves, weighs more, is difficult to maintain due to having a large number of moving parts, and it has inherent vibration. Ionic liquid piston compressor [ ] Main article: Rotary screw compressors use two meshed rotating positive-displacement The classifications of rotary screw compressors vary based on stages, コンプレッサー methods, and drive types among others. [ clarification needed] and the selection of air drier is always 1. 5 times volumetric delivery of the compressor. Designs with a single screw Screw compressors have less moving components, larger capacity, less vibration and surging, can operate at variable speeds, and typically have higher efficiency. Small sizes or low rotor speeds are not practical due to コンプレッサー leaks caused by clearance between the compression cavities or screws and compressor housing. Rotary vane compressors [ ] See also: Rotary vane compressors コンプレッサー of a rotor with a number of blades inserted コンプレッサー radial slots in the rotor. The rotor is mounted offset in a larger housing that is either circular or a more complex shape. As the rotor turns, blades slide in and out of the slots keeping contact with the outer wall of the housing. With suitable port connections, the devices may be either a compressor or a vacuum pump. They can be either stationary or portable, can be single or multi-staged, and can be driven by electric motors or internal combustion engines. Dry vane machines are used at relatively low pressures e.2bar or 200kPa or 29psi for bulk material movement while oil-injected machines have the necessary volumetric efficiency to achieve pressures up to about 13bar 1,300kPa; 190psi in a single stage. A rotary vane compressor is well suited to electric motor drive and is significantly quieter in operation than the equivalent piston compressor. Rolling piston [ ] The Rolling piston in a rolling piston style compressor plays the part of a partition between the vane and the rotor. 2 of these compressors can be mounted on the same shaft to increase capacity and reduce vibration and noise. In refrigeration and air conditioning, this type of compressor is also known as a rotary compressor, コンプレッサー rotary screw compressors being also known simply as screw compressors. But its structure does not allow capacities beyond 5 refrigeration tons, is less reliable than other compressor types, and is less efficient than other compressor types due to losses from the clearance volume. Scroll compressors [ ] Main article: A scroll compressor, also known as scroll pump and scroll vacuum pump, uses two interleaved spiral-like vanes to Often, one of the scrolls is fixed, while the other orbits eccentrically without rotating, thereby trapping and pumping or compressing pockets of fluid between the scrolls. Due to minimum clearance volume between the fixed scroll and the orbiting scroll, these compressors have a very high These compressors are extensively used in air conditioning and refrigeration because they are lighter, smaller and have fewer moving parts than reciprocating compressors and they are also more reliable. They are more expensive though, so peltier coolers or rotary and reciprocating compressors may be used in applications where cost is the most important or one of the most important factors to consider when designing a refrigeration or air conditioning system. This type of compressor was used as the When compared with reciprocating and rolling piston compressors, scroll コンプレッサー are more reliable since they have fewer components and have a simpler structure, are more efficient since they have no clearance volume nor valves, and possess the advantages both of surging less and not vibrating so much. But, when compared with screw and centrifugal compressors, scroll compressors have lower efficiencies and smaller capacities. Diaphragm compressors [ ] Main article: A diaphragm compressor also known as a membrane compressor is a variant of the conventional reciprocating compressor. The compression of gas occurs by the movement of a flexible membrane, instead of an intake element. The back and forth movement コンプレッサー the membrane is driven by a rod and a crankshaft mechanism. Only the membrane and the compressor box come in contact with the gas being compressed. The degree of flexing and the material constituting the diaphragm affects the maintenance life of the equipment. Generally stiff metal diaphragms may only displace a few cubic centimeters of volume because the metal can not endure large degrees of flexing without cracking, but the stiffness of a metal diaphragm allows it to pump at high pressures. Rubber or silicone diaphragms are capable of enduring deep pumping strokes of very high flexion, but their low strength limits their use to low-pressure applications, and they need to be replaced as plastic embrittlement occurs. Diaphragm compressors are used for hydrogen and compressed natural gas Main article: Centrifugal compressors use a rotating disk or This type of compressor, along with screw compressors, are extensively used in large refrigeration and air conditioning systems. Magnetic bearing magnetically コンプレッサー and air bearing centrifugal compressors exist. But, their initial cost is higher, require highly precise Diagonal or mixed-flow compressors [ ] Diagonal or Axial compressors [ ] Main article: Axial compressors are dynamic rotating compressors that use arrays of fan-like The arrays of airfoils are set in rows, usually as pairs: one rotating and one stationary. The rotating airfoils, also known as blades or rotors, accelerate the fluid. The stationary airfoils, also known as stators or vanes, decelerate and redirect the flow direction of コンプレッサー fluid, preparing it for the rotor blades of the next stage. The motor is designed to operate in, and be cooled by, the refrigerant gas being compressed. Open compressors have an external motor driving a shaft that passes through the body of the compressor and rely on rotary seals around the shaft to retain the internal pressure. The difference between the hermetic and semi-hermetic, is that the hermetic uses a one-piece welded steel casing that cannot be opened for repair; if the hermetic fails it is simply replaced with an entire new unit. A semi-hermetic uses a large cast metal shell with gasketed covers with screws that can be opened to replace motor and compressor components. The primary advantage of a hermetic and semi-hermetic is that there is no route for the gas to leak out of the system. The main advantages of open compressors is that they can be driven by any motive power source, allowing the コンプレッサー appropriate motor to be selected for the application, or even non-electric power sources such as an An open pressurized system such as an automobile air conditioner can be more susceptible to leak its operating gases. Open systems rely on lubricant in the system to splash on pump components and seals. If it is not operated frequently enough, the lubricant on the seals slowly evaporates, and then the seals begin to leak until the system is no longer functional and must be recharged. By comparison, a hermetic or semi-hermetic system can sit unused for years, and can usually be started up again at any time without requiring maintenance or experiencing any loss of system pressure. Even well lubricated seals will leak a small amount of gas over time, particularly if the refrigeration gasses are soluble in the lubricating oil, but if the seals are well manufactured and maintained this loss is very low. The disadvantage of hermetic compressors is that the motor drive cannot be repaired or maintained, and the entire compressor must be replaced if a motor fails. A further disadvantage is that burnt-out windings can contaminate the whole systems, thereby requiring the system to be entirely pumped down and the gas replaced This can also happen in semi hermetic compressors where the motor コンプレッサー in the refrigerant. Typically, hermetic compressors are used in low-cost factory-assembled consumer goods where the cost of repair and コンプレッサー is high compared to the value of the device, and it would be more economical to just purchase a new device or compressor. A hermetic compressor is simpler and cheaper to build than a semi-hermetic or open compressor. One common way of cooling the gas during compression is to use cooling jackets around the casing of the compressor. Compressors in ideal thermodynamic cycles [ ] Ideal Ideal Ideal Ideal Ideal Ideal NOTE: The isentropic assumptions are only applicable with ideal cycles. Real world cycles have inherent losses due to inefficient compressors and turbines. The real world system are not truly isentropic but are rather idealized as isentropic for calculation purposes. Staged compression [ ] In the case of centrifugal compressors, commercial designs currently do not exceed a compression ratio of more than 3. 5 to 1 in any one stage for a typical gas. Since compression raises the temperature, the compressed gas is to be cooled between stages making the compression less adiabatic and more isothermal. The inter-stage coolers intercoolers typically result in some partial コンプレッサー that is removed in In the case of small reciprocating compressors, the compressor flywheel may drive a cooling fan that directs ambient air across the Because rotary screw compressors can make use of cooling lubricant to reduce the temperature rise from compression, they very often exceed a 9 to 1 compression ratio. For instance, in a typical diving compressor the air is compressed in three stages. Gas• In automobiles and other types of vehicles including piston-powered airplanes, boats, trucks, etc.diesel or gasoline engines power output can be increased by compressing the intake air, so that more fuel can コンプレッサー burned per cycle. These engines can power compressors using their own crankshaft power this setup known as a Lubrication [ ] Compressors that are driven by an electric motor can be controlled using a Applications [ ] Gas compressors are used in various applications where either higher pressures or lower volumes of gas are needed:• In maritime cargo transport and cargo operations by• Petroleum refineries, natural gas processing plants, petrochemical and chemical plants, and similar large industrial plants require compressing for intermediate コンプレッサー end-product gases.
