To just contacting the classmate of pneumatics machine and compressor, classics regular meeting has a wrong idea: Pneumatics machine is compressor. Actually otherwise, Pneumatics machine and compressor are two kinds of different mechanical products actually, although they are put in particular general character and connection.

1. Intake process: When rotor is rotational, when the space of roller seating space of rotor of yin and yang is turning to wall of the end that take energy of life to start to talk, its space is the largest, right now space of rotor roller seating space is interlinked with what present gas opening, because of the gas in the roller seating space when exhaust by complete eduction, when exhaust is finished, roller seating space is in vacuum condition, when turning to the mouth that take energy of life, outside gas namely by inspiratory, inside the roller seating space that enters rotor of yin and yang along axial. When gas filled whole roller seating space, rotor turns to present gas opening from housing into gas side end panel, be closed namely in the gas of roller seating space. 2, 3. Reduce a process: Rotor of yin and yang is when inspiratory end, crown of rotor of its yin and yang can close with housing, right now gas is inside roller seating space no longer outflow. Face of its clench the teeth carries shift to exhaust gradually. The space of roller seating space between face of clench the teeth and vent gradually small, the gas inside roller seating space is compressed pressure increases. 4. Exhaust process: When the end panel of clench the teeth of rotor turns to be interlinked with housing vent, compressed8 gas begins eduction, till the scale of clench the teeth of crown and roller seating space moves,come exhaust end panel, right now the space of roller seating space of the face of clench the teeth of rotor of yin and yang and housing vent is 0, complete exhaust process namely, at the same time here the face of clench the teeth of rotor and housing enter the length of roller seating space between gas mouth to be achieved again the longest, intake process undertakes again again. The working principle of craft compressor: It is with common centrifugal type compressor exemple, turbine (or electromotor) drive impeller of compressor main shaft to turn, below centrifugal force effect, gas is swung go in the diffuser at the back of working annulus. And rare district is formed among working annulus, the gas in front from the job annulus the part taking steam among enters impeller, because working annulus rotates ceaselessly, morale physical ability is swung continuously to go out, maintained the continuous flow of the gas in baric machine thereby. Gas increased pressure because of centrifugation, OK still very old rate leaves working annulus, aeriform classics diffuser lowered rate gradually, kinetic energy change is static pressure can, increased pressure further. If a pressure that working impeller gets is insufficient still, the method that can work through making multistage impeller series connection rises will achieve the requirement to outlet pressure. The series connection between class passes a turn to connect, circumfluence implement will come true. This is the working principle of centrifugal type compressor. The business that both company condition does pneumatics plane is very much, but the business that does craft compressor is not much. The enterprise of craft compressor can be produced commonly different the unit that reduces craft. Craft compressor produces a business: 1. Shaanxi air-blower (group) limited company only then built 1968, built go into operation 1975. The product that short for Shaanxi Province rouses and service apply extensively at oil, chemical industry, metallurgy, empty cent, electric power (include nuclear report) , city building (the subway) , the environmental protection, pharmacy, pillar industry domain that builds the national economy such as the road. Beat of short for Shaanxi Province is the systematic solution business that basically provides distributed the sources of energy to the user and systematic service business, formed ” energy changeover equipment is made, operation of infrastructure of industrial service, energy ” Wu of 3 great undertaking board piece. Among them, the first board piece energy changeover equipment is made include energy of compressor of of all kinds turbine, air-blower, fanner, industry to reclaim boiler of appearance of turbine, turbine, instrument, industry, for military use changes his costume or dress machinery of car, road surface. Shen Gu has base of experiment of national level compressor, testing stand of compressor of Shenyang beat group has 30 thousand kilowatt to light drive of turbine of drive of drive, report of 50 thousand kilowatt, 100 thousand kilowatt amain movement of total pressure full load and steam use function power of test, it is home unique, have international to precede large turbine compressor of the level experiments base. Pneumatics machine produces a business: The well-known pneumatics aircraft company on the world: Sweden power of life of Suo Lan of case of Atelasi, United States flower, United States (be stood to buy by Japanese day) etc. Exemple: Of course, company of aircraft of famous compressor, pneumatics still has a lot of, did not list one by one here, hope today’s content can be helped somewhat to everybody.
