Abstract
The invention discloses a centrifugal compressor which comprises an air suction opening, a dynamic vortex plate, a fixed vortex plate, a self-rotating-resisting sliding ring, a main bearing, a stator, a lower shell, a base, a partitioning plate, a rotor, a crankshaft, an air outlet and a shell body. The air suction opening is formed in the top of the shell body. The shell body is fixed on the lower shell which is placed on the base. A sealed space is formed between the rotor and the stator. The air outlet is formed in the side face of the shell body. The self-rotating-resisting sliding ring is placed between the dynamic vortex plate and the main bearing. The dynamic vortex plate and the fixed vortex plate are used for being connected with the rotor, so that the centrifugal compressor has the advantages of being low in noise and simple in appearance structure, and energy converting efficiency can be improved.
Description
Technical field
The present invention relates to a kind of centrifugal compressor.
Background technique
Along with the accelerated development of national economy and advancing by leaps and bounds of science and technology, fluid machinery also obtains continuous development and perfection thereupon.At present, in the middle of the development trend of fluid machinery is gone into the thick of life gradually.Centrifugal compressor is in life, and especially chemical plant, oil refinery, power station etc. use spy wide, such as: air-conditioning, blower, dry gas sealing device.The centrifugal compressor of field of air conditioning, adopts fixed AC motor or frequency-conversion alternating current motor frequently at present, by overdrive gear, rotating speed is brought up to design speed and comes impeller to rotate, and the impeller of High Rotation Speed is to air work, thus raising gas pressure.In order to make compressor adapt to the variation of little load, blade throttling arrangement can be set before impeller, by blade, open large and turn down the flow area that changes inlet, reach the object of adjust flux.The deficiency of the compressor of this structure is: the existence of gear-box has increased the form structure of compressor greatly, makes casing seem huge, heavy, and cost also increases thereupon; The rotating speed of centrifugal compressor is very high, and the speedup process noise of gear is very large.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of low noise, and form structure is simple, and can improve the centrifugal compressor of energy conversion efficiency.
For addressing the above problem, the present invention adopts following technological scheme: a kind of centrifugal compressor, comprise intakeport, movable orbiting scroll, static vortex disk, anti-rotation slip ring, main bearing, stator, lower casing, base, dividing plate, rotor, bent axle, air outlet and housing, described intakeport is arranged at the top of housing, described housing is fixed on lower casing, described lower casing is arranged on base, it between described rotor and stator, is seal space, described air outlet is arranged at housing side, and described anti-rotation slip ring is arranged between movable orbiting scroll and main bearing.
As preferably, described rotor is connected with main bearing by bent axle, and described dividing plate is arranged between rotor and lower casing.
As preferably, described housing and lower casing form seal space, between described rotor and stator, are provided with black box.
The beneficial effect of centrifugal compressor of the present invention is: because described centrifugal compressor has adopted movable orbiting scroll, static vortex disk, connect rotor, have low noise, form structure is simple, and can improve the advantage of energy conversion efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of centrifugal compressor of the present invention.
Embodiment
Consult shown in Fig. 1, the present invention adopts following technological scheme: a kind of centrifugal compressor, comprise intakeport 1, movable orbiting scroll 2, static vortex disk 3, anti-rotation slip ring 4, main bearing 5, stator 6, lower casing 7, base 8, dividing plate 9, rotor 10, bent axle 11, air outlet 12 and housing 13, described intakeport 1 is arranged at the top of housing 13, described housing 13 is fixed on lower casing 7, described lower casing 7 is arranged on base 8, between described rotor 10 and stator 6, it is seal space, described air outlet 12 is arranged at housing 13 sides, described anti-rotation slip ring 4 is arranged between movable orbiting scroll 2 and main bearing 5.
Described rotor 10 is connected with main bearing 5 by bent axle 11, and described dividing plate 9 is arranged between rotor 10 and lower casing 7, and described housing 13 forms seal space with lower casing 7, between described rotor 10 and stator 6, is provided with black box.
Gas enters housing 13 from intakeport 1, main bearing 5 is by bent axle 11 rotor driven 10 High Rotation Speeds, rotor 10 impeller (not shown), impeller makes the gas that enters housing under the effect of centrifugal force, pressure and speed increase to some extent, in the breathing pipe (not shown) of the gas after pressurization in housing, flow, and the gas velocity above reduces, before gas below is constantly poured into, the kinetic energy of gas has changed into again pressure energy.Further play pressurization.
The beneficial effect of centrifugal compressor of the present invention is: because described centrifugal compressor has adopted movable orbiting scroll, static vortex disk, connect rotor, have low noise, form structure is simple, and can improve the advantage of energy conversion efficiency.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
