Abstract
The utility model discloses 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, be seal space between described rotor and stator, described air outlet is arranged at housing side, and described anti-rotation slip ring is arranged between movable orbiting scroll and main bearing.Because described centrifugal compressor have employed movable orbiting scroll, static vortex disk to connect rotor, have low noise, form structure is simple, and can improve the advantage of energy conversion efficiency.
Description
Technical field
The utility model 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 special wide, such as: air-conditioning, blower, dry gas sealing device.The centrifugal compressor of current field of air conditioning, adopts fixed AC motor or frequency-conversion alternating current motor frequently, and by overdrive gear, rotating speed is brought up to design speed and carry out impeller rotation, the impeller of High Rotation Speed to air work, thus improves gas pressure.In order to the change making compressor adapt to Smaller load, before the impeller vane throttling device can be set in face, open large by blade and turn down the flow area changing inlet, reaching the object of adjust flux.The deficiency of the compressor of this structure is: the existence of gear-box considerably increases the form structure of compressor, and make casing seem huge, heavy, 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 problems to be solved in the utility model is to provide a kind of low noise, and form structure is simple, and can improve the centrifugal compressor of energy conversion efficiency.
For solving the problem, the utility model 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 is seal space between described rotor and stator, 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, are provided with black box between described rotor and stator.
The beneficial effect of the utility model centrifugal compressor is: because described centrifugal compressor have employed movable orbiting scroll, static vortex disk to connect rotor, have low noise, and 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 utility model.
Embodiment
Consult shown in Fig. 1, the utility model 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, be seal space between described rotor 10 and stator 6, described air outlet 12 is arranged at housing 13 side, 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, is provided with black box between described rotor 10 and stator 6.
Gas enters housing 13 from intakeport 1, main bearing 5 is by bent axle 11 rotor driven 10 High Rotation Speed, rotor 10 impeller (not shown), impeller makes to enter the gas of housing under the influence of centrifugal force, pressure and speed increase to some extent, flow in the breathing pipe of the gas after pressurization in housing (not shown), reduce in gas velocity above, 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 the utility model centrifugal compressor is: because described centrifugal compressor have employed movable orbiting scroll, static vortex disk to connect rotor, have low noise, and form structure is simple, and can improve the advantage of energy conversion efficiency.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
