Abstract
The utility model relates to a linkage device for a plurality of adjustable inlet guide vanes and an adjustable diffuse of a centrifugal refrigeration compressor, belonging to large-sized refrigeration equipment field, which is characterized in that an eccentric wheel (2) and a plurality of adjustable inlet vanes (7) arranged inside a casing (10) are arranged on an output shaft of a stepping motor (1) arranged on the casing (10), a guide rod (4) with a spring (3) is arranged in the other inner ring groove of a diffuse (5), a plurality of threads meshed with a locknut (9) are arranged at the other end of the guide rod (4), and the eccentric wheel (2) is assembled in the same plane with the shaft axis of the guide rod (4). The diffuse employed by the centrifugal refrigeration compressor in prior art is nonadjustable and the adjustable guide vanes and the diffuse can only be adjusted separately. The utility model has the advantages that the structure is simple, the linkage of the adjustable inlet guide vanes and the adjustable diffuse of the centrifugal refrigeration compressor is realized, the match of the adjustable inlet guide vanes and the adjustable diffuse is more accurate, the unit operation efficiency is higher and the problem that the unit fails to surge in the case of small opening of the adjustable inlet guide vanes is solved effectively.
Description
One. technical field
The utility model relates to a kind of centrifugal refigerating compressor in the large-scale chiller plant, adopts import adjustable vane and adjustable Diffuser linkage.
Two. background technique
Existing centrifugal refigerating compressor all adopts import adjustable vane mechanical structure, controls the gas flow that enters in the refrigeration compressor, and the refrigerating capacity of unit is changed.Simultaneously, when unit starting, strengthen the aperture of stator gradually, motor load is progressively increased, prevent that the electric motor starting electric current is excessive and damage; Flow out through Diffuser in the impeller of high speed rotating, its flow area progressively strengthens, and airspeed progressively reduces, and pressure just increases, and reaches the purpose of pressurized gas.At present institute's employing Diffuser is non-adjustable, and adjustable vane and Diffuser all are the deficiencys of regulating separately.
Three. summary of the invention
The purpose of this utility model provides a kind of simple in structure, realize the import adjustable vane and the interlock of adjustable Diffuser of centrifugal refigerating compressor, make both more accurate couplings, unit operation efficient is higher, effectively solves unit surging phenomenon under the very little aperture of import adjustable vane.
The technological scheme that the purpose of this utility model adopted is, the output spindle mounted of motor has impeller, the a plurality of tapered inlet adjusting blade that eccentric wheel is arranged on the output shaft of the stepper motor that installs on the housing of its centrifugal refigerating compressor and in housing, adorn, cut open a tube wall by the output of the Diffuser exterior edge face of annular groove in being of impeller outlet end and centrifugal refigerating compressor distance is arranged, annular groove device has the guide rod of band spring in another of Diffuser, the other end of guide rod has screw thread and locking nut engagement, and the shaft axis of guide rod and eccentric wheel assembling are at grade.
The utility model adopts width-adjustable joint Diffuser, and promptly the Diffuser width of flow path changes with import adjustable vane angle, makes the tolerance that enters centrifugal refigerating compressor and changes.When big, the Diffuser width is big as import adjustable vane aperture; Import adjustable vane aperture hour, the Diffuser width is little, makes air-flow path mate mutually, and high pressure draught can not flow backwards, and not surge improves efficient.Stepper motor rotating band movable eccentric wheel and the rotation of import adjustable vane, eccentric wheel promotes guide rod simultaneously, and drives moving of Diffuser, makes the Diffuser width obtain adjusting.So under the stepper motor effect, make the interlock of import adjustable vane and adjustable Diffuser.
The utility model is simple and compact for structure, and fabrication and installation are convenient, and the unit efficiency height is energy-conservation, efficiently solves unit characteristics such as surging phenomenon under very little import adjustable vane aperture.
Four. description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is the utility model sectional structure schematic representation.
Among the figure: 1-stepper motor 2-eccentric wheel 3-spring 4-guide rod 5-Diffuser 6-impeller 7-import adjustable vane 8-main shaft 9-locking nut 10-housing
Five. embodiment
As shown in drawings, main shaft 8 is equipped with impeller 6, centrifugal refigerating compressor housing 10 devices have the output shaft of stepper motor 1 that eccentric wheel 2 and the inlet adjusting blade 7 in housing 10 are housed, and Diffuser 5 devices have the guide rod 4 of band spring 3, and the other end of guide rod 4 has screw thread and locking nut 9 engagements.
Claims (1)
1. the import adjustable vane of a centrifugal refigerating compressor and adjustable Diffuser linkage, the output main shaft (8) of motor is equipped with impeller (6), the housing (10) that it is characterized in that centrifugal refigerating compressor is gone up a plurality of tapered inlet adjusting blade (7) that eccentric wheel (2) is arranged and adorn on the output shaft of stepper motor (1) of device housing (10) in, Diffuser (5) outer end of annular groove and the output position tube wall of centrifugal refigerating compressor have distance in being by impeller (6) outlet end inner housing (10), annular groove device has the guide rod (4) of band spring (3) in another of Diffuser (5), the other end of guide rod (4) has screw thread and locking nut (9) engagement, and the shaft axis of guide rod (4) and eccentric wheel (2) assembling are at grade.
