(13) radially-outer surface middle position is mounted in the sleeve central bore of axle sleeve one (14), and keeps shaft one (13) axially external
One end passes through the side plate axis hole of side plate one (16), so that the axially external one end of shaft one (13) is located at side plate one (16) axially external；
It is mounted on shaft two (7) radially-outer surface middle position in the sleeve central bore of axle sleeve two (6), and makes shaft two (7) axis
One end passes through the side plate axis hole of side plate two (8) outward, so that the axially external one end of shaft two (7) is located at side plate two (8) axis outside
Side；Centrifugal flow guiding spiral case (2) is mounted on the upper end of wheel member, and a part of wheel member is made to be located at centrifugal flow guiding snail
Shell (2) inner cavity, make the sealing semi-ring two (34) of centrifugal flow guiding spiral case (2) respectively with the sealing semi-ring one (58) of base (1) and
The impeller ring (36) of impeller (3) is axially aligned；It seals semi-ring two (34) and sealing semi-ring one (58) is formed completely
Annulus, impeller ring (36) are located at sealing semi-ring two (34) and seal the radially inner side of semi-ring one (58), impeller ring
(36) there is radial clearance between radially-outer surface and sealing semi-ring two (34) and sealing semi-ring one (58) inner radial surface；From
The installing web plate two (32) of heart water conservancy diversion spiral case (2) is mounted on fixation gusset two (27) upper surface of base (1), centrifugal flow guiding snail
The installing web plate one (35) of shell (2) is mounted on fixation gusset one (30) upper surface of base (1)；Several bolts are each passed through
The bolt hole of the fixation gusset two (27) of the bolt hole (10) and base (1) of the installing web plate two (32) of centrifugal flow guiding spiral case (2)
(10), several bolts are each passed through the bolt hole (10) and base (1) of the installing web plate one (35) of centrifugal flow guiding spiral case (2)
Fixation gusset one (30) bolt hole (10), be fixed together centrifugal flow guiding spiral case (2) with base (1)；Electronic
The shaft of machine links together with shaft one (13), alternatively, the shaft of motor is linked together with shaft two (7).
2. the application method that a kind of through-flow according to claim 1 is centrifuged hybrid blower, it is characterised in that: the mixing
Formula fan operation process is:
When the hybrid fan operation, motor is by shaft one (13), impeller end plate one (17) driving impeller (3) along leaf
Direction of rotation (49) rotation is taken turns, alternatively, motor is by shaft two (7), impeller end plate two (4) driving impeller (3) along impeller
Direction of rotation (49) rotation, air-flow enter air inlet inner cavity (48) from air inlet (12), and the air-flow in air inlet inner cavity (48) is from impeller
The blade passage (39) of the close air inlet inner cavity (48) of through-flow section enters impeller inner cavity (55), into one of impeller inner cavity (55)
Air-flow is divided to enter through-flow spiral case inner cavity (46) from the blade passage (39) of the close through-flow spiral case inner cavity (46) of impeller through-flow section, this
Fraction is accelerated in the flow process through impeller through-flow section, and then this fraction is in through-flow spiral case inner cavity (46)
Slow down pressurization, the kinetic energy that impeller (3) passes to air-flow is changed into potential energy, generation high pressure draught, in through-flow spiral case inner cavity (46)
Air-flow along air outlet airflow direction (19) from air outlet (18) be discharged；Enter impeller inner cavity (55) from air inlet inner cavity (48)
Another part air-flow axially flows into turbine centrifugal section, and under the influence of centrifugal force, the air-flow is from turbine centrifugal section
Blade passage (39) enter anticentripetal spiral casing inner cavity (59), anticentripetal spiral casing inner cavity (59) sectional area is gradually increased, and air-flow is being centrifuged
Slow down in spiral case inner cavity (59) and be pressurized, the kinetic energy that impeller (3) passes to air-flow is changed into potential energy, generates high pressure draught, centrifugation
Air-flow in spiral case inner cavity (59) is discharged along air outlet airflow direction (19) from air outlet (18)；Anticentripetal spiral casing inner cavity (59) row
Stream pressure out is greater than the stream pressure of through-flow spiral case inner cavity (46) discharge, realizes and improves the hybrid blower overall output
Stream pressure.
