Abstract
The invention discloses a tapered axial flow centrifugal compressor. The tapered axial flow centrifugal compressor comprises a centrifugal impeller. The centrifugal impeller comprises a tapered rotor. Centrifugal blades, axial flow blades and axial flow single blades are fixedly connected with the tapered rotor. The centrifugal blades and the axial flow blades are connected. The axial flow single blades are evenly distributed among the axial flow blades and located in the same radial plane. The angle of blade channels of the impeller is greater than 90 degrees. According to the tapered axial flow centrifugal compressor, air can be directly supplied to mechanical systems with axial air supplying demands, after the angle of the blade channels are adjusted to be greater than 90 degrees, airflow is forced to flow in an expected direction in the channels with the angle being greater than 90 degrees and is smoothly transited to axial direction for exhausting. The adjustment is specific to the systems with the axial air supplying demands and capable of reducing system resistance, and the air supplying efficiency is high.
Description
Technical field
The present invention relates to gas compressor technical field, particularly, relate to a kind of diminished shaft to stream centrifugal compressor.
Background technique
The working principle of centrifugal impeller is: during rotation, the gas of Ye Daonei outwards moves under the influence of centrifugal force, degree of vacuum is produced at impeller central position, thus axially suck air from intake grill, at impeller eye, place enters Ye Dao, and obtains kinetic energy and pressure energy under blade effect.
But common centrifugal compressor is that axial admission radial direction is given vent to anger.Gas band between centrifuge High Rotation Speed Shi Jiangye road turns, and under the influence of centrifugal force, is thrown away by gas by radial direction, forms degree of vacuum suction gas at the position, the center of circle of centrifuge simultaneously.As being used in the system of axial air feed demand, need to arrange 90 degree of bendings or the bending of " U " type water conservancy diversion after its radial exhaust by flow direction variation to axial exhaust, air-flow is forced to turn to axial flow, system resistance rises larger, energy, pressure relatively all can have certain loss, and air feed efficiency reduces more.
Summary of the invention
The object of the invention is to, for the problems referred to above, propose a kind of diminished shaft to stream centrifugal compressor.
Technological scheme of the present invention is: a kind of diminished shaft is to stream centrifugal compressor, comprise centrifugal impeller, described centrifugal impeller comprises cone rotor, described cone rotor is fixedly connected with centrifugal blade, axial blade and axial-flow single-blade, and described centrifugal blade is connected with axial blade; Described axial-flow single-blade is evenly distributed between described axial blade, and on the same plane of radial direction, the angle in described impeller Shang Ye road is greater than 90 degree.
Preferably, described centrifugal blade adopts hypsokinesis form.
Preferably, described centrifugal impeller exhaust side end is provided with axial-flow blower, and described axial-flow blower adopts the form that leans forward.
Beneficial effect of the present invention: diminished shaft of the present invention is to stream centrifugal compressor, direct air feed can be carried out to the mechanical system of axial air feed demand, after leaf road being done the adjustment of >90 degree, air-flow is forced to directional flow in the passage of >90 degree, mild excessively to axial exhaust.Such adjustment can reduce system resistance for there being the system of axial air feed demand, and air feed efficiency is high.
The axial flow compressor used relative to tradition or blower fan, adopt diminished shaft can provide higher pressure to stream centrifugal compressor or blower fan, gas transmission is stablized, and air input efficiency is higher, and system is relatively energy-conservation.When making blower fan and using, exhaust side can arrange static pressure chamber, can improve gas transmission static pressure, and blower fan range is larger.
Accompanying drawing explanation
Fig. 1 is the structural representation of diminished shaft of the present invention to a kind of embodiment of stream centrifugal compressor;
Fig. 2 is the blade wheel structure schematic diagram of diminished shaft of the present invention to stream centrifugal compressor;
In figure: 1 axle, 2 cone rotors, 3 centrifugal blades, 4 shells, 5 axial blades, 6 leaf roads, 7 axial-flow single-blades.
Embodiment
By reference to the accompanying drawings mode of execution provided by the invention is described in further detail:
A kind of diminished shaft is to stream centrifugal compressor, and comprise centrifugal impeller, described centrifugal impeller comprises cone rotor, described cone rotor is fixedly connected with centrifugal blade, axial blade and axial-flow single-blade, and described centrifugal blade is connected with axial blade; Described axial-flow single-blade is evenly distributed between described axial blade, and on the same plane of radial direction, the angle in described impeller Shang Ye road is greater than 90 degree.
As shown in Figure 1, diminished shaft comprises shell 4 and centrifugal impeller to stream centrifugal compressor, centrifugal impeller comprises cone rotor 2, described cone rotor 2 is fixedly connected with centrifugal blade 3, axial blade 5 and axial-flow single-blade 7, cone rotor 2 is pedestal, the run-in synchronism under the rotation of axle 1 of cone rotor 2, centrifugal blade 3, axial blade 5 and axial-flow single-blade 7, centrifugal blade 3, axial blade 5 are connected at centrifugal impeller exhaust side end, are linking body structures; Axial-flow single-blade is evenly distributed between axial blade, and on the same plane of radial direction, jointly forms axial-flow blower with axial blade.
Described centrifugal impeller exhaust side end is provided with axial-flow blower, and described axial-flow blower adopts the form that leans forward." centrifugal blade adopts hypsokinesis form " can improve distribution pressure, improves the operation stability of impeller; Axial-flow blower and " axial-flow blower adopts the form that leans forward " are set after centrifugal impeller exhaust, displacement can be increased to a certain extent, reduce the generation of surge.
As shown in Figure 1, 2, in the present invention during impeller rotating operation, form negative inspiratory pressure at impeller shaft to intakeport a place, under hypsokinesis impeller action, air-flow prolongs the flowing transmission of impeller Jian Ye road, and obtains kinetic energy and pressure energy under blade effect.When air stream transportation is to end, larger kinetic energy is obtained again under the effect of axial blade and axial-flow single-blade, and prolong the discharge of axial exhaust port b place, leaf road 6 angle is greater than 90 degree of settings, taper radial flow centrifuge in the running air-flow is still the trend of radial exhaust, after just air-flow path being done the adjustment of >90 degree, air-flow is forced to directional flow in the passage of >90 degree, mild excessively to axial exhaust.Such adjustment can reduce system resistance for there being the system of axial air feed demand.
In this description, the present invention is described with reference to its specific embodiment.But, still can make various amendment and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
