Abstract
A dual-flow vene wheel for pipeline is composed of centrifugal venes, front disk, axial-flow venes, back disk and axle sleeve welded to the center of back disk. It has a front centrifugal venes segment playing the role of centrifugal blower, a back axial-flow venes segment playing the role of axial-flow blower, and a middle segment between them.
Description
Technical field:
What the present invention relates to is a kind of Pipe double axial-flow impeller, and particularly a kind of impeller that is useful in conveying gas in the pipeline belongs to field of fluid machinery.
Background technique:
In prior art, in the pipeline delivery air use very generally pipeline centrifugal blower or pipeline axial flow (oblique flow) blower fan.The installation shaft flow fan is to the airflow influence minimum in pipeline, but because the blast that the pipe axis flow fan produces is too low, makes its application be subjected to very big restriction.When in pipeline centrifugal blower being installed dual mode is arranged, 1. the impeller center line is vertical with conduit axis; 2. the impeller center is concentric with conduit axis.Under first kind of situation, air-flow has 90 ° turns back at the impeller inlet place, lost a part of blast; Under second kind of situation, air-flow has 90 ° turns back at the impeller outlet place, makes the advantage of centrifugal blower finely not bring into play.When pipe resistance was big, the throughput of conveying did not satisfy requirement.The patent No. is 92228886.0, and name is called the patent of " two-sided blade impeller ", and it is " to have increased one group of blade newly on the paddle wheel plane near this end of shaft coupling hole.Former being trapped in is difficult for the liquid of draining and just produces centrifugal force and in time drained under the effect of newly-increased blade in the pump case." this mainly is a kind of impeller of carrying liquid, and the blade that increases is mainly at the shaft coupling nose end, thereby can not give ducted liquid adherence pressure.The patent No. is 01260051.2, name is called the patent of " impeller that is used for boosting centrifugal blower ", " side of impeller is a blade, and the opposite side of impeller is provided with auxiliary blade ", because auxiliary blade is in " space between casing group inwall ", thereby does not play adherence pressure.
Summary of the invention:
Deficiency and the defective of the present invention in order to overcome prior art increases the blast of air-flow when flowing through impeller, overcomes the bigger resistance of pipeline, satisfies the throughput that must carry in the pipeline.Therefore constructed a kind of simple in structurely, can overcome ventilating machinary---the Pipe double axial-flow impeller of big resistance during work.This impeller mainly is made up of shroud, hub disk, axle sleeve, centrifugal blade and axial blade etc.Shroud couples together by centrifugal blade and axial blade and hub disk, and axle sleeve then is welded on back disk center.Shroud and hub disk are all different with traditional form, because air-flow is turned back after leaving centrifugal blade, flow vertically, so shroud and hub disk have all increased to the axial part of turning back, extend to the impeller outlet place always.Centrifugal blade is preceding, axial blade after.Therefore the runner of impeller shroud and hub disk formation comprises three sections, and is in the centrifugal blade section, similar with centrifugal blower; In the axial blade section, the shroud of impeller and hub disk play a part the shell and the wheel hub of axial-flow blower respectively, have formed an annular pass; Part between centrifugal blade and the axial blade has formed intermediate section, and this section is changeable as required, in addition can be centrifugal by dwindling, the distance between the axial blade, intermediate section is disappeared.Because in Pipe double axial-flow impeller, centrifugal blade and axial blade increase energy to air-flow simultaneously, make air-flow have enough energy to overcome ducted flow losses.
The present invention is easy to use, has use value.
The drawings and the specific embodiments:
Fig. 1 is the Pipe double axial-flow impeller structure principle chart, and 1 is centrifugal blade, the 2nd among the figure, shroud, the 3rd, axial blade, the 4th, hub disk, the 5th, axle sleeve, the 6th, intake grill, the 7th, exhaust outlet.
Below in conjunction with accompanying drawing concrete enforcement of the present invention is further described:
As shown in Figure 1, Pipe double axial-flow impeller mainly comprises centrifugal blade 1, shroud 2, axial blade 3, hub disk 4 and axle sleeve 5.Shroud 2 couples together with hub disk 4 by centrifugal blade 1 and axial blade 3, and 5 on axle sleeve is welded on hub disk 4 centers.Shroud 2 and hub disk 4 are all different with traditional form, turn back because air-flow leaves centrifugal blade 1 back, flow vertically, so shroud 2 and hub disk 4 have all increased to the axial part of turning back, extend to impeller exhaust outlet 7 places always.Centrifugal blade 1 is preceding, axial blade 3 after.Therefore the runner of impeller shroud 2 and hub disk 4 formation comprises three sections, and is 1 section of centrifugal blade, similar with centrifugal blower; 3 sections of axial blades, the shroud 2 of impeller and hub disk 4 play a part the shell and the wheel hub of axial-flow blower respectively, have formed an annular pass; Part between centrifugal blade 1 and the axial blade 3 has formed intermediate section, and this section is changeable as required, even can intermediate section be disappeared by dwindling the distance between centrifugal blade 1 and the axial blade 3.
When Pipe double axial-flow impeller is worked under motor driving, air-flow sucks from intake grill 6, the centrifugal blade 1 of flowing through, radially throw away in the centrifugal action downstream, the axial blade 3 of flowing through after turning back, the pressure loss that the energy that air-flow is obtained through axial blade 3 is enough to overcome air-flow when turning back flows out impellers from exhaust outlet 7 at last.
