Description
Technical field
The present invention relates to a kind of engineering goods, particularly relate to a kind of blower fan.
Background technology
The blower fan of same performance parameter has multistage centrifugal blower and roots blower in the market, but efficiency is all not as high, is primarily present problems with:
One, multistage centrifugal blower leaks (volumetric loss) due to inter-stage, the leakage (volumetric loss) in impeller port ring gap, the aerodynamic force loss that blade design brings, and the operational efficiency of multistage centrifugal blower is 65% ~ 70%; Multistage centrifugal blower is because bringing at a high speed noise, and vibration is big, there is surge phenomenon simultaneously, reduces the service life of equipment.
Two, roots blower falls within positive displacement blower fan, owing to it is external compression, brings internal energy loss, air to breathe heavily conductance and causes high drops, the phenomenons such as deficiency in draught often occur. Roots blower fan blade machining accuracy is high, and final assembly difficulty is big, and gap adjusts bad, and easily stuck, gear should wear and tear, it is impossible to repairs, causes excesssive gap, and efficiency declines, and noise vibrates also relatively larger.
Summary of the invention
The technical problem to be solved is to provide a kind of blower fan, and it is positive displacement blower fan, and efficiency is high, and noise is low, operates steadily.
The present invention solves above-mentioned technical problem by following technical proposals: a kind of blower fan, it is characterized in that, it includes the first three-apexed rotor and the second three-apexed rotor, first three-apexed rotor, the second three-apexed rotor are symmetrical with compressing section in the axial direction, radial disbalance vector become 180 degree symmetrical, the inner side of the first three-apexed rotor, the second three-apexed rotor inner side be fitted with gear ring, the inner side of gear ring is provided with an eccentric shaft, equipped with gear on eccentric shaft, the gear ratio of gear ring and gear is 3:1.
Preferably, two balance weights it are provided with between described first three-apexed rotor and the second three-apexed rotor.
Preferably, between outside and a housing of described first three-apexed rotor, being respectively equipped with seal roll parts between outside and the housing of the second three-apexed rotor, seal roll parts are made up of roller, bracket, and roller floats on bracket.
Preferably, described compressing section is provided with two inlet holes and two discharge holes.
Preferably, the outside of described balance weight is provided with model plug envelope.
Preferably, described geared sleeve is on an axle, and the outside of axle is connected with a sliding bearing.
The actively progressive effect of the present invention is in that: blower fan of the present invention is positive displacement blower fan, and efficiency is high, and noise is low, operates steadily.
Accompanying drawing explanation
Fig. 1 is the structural representation of blower fan of the present invention.
Detailed description of the invention
Present pre-ferred embodiments is provided, to describe technical scheme in detail below in conjunction with accompanying drawing.
As shown in Figure 1, blower fan of the present invention includes the first three-apexed rotor 1 and the second three-apexed rotor 12, first three-apexed rotor, second three-apexed rotor is symmetrical with compressing section 2 in the axial direction, radial disbalance vector becomes 180 degree of symmetries, the inner side of the first three-apexed rotor, the inner side of the second three-apexed rotor is fitted with gear ring 3, the inner side of gear ring 3 is provided with an eccentric shaft 4, equipped with gear 5 on eccentric shaft, the gear ratio of gear ring and gear is 3:1, that is axle rotation is turned around, three-apexed rotor rotates 1/3 circle relative to eccentric shaft, purpose is to reduce rotary inertia, operate steadily, strengthen the volume of suction chamber or delivery chamber, improve its work efficiency. two balance weights 6 it are provided with between first three-apexed rotor and the second three-apexed rotor. between the outside of the first three-apexed rotor and a housing 8, being respectively equipped with seal roll parts between outside and the housing 8 of the second three-apexed rotor, seal roll parts are made up of roller 7, bracket 13, and roller 7 floats on bracket. the outside of balance weight is provided with model plug envelope 9. gear 5 is enclosed within an axle 11, and the outside of axle 11 is connected with a sliding bearing 10, and sliding bearing 10 conveniently positions.
Compressing section is provided with two inlet holes and two discharge holes, the positional symmetry distribution of two inlet holes, the positional symmetry distribution in two discharge holes.
The invention have the characteristics that: one, owing to three-apexed rotor is eccentric rotary, rotor is had very big amount of unbalance, rotor rotates the countershaft generation amount of deflection of meeting, bend during in order to prevent axle from rotating, the present invention separately designs a three-apexed rotor in compressing section both sides, and make two three-apexed rotors rotate amount of unbalance radial symmetric, that is two three-apexed rotor amount of unbalance radial vectors become 180 degree, avoid the bending shaft that three-apexed rotor eccentric rotary causes, bending shaft can produce noise, vibration greatly, and frictional force is big, blocks situation of waiting indefinitely. Due to two three-apexed rotor blade arrangement axial distances farther out, even if so distributing installation three-apexed rotor, likely can not thoroughly eliminate the amount of unbalance on axle, for this situation, the present invention is provided with two balance weights (or being called " balancing weight ") between two three-apexed rotors, and the two balance weight becomes 180 degree with the unbalance vector of the three-apexed rotor of respective side respectively. Through calculating: the amount of unbalance on axle substantially eliminates, steadily reliable during three-apexed rotor blower fan actual motion, friction. Two, three-apexed rotor triangle place keeps gapless state with housing inner ring, in order to reduce frictional force, the present invention devises seal roll parts, is made up of roller, bracket, and roller floats on bracket, roller is relative with inner walls gapless to be rolled, being so designed that, not only friction loss is little, and volumetric efficiency loss is less. Three, machine envelope rotating ring adopts model plug envelope, and machine envelope stationary ring adopts nodular cast iron, using the teaching of the invention it is possible to provide very big compression ratio, it is adaptable to compressed air sealing, adopts film lubrication, reduces frictional force, improve fan efficiency between dynamic and static ring. Four, three-apexed rotor Its Track Design, calculate delivery chamber, suction chamber volume according to air quantity, blast, rotating speed, calculate the movement locus of three-apexed rotor further according to the size of this volume. Five, each three-apexed rotor side, equipped with gear ring, the eccentric shaft being matched therewith fills a gear, and gear ring and gear ratio are 3:1, say, that axle rotation is turned around, and three-apexed rotor rotates 1/3 circle relative to eccentric shaft. Gear driven gear ring rotates together when the shaft is rotated, and three-apexed rotor does eccentric rotary under the drive of gear ring, and gear turns three circles just can cover gear ring one circle, therefore, axle turns three circles, and three-apexed rotor turns around, and three-apexed rotor blade completes twice air-breathing and aerofluxus inside housing.
Particular embodiments described above; the solving the technical problem that of the present invention, technical scheme and beneficial effect have been further described; it is it should be understood that; the foregoing is only specific embodiments of the invention; it is not limited to the present invention; all within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
