As further scheme of the invention, the full sawtooth of the step lining of the cone gear ring and positioning seat, the two of positioning tube
End is covered with sawtooth, and withstands on cone gear ring respectively and positioning seat is covered with the step of sawtooth.
As further scheme of the invention, the positioning tube, positioning seat, cone gear ring, left and right bearing inner race, left and right impeller
Synchronous high-speed rotation on the same axis.
Compared with prior art, the beneficial effects of the invention are as follows：
(1) the without hindrance air inducing pump of following current of the present invention is applied to industrial premises, vessel hotel, spray painting barn and big kitchenette etc. perhaps
The performance optimization of dedusting smoke evacuation, ventilation air discharging facility in many work living space, makes exhaust air rate improve as far as possible, installs cloth
Put, exhaust effect, the aspect such as noise control are improved.
(2) the without hindrance air inducing pump exhaust of following current of the present invention amplifies air inlet using the rotation of bilobed wheel synchronous high-speed again by smooth
End and the pressure difference of exhaust end, under conditions of power of motor consumption and ventilating opening sectional area are certain, its capacity can be higher than general
The centrifugal fan or axial fan for using.
(3) mounting arrangements of the without hindrance air inducing pump of following current of the present invention are more facilitated.According to capacity grade just, enter, arrange
Gas port diameter is mutually matched with the nominal diameter of conventional discharge duct, and the installation of air inducing pump lays one just as one section of discharge duct
Sample, only need to ensure firm position, it is not necessary to consider pump housing orientation.
(4) the without hindrance air inducing pump of following current of the present invention does not have any Bottle Neck Road from air inlet to exhaust outlet, forms blocking circuit phenomenon
Possibility very little, the part such as pump case and cone gear ring makes further through injection one-shot forming, is conducive to suppressing the generation of noise.
(5) the without hindrance air inducing pump configuration of following current of the present invention is compact to design, and parts assembly relation rationally, advantageously reduces production
Cost, has widely for enduring the Working Life space dust removal smoke evacuation perplexed of dust, smell, steam, oil smoke, air draft of taking a breath to the fullest extent
Applicability.
Brief description of the drawings
Fig. 1 is the structural representation of the without hindrance air inducing pump of following current of the present invention.
In figure：1st, pump case 2, positioning seat 3, positioning tube 4, cone gear ring 5, bearing 6, impeller 7, bevel gear 8, motor.
