Abstract

The present invention relates to a kind of single-ended trapezoidal thread from the micro-nano air bubble apparatus of formula heliconid, belong to general field of engineering technology.Present Domestic forms the outward rotor of " Mazy spiral body structure " and the thread tooth type of stator surface is all a kind of thread tooth type.Although research proves that the composite tooth-shape screw thread be made up of two kinds of flute profile screw threads can be had complementary advantages, this cavity remains " Mazy spiral body " structure.This structure difficulty of processing is large.The present invention is all trapezoidal thread structure by the rotor surface of composition one of " Mazy spiral body ", and separate according to operating condition design and be made up of two or more part, this structure is called " from formula heliconid ".Generally 1: 1,1: 2 etc. from the spirochetal ratio that separates of formula.The processing of this structure is simple, and guarantees the stability that device operates.

Description

Single-ended trapezoidal thread is from the micro-nano air bubble apparatus of formula heliconid

Technical field the present invention relates to a kind of single-ended trapezoidal thread from the micro-nano air bubble apparatus of formula heliconid, belongs to general field of engineering technology.

The single end composite tooth type labyrinth screw pump patent No. of the current domestic design of background technique is: 200420007044.9 its structures as shown in Figure 1.Transported medium, under motor 1 rotates, is flowed in working cavity that the pump rotor 4 that is arranged on above pump bearing bracket 3 and pump stator 5 form (this cavity is called " Mazy spiral body ") by pump inlet flange 2, is got rid of by pump discharge flange 6.

Present Domestic forms the outward rotor of " Mazy spiral body structure " and the thread tooth type of stator surface is all a kind of thread tooth type.This patent No. is: 200420007044.9 single end composite tooth type labyrinth screw pumps, for improving pump duty and stability, by former " Mazy spiral body " rotor surface thread tooth type by a kind of thread tooth type, design and are made up of two kinds of flute profile compounds.Although research proves that the composite tooth-shape screw thread be made up of two kinds of flute profile screw threads has superiority, this cavity remains " Mazy spiral body " structure, and this structure difficulty of processing is large.By the discussion of many-side to current " Mazy spiral body structure ", think that this structure has narrow limitation, so the rotor of research and design device and the structure of stator are crucial.

Summary of the invention the object of the invention is a kind of single-ended trapezoidal thread of design from the micro-nano air bubble apparatus of formula heliconid.Be the pump rotor 4 that composite tooth-shape screw thread forms by existing Fig. 1 by integral surface, redesign as integral surface is the structure of trapezoidal thread, then according to working condition requirement, design separates and consists of the rotor 4 of single-ended trapezoidal thread from the micro-nano air bubble apparatus Fig. 2 of formula heliconid by two or more part.Now the rotor 4 of Fig. 2 can obtain buffering adjustment at the place of separating when fed sheet of a media, it is hereby ensured the stability that device operates.The processing of this project organization is simple.

The present invention, by the structure of traditional " Mazy spiral body " rotor integral surface with a kind of thread tooth type, separates according to operating condition design and is made up of two or more part.So new design changes the structural type of original " Mazy spiral body " rotor, and this structure is called " from formula heliconid ".The proportionate relationship that separates from formula heliconid rotor is generally 1: 1 or 1: 2 etc.

Description of drawings 1 is the structural representation of prior art, and Fig. 2 is structural representation of the present invention.

Embodiment introduces single-ended trapezoidal thread from the micro-nano air bubble apparatus of formula heliconid below in conjunction with Fig. 1 and Fig. 2 accompanying drawing: motor 1, suction flange 2, bearing support 3, rotor 4, stator 5, outlet(discharge) flange 6.

Specifically introduce content of the present invention.Be the pump rotor 4 that composite tooth-shape screw thread forms by existing Fig. 1 by integral surface, redesign as integral surface is a kind of worm structure of trapezoidal flute profile, then according to duty parameter, design separates the rotor 4 being consisted of Fig. 2 by two or more part.Medium can obtain buffering adjustment at the place of separating when rotor 4 is carried, and guarantee the stability that device operates.To be single-ended trapezoidal threads be all trapezoidal thread flute profile from the rotor of the micro-nano air bubble apparatus of formula heliconid and stator flute profile to one embodiment of the present of invention, and it is 1: 2 that rotor threads separates ratio, and rotor and stator diameter are all 80mm composition.
