Abstract
The invention relates to a separate-type treponemata micro-nanobubble device with a saw-tooth thread at a single end, and belongs to the technical field of universal engineering. The saw-tooth threads on the surfaces of domestic and foreign rotors and stators of 'labyrinth treponemata structures' in the current market are the same. Researches show that though thread bodies having two tooth types of a composite tooth-type thread can complement each other's advantages, cavities defined by the rotors and the stators are still of 'labyrinth treponemata' structures of which the machining difficulty is high. The invention has the advantage that instead of an all saw-tooth thread structure, the thread on the surface of a rotor of a 'labyrinth treponemata' can be designed into two or more separate parts according to working conditions, and the structure of the labyrinth treponemata is called as a 'separate-type treponemata' structure. The separate rate of the separate-type treponemata is usually 1:1, 1:2 and the like. The structure machining is simple, and the running stability of the device can be ensured.
Description
Technical field the present invention relates to a kind of single-ended buttress thread form 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 buttress thread form 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 buttress thread form, then according to working condition requirement, design separates and consists of the rotor 4 of single-ended buttress thread form 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 buttress thread form 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 zigzag fashion 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 buttress thread forms be all buttress thread form 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.
Claims (1)
1. a single-ended buttress thread form is from the micro-nano air bubble apparatus of formula heliconid, comprise device motor, bearing support, rotor, stator, suction flange and outlet(discharge) flange, it is characterized in that device rotor surface it being all buttress thread form structure, separate as two or more part forms according to operating condition design.
