Abstract
Spheroidal suction chamber and the jet pump sucking straight pipe type, formed primarily of parts such as nozzle, suction chamber, mixing chamber, explosion chambers.In suction chamber, suction chamber is spheroidal, and its centre of sphere is on the axis of the pump housing; Suction pipe is straight tube, and its axis and pump housing axes normal, intake flange end face is vertical with working hole end face of flange.The utility model corresponding size is little, lightweight, and the suction chamber of more former same size pump, nozzle length and weight, can reduce 1/1 to two/3rd, save material, easy processing, efficiency is higher, easy for installation, there is important improvement than existing jet pump, be widely used.
Description
Technical field
The utility model relates to a kind of jet pump of fluid machinery, and especially in suction chamber, suction chamber is spheroidal and suction pipe is the jet pump of straight tube.
Jet pump be a kind of utilize jet turbulent diffusion to come transferring energy and quality fluid machinery and mix reaction equipment, be widely used in the fields such as boats and ships, water power, petrochemical industry, traffic, environmental protection, metallurgy, ocean, nuclear energy, Aero-Space.
Background technique
Jet pump is primarily of parts compositions such as nozzle, suction chamber, mixing chamber, explosion chambers.Suction chamber comprises suction port, suction pipe, working hole, suction chamber etc.The structural type of existing jet pump mainly contains two large types: first type is that suction pipe axis is consistent with pump housing axis, working hole axis and pump housing axes normal; Second largest type is that suction pipe axis and pump housing axis are inclined to several angle, and working hole axis is consistent with pump housing axis.First type is due to working hole axis and pump housing axes normal, and it is easy for installation; But main jet is syphon shape, manufacture processing difficulties, precision is difficult to ensure, larger on efficiency impact.Second largest types of nozzles is right cone pipe, and machining accuracy easily ensures; Be inhaled into fluid to flow out along the suction pipe axial direction tilted, avoid and working fluid vertical impact, therefore efficiency comparison be high.Wherein divide again two kinds: the first tilts for intake flange end face and pump housing axis, therefore inconvenience is installed; The second is intake flange end face and pump housing axis being parallel, vertical with working hole end face of flange, makes pump easy for installation, as jet pump with intaking bent pipe (ZL 98225832.1).The equal complicated structure of suction chamber of these two kinds of pumps, suction chamber is taper, and the suction pipe of inclination is long, and make the volume of suction chamber, weight comparatively large, processing is inconvenient, and precision is difficult to ensure card; Make the length of nozzle increase simultaneously, add the area of contact sucking fluid and nozzle, add coefficient of partial resistance, have certain influence to pump efficiency.
Model utility content
The purpose of this utility model is to overcome the deficiency in existing second largest type jet pump technology, provides a kind of relative size is short, volume is little, lightweight, easy processing, efficiency are higher, easy for installation spheroidal suction chamber and suction straight pipe type jet pump.
The utility model solves the technological scheme that its technical problem adopts: spheroidal suction chamber with suck straight pipe type jet pump and formed by nozzle, suction chamber, mixing chamber, explosion chamber and Sealing and fastener combination, suction chamber comprises suction chamber, suction pipe, intake flange, working hole flange.Improvements are suction chambers is spheroidal, and its centre of sphere is on the axis of the pump housing; Suction pipe is straight tube, and its axis and pump housing axes normal, intake flange end face is vertical with working hole end face of flange.
In above scheme, because spheroidal is the figure that in same volume, physical dimension is minimum, thus satisfied suction fluid participate in suction chamber working fluid contact mixing condition under, the physical dimension of suction chamber can have larger reducing; Simultaneously because suction pipe changes straight tube into, the length of the former suction elbow of shortening that can be larger, reduces boundary dimension and the overall volume of suction chamber further.
The beneficial effects of the utility model are: the suction chamber length of more existing same size pump (as jet pump with intaking bent pipe) and weight, can reduce 1/1 to two/3rd; Nozzle is corresponding shortening more than 1/3rd also, decreases nozzle and sucks the area of contact of fluid, reducing coefficient of partial resistance, improve to pump efficiency, counteracts part and sucks the efficiency that fluid and working fluid vertical impact reduce; Because corresponding size is little, lightweight, both saved material, easy to process again, save machining period, machining accuracy easily ensures simultaneously, also improves to pump efficiency; In addition, intake flange end face is vertical with working hole end face of flange, makes pump easy for installation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
As figure, spheroidal suction chamber is formed primarily of parts such as nozzle 2, suction chamber 3, mixing chamber 7, explosion chambers 8 with suction straight pipe type jet pump.Nozzle 2 is positioned at suction chamber 3, and its axis is consistent with pump housing axis 9.In suction chamber 3, suction chamber 4 is spheroidal, and its centre of sphere is on the axis 9 of the pump housing, and suction pipe 5 is straight tube, and its axis is vertical with pump housing axis 9, and intake flange 6 end face is vertical with working hole flange 1 end face.
Embodiment
Further illustrate the utility model below in conjunction with Fig. 1 and embodiment, the utility model is achieved in that nozzle 2 is positioned at suction chamber 3, and its axis is consistent with pump housing axis 9; In suction chamber 3, suction chamber 4 is spheroidal, and its centre of sphere is on the axis 9 of the pump housing, and suction pipe 5 is straight tube, and its axis is vertical with pump housing axis 9, and intake flange 6 end face is vertical with working hole flange 1 end face; Suction chamber 3 right-hand member and mixing chamber 7, explosion chamber 8 and Sealing and fastener combination are assembled.
