Description
Technical field
The utility model relates to convergent flaring jet pipe field, is specifically related to a kind of segmented changeable performance convergent increaser.
Background technique
Tradition convergent flaring jet pipe adopts welding or casting to form, and the physical dimension at each position of its inside is fixing, comprises the quantity and spout bore etc. of nozzle.Its power plant parameter be equipped with of this structural requirement is unique in theory, the excursion of actual motion medium power parameter also can only be very little, otherwise be that the waste of power plant energy consumption is large, it is vacuum degree deficiency, suction capactity declines greatly, even can not aspirate, cause finally or again purchasing new power plant, or new design convergent increaser; In addition on the one hand, even if power plant and convergent increaser can cooperatings well, meet the requirements of vacuum aspiration level, but raises due to the resistance of downstream fluid, and cause aspirating conveying capacity decline, even can not aspirate.
Therefore, develop a kind of novel convergent increaser, the changeable performance convergent increaser being applicable to the power plant of plurality of specifications and downstream pipe situation is very necessary.Because the kinetic parameter scope of adaptation is very wide, both avoided the waste of power plant or idle, and can adapt to downstream pipe complicated and changeable again, not needing very large convergent increaser for investment, is considerable.
Model utility content
For prior art Problems existing, provide a kind of segmented changeable performance convergent increaser.
The technical solution adopted in the utility model is:
A kind of segmented changeable performance convergent increaser, comprise suction casing and mixing section, mutually isolated suction chamber and power cavity is established in described suction casing, described suction casing is provided with motive fluid import, fluid intake and exhaust port, described fluid intake is communicated with described suction chamber, and described motive fluid import is communicated with described power cavity; In addition, also comprise injection dish, described injection dish is provided with through hole and nozzle, and described injection dish is removably connected to described exhaust port place; Establish cavity in described mixing section, the import of peripheral hardware and described cavity connects, the entrance point of described mixing section and the exhaust port end of described suction casing removably connect; Described power cavity is by described nozzle and described cavity connects, and described suction chamber is by described through hole and described cavity connects.
As preferred implementation of the present utility model, the cavity in described mixing section comprises three chambers, is from the close-by examples to those far off followed successively by convergent chamber, venturi chamber and flaring chamber by apart from described import.
As preferred implementation of the present utility model, described convergent chamber and flaring chamber are conical cavity, and the sharp end in described taper convergent chamber and taper flaring chamber is all towards described venturi chamber.
As preferred implementation of the present utility model, described venturi chamber is column chamber.
As preferred implementation of the present utility model, described nozzle is arranged relative to the axioversion of described through hole.
As preferred implementation of the present utility model, described through hole is positioned at described injection disk center, and multiple described nozzle is uniformly distributed around described through hole.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
1, the bull injection dish structure changed is easy to.The structure of injection dish is directly connected to the performance parameter of supporting power plant.Convergent increaser in many cases all with power plant joint work.The injection dish being easy to change can make convergent increaser according to the parameter of power plant to adjust the performance of convergent increaser, can avoid the idle or discarded of power plant like this, thus avoid larger investment loss completely;
2, removable mixing section structure can guarantee the adaptability of device to various back pressure.Under certain kinetic parameter, the suction of convergent increaser, performance is very large by the impact of back pressure.Back pressure is little compared with suction flow time high, and back pressure is large compared with suction flow time low.Because the downstream pipe situation of reality is complicated and changeable, and be designed with difference, and there is the reasons such as not easily replacing, therefore possessing the adaptive mixing section of good flow passage resistance force of waterproof is very economic and practical design; In addition, change behind place to use and also often need to consider that convergent increaser is to the applicability of pipeline, reconfigures one end of convergent increaser, very easy and economical;
3, owing to having good economic value to the broad applicability of power plant and downstream pipe back pressure simultaneously, make user that most economical method can be selected easily to combine new convergent increaser;
4, take up an area little, waterbornely all can to arrange under water, convenient, flexible; Stable and reliable operation, Maintenance free;
5, the replacing of parts is convenient, dismantles easy.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is described further.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
embodiment 1
Shown in composition graphs 1 and Fig. 2, a kind of segmented changeable performance convergent increaser, comprise suction casing 1 and mixing section 2, mutually isolated suction chamber 3 and power cavity 4 is established in described suction casing, described suction casing is provided with motive fluid import 5, fluid intake 6 and exhaust port 7, described fluid intake is communicated with described suction chamber, and described motive fluid import is communicated with described power cavity; In addition, also comprise injection dish 8, described injection dish is provided with through hole 9 and nozzle 10, and described injection dish is removably connected to described exhaust port place; Establish cavity in described mixing section, the import of peripheral hardware and described cavity connects, the entrance point of described mixing section and the exhaust port end of described suction casing removably connect; Described power cavity is by described nozzle and described cavity connects, and described suction chamber is by described through hole and described cavity connects.
Working principle of the present utility model is, there is the motive fluid of certain pressure, enter power cavity 4 from power fluid inlet 5, then penetrated, in critical flow velocity state by removable injection dish 8, convergent cavity pressure will lower than suction pressure, thus generation pumping action, external fluid enters suction chamber 3 by fluid inlet port 6, then via through holes 9 enters in the cavity of described mixing section 2, the motive fluid penetrated with injection dish mixes, and discharges finally by outlet 14.
Due to the detachable replacing of bull injection dish, the utility model goes for the dynamic medium of multiple pressure and flow, thus goes for the collocation of a series of power plant, greatly improves applicability; On the other hand, removably connecting of mixing section and suction casing, while making injection dish be convenient to take out, mixing section itself is also convenient to change, and therefore convergent increaser of the present utility model is applicable to the situation of various back pressure.When back pressure is very high, be variablely changed to little ability high back pressure type mixing section; And when back pressure is very low, replaceable is large discharge low back pressure type mixing section, meet various working condition flexibly.
