Abstract
The utility model discloses an online adjustable-type ejector, comprising an ejector shell, wherein a working steam inlet and an injection steam inlet which are communicated with the inner cavity of the ejector shell are arranged on the ejector shell respectively, the injection steam inlet is communicated with a suction chamber, the working steam inlet is communicated with the suction chamber via a nozzle, a mixing chamber and a diffusing chamber are further arranged at the head end of the ejector shell in sequence, and the outlet of the diffusing chamber is communicated with cooling equipment. The online adjustable-type ejector is characterized in that a stepper motor is arranged at the tail end of the ejector shell, the working end of the stepper motor is connected with a transfer speed change mechanism, the transfer speed change mechanism is provided with two output screws, and the two output screws are in threaded connection with a connection plate which is arranged at the tail end of the nozzle respectively. The online adjustable-type ejector is simple in structure, ingenious in design, and capable of adjusting the position of the nozzle at any time according to an actual working condition so as to ensure ejection efficiency.
Description
Technical field
The utility model relates to a kind of injector, particularly a kind of online adjustable spraying apparatus.
Background technology
Injector is a kind of widely used fluid machinery; It utilizes the jet of working fluid to realize that energy transforms; And with obvious energy-saving effect, oligosaprobic service behaviour, and advantage such as simple in structure, cheap, Operation and maintenance are convenient, in industrial circle, obtain general application.Traditional injector adopts the fixed nozzle structure, and this fixed structure only just can reach optimum condition under design condition, in case running parameter off-design value can cause ejector efficiency obviously to descend.Therefore need a kind of novel injection device that can address the above problem now.
Summary of the invention
The utility model is in order to solve the above-mentioned deficiency of existing in prior technology, proposes a kind of simple in structurely, designs ingeniously, can adjust nozzle location at any time to guarantee the online adjustable spraying apparatus of ejection efficiency according to the real work situation.
The technical solution of the utility model is: a kind of online adjustable spraying apparatus; Comprise case of sprayer 1; On case of sprayer 1, be respectively arranged with the working steam inlet 2 and jetting steam caused inlet 3 that communicate with its inner chamber, jetting steam caused inlet 3 is communicated with suction chamber 4, and 2 of working steam inlets pass through nozzle 5 and are communicated with suction chamber 4; Head end at case of sprayer 1 also is disposed with mixing chamber 7 and diffuser casing 8; The outlet of diffuser casing 8 is connected with cooling device, it is characterized in that: the end of said case of sprayer 1 is provided with stepper motor 9, and the working end of stepper motor 9 links to each other with transfer gear 10; Transfer gear 10 has two output screws 11, and these two output screws 11 are threaded with the connecting plates 12 that are arranged on nozzle 5 ends respectively.
The utility model is compared with prior art, has following advantage:
The online adjustable spraying apparatus of this kind of version; It is simple in structure; Design ingeniously, the existing problem of the injector of traditional structure form is: nozzle is fixedly installed in the injector, and the relative position between the two can't be adjusted according to actual needs; When causing this kind injector under the situation of non-standard running parameter, to be worked, efficient obviously descends.To this problem, design a kind of nozzle axially movable special construction in the inner certain limit of case of sprayer that can let now, to be adapted to the environment of different operating parameter, guarantee that this injector still can guarantee higher operating efficiency under multiple condition.And the low preparation cost of this injector, manufacturing process is simple, therefore we can say that it has possessed multiple advantage, is particularly suitable for applying in the art, and its market prospects are very wide.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below with the specific embodiment of accompanying drawings the utility model.As shown in Figure 1: a kind of online adjustable spraying apparatus; Comprise case of sprayer 1 as the basis; On case of sprayer 1, be respectively arranged with and the working steam of its intracavity inter-connection inlet 2 and jetting steam caused inlet 3, wherein jetting steam caused inlet 3 is connected with suction chamber 4, and working steam inlet 2 then is connected with suction chamber 4 through the nozzle 5 of setting vertically; The outlet that is nozzle 5 is arranged in the suction chamber 4; Head at case of sprayer 1 also is disposed with mixing chamber 7 and diffuser casing 8, and wherein the outlet of diffuser casing 8 is connected with cooling device, and mixed vapour is through among the entering cooling device after the outlet of diffuser casing 8;
Under the original state, the position of nozzle 5 in case of sprayer 1 housing meets the designing requirement of optimum condition, and the injector of work under the standard operation parameter state need not adjusted the particular location of nozzle 5, can obtain higher operating efficiency; But in real work; Each item running parameter tends to have certain deviation with the ideal parameters of envisioning; Injector work under the running parameter environment of non-design load often; Be difficult to reach optimum condition, only need promptly can address this problem through the particular location of adjustment nozzle 5 in case of sprayer 1 this moment.
9 work of control step motor; Two output screws 11 that the working end of stepper motor 9 drives transfer gear 10 rotate; And the connecting plate 12 that is threaded with output screw 11 is integrative-structures with nozzle 5; Therefore nozzle 5 just can through the direction of rotation of control step motor 9 working ends, can be controlled the direction of motion of nozzle 5 along the axially-movable of case of sprayer 1 under the effect of output screw 11.
This injector can realize adjusting as required at any time the relative position of nozzle 5, to be adapted to various different operating parameters, prevents the decline of operating efficiency.
