Abstract
The utility model discloses a round tube type energy transducer. The round tube type energy transducer comprises an outer metal sleeve and a piezoelectric ceramic tube, wherein an inner metal sleeve is arranged in the piezoelectric ceramic tube and is in interference connection with the piezoelectric ceramic tube; the thermal expansion coefficient of the inner metal sleeve is higher than that of the outer metal sleeve, and the acoustic resistance of the inner metal sleeve is higher than that of the outer metal sleeve; and because the inner metal sleeve is in interference connection with the piezoelectric ceramic tube, the thermal expansion coefficient of the inner metal sleeve is higher than that of the outer metal sleeve, and the acoustic resistance of the inner metal sleeve is higher than that of the outer metal sleeve, when the round tube type energy transducer works, the prestress on the piezoelectric ceramic tube is increased along with the rise of the temperature, and thus the power capacity and the reliability of the round tube type energy transducer can be greatly improved.
Description
Technical field
The utility model relates to a kind of circular pipe type transducer.
Background technology
The circular pipe type transducer is a kind of device that can realize that electric energy and mechanical energy are changed each other.Existing circular pipe type transducer mainly comprises outer metal sleeve and piezoelectric ceramic tube; Outer metal sleeve and piezoelectric ceramic circular tube have been formed a complex vibration structure, and its mode of oscillation is the central diameter direction pucker & bloat along pipe.Existing circular pipe type transducer is at running hours; In very short time, it can produce a large amount of heat, but the thermal coefficient of expansion of the thermal coefficient of expansion of outer metal sleeve and piezoelectric ceramic tube is inequality; Making the prestressing force that acts on piezoelectric ceramic circular tube to raise with temperature reduces; Because the tensile strength of piezoceramic material itself is lower, to answer in advance under the condition low, piezoelectric ceramic circular tube is very easily cracked; Thereby the power capacity and the reliability that cause the circular pipe type transducer to bear all can significantly reduce, and therefore existing circular pipe type transducer exists power capacity and the low defective of reliability.
The utility model content
For solving the problems of the technologies described above, the utility model provides the circular pipe type transducer that a kind of power capacity is big, reliability is high.
For achieving the above object, the technical scheme of the utility model is following:
A kind of circular pipe type transducer comprises outer metal sleeve and piezoelectric ceramic tube, is provided with interior metal sleeve in the piezoelectric ceramic tube; Interior metal sleeve is connected with the piezoelectric ceramic tube interference; The thermal coefficient of expansion of interior metal sleeve is higher than the thermal coefficient of expansion of outer metal sleeve, and the acoustic resistance of interior metal sleeve is higher than the acoustic resistance of outer metal sleeve.
Preferably, the material of interior metal sleeve is a brass.
Preferably, the material of outer metal sleeve is a titanium alloy.
Through technique scheme, a kind of circular pipe type transducer that the utility model provided is because interior metal sleeve is connected with the piezoelectric ceramic tube interference; The thermal coefficient of expansion of interior metal sleeve is higher than the thermal coefficient of expansion of outer metal sleeve, and the acoustic resistance of interior metal sleeve is higher than the acoustic resistance of outer metal sleeve, makes this circular pipe type transducer when work; Along with temperature raises; The prestressing force that piezoelectric ceramic tube receives can increase, thereby can improve the power capacity of this circular pipe type transducer greatly, and reliability.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the front view of the disclosed a kind of circular pipe type transducer of the utility model embodiment;
Fig. 2 is the vertical view of the disclosed a kind of circular pipe type transducer of the utility model embodiment.
The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
With reference to figure 1 and Fig. 2, the utility model provides a kind of circular pipe type transducer, and it comprises outer metal sleeve 1 and piezoelectric ceramic tube 2, metal sleeve 3 in being provided with in the piezoelectric ceramic tube 2; Interior metal sleeve 3 is connected with piezoelectric ceramic tube 2 interference; The material of interior metal sleeve 3 is a brass; The material of outer metal sleeve 1 is a titanium alloy; Because the thermal coefficient of expansion of brass is higher than the thermal coefficient of expansion of titanium alloy, and the acoustic resistance of brass is lower than the acoustic resistance of titanium alloy, promptly; The thermal coefficient of expansion of interior metal sleeve 3 is higher than the thermal coefficient of expansion of outer metal sleeve 1, and the acoustic resistance of interior metal sleeve 3 is lower than the acoustic resistance of outer metal sleeve 1.
It should be noted that present embodiment not internally the material of metal sleeve limit, its material can also be a stainless steel except being the brass.
Can find out through technique scheme; A kind of circular pipe type transducer that the utility model provided, because interior metal sleeve 3 is connected with piezoelectric ceramic tube 2 interference, the thermal coefficient of expansion of interior metal sleeve 3 is higher than the thermal coefficient of expansion of outer metal sleeve 1; And the acoustic resistance of interior metal sleeve 3 is higher than the acoustic resistance of outer metal sleeve 1; Make this circular pipe type transducer when work, along with temperature raises, the prestressing force that piezoelectric ceramic tube 2 receives can increase; Thereby can improve the power capacity of this circular pipe type transducer greatly, and reliability.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
