什么是超聲波發生器？

發布時間：2021-11-23    字號：大  中  小
超(chao)聲(sheng)波(bo)發生器(qi)又稱為超(chao)聲(sheng)波(bo)電(dian)(dian)(dian)(dian)箱(xiang)、超(chao)聲(sheng)波(bo)電(dian)(dian)(dian)(dian)源(yuan)(yuan)。它的作(zuo)(zuo)用是把(ba)我們的市電(dian)(dian)(dian)(dian)(220V或380V，50或60Hz)轉換(huan)成與超(chao)聲(sheng)波(bo)換(huan)能器(qi)相匹(pi)(pi)配的高頻交流電(dian)(dian)(dian)(dian)信號。從(cong)放(fang)大(da)(da)電(dian)(dian)(dian)(dian)路形(xing)式，可(ke)以采用線(xian)性(xing)放(fang)大(da)(da)電(dian)(dian)(dian)(dian)路和(he)開關(guan)電(dian)(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)(dian)路，大(da)(da)功率超(chao)聲(sheng)波(bo)電(dian)(dian)(dian)(dian)源(yuan)(yuan)從(cong)轉換(huan)效(xiao)率方面考(kao)慮(lv)一般(ban)采用開關(guan)電(dian)(dian)(dian)(dian)源(yuan)(yuan)的電(dian)(dian)(dian)(dian)路形(xing)式。線(xian)性(xing)電(dian)(dian)(dian)(dian)源(yuan)(yuan)也有(you)它特有(you)的應用范圍，它的優點是可(ke)以不(bu)嚴格(ge)要(yao)求(qiu)電(dian)(dian)(dian)(dian)路匹(pi)(pi)配，允許工作(zuo)(zuo)頻率連續快(kuai)速變化。從(cong)目前(qian)超(chao)聲(sheng)業(ye)界的情況看，超(chao)聲(sheng)波(bo)主要(yao)分為自激式和(he)它激式電(dian)(dian)(dian)(dian)源(yuan)(yuan)。

超(chao)聲波發(fa)生(sheng)器的(de)原(yuan)理是首(shou)先由信(xin)號發(fa)生(sheng)器來產(chan)生(sheng)一(yi)個特定(ding)(ding)頻(pin)率(lv)的(de)信(xin)號，這(zhe)個信(xin)號可以(yi)(yi)(yi)是正弦信(xin)號，也可以(yi)(yi)(yi)是脈沖信(xin)號，這(zhe)個特定(ding)(ding)頻(pin)率(lv)就(jiu)是換能器的(de)頻(pin)率(lv)，一(yi)般應用(yong)在(zai)超(chao)聲波設備中的(de)超(chao)聲波頻(pin)率(lv)為(wei)20KHz、25KHz、28KHz、33KHz、40KHz、60KHz;100KHz或以(yi)(yi)(yi)上(shang)現在(zai)尚未(wei)大(da)量使(shi)用(yong)。但隨著以(yi)(yi)(yi)后(hou)精密清洗的(de)不斷發(fa)展。相信(xin)使(shi)用(yong)面會(hui)逐步擴大(da)。
