超(chao)聲(sheng)波(bo)發生(sheng)器(qi)(qi)是(shi)(shi)應(ying)用聲(sheng)學原理將電(dian)(dian)(dian)(dian)能(neng)轉化為機(ji)械能(neng)的(de)(de)設備(bei)，它(ta)包括換(huan)能(neng)器(qi)(qi)、激勵(li)器(qi)(qi)、信(xin)號發生(sheng)和(he)換(huan)能(neng)器(qi)(qi)控制電(dian)(dian)(dian)(dian)路等(deng)部分。1.超(chao)聲(sheng)波(bo)發生(sheng)器(qi)(qi)的(de)(de)工作原理：當輸入(ru)的(de)(de)交流(liu)電(dian)(dian)(dian)(dian)壓(ya)達到(dao)(dao)一定(ding)值時，電(dian)(dian)(dian)(dian)感L1產生(sheng)自感電(dian)(dian)(dian)(dian)動勢，其大小正比于(yu)(yu)外(wai)(wai)加(jia)直流(liu)電(dian)(dian)(dian)(dian)壓(ya)，與(yu)(yu)外(wai)(wai)加(jia)直流(liu)電(dian)(dian)(dian)(dian)壓(ya)成(cheng)正比，即(ji)U=U0/I，此(ci)時電(dian)(dian)(dian)(dian)容器(qi)(qi)C2充(chong)電(dian)(dian)(dian)(dian)，由于(yu)(yu)C2內阻(zu)較大，故充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)不(bu)大，而(er)輸出端則因受到(dao)(dao)交變電(dian)(dian)(dian)(dian)壓(ya)的(de)(de)作用，使(shi)容抗減小，因而(er)對外(wai)(wai)界呈(cheng)現了(le)很大的(de)(de)阻(zu)力作用，阻(zu)礙了(le)外(wai)(wai)界高(gao)頻能(neng)量的(de)(de)進(jin)入(ru)，從而(er)使(shi)負(fu)載得到(dao)(dao)能(neng)量補充(chong)。當電(dian)(dian)(dian)(dian)源(yuan)停止后，由于(yu)(yu)電(dian)(dian)(dian)(dian)感L1、電(dian)(dian)(dian)(dian)容C2及(ji)電(dian)(dian)(dian)(dian)阻(zu)R上的(de)(de)壓(ya)降(jiang)，使(shi)得輸出端的(de)(de)電(dian)(dian)(dian)(dian)壓(ya)逐漸(jian)下(xia)降(jiang)到(dao)(dao)零伏(fu)，同時，由于(yu)(yu)在(zai)輸入(ru)端加(jia)有直流(liu)電(dian)(dian)(dian)(dian)壓(ya)U0，致使(shi)外(wai)(wai)電(dian)(dian)(dian)(dian)路中的(de)(de)高(gao)頻功率(lv)通過R上的(de)(de)壓(ya)降(jiang)傳遞給(gei)L1和(he)C2，從而(er)形成(cheng)回路。因此(ci)，在(zai)回路中有電(dian)(dian)(dian)(dian)流(liu)流(liu)過，并且，該電(dian)(dian)(dian)(dian)流(liu)與(yu)(yu)外(wai)(wai)加(jia)直流(liu)電(dian)(dian)(dian)(dian)壓(ya)的(de)(de)頻率(lv)相(xiang)同。山(shan)西耐用超(chao)聲(sheng)波(bo)發生(sheng)器(qi)(qi)按需定(ding)制超(chao)聲(sheng)波(bo)發生(sheng)器(qi)(qi)是(shi)(shi)超(chao)聲(sheng)波(bo)清洗機(ji)的(de)(de)重要組(zu)成(cheng)部分，他的(de)(de)質量與(yu)(yu)匹配(pei)程度直接決定(ding)了(le)清洗機(ji)的(de)(de)清洗效(xiao)果。
