一(yi)(yi)(yi)、功(gong)(gong)率(lv)(lv)(lv)的(de)(de)選(xuan)擇(ze) 超(chao)聲(sheng)波清(qing)(qing)洗(xi)(xi)(xi)(xi)效(xiao)果(guo)(guo)(guo)不(bu)一(yi)(yi)(yi)定(ding)(ding)與(功(gong)(gong)率(lv)(lv)(lv)×清(qing)(qing)洗(xi)(xi)(xi)(xi)時(shi)(shi)間)成正比,有(you)(you)(you)(you)時(shi)(shi)用(yong)(yong)小(xiao)功(gong)(gong)率(lv)(lv)(lv),花費很長時(shi)(shi)間也(ye)沒有(you)(you)(you)(you)清(qing)(qing)除污垢。而如果(guo)(guo)(guo)功(gong)(gong)率(lv)(lv)(lv)達到(dao)一(yi)(yi)(yi)定(ding)(ding)數值,有(you)(you)(you)(you)時(shi)(shi)很快便將污垢去(qu)除。若選(xuan)擇(ze)功(gong)(gong)率(lv)(lv)(lv)太(tai)大,空化強(qiang)度(du)將大大增加,清(qing)(qing)洗(xi)(xi)(xi)(xi)效(xiao)果(guo)(guo)(guo)是提高了,但這(zhe)時(shi)(shi)使(shi)(shi)(shi)較精密的(de)(de)零件(jian)也(ye)產(chan)(chan)生蝕(shi)點,得不(bu)償失,而且清(qing)(qing)洗(xi)(xi)(xi)(xi)缸(gang)底(di)部振動板處空化嚴(yan)重,水(shui)(shui)點腐(fu)蝕(shi)也(ye)增大,在(zai)采(cai)用(yong)(yong)三氯乙(yi)烯等有(you)(you)(you)(you)機溶劑時(shi)(shi),基本上沒有(you)(you)(you)(you)問(wen)題,但采(cai)用(yong)(yong)水(shui)(shui)或水(shui)(shui)溶性清(qing)(qing)洗(xi)(xi)(xi)(xi)液時(shi)(shi),易于(yu)(yu)受(shou)到(dao)水(shui)(shui)點腐(fu)蝕(shi),如果(guo)(guo)(guo)振動板表面已受(shou)到(dao)傷痕(hen),強(qiang)功(gong)(gong)率(lv)(lv)(lv)下(xia)水(shui)(shui)底(di)產(chan)(chan)生空化腐(fu)蝕(shi)更(geng)嚴(yan)重,因此要(yao)按(an)實際使(shi)(shi)(shi)用(yong)(yong)情況選(xuan)擇(ze)超(chao)聲(sheng)功(gong)(gong)率(lv)(lv)(lv)。 二、頻(pin)(pin)(pin)率(lv)(lv)(lv)的(de)(de)選(xuan)擇(ze) 超(chao)聲(sheng)清(qing)(qing)洗(xi)(xi)(xi)(xi)頻(pin)(pin)(pin)率(lv)(lv)(lv)從28kHz到(dao)120kHz之間,在(zai)使(shi)(shi)(shi)用(yong)(yong)水(shui)(shui)或水(shui)(shui)清(qing)(qing)洗(xi)(xi)(xi)(xi)劑時(shi)(shi)由空穴作用(yong)(yong)引(yin)起的(de)(de)物(wu)理(li)清(qing)(qing)洗(xi)(xi)(xi)(xi)力顯然對(dui)低頻(pin)(pin)(pin)有(you)(you)(you)(you)利(li),一(yi)(yi)(yi)般使(shi)(shi)(shi)用(yong)(yong)28-40kHz左右。對(dui)小(xiao)間隙、狹縫、深孔(kong)的(de)(de)零件(jian)清(qing)(qing)洗(xi)(xi)(xi)(xi),用(yong)(yong)高頻(pin)(pin)(pin)(一(yi)(yi)(yi)般40kHz以上)較好(hao),甚(shen)至幾百kHz。對(dui)鐘(zhong)表零件(jian)清(qing)(qing)洗(xi)(xi)(xi)(xi)時(shi)(shi),用(yong)(yong)400kHz。若用(yong)(yong)寬帶(dai)調頻(pin)(pin)(pin)清(qing)(qing)洗(xi)(xi)(xi)(xi),效(xiao)果(guo)(guo)(guo)更(geng)良好(hao)。 三、清(qing)(qing)洗(xi)(xi)(xi)(xi)籃的(de)(de)使(shi)(shi)(shi)用(yong)(yong) 在(zai)清(qing)(qing)洗(xi)(xi)(xi)(xi)小(xiao)零件(jian)物(wu)品(pin)時(shi)(shi),常使(shi)(shi)(shi)用(yong)(yong)網籃,由于(yu)(yu)網眼(yan)要(yao)引(yin)起超(chao)聲(sheng)衰減(jian),要(yao)特別引(yin)起注意。當頻(pin)(pin)(pin)率(lv)(lv)(lv)為(wei)(wei)28khz時(shi)(shi)使(shi)(shi)(shi)用(yong)(yong)10mm以上的(de)(de)網眼(yan)為(wei)(wei)好(hao)。 四(si)、清(qing)(qing)洗(xi)(xi)(xi)(xi)液溫度(du)的(de)(de)選(xuan)擇(ze) 水(shui)(shui)清(qing)(qing)洗(xi)(xi)(xi)(xi)液最適宜(yi)的(de)(de)清(qing)(qing)洗(xi)(xi)(xi)(xi)溫度(du)為(wei)(wei)40-60℃,尤其在(zai)天冷時(shi)(shi)若清(qing)(qing)洗(xi)(xi)(xi)(xi)液溫度(du)低空化效(xiao)應差,清(qing)(qing)洗(xi)(xi)(xi)(xi)效(xiao)果(guo)(guo)(guo)也(ye)差。因此有(you)(you)(you)(you)部分清(qing)(qing)洗(xi)(xi)(xi)(xi)機在(zai)清(qing)(qing)洗(xi)(xi)(xi)(xi)缸(gang)外邊(bian)繞(rao)上加熱(re)電熱(re)絲進行溫度(du)控制,當溫度(du)升高后空化易發生,所以清(qing)(qing)洗(xi)(xi)(xi)(xi)...
