一(yi)(yi)、功(gong)率的(de)(de)(de)(de)(de)選(xuan)擇 超(chao)聲波(bo)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)效果(guo)不一(yi)(yi)定與(功(gong)率×清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)時(shi)間)成正比,有時(shi)用(yong)(yong)(yong)(yong)(yong)小(xiao)功(gong)率,花(hua)費很長時(shi)間也沒有清(qing)(qing)(qing)(qing)除污(wu)垢。而如果(guo)功(gong)率達到(dao)一(yi)(yi)定數值,有時(shi)很快(kuai)便將污(wu)垢去除。若(ruo)選(xuan)擇功(gong)率太大(da),空(kong)化(hua)強(qiang)度(du)將大(da)大(da)增加(jia),清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)效果(guo)是提高(gao)了(le),但(dan)這時(shi)使(shi)(shi)較精密的(de)(de)(de)(de)(de)零件也產生蝕點(dian)(dian),得不償失,而且清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)缸底部(bu)振動板(ban)處空(kong)化(hua)嚴重,水(shui)(shui)點(dian)(dian)腐蝕也增大(da),在采用(yong)(yong)(yong)(yong)(yong)三氯乙烯等有機(ji)溶劑時(shi),基本上(shang)沒有問(wen)題,但(dan)采用(yong)(yong)(yong)(yong)(yong)水(shui)(shui)或水(shui)(shui)溶性清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)液(ye)時(shi),易于受到(dao)水(shui)(shui)點(dian)(dian)腐蝕,如果(guo)振動板(ban)表(biao)面已受到(dao)傷(shang)痕,強(qiang)功(gong)率下(xia)水(shui)(shui)底產生空(kong)化(hua)腐蝕更嚴重,因(yin)此要(yao)按實際使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)情況選(xuan)擇超(chao)聲功(gong)率。 二(er)、頻(pin)(pin)率的(de)(de)(de)(de)(de)選(xuan)擇 超(chao)聲清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)頻(pin)(pin)率從28kHz到(dao)120kHz之(zhi)間,在使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)水(shui)(shui)或水(shui)(shui)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)劑時(shi)由(you)空(kong)穴作用(yong)(yong)(yong)(yong)(yong)引(yin)起(qi)的(de)(de)(de)(de)(de)物理清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)力顯然對低頻(pin)(pin)有利,一(yi)(yi)般(ban)使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)28-40kHz左(zuo)右(you)。對小(xiao)間隙、狹縫、深孔的(de)(de)(de)(de)(de)零件清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi),用(yong)(yong)(yong)(yong)(yong)高(gao)頻(pin)(pin)(一(yi)(yi)般(ban)40kHz以上(shang))較好(hao)(hao),甚至幾百kHz。對鐘表(biao)零件清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)時(shi),用(yong)(yong)(yong)(yong)(yong)400kHz。若(ruo)用(yong)(yong)(yong)(yong)(yong)寬(kuan)帶調頻(pin)(pin)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi),效果(guo)更良好(hao)(hao)。 三、清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)籃(lan)的(de)(de)(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)(yong)(yong) 在清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)小(xiao)零件物品時(shi),常使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)網籃(lan),由(you)于網眼要(yao)引(yin)起(qi)超(chao)聲衰減,要(yao)特(te)別(bie)引(yin)起(qi)注意(yi)。當頻(pin)(pin)率為28khz時(shi)使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)10mm以上(shang)的(de)(de)(de)(de)(de)網眼為好(hao)(hao)。 四、清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)液(ye)溫(wen)(wen)(wen)(wen)度(du)的(de)(de)(de)(de)(de)選(xuan)擇 水(shui)(shui)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)液(ye)最適宜的(de)(de)(de)(de)(de)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)溫(wen)(wen)(wen)(wen)度(du)為40-60℃,尤(you)其在天冷時(shi)若(ruo)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)液(ye)溫(wen)(wen)(wen)(wen)度(du)低空(kong)化(hua)效應差,清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)效果(guo)也差。因(yin)此有部(bu)分清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)機(ji)在清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)缸外邊繞(rao)上(shang)加(jia)熱(re)電熱(re)絲進(jin)行溫(wen)(wen)(wen)(wen)度(du)控制,當溫(wen)(wen)(wen)(wen)度(du)升高(gao)后空(kong)化(hua)易發生,所以清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)...
