一(yi)(yi)、功(gong)(gong)率(lv)(lv)的(de)(de)選(xuan)(xuan)擇 超(chao)聲波清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效(xiao)(xiao)果不一(yi)(yi)定(ding)與(yu)(功(gong)(gong)率(lv)(lv)×清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)時(shi)(shi)(shi)間)成正比,有(you)時(shi)(shi)(shi)用(yong)(yong)小(xiao)功(gong)(gong)率(lv)(lv),花費(fei)很長時(shi)(shi)(shi)間也沒(mei)有(you)清(qing)(qing)(qing)(qing)(qing)除污垢(gou)。而如果功(gong)(gong)率(lv)(lv)達到一(yi)(yi)定(ding)數值,有(you)時(shi)(shi)(shi)很快(kuai)便將(jiang)(jiang)污垢(gou)去(qu)除。若選(xuan)(xuan)擇功(gong)(gong)率(lv)(lv)太大(da),空(kong)化(hua)(hua)(hua)強度(du)(du)將(jiang)(jiang)大(da)大(da)增(zeng)加,清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效(xiao)(xiao)果是提高(gao)了,但(dan)這時(shi)(shi)(shi)使(shi)(shi)(shi)較精密(mi)的(de)(de)零(ling)件也產生蝕(shi)點,得(de)不償失,而且清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)缸(gang)底部振動板處空(kong)化(hua)(hua)(hua)嚴重,水(shui)(shui)(shui)點腐(fu)蝕(shi)也增(zeng)大(da),在采用(yong)(yong)三氯乙(yi)烯等有(you)機溶(rong)劑時(shi)(shi)(shi),基本(ben)上沒(mei)有(you)問題(ti),但(dan)采用(yong)(yong)水(shui)(shui)(shui)或水(shui)(shui)(shui)溶(rong)性清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)時(shi)(shi)(shi),易于受(shou)到水(shui)(shui)(shui)點腐(fu)蝕(shi),如果振動板表面已受(shou)到傷痕,強功(gong)(gong)率(lv)(lv)下水(shui)(shui)(shui)底產生空(kong)化(hua)(hua)(hua)腐(fu)蝕(shi)更(geng)嚴重,因(yin)(yin)此要按(an)實(shi)際使(shi)(shi)(shi)用(yong)(yong)情況(kuang)選(xuan)(xuan)擇超(chao)聲功(gong)(gong)率(lv)(lv)。 二(er)、頻率(lv)(lv)的(de)(de)選(xuan)(xuan)擇 超(chao)聲清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)頻率(lv)(lv)從28kHz到120kHz之(zhi)間,在使(shi)(shi)(shi)用(yong)(yong)水(shui)(shui)(shui)或水(shui)(shui)(shui)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)劑時(shi)(shi)(shi)由空(kong)穴作(zuo)用(yong)(yong)引(yin)起(qi)的(de)(de)物(wu)理清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)力顯然(ran)對(dui)(dui)低頻有(you)利,一(yi)(yi)般(ban)使(shi)(shi)(shi)用(yong)(yong)28-40kHz左右。對(dui)(dui)小(xiao)間隙、狹縫、深孔的(de)(de)零(ling)件清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi),用(yong)(yong)高(gao)頻(一(yi)(yi)般(ban)40kHz以上)較好(hao),甚至幾百kHz。對(dui)(dui)鐘(zhong)表零(ling)件清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)時(shi)(shi)(shi),用(yong)(yong)400kHz。若用(yong)(yong)寬帶調頻清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi),效(xiao)(xiao)果更(geng)良好(hao)。 三、清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)籃(lan)的(de)(de)使(shi)(shi)(shi)用(yong)(yong) 在清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)小(xiao)零(ling)件物(wu)品時(shi)(shi)(shi),常使(shi)(shi)(shi)用(yong)(yong)網(wang)籃(lan),由于網(wang)眼要引(yin)起(qi)超(chao)聲衰(shuai)減,要特別引(yin)起(qi)注(zhu)意。當頻率(lv)(lv)為28khz時(shi)(shi)(shi)使(shi)(shi)(shi)用(yong)(yong)10mm以上的(de)(de)網(wang)眼為好(hao)。 四、清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)溫(wen)度(du)(du)的(de)(de)選(xuan)(xuan)擇 水(shui)(shui)(shui)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)最適宜的(de)(de)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)溫(wen)度(du)(du)為40-60℃,尤其在天冷時(shi)(shi)(shi)若清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)溫(wen)度(du)(du)低空(kong)化(hua)(hua)(hua)效(xiao)(xiao)應(ying)差(cha),清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效(xiao)(xiao)果也差(cha)。因(yin)(yin)此有(you)部分清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)機在清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)缸(gang)外(wai)邊繞(rao)上加熱電熱絲進(jin)行溫(wen)度(du)(du)控制,當溫(wen)度(du)(du)升高(gao)后空(kong)化(hua)(hua)(hua)易發生,所以清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)...
