一、功率(lv)(lv)的(de)(de)(de)選擇(ze)(ze) 超聲波(bo)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)效(xiao)(xiao)果(guo)不(bu)一定(ding)(ding)與(yu)(功率(lv)(lv)×清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)時(shi)(shi)(shi)(shi)間(jian)(jian))成正比,有(you)(you)時(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)小功率(lv)(lv),花費很長時(shi)(shi)(shi)(shi)間(jian)(jian)也沒有(you)(you)清(qing)(qing)(qing)(qing)除污垢。而如(ru)果(guo)功率(lv)(lv)達到(dao)一定(ding)(ding)數值,有(you)(you)時(shi)(shi)(shi)(shi)很快便將(jiang)污垢去除。若選擇(ze)(ze)功率(lv)(lv)太大(da),空(kong)化強度(du)將(jiang)大(da)大(da)增加,清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)效(xiao)(xiao)果(guo)是提高(gao)了(le),但這時(shi)(shi)(shi)(shi)使(shi)(shi)較(jiao)精(jing)密的(de)(de)(de)零件(jian)也產生蝕(shi)點,得(de)不(bu)償(chang)失,而且清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)缸底(di)部振動板處空(kong)化嚴重,水(shui)(shui)(shui)點腐蝕(shi)也增大(da),在(zai)采用(yong)(yong)(yong)(yong)(yong)三氯乙烯等有(you)(you)機(ji)溶劑(ji)時(shi)(shi)(shi)(shi),基本上(shang)(shang)沒有(you)(you)問(wen)題,但采用(yong)(yong)(yong)(yong)(yong)水(shui)(shui)(shui)或水(shui)(shui)(shui)溶性清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)液時(shi)(shi)(shi)(shi),易(yi)(yi)于(yu)受到(dao)水(shui)(shui)(shui)點腐蝕(shi),如(ru)果(guo)振動板表面已受到(dao)傷痕,強功率(lv)(lv)下水(shui)(shui)(shui)底(di)產生空(kong)化腐蝕(shi)更嚴重,因(yin)此要按實際使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)情(qing)況(kuang)選擇(ze)(ze)超聲功率(lv)(lv)。 二、頻率(lv)(lv)的(de)(de)(de)選擇(ze)(ze) 超聲清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)頻率(lv)(lv)從28kHz到(dao)120kHz之間(jian)(jian),在(zai)使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)水(shui)(shui)(shui)或水(shui)(shui)(shui)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)劑(ji)時(shi)(shi)(shi)(shi)由(you)空(kong)穴作用(yong)(yong)(yong)(yong)(yong)引起(qi)的(de)(de)(de)物(wu)理清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)力顯然對(dui)低頻有(you)(you)利,一般使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)28-40kHz左右(you)。對(dui)小間(jian)(jian)隙、狹縫、深孔的(de)(de)(de)零件(jian)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi),用(yong)(yong)(yong)(yong)(yong)高(gao)頻(一般40kHz以(yi)上(shang)(shang))較(jiao)好(hao),甚(shen)至幾百kHz。對(dui)鐘表零件(jian)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)時(shi)(shi)(shi)(shi),用(yong)(yong)(yong)(yong)(yong)400kHz。若用(yong)(yong)(yong)(yong)(yong)寬帶調頻清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi),效(xiao)(xiao)果(guo)更良好(hao)。 三、清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)籃的(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)(yong)(yong) 在(zai)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)小零件(jian)物(wu)品時(shi)(shi)(shi)(shi),常(chang)使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)網(wang)籃,由(you)于(yu)網(wang)眼(yan)要引起(qi)超聲衰減(jian),要特別(bie)引起(qi)注意。當(dang)頻率(lv)(lv)為28khz時(shi)(shi)(shi)(shi)使(shi)(shi)用(yong)(yong)(yong)(yong)(yong)10mm以(yi)上(shang)(shang)的(de)(de)(de)網(wang)眼(yan)為好(hao)。 四、清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)液溫度(du)的(de)(de)(de)選擇(ze)(ze) 水(shui)(shui)(shui)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)液最適(shi)宜的(de)(de)(de)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)溫度(du)為40-60℃,尤其在(zai)天(tian)冷時(shi)(shi)(shi)(shi)若清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)液溫度(du)低空(kong)化效(xiao)(xiao)應差(cha),清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)效(xiao)(xiao)果(guo)也差(cha)。因(yin)此有(you)(you)部分清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)機(ji)在(zai)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)缸外邊繞上(shang)(shang)加熱電熱絲進行溫度(du)控(kong)制(zhi),當(dang)溫度(du)升高(gao)后空(kong)化易(yi)(yi)發生,所以(yi)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)...
