一(yi)(yi)、功(gong)率(lv)(lv)(lv)(lv)的(de)(de)選擇(ze) 超(chao)聲(sheng)(sheng)(sheng)波(bo)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)效果(guo)(guo)不一(yi)(yi)定與(yu)(功(gong)率(lv)(lv)(lv)(lv)×清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)時(shi)(shi)間(jian))成正比,有(you)(you)時(shi)(shi)用(yong)(yong)(yong)(yong)小(xiao)功(gong)率(lv)(lv)(lv)(lv),花(hua)費很長時(shi)(shi)間(jian)也(ye)沒有(you)(you)清(qing)(qing)(qing)(qing)(qing)除(chu)污垢。而(er)如(ru)果(guo)(guo)功(gong)率(lv)(lv)(lv)(lv)達到一(yi)(yi)定數值,有(you)(you)時(shi)(shi)很快便將(jiang)污垢去除(chu)。若(ruo)選擇(ze)功(gong)率(lv)(lv)(lv)(lv)太大(da)(da),空(kong)化(hua)(hua)強度(du)(du)(du)將(jiang)大(da)(da)大(da)(da)增加,清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)效果(guo)(guo)是(shi)提高了,但這時(shi)(shi)使(shi)(shi)(shi)(shi)較精密的(de)(de)零件(jian)也(ye)產生蝕(shi)(shi)點,得不償(chang)失,而(er)且清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)缸底部(bu)振動板處空(kong)化(hua)(hua)嚴重,水(shui)點腐(fu)蝕(shi)(shi)也(ye)增大(da)(da),在(zai)(zai)采用(yong)(yong)(yong)(yong)三氯乙(yi)烯(xi)等(deng)有(you)(you)機溶(rong)劑時(shi)(shi),基本上(shang)沒有(you)(you)問(wen)題,但采用(yong)(yong)(yong)(yong)水(shui)或水(shui)溶(rong)性清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)液(ye)(ye)時(shi)(shi),易(yi)于受(shou)到水(shui)點腐(fu)蝕(shi)(shi),如(ru)果(guo)(guo)振動板表面已受(shou)到傷痕,強功(gong)率(lv)(lv)(lv)(lv)下(xia)水(shui)底產生空(kong)化(hua)(hua)腐(fu)蝕(shi)(shi)更嚴重,因此要按實際(ji)使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)情況選擇(ze)超(chao)聲(sheng)(sheng)(sheng)功(gong)率(lv)(lv)(lv)(lv)。 二、頻(pin)(pin)率(lv)(lv)(lv)(lv)的(de)(de)選擇(ze) 超(chao)聲(sheng)(sheng)(sheng)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)頻(pin)(pin)率(lv)(lv)(lv)(lv)從28kHz到120kHz之間(jian),在(zai)(zai)使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)水(shui)或水(shui)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)劑時(shi)(shi)由空(kong)穴作用(yong)(yong)(yong)(yong)引起的(de)(de)物理清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)力顯然對低(di)頻(pin)(pin)有(you)(you)利(li),一(yi)(yi)般使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)28-40kHz左右。對小(xiao)間(jian)隙、狹(xia)縫、深(shen)孔的(de)(de)零件(jian)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi),用(yong)(yong)(yong)(yong)高頻(pin)(pin)(一(yi)(yi)般40kHz以(yi)上(shang))較好,甚至(zhi)幾百(bai)kHz。對鐘表零件(jian)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)時(shi)(shi),用(yong)(yong)(yong)(yong)400kHz。若(ruo)用(yong)(yong)(yong)(yong)寬帶(dai)調頻(pin)(pin)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi),效果(guo)(guo)更良好。 三、清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)籃的(de)(de)使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong) 在(zai)(zai)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)小(xiao)零件(jian)物品時(shi)(shi),常使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)網籃,由于網眼要引起超(chao)聲(sheng)(sheng)(sheng)衰(shuai)減,要特別引起注意(yi)。當(dang)頻(pin)(pin)率(lv)(lv)(lv)(lv)為28khz時(shi)(shi)使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)10mm以(yi)上(shang)的(de)(de)網眼為好。 四、清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)液(ye)(ye)溫(wen)(wen)度(du)(du)(du)的(de)(de)選擇(ze) 水(shui)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)液(ye)(ye)最適(shi)宜的(de)(de)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)溫(wen)(wen)度(du)(du)(du)為40-60℃,尤其在(zai)(zai)天(tian)冷時(shi)(shi)若(ruo)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)液(ye)(ye)溫(wen)(wen)度(du)(du)(du)低(di)空(kong)化(hua)(hua)效應(ying)差,清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)效果(guo)(guo)也(ye)差。因此有(you)(you)部(bu)分(fen)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)機在(zai)(zai)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)缸外邊繞上(shang)加熱電(dian)熱絲(si)進行溫(wen)(wen)度(du)(du)(du)控制,當(dang)溫(wen)(wen)度(du)(du)(du)升(sheng)高后空(kong)化(hua)(hua)易(yi)發(fa)生,所以(yi)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)...
