一(yi)(yi)、功(gong)率(lv)(lv)的(de)(de)選擇 超聲波清(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)效果不一(yi)(yi)定與(功(gong)率(lv)(lv)×清(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)時(shi)(shi)間(jian))成(cheng)正比,有時(shi)(shi)用(yong)(yong)小(xiao)功(gong)率(lv)(lv),花費很(hen)長時(shi)(shi)間(jian)也(ye)沒(mei)有清(qing)(qing)除污垢。而(er)如果功(gong)率(lv)(lv)達到一(yi)(yi)定數值,有時(shi)(shi)很(hen)快(kuai)便將污垢去(qu)除。若選擇功(gong)率(lv)(lv)太大(da),空(kong)(kong)化強度(du)(du)將大(da)大(da)增(zeng)加,清(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)效果是(shi)提高了,但這時(shi)(shi)使(shi)較精密的(de)(de)零件也(ye)產生(sheng)蝕(shi)點(dian),得不償失,而(er)且清(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)缸底(di)部(bu)振(zhen)動板處空(kong)(kong)化嚴(yan)重,水(shui)點(dian)腐蝕(shi)也(ye)增(zeng)大(da),在(zai)(zai)采用(yong)(yong)三氯乙烯等有機溶(rong)劑(ji)時(shi)(shi),基本上沒(mei)有問題,但采用(yong)(yong)水(shui)或水(shui)溶(rong)性(xing)清(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)液時(shi)(shi),易于受到水(shui)點(dian)腐蝕(shi),如果振(zhen)動板表面(mian)已受到傷痕,強功(gong)率(lv)(lv)下水(shui)底(di)產生(sheng)空(kong)(kong)化腐蝕(shi)更嚴(yan)重,因此要(yao)按實(shi)際使(shi)用(yong)(yong)情況選擇超聲功(gong)率(lv)(lv)。 二、頻(pin)(pin)率(lv)(lv)的(de)(de)選擇 超聲清(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)頻(pin)(pin)率(lv)(lv)從28kHz到120kHz之間(jian),在(zai)(zai)使(shi)用(yong)(yong)水(shui)或水(shui)清(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)劑(ji)時(shi)(shi)由空(kong)(kong)穴作用(yong)(yong)引起的(de)(de)物(wu)理清(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)力顯然對低頻(pin)(pin)有利,一(yi)(yi)般使(shi)用(yong)(yong)28-40kHz左右。對小(xiao)間(jian)隙、狹縫(feng)、深孔的(de)(de)零件清(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi),用(yong)(yong)高頻(pin)(pin)(一(yi)(yi)般40kHz以(yi)上)較好,甚(shen)至幾(ji)百kHz。對鐘表零件清(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)時(shi)(shi),用(yong)(yong)400kHz。若用(yong)(yong)寬帶調(diao)頻(pin)(pin)清(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi),效果更良好。 三、清(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)籃的(de)(de)使(shi)用(yong)(yong) 在(zai)(zai)清(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)小(xiao)零件物(wu)品時(shi)(shi),常使(shi)用(yong)(yong)網(wang)籃,由于網(wang)眼要(yao)引起超聲衰(shuai)減,要(yao)特別引起注(zhu)意。當頻(pin)(pin)率(lv)(lv)為28khz時(shi)(shi)使(shi)用(yong)(yong)10mm以(yi)上的(de)(de)網(wang)眼為好。 四、清(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)液溫度(du)(du)的(de)(de)選擇 水(shui)清(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)液最適宜的(de)(de)清(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)溫度(du)(du)為40-60℃,尤(you)其(qi)在(zai)(zai)天冷時(shi)(shi)若清(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)液溫度(du)(du)低空(kong)(kong)化效應(ying)差,清(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)效果也(ye)差。因此有部(bu)分清(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)機在(zai)(zai)清(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)缸外邊繞(rao)上加熱電(dian)熱絲進(jin)行溫度(du)(du)控制,當溫度(du)(du)升高后(hou)空(kong)(kong)化易發生(sheng),所以(yi)清(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)...
