一(yi)(yi)(yi)、功率(lv)的選擇(ze) 超(chao)(chao)聲波清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)效(xiao)果不一(yi)(yi)(yi)定與(功率(lv)×清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)時(shi)(shi)(shi)(shi)(shi)間)成正(zheng)比,有(you)時(shi)(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)小(xiao)(xiao)功率(lv),花費很(hen)長時(shi)(shi)(shi)(shi)(shi)間也(ye)沒有(you)清(qing)(qing)(qing)除(chu)污垢。而如(ru)果功率(lv)達到(dao)(dao)(dao)一(yi)(yi)(yi)定數值,有(you)時(shi)(shi)(shi)(shi)(shi)很(hen)快便將污垢去除(chu)。若選擇(ze)功率(lv)太(tai)大(da),空(kong)化(hua)強(qiang)度將大(da)大(da)增加,清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)效(xiao)果是提高了,但(dan)這時(shi)(shi)(shi)(shi)(shi)使(shi)較(jiao)精密的零件(jian)也(ye)產生(sheng)蝕點(dian)(dian),得不償失,而且清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)缸底部(bu)振動板處空(kong)化(hua)嚴(yan)重,水(shui)(shui)(shui)點(dian)(dian)腐蝕也(ye)增大(da),在(zai)(zai)采用(yong)(yong)(yong)(yong)(yong)三氯乙烯等(deng)有(you)機溶(rong)劑(ji)時(shi)(shi)(shi)(shi)(shi),基本(ben)上沒有(you)問(wen)題,但(dan)采用(yong)(yong)(yong)(yong)(yong)水(shui)(shui)(shui)或水(shui)(shui)(shui)溶(rong)性清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)液時(shi)(shi)(shi)(shi)(shi),易(yi)于受(shou)到(dao)(dao)(dao)水(shui)(shui)(shui)點(dian)(dian)腐蝕,如(ru)果振動板表面已受(shou)到(dao)(dao)(dao)傷痕(hen),強(qiang)功率(lv)下水(shui)(shui)(shui)底產生(sheng)空(kong)化(hua)腐蝕更(geng)嚴(yan)重,因(yin)(yin)此要(yao)按實(shi)際使(shi)用(yong)(yong)(yong)(yong)(yong)情況選擇(ze)超(chao)(chao)聲功率(lv)。 二、頻(pin)率(lv)的選擇(ze) 超(chao)(chao)聲清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)頻(pin)率(lv)從(cong)28kHz到(dao)(dao)(dao)120kHz之間,在(zai)(zai)使(shi)用(yong)(yong)(yong)(yong)(yong)水(shui)(shui)(shui)或水(shui)(shui)(shui)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)劑(ji)時(shi)(shi)(shi)(shi)(shi)由空(kong)穴作用(yong)(yong)(yong)(yong)(yong)引(yin)(yin)起(qi)的物理清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)力顯(xian)然對(dui)(dui)低頻(pin)有(you)利,一(yi)(yi)(yi)般使(shi)用(yong)(yong)(yong)(yong)(yong)28-40kHz左(zuo)右。對(dui)(dui)小(xiao)(xiao)間隙、狹(xia)縫、深孔的零件(jian)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi),用(yong)(yong)(yong)(yong)(yong)高頻(pin)(一(yi)(yi)(yi)般40kHz以(yi)上)較(jiao)好,甚(shen)至幾(ji)百kHz。對(dui)(dui)鐘表零件(jian)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)時(shi)(shi)(shi)(shi)(shi),用(yong)(yong)(yong)(yong)(yong)400kHz。若用(yong)(yong)(yong)(yong)(yong)寬(kuan)帶調頻(pin)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi),效(xiao)果更(geng)良好。 三、清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)籃的使(shi)用(yong)(yong)(yong)(yong)(yong) 在(zai)(zai)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)小(xiao)(xiao)零件(jian)物品時(shi)(shi)(shi)(shi)(shi),常使(shi)用(yong)(yong)(yong)(yong)(yong)網籃,由于網眼要(yao)引(yin)(yin)起(qi)超(chao)(chao)聲衰減,要(yao)特別(bie)引(yin)(yin)起(qi)注(zhu)意。當頻(pin)率(lv)為(wei)28khz時(shi)(shi)(shi)(shi)(shi)使(shi)用(yong)(yong)(yong)(yong)(yong)10mm以(yi)上的網眼為(wei)好。 四、清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)液溫(wen)(wen)度的選擇(ze) 水(shui)(shui)(shui)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)液最適宜的清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)溫(wen)(wen)度為(wei)40-60℃,尤其在(zai)(zai)天冷時(shi)(shi)(shi)(shi)(shi)若清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)液溫(wen)(wen)度低空(kong)化(hua)效(xiao)應差(cha),清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)效(xiao)果也(ye)差(cha)。因(yin)(yin)此有(you)部(bu)分清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)機在(zai)(zai)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)缸外邊繞上加熱(re)電熱(re)絲進(jin)行(xing)溫(wen)(wen)度控制,當溫(wen)(wen)度升高后空(kong)化(hua)易(yi)發生(sheng),所以(yi)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)...
