一(yi)(yi)(yi)、功(gong)(gong)率(lv)(lv)(lv)(lv)的(de)選(xuan)擇(ze)(ze) 超(chao)聲(sheng)波清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)效(xiao)果(guo)(guo)不一(yi)(yi)(yi)定與(功(gong)(gong)率(lv)(lv)(lv)(lv)×清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)時(shi)(shi)(shi)(shi)(shi)間(jian))成正比,有(you)時(shi)(shi)(shi)(shi)(shi)用(yong)小功(gong)(gong)率(lv)(lv)(lv)(lv),花費很長時(shi)(shi)(shi)(shi)(shi)間(jian)也(ye)沒有(you)清(qing)(qing)(qing)(qing)(qing)(qing)除污垢。而(er)如(ru)果(guo)(guo)功(gong)(gong)率(lv)(lv)(lv)(lv)達到(dao)一(yi)(yi)(yi)定數值,有(you)時(shi)(shi)(shi)(shi)(shi)很快(kuai)便將污垢去除。若(ruo)選(xuan)擇(ze)(ze)功(gong)(gong)率(lv)(lv)(lv)(lv)太大(da),空(kong)(kong)化(hua)(hua)(hua)強度(du)將大(da)大(da)增(zeng)(zeng)加(jia),清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)效(xiao)果(guo)(guo)是提高了,但這時(shi)(shi)(shi)(shi)(shi)使(shi)較(jiao)精密的(de)零件也(ye)產(chan)生蝕點(dian),得(de)不償失(shi),而(er)且清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)缸底(di)部振(zhen)動板處空(kong)(kong)化(hua)(hua)(hua)嚴重(zhong),水(shui)點(dian)腐蝕也(ye)增(zeng)(zeng)大(da),在(zai)(zai)采(cai)用(yong)三(san)氯(lv)乙烯等(deng)有(you)機(ji)溶(rong)劑時(shi)(shi)(shi)(shi)(shi),基本(ben)上(shang)(shang)沒有(you)問題,但采(cai)用(yong)水(shui)或(huo)水(shui)溶(rong)性清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)液(ye)時(shi)(shi)(shi)(shi)(shi),易(yi)于(yu)受到(dao)水(shui)點(dian)腐蝕,如(ru)果(guo)(guo)振(zhen)動板表面已受到(dao)傷(shang)痕,強功(gong)(gong)率(lv)(lv)(lv)(lv)下(xia)水(shui)底(di)產(chan)生空(kong)(kong)化(hua)(hua)(hua)腐蝕更(geng)嚴重(zhong),因(yin)此要(yao)按實際使(shi)用(yong)情況選(xuan)擇(ze)(ze)超(chao)聲(sheng)功(gong)(gong)率(lv)(lv)(lv)(lv)。 二、頻(pin)(pin)(pin)率(lv)(lv)(lv)(lv)的(de)選(xuan)擇(ze)(ze) 超(chao)聲(sheng)清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)頻(pin)(pin)(pin)率(lv)(lv)(lv)(lv)從(cong)28kHz到(dao)120kHz之間(jian),在(zai)(zai)使(shi)用(yong)水(shui)或(huo)水(shui)清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)劑時(shi)(shi)(shi)(shi)(shi)由(you)空(kong)(kong)穴作用(yong)引起(qi)的(de)物(wu)(wu)理清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)力顯然(ran)對低頻(pin)(pin)(pin)有(you)利(li),一(yi)(yi)(yi)般使(shi)用(yong)28-40kHz左(zuo)右。對小間(jian)隙、狹縫、深孔(kong)的(de)零件清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi),用(yong)高頻(pin)(pin)(pin)(一(yi)(yi)(yi)般40kHz以(yi)上(shang)(shang))較(jiao)好(hao)(hao),甚(shen)至幾百(bai)kHz。對鐘表零件清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)時(shi)(shi)(shi)(shi)(shi),用(yong)400kHz。若(ruo)用(yong)寬帶調頻(pin)(pin)(pin)清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi),效(xiao)果(guo)(guo)更(geng)良(liang)好(hao)(hao)。 三(san)、清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)籃的(de)使(shi)用(yong) 在(zai)(zai)清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)小零件物(wu)(wu)品時(shi)(shi)(shi)(shi)(shi),常使(shi)用(yong)網籃,由(you)于(yu)網眼要(yao)引起(qi)超(chao)聲(sheng)衰減(jian),要(yao)特別引起(qi)注意。當頻(pin)(pin)(pin)率(lv)(lv)(lv)(lv)為28khz時(shi)(shi)(shi)(shi)(shi)使(shi)用(yong)10mm以(yi)上(shang)(shang)的(de)網眼為好(hao)(hao)。 四、清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)液(ye)溫度(du)的(de)選(xuan)擇(ze)(ze) 水(shui)清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)液(ye)最適宜的(de)清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)溫度(du)為40-60℃,尤其在(zai)(zai)天(tian)冷時(shi)(shi)(shi)(shi)(shi)若(ruo)清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)液(ye)溫度(du)低空(kong)(kong)化(hua)(hua)(hua)效(xiao)應(ying)差,清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)效(xiao)果(guo)(guo)也(ye)差。因(yin)此有(you)部分清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)機(ji)在(zai)(zai)清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)缸外邊繞上(shang)(shang)加(jia)熱電(dian)熱絲(si)進(jin)行溫度(du)控制,當溫度(du)升高后空(kong)(kong)化(hua)(hua)(hua)易(yi)發生,所以(yi)清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)...
