一、功(gong)(gong)率(lv)的選擇(ze) 超(chao)聲波(bo)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)效(xiao)果(guo)(guo)不(bu)(bu)一定與(功(gong)(gong)率(lv)×清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)時(shi)間)成正比,有(you)時(shi)用(yong)(yong)(yong)(yong)(yong)小(xiao)(xiao)功(gong)(gong)率(lv),花費很(hen)(hen)長時(shi)間也(ye)沒有(you)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)除(chu)污(wu)(wu)垢。而(er)如果(guo)(guo)功(gong)(gong)率(lv)達到(dao)一定數值(zhi),有(you)時(shi)很(hen)(hen)快便將污(wu)(wu)垢去除(chu)。若選擇(ze)功(gong)(gong)率(lv)太大(da),空(kong)化強(qiang)度將大(da)大(da)增(zeng)加(jia),清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)效(xiao)果(guo)(guo)是提高了(le),但(dan)這(zhe)時(shi)使(shi)較精密的零件(jian)也(ye)產生(sheng)蝕點(dian),得不(bu)(bu)償失,而(er)且清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)缸(gang)底部振(zhen)動板處(chu)空(kong)化嚴重(zhong)(zhong),水(shui)點(dian)腐蝕也(ye)增(zeng)大(da),在采用(yong)(yong)(yong)(yong)(yong)三(san)氯乙烯等有(you)機溶(rong)劑(ji)時(shi),基本上沒有(you)問題,但(dan)采用(yong)(yong)(yong)(yong)(yong)水(shui)或水(shui)溶(rong)性清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)液(ye)時(shi),易于受到(dao)水(shui)點(dian)腐蝕,如果(guo)(guo)振(zhen)動板表(biao)面已受到(dao)傷痕,強(qiang)功(gong)(gong)率(lv)下水(shui)底產生(sheng)空(kong)化腐蝕更(geng)嚴重(zhong)(zhong),因(yin)此要(yao)按實際(ji)使(shi)用(yong)(yong)(yong)(yong)(yong)情況選擇(ze)超(chao)聲功(gong)(gong)率(lv)。 二、頻(pin)(pin)率(lv)的選擇(ze) 超(chao)聲清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)頻(pin)(pin)率(lv)從(cong)28kHz到(dao)120kHz之間,在使(shi)用(yong)(yong)(yong)(yong)(yong)水(shui)或水(shui)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)劑(ji)時(shi)由(you)空(kong)穴作用(yong)(yong)(yong)(yong)(yong)引(yin)(yin)起的物理(li)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)力(li)顯然對(dui)低(di)頻(pin)(pin)有(you)利,一般(ban)使(shi)用(yong)(yong)(yong)(yong)(yong)28-40kHz左右。對(dui)小(xiao)(xiao)間隙(xi)、狹縫、深孔的零件(jian)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi),用(yong)(yong)(yong)(yong)(yong)高頻(pin)(pin)(一般(ban)40kHz以上)較好,甚(shen)至幾(ji)百kHz。對(dui)鐘表(biao)零件(jian)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)時(shi),用(yong)(yong)(yong)(yong)(yong)400kHz。若用(yong)(yong)(yong)(yong)(yong)寬帶調頻(pin)(pin)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi),效(xiao)果(guo)(guo)更(geng)良好。 三(san)、清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)籃的使(shi)用(yong)(yong)(yong)(yong)(yong) 在清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)小(xiao)(xiao)零件(jian)物品時(shi),常使(shi)用(yong)(yong)(yong)(yong)(yong)網(wang)籃,由(you)于網(wang)眼要(yao)引(yin)(yin)起超(chao)聲衰減,要(yao)特別引(yin)(yin)起注意(yi)。當頻(pin)(pin)率(lv)為(wei)28khz時(shi)使(shi)用(yong)(yong)(yong)(yong)(yong)10mm以上的網(wang)眼為(wei)好。 四、清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)液(ye)溫(wen)度的選擇(ze) 水(shui)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)液(ye)最適宜(yi)的清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)溫(wen)度為(wei)40-60℃,尤其在天(tian)冷時(shi)若清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)液(ye)溫(wen)度低(di)空(kong)化效(xiao)應(ying)差(cha),清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)效(xiao)果(guo)(guo)也(ye)差(cha)。因(yin)此有(you)部分清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)機在清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)缸(gang)外邊繞上加(jia)熱電熱絲進行溫(wen)度控制,當溫(wen)度升高后空(kong)化易發生(sheng),所以清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)...
