一、功(gong)(gong)率(lv)(lv)的(de)(de)選(xuan)擇(ze) 超(chao)聲(sheng)波清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)效(xiao)(xiao)果(guo)不一定與(功(gong)(gong)率(lv)(lv)×清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)時(shi)(shi)間)成(cheng)正(zheng)比(bi),有時(shi)(shi)用(yong)(yong)小(xiao)功(gong)(gong)率(lv)(lv),花費很長(chang)時(shi)(shi)間也(ye)(ye)沒有清(qing)(qing)(qing)(qing)(qing)除污垢。而如(ru)果(guo)功(gong)(gong)率(lv)(lv)達(da)到一定數(shu)值,有時(shi)(shi)很快便將污垢去除。若選(xuan)擇(ze)功(gong)(gong)率(lv)(lv)太大(da),空化(hua)強(qiang)度將大(da)大(da)增加,清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)效(xiao)(xiao)果(guo)是提高了,但這(zhe)時(shi)(shi)使(shi)較精密的(de)(de)零(ling)件(jian)也(ye)(ye)產(chan)生(sheng)蝕(shi)點(dian)(dian),得不償(chang)失,而且清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)缸底部振動(dong)板(ban)處空化(hua)嚴重(zhong),水(shui)點(dian)(dian)腐蝕(shi)也(ye)(ye)增大(da),在(zai)(zai)采用(yong)(yong)三(san)氯(lv)乙烯等有機溶(rong)劑時(shi)(shi),基本上沒有問題,但采用(yong)(yong)水(shui)或水(shui)溶(rong)性清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)液時(shi)(shi),易于受到水(shui)點(dian)(dian)腐蝕(shi),如(ru)果(guo)振動(dong)板(ban)表面已受到傷痕,強(qiang)功(gong)(gong)率(lv)(lv)下(xia)水(shui)底產(chan)生(sheng)空化(hua)腐蝕(shi)更(geng)嚴重(zhong),因此要按實(shi)際使(shi)用(yong)(yong)情況選(xuan)擇(ze)超(chao)聲(sheng)功(gong)(gong)率(lv)(lv)。 二、頻率(lv)(lv)的(de)(de)選(xuan)擇(ze) 超(chao)聲(sheng)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)頻率(lv)(lv)從28kHz到120kHz之(zhi)間,在(zai)(zai)使(shi)用(yong)(yong)水(shui)或水(shui)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)劑時(shi)(shi)由空穴作用(yong)(yong)引(yin)(yin)起的(de)(de)物理清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)力顯(xian)然(ran)對低(di)頻有利,一般(ban)使(shi)用(yong)(yong)28-40kHz左右。對小(xiao)間隙(xi)、狹縫、深孔的(de)(de)零(ling)件(jian)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi),用(yong)(yong)高頻(一般(ban)40kHz以(yi)(yi)上)較好(hao),甚(shen)至幾百kHz。對鐘表零(ling)件(jian)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)時(shi)(shi),用(yong)(yong)400kHz。若用(yong)(yong)寬帶(dai)調頻清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi),效(xiao)(xiao)果(guo)更(geng)良好(hao)。 三(san)、清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)籃的(de)(de)使(shi)用(yong)(yong) 在(zai)(zai)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)小(xiao)零(ling)件(jian)物品時(shi)(shi),常使(shi)用(yong)(yong)網(wang)籃,由于網(wang)眼要引(yin)(yin)起超(chao)聲(sheng)衰減(jian),要特(te)別引(yin)(yin)起注意(yi)。當頻率(lv)(lv)為28khz時(shi)(shi)使(shi)用(yong)(yong)10mm以(yi)(yi)上的(de)(de)網(wang)眼為好(hao)。 四(si)、清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)液溫度的(de)(de)選(xuan)擇(ze) 水(shui)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)液最(zui)適宜(yi)的(de)(de)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)溫度為40-60℃,尤其(qi)在(zai)(zai)天冷(leng)時(shi)(shi)若清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)液溫度低(di)空化(hua)效(xiao)(xiao)應(ying)差,清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)效(xiao)(xiao)果(guo)也(ye)(ye)差。因此有部分清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)機在(zai)(zai)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)缸外邊繞上加熱(re)電熱(re)絲進(jin)行溫度控制,當溫度升(sheng)高后空化(hua)易發生(sheng),所(suo)以(yi)(yi)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)...
