一(yi)(yi)、功(gong)(gong)率(lv)(lv)的(de)(de)選(xuan)擇(ze)(ze) 超(chao)(chao)聲波清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)效(xiao)果(guo)(guo)(guo)不一(yi)(yi)定(ding)與(yu)(功(gong)(gong)率(lv)(lv)×清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)時(shi)(shi)(shi)(shi)(shi)(shi)間(jian)(jian)(jian))成正(zheng)比,有(you)時(shi)(shi)(shi)(shi)(shi)(shi)用(yong)(yong)小功(gong)(gong)率(lv)(lv),花費很長時(shi)(shi)(shi)(shi)(shi)(shi)間(jian)(jian)(jian)也沒(mei)有(you)清(qing)(qing)(qing)(qing)(qing)除污垢(gou)。而如果(guo)(guo)(guo)功(gong)(gong)率(lv)(lv)達到(dao)一(yi)(yi)定(ding)數值,有(you)時(shi)(shi)(shi)(shi)(shi)(shi)很快(kuai)便將(jiang)污垢(gou)去除。若(ruo)選(xuan)擇(ze)(ze)功(gong)(gong)率(lv)(lv)太大(da)(da),空(kong)(kong)化強度(du)(du)將(jiang)大(da)(da)大(da)(da)增加,清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)效(xiao)果(guo)(guo)(guo)是提高了,但這時(shi)(shi)(shi)(shi)(shi)(shi)使(shi)較精密(mi)的(de)(de)零(ling)件也產生(sheng)蝕點,得不償失,而且清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)缸底部振(zhen)動板處(chu)空(kong)(kong)化嚴重,水(shui)點腐蝕也增大(da)(da),在(zai)采(cai)用(yong)(yong)三氯(lv)乙烯等有(you)機溶劑時(shi)(shi)(shi)(shi)(shi)(shi),基(ji)本上沒(mei)有(you)問(wen)題,但采(cai)用(yong)(yong)水(shui)或水(shui)溶性(xing)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)液時(shi)(shi)(shi)(shi)(shi)(shi),易于(yu)受(shou)到(dao)水(shui)點腐蝕,如果(guo)(guo)(guo)振(zhen)動板表面已受(shou)到(dao)傷(shang)痕,強功(gong)(gong)率(lv)(lv)下水(shui)底產生(sheng)空(kong)(kong)化腐蝕更(geng)嚴重,因(yin)此(ci)要(yao)(yao)按實際使(shi)用(yong)(yong)情(qing)況選(xuan)擇(ze)(ze)超(chao)(chao)聲功(gong)(gong)率(lv)(lv)。 二、頻(pin)率(lv)(lv)的(de)(de)選(xuan)擇(ze)(ze) 超(chao)(chao)聲清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)頻(pin)率(lv)(lv)從28kHz到(dao)120kHz之間(jian)(jian)(jian),在(zai)使(shi)用(yong)(yong)水(shui)或水(shui)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)劑時(shi)(shi)(shi)(shi)(shi)(shi)由空(kong)(kong)穴(xue)作用(yong)(yong)引起(qi)的(de)(de)物(wu)(wu)理清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)力顯然對(dui)低頻(pin)有(you)利,一(yi)(yi)般(ban)使(shi)用(yong)(yong)28-40kHz左右。對(dui)小間(jian)(jian)(jian)隙(xi)、狹縫、深孔的(de)(de)零(ling)件清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi),用(yong)(yong)高頻(pin)(一(yi)(yi)般(ban)40kHz以上)較好(hao),甚(shen)至幾百kHz。對(dui)鐘表零(ling)件清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)時(shi)(shi)(shi)(shi)(shi)(shi),用(yong)(yong)400kHz。若(ruo)用(yong)(yong)寬帶調頻(pin)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi),效(xiao)果(guo)(guo)(guo)更(geng)良(liang)好(hao)。 三、清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)籃(lan)的(de)(de)使(shi)用(yong)(yong) 在(zai)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)小零(ling)件物(wu)(wu)品時(shi)(shi)(shi)(shi)(shi)(shi),常使(shi)用(yong)(yong)網(wang)籃(lan),由于(yu)網(wang)眼要(yao)(yao)引起(qi)超(chao)(chao)聲衰減(jian),要(yao)(yao)特別引起(qi)注意。當(dang)頻(pin)率(lv)(lv)為28khz時(shi)(shi)(shi)(shi)(shi)(shi)使(shi)用(yong)(yong)10mm以上的(de)(de)網(wang)眼為好(hao)。 四、清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)液溫(wen)度(du)(du)的(de)(de)選(xuan)擇(ze)(ze) 水(shui)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)液最適宜的(de)(de)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)溫(wen)度(du)(du)為40-60℃,尤其在(zai)天冷時(shi)(shi)(shi)(shi)(shi)(shi)若(ruo)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)液溫(wen)度(du)(du)低空(kong)(kong)化效(xiao)應差(cha),清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)效(xiao)果(guo)(guo)(guo)也差(cha)。因(yin)此(ci)有(you)部分清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)機在(zai)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)缸外邊繞上加熱電(dian)熱絲(si)進行溫(wen)度(du)(du)控制,當(dang)溫(wen)度(du)(du)升高后空(kong)(kong)化易發生(sheng),所以清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)...
