一、功(gong)(gong)率(lv)的(de)(de)選擇(ze) 超(chao)聲波清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效果(guo)(guo)不一定與(yu)(功(gong)(gong)率(lv)×清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)時(shi)間)成正(zheng)比,有(you)(you)(you)時(shi)用(yong)(yong)(yong)小(xiao)(xiao)功(gong)(gong)率(lv),花費(fei)很長時(shi)間也沒(mei)有(you)(you)(you)清(qing)(qing)(qing)除污垢(gou)。而如(ru)果(guo)(guo)功(gong)(gong)率(lv)達(da)到(dao)一定數(shu)值,有(you)(you)(you)時(shi)很快便將污垢(gou)去(qu)除。若選擇(ze)功(gong)(gong)率(lv)太大(da)(da),空化(hua)強度(du)將大(da)(da)大(da)(da)增(zeng)加,清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效果(guo)(guo)是提(ti)高了(le),但這時(shi)使(shi)(shi)較精(jing)密的(de)(de)零件也產生蝕(shi)(shi)點,得不償失,而且清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)缸(gang)底部振(zhen)動板處(chu)空化(hua)嚴重,水點腐蝕(shi)(shi)也增(zeng)大(da)(da),在采(cai)(cai)用(yong)(yong)(yong)三氯乙烯(xi)等有(you)(you)(you)機溶(rong)劑時(shi),基本上沒(mei)有(you)(you)(you)問(wen)題,但采(cai)(cai)用(yong)(yong)(yong)水或(huo)水溶(rong)性清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)(ye)時(shi),易(yi)于(yu)受(shou)到(dao)水點腐蝕(shi)(shi),如(ru)果(guo)(guo)振(zhen)動板表面已(yi)受(shou)到(dao)傷痕,強功(gong)(gong)率(lv)下水底產生空化(hua)腐蝕(shi)(shi)更嚴重,因此(ci)要(yao)按實際使(shi)(shi)用(yong)(yong)(yong)情況選擇(ze)超(chao)聲功(gong)(gong)率(lv)。 二、頻(pin)率(lv)的(de)(de)選擇(ze) 超(chao)聲清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)頻(pin)率(lv)從28kHz到(dao)120kHz之間,在使(shi)(shi)用(yong)(yong)(yong)水或(huo)水清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)劑時(shi)由空穴(xue)作用(yong)(yong)(yong)引起(qi)的(de)(de)物理清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)力顯然對(dui)(dui)(dui)低(di)頻(pin)有(you)(you)(you)利,一般使(shi)(shi)用(yong)(yong)(yong)28-40kHz左右。對(dui)(dui)(dui)小(xiao)(xiao)間隙(xi)、狹縫(feng)、深(shen)孔(kong)的(de)(de)零件清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi),用(yong)(yong)(yong)高頻(pin)(一般40kHz以上)較好,甚(shen)至幾百kHz。對(dui)(dui)(dui)鐘表零件清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)時(shi),用(yong)(yong)(yong)400kHz。若用(yong)(yong)(yong)寬帶調(diao)頻(pin)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi),效果(guo)(guo)更良好。 三、清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)籃的(de)(de)使(shi)(shi)用(yong)(yong)(yong) 在清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)小(xiao)(xiao)零件物品時(shi),常使(shi)(shi)用(yong)(yong)(yong)網(wang)籃,由于(yu)網(wang)眼(yan)要(yao)引起(qi)超(chao)聲衰(shuai)減(jian),要(yao)特別(bie)引起(qi)注(zhu)意。當頻(pin)率(lv)為28khz時(shi)使(shi)(shi)用(yong)(yong)(yong)10mm以上的(de)(de)網(wang)眼(yan)為好。 四(si)、清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)(ye)溫(wen)(wen)度(du)的(de)(de)選擇(ze) 水清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)(ye)最適宜的(de)(de)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)溫(wen)(wen)度(du)為40-60℃,尤(you)其在天(tian)冷時(shi)若清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)(ye)溫(wen)(wen)度(du)低(di)空化(hua)效應差,清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效果(guo)(guo)也差。因此(ci)有(you)(you)(you)部分清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)機在清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)缸(gang)外邊(bian)繞上加熱(re)電熱(re)絲進行(xing)溫(wen)(wen)度(du)控制,當溫(wen)(wen)度(du)升高后空化(hua)易(yi)發生,所以清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)...
