一(yi)、功率(lv)的(de)(de)選(xuan)擇(ze) 超聲波清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效(xiao)果不一(yi)定與(功率(lv)×清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)時(shi)間(jian)(jian)(jian))成正比,有(you)時(shi)用(yong)(yong)小(xiao)功率(lv),花費很(hen)長時(shi)間(jian)(jian)(jian)也沒有(you)清(qing)(qing)(qing)(qing)(qing)除污垢。而如(ru)果功率(lv)達(da)到(dao)一(yi)定數值,有(you)時(shi)很(hen)快便將污垢去除。若(ruo)(ruo)選(xuan)擇(ze)功率(lv)太大(da),空(kong)(kong)(kong)化強度將大(da)大(da)增加,清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效(xiao)果是(shi)提(ti)高(gao)(gao)了,但這時(shi)使(shi)較精(jing)密的(de)(de)零件(jian)也產生蝕(shi)(shi)點,得不償失,而且清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)缸(gang)底部(bu)振(zhen)動板處(chu)空(kong)(kong)(kong)化嚴重,水(shui)(shui)(shui)點腐(fu)蝕(shi)(shi)也增大(da),在(zai)(zai)采(cai)用(yong)(yong)三(san)氯乙烯等有(you)機溶劑時(shi),基本(ben)上沒有(you)問題,但采(cai)用(yong)(yong)水(shui)(shui)(shui)或水(shui)(shui)(shui)溶性清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液時(shi),易(yi)于受(shou)到(dao)水(shui)(shui)(shui)點腐(fu)蝕(shi)(shi),如(ru)果振(zhen)動板表面已(yi)受(shou)到(dao)傷痕,強功率(lv)下(xia)水(shui)(shui)(shui)底產生空(kong)(kong)(kong)化腐(fu)蝕(shi)(shi)更嚴重,因此(ci)要按實(shi)際使(shi)用(yong)(yong)情況(kuang)選(xuan)擇(ze)超聲功率(lv)。 二、頻(pin)(pin)(pin)(pin)(pin)(pin)率(lv)的(de)(de)選(xuan)擇(ze) 超聲清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)頻(pin)(pin)(pin)(pin)(pin)(pin)率(lv)從28kHz到(dao)120kHz之間(jian)(jian)(jian),在(zai)(zai)使(shi)用(yong)(yong)水(shui)(shui)(shui)或水(shui)(shui)(shui)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)劑時(shi)由(you)空(kong)(kong)(kong)穴作用(yong)(yong)引(yin)起的(de)(de)物(wu)理清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)力顯然對(dui)低頻(pin)(pin)(pin)(pin)(pin)(pin)有(you)利,一(yi)般使(shi)用(yong)(yong)28-40kHz左右。對(dui)小(xiao)間(jian)(jian)(jian)隙、狹縫、深孔(kong)的(de)(de)零件(jian)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi),用(yong)(yong)高(gao)(gao)頻(pin)(pin)(pin)(pin)(pin)(pin)(一(yi)般40kHz以上)較好,甚(shen)至(zhi)幾百kHz。對(dui)鐘(zhong)表零件(jian)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)時(shi),用(yong)(yong)400kHz。若(ruo)(ruo)用(yong)(yong)寬帶調頻(pin)(pin)(pin)(pin)(pin)(pin)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi),效(xiao)果更良好。 三(san)、清(qing)(qing)(qing)(qing)(qing)洗(xi)(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)(xi)小(xiao)零件(jian)物(wu)品時(shi),常使(shi)用(yong)(yong)網(wang)(wang)籃,由(you)于網(wang)(wang)眼(yan)要引(yin)起超聲衰減,要特別引(yin)起注意。當(dang)頻(pin)(pin)(pin)(pin)(pin)(pin)率(lv)為(wei)(wei)28khz時(shi)使(shi)用(yong)(yong)10mm以上的(de)(de)網(wang)(wang)眼(yan)為(wei)(wei)好。 四、清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液溫度的(de)(de)選(xuan)擇(ze) 水(shui)(shui)(shui)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液最適(shi)宜的(de)(de)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)溫度為(wei)(wei)40-60℃,尤(you)其在(zai)(zai)天冷(leng)時(shi)若(ruo)(ruo)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液溫度低空(kong)(kong)(kong)化效(xiao)應差,清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效(xiao)果也差。因此(ci)有(you)部(bu)分(fen)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)機在(zai)(zai)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)缸(gang)外(wai)邊繞上加熱(re)電熱(re)絲進行(xing)溫度控制(zhi),當(dang)溫度升高(gao)(gao)后空(kong)(kong)(kong)化易(yi)發生,所以清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)...
