一(yi)、功(gong)(gong)率(lv)(lv)的(de)選(xuan)擇(ze)(ze) 超聲(sheng)波清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)效(xiao)果(guo)(guo)不一(yi)定(ding)與(功(gong)(gong)率(lv)(lv)×清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)時(shi)(shi)間(jian))成正比,有(you)(you)時(shi)(shi)用(yong)(yong)(yong)小功(gong)(gong)率(lv)(lv),花費很(hen)長時(shi)(shi)間(jian)也沒(mei)有(you)(you)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)除污垢。而如果(guo)(guo)功(gong)(gong)率(lv)(lv)達到一(yi)定(ding)數(shu)值(zhi),有(you)(you)時(shi)(shi)很(hen)快便將(jiang)污垢去除。若選(xuan)擇(ze)(ze)功(gong)(gong)率(lv)(lv)太大(da),空(kong)化(hua)(hua)強(qiang)度(du)將(jiang)大(da)大(da)增(zeng)加,清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)效(xiao)果(guo)(guo)是提高(gao)了,但這時(shi)(shi)使(shi)(shi)較(jiao)精密(mi)的(de)零件也產生蝕(shi)點(dian)(dian),得不償失,而且清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)缸底(di)部(bu)振(zhen)(zhen)動板處空(kong)化(hua)(hua)嚴重(zhong),水(shui)(shui)(shui)(shui)點(dian)(dian)腐蝕(shi)也增(zeng)大(da),在采用(yong)(yong)(yong)三氯乙(yi)烯等有(you)(you)機溶劑時(shi)(shi),基(ji)本上沒(mei)有(you)(you)問題,但采用(yong)(yong)(yong)水(shui)(shui)(shui)(shui)或(huo)水(shui)(shui)(shui)(shui)溶性清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)液(ye)時(shi)(shi),易(yi)于受到水(shui)(shui)(shui)(shui)點(dian)(dian)腐蝕(shi),如果(guo)(guo)振(zhen)(zhen)動板表面已受到傷痕,強(qiang)功(gong)(gong)率(lv)(lv)下水(shui)(shui)(shui)(shui)底(di)產生空(kong)化(hua)(hua)腐蝕(shi)更(geng)嚴重(zhong),因此要(yao)按實際使(shi)(shi)用(yong)(yong)(yong)情況選(xuan)擇(ze)(ze)超聲(sheng)功(gong)(gong)率(lv)(lv)。 二、頻(pin)率(lv)(lv)的(de)選(xuan)擇(ze)(ze) 超聲(sheng)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)頻(pin)率(lv)(lv)從(cong)28kHz到120kHz之間(jian),在使(shi)(shi)用(yong)(yong)(yong)水(shui)(shui)(shui)(shui)或(huo)水(shui)(shui)(shui)(shui)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)劑時(shi)(shi)由(you)空(kong)穴作用(yong)(yong)(yong)引(yin)起的(de)物理清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)力顯然(ran)對(dui)(dui)(dui)低(di)頻(pin)有(you)(you)利,一(yi)般使(shi)(shi)用(yong)(yong)(yong)28-40kHz左右(you)。對(dui)(dui)(dui)小間(jian)隙、狹縫、深孔的(de)零件清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi),用(yong)(yong)(yong)高(gao)頻(pin)(一(yi)般40kHz以(yi)上)較(jiao)好(hao),甚至幾(ji)百kHz。對(dui)(dui)(dui)鐘表零件清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)時(shi)(shi),用(yong)(yong)(yong)400kHz。若用(yong)(yong)(yong)寬帶調頻(pin)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi),效(xiao)果(guo)(guo)更(geng)良(liang)好(hao)。 三、清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)籃(lan)的(de)使(shi)(shi)用(yong)(yong)(yong) 在清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)小零件物品時(shi)(shi),常(chang)使(shi)(shi)用(yong)(yong)(yong)網籃(lan),由(you)于網眼要(yao)引(yin)起超聲(sheng)衰減,要(yao)特別(bie)引(yin)起注意。當(dang)頻(pin)率(lv)(lv)為(wei)28khz時(shi)(shi)使(shi)(shi)用(yong)(yong)(yong)10mm以(yi)上的(de)網眼為(wei)好(hao)。 四、清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)液(ye)溫(wen)(wen)(wen)(wen)度(du)的(de)選(xuan)擇(ze)(ze) 水(shui)(shui)(shui)(shui)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)液(ye)最(zui)適宜的(de)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)溫(wen)(wen)(wen)(wen)度(du)為(wei)40-60℃,尤其在天冷時(shi)(shi)若清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)液(ye)溫(wen)(wen)(wen)(wen)度(du)低(di)空(kong)化(hua)(hua)效(xiao)應差,清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)效(xiao)果(guo)(guo)也差。因此有(you)(you)部(bu)分清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)機在清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)缸外邊繞上加熱(re)電(dian)熱(re)絲(si)進行溫(wen)(wen)(wen)(wen)度(du)控制(zhi),當(dang)溫(wen)(wen)(wen)(wen)度(du)升高(gao)后空(kong)化(hua)(hua)易(yi)發生,所以(yi)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)...
