一、功(gong)(gong)(gong)率(lv)(lv)(lv)的(de)(de)(de)(de)(de)選(xuan)(xuan)擇(ze) 超聲(sheng)波清(qing)(qing)洗(xi)(xi)效果(guo)(guo)(guo)不一定與(功(gong)(gong)(gong)率(lv)(lv)(lv)×清(qing)(qing)洗(xi)(xi)時(shi)(shi)間(jian))成正(zheng)比,有(you)時(shi)(shi)用(yong)(yong)小(xiao)功(gong)(gong)(gong)率(lv)(lv)(lv),花費很(hen)長時(shi)(shi)間(jian)也(ye)沒(mei)有(you)清(qing)(qing)除污垢(gou)。而如果(guo)(guo)(guo)功(gong)(gong)(gong)率(lv)(lv)(lv)達到(dao)一定數值,有(you)時(shi)(shi)很(hen)快便(bian)將(jiang)污垢(gou)去除。若(ruo)選(xuan)(xuan)擇(ze)功(gong)(gong)(gong)率(lv)(lv)(lv)太大(da)(da),空(kong)(kong)(kong)化(hua)(hua)強(qiang)(qiang)度(du)將(jiang)大(da)(da)大(da)(da)增加,清(qing)(qing)洗(xi)(xi)效果(guo)(guo)(guo)是提(ti)高了,但這時(shi)(shi)使(shi)較精密的(de)(de)(de)(de)(de)零(ling)件也(ye)產生(sheng)(sheng)蝕(shi)點(dian),得不償失,而且清(qing)(qing)洗(xi)(xi)缸底(di)部振(zhen)(zhen)動(dong)(dong)板處空(kong)(kong)(kong)化(hua)(hua)嚴(yan)重(zhong)(zhong),水(shui)(shui)(shui)點(dian)腐蝕(shi)也(ye)增大(da)(da),在(zai)采用(yong)(yong)三氯乙(yi)烯等有(you)機(ji)溶(rong)劑時(shi)(shi),基本上沒(mei)有(you)問題,但采用(yong)(yong)水(shui)(shui)(shui)或水(shui)(shui)(shui)溶(rong)性清(qing)(qing)洗(xi)(xi)液(ye)(ye)時(shi)(shi),易于受(shou)到(dao)水(shui)(shui)(shui)點(dian)腐蝕(shi),如果(guo)(guo)(guo)振(zhen)(zhen)動(dong)(dong)板表面已(yi)受(shou)到(dao)傷痕,強(qiang)(qiang)功(gong)(gong)(gong)率(lv)(lv)(lv)下水(shui)(shui)(shui)底(di)產生(sheng)(sheng)空(kong)(kong)(kong)化(hua)(hua)腐蝕(shi)更(geng)(geng)嚴(yan)重(zhong)(zhong),因(yin)此要(yao)按實際使(shi)用(yong)(yong)情況選(xuan)(xuan)擇(ze)超聲(sheng)功(gong)(gong)(gong)率(lv)(lv)(lv)。 二、頻率(lv)(lv)(lv)的(de)(de)(de)(de)(de)選(xuan)(xuan)擇(ze) 超聲(sheng)清(qing)(qing)洗(xi)(xi)頻率(lv)(lv)(lv)從(cong)28kHz到(dao)120kHz之間(jian),在(zai)使(shi)用(yong)(yong)水(shui)(shui)(shui)或水(shui)(shui)(shui)清(qing)(qing)洗(xi)(xi)劑時(shi)(shi)由(you)空(kong)(kong)(kong)穴作用(yong)(yong)引(yin)(yin)起的(de)(de)(de)(de)(de)物(wu)(wu)理清(qing)(qing)洗(xi)(xi)力(li)顯然(ran)對低(di)頻有(you)利,一般(ban)使(shi)用(yong)(yong)28-40kHz左右。對小(xiao)間(jian)隙、狹縫、深孔的(de)(de)(de)(de)(de)零(ling)件清(qing)(qing)洗(xi)(xi),用(yong)(yong)高頻(一般(ban)40kHz以上)較好,甚至幾百kHz。對鐘表零(ling)件清(qing)(qing)洗(xi)(xi)時(shi)(shi),用(yong)(yong)400kHz。若(ruo)用(yong)(yong)寬帶調頻清(qing)(qing)洗(xi)(xi),效果(guo)(guo)(guo)更(geng)(geng)良好。 三、清(qing)(qing)洗(xi)(xi)籃的(de)(de)(de)(de)(de)使(shi)用(yong)(yong) 在(zai)清(qing)(qing)洗(xi)(xi)小(xiao)零(ling)件物(wu)(wu)品時(shi)(shi),常使(shi)用(yong)(yong)網(wang)籃,由(you)于網(wang)眼要(yao)引(yin)(yin)起超聲(sheng)衰減,要(yao)特(te)別引(yin)(yin)起注意。當頻率(lv)(lv)(lv)為(wei)28khz時(shi)(shi)使(shi)用(yong)(yong)10mm以上的(de)(de)(de)(de)(de)網(wang)眼為(wei)好。 四、清(qing)(qing)洗(xi)(xi)液(ye)(ye)溫度(du)的(de)(de)(de)(de)(de)選(xuan)(xuan)擇(ze) 水(shui)(shui)(shui)清(qing)(qing)洗(xi)(xi)液(ye)(ye)最(zui)適宜的(de)(de)(de)(de)(de)清(qing)(qing)洗(xi)(xi)溫度(du)為(wei)40-60℃,尤其在(zai)天冷時(shi)(shi)若(ruo)清(qing)(qing)洗(xi)(xi)液(ye)(ye)溫度(du)低(di)空(kong)(kong)(kong)化(hua)(hua)效應差,清(qing)(qing)洗(xi)(xi)效果(guo)(guo)(guo)也(ye)差。因(yin)此有(you)部分清(qing)(qing)洗(xi)(xi)機(ji)在(zai)清(qing)(qing)洗(xi)(xi)缸外(wai)邊(bian)繞(rao)上加熱(re)電(dian)熱(re)絲進行(xing)溫度(du)控制,當溫度(du)升高后空(kong)(kong)(kong)化(hua)(hua)易發生(sheng)(sheng),所以清(qing)(qing)洗(xi)(xi)...
