一(yi)(yi)、功率的(de)(de)選擇(ze)(ze) 超聲波(bo)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)效(xiao)(xiao)果(guo)(guo)(guo)不(bu)一(yi)(yi)定與(功率×清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)時(shi)間(jian))成(cheng)正(zheng)比,有(you)時(shi)用(yong)小(xiao)(xiao)功率,花費很長時(shi)間(jian)也(ye)(ye)沒有(you)清(qing)(qing)(qing)(qing)除污垢。而(er)如果(guo)(guo)(guo)功率達到(dao)一(yi)(yi)定數值,有(you)時(shi)很快便將污垢去除。若(ruo)選擇(ze)(ze)功率太(tai)大,空化(hua)(hua)強(qiang)度將大大增加,清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)效(xiao)(xiao)果(guo)(guo)(guo)是(shi)提高(gao)了,但(dan)這時(shi)使(shi)較(jiao)精密的(de)(de)零(ling)(ling)件也(ye)(ye)產(chan)生(sheng)蝕(shi)點(dian)(dian),得不(bu)償失,而(er)且(qie)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)缸底部振動(dong)板(ban)處空化(hua)(hua)嚴重,水(shui)(shui)(shui)(shui)點(dian)(dian)腐(fu)蝕(shi)也(ye)(ye)增大,在(zai)采(cai)用(yong)三氯(lv)乙烯(xi)等(deng)有(you)機(ji)溶劑(ji)時(shi),基本上沒有(you)問題,但(dan)采(cai)用(yong)水(shui)(shui)(shui)(shui)或(huo)水(shui)(shui)(shui)(shui)溶性清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)液(ye)時(shi),易(yi)于(yu)受(shou)到(dao)水(shui)(shui)(shui)(shui)點(dian)(dian)腐(fu)蝕(shi),如果(guo)(guo)(guo)振動(dong)板(ban)表(biao)面已受(shou)到(dao)傷痕,強(qiang)功率下水(shui)(shui)(shui)(shui)底產(chan)生(sheng)空化(hua)(hua)腐(fu)蝕(shi)更嚴重,因此(ci)要(yao)(yao)按實際使(shi)用(yong)情況選擇(ze)(ze)超聲功率。 二、頻(pin)率的(de)(de)選擇(ze)(ze) 超聲清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)頻(pin)率從28kHz到(dao)120kHz之間(jian),在(zai)使(shi)用(yong)水(shui)(shui)(shui)(shui)或(huo)水(shui)(shui)(shui)(shui)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)劑(ji)時(shi)由空穴作用(yong)引起的(de)(de)物(wu)理清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)力(li)顯然對(dui)低頻(pin)有(you)利(li),一(yi)(yi)般使(shi)用(yong)28-40kHz左右。對(dui)小(xiao)(xiao)間(jian)隙(xi)、狹縫、深孔的(de)(de)零(ling)(ling)件清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi),用(yong)高(gao)頻(pin)(一(yi)(yi)般40kHz以上)較(jiao)好,甚(shen)至幾百kHz。對(dui)鐘表(biao)零(ling)(ling)件清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)時(shi),用(yong)400kHz。若(ruo)用(yong)寬帶調頻(pin)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi),效(xiao)(xiao)果(guo)(guo)(guo)更良(liang)好。 三、清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)籃的(de)(de)使(shi)用(yong) 在(zai)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)小(xiao)(xiao)零(ling)(ling)件物(wu)品時(shi),常使(shi)用(yong)網籃,由于(yu)網眼(yan)要(yao)(yao)引起超聲衰減,要(yao)(yao)特別引起注意。當頻(pin)率為28khz時(shi)使(shi)用(yong)10mm以上的(de)(de)網眼(yan)為好。 四、清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)液(ye)溫度的(de)(de)選擇(ze)(ze) 水(shui)(shui)(shui)(shui)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)液(ye)最適宜的(de)(de)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)溫度為40-60℃,尤(you)其在(zai)天冷時(shi)若(ruo)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)液(ye)溫度低空化(hua)(hua)效(xiao)(xiao)應差(cha),清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)效(xiao)(xiao)果(guo)(guo)(guo)也(ye)(ye)差(cha)。因此(ci)有(you)部分(fen)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)機(ji)在(zai)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)缸外邊繞上加熱電熱絲進行(xing)溫度控制,當溫度升(sheng)高(gao)后(hou)空化(hua)(hua)易(yi)發生(sheng),所以清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)(xi)...
