一(yi)、功(gong)(gong)率(lv)的(de)選(xuan)(xuan)擇(ze) 超(chao)聲(sheng)波(bo)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)效果(guo)(guo)不一(yi)定與(功(gong)(gong)率(lv)×清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)時(shi)(shi)間)成正比,有時(shi)(shi)用(yong)(yong)(yong)(yong)(yong)小(xiao)功(gong)(gong)率(lv),花費很(hen)長時(shi)(shi)間也沒有清(qing)(qing)(qing)(qing)(qing)除污(wu)垢(gou)。而如果(guo)(guo)功(gong)(gong)率(lv)達(da)到一(yi)定數(shu)值,有時(shi)(shi)很(hen)快便將(jiang)污(wu)垢(gou)去除。若選(xuan)(xuan)擇(ze)功(gong)(gong)率(lv)太大(da),空(kong)(kong)(kong)(kong)化(hua)(hua)強度將(jiang)大(da)大(da)增加,清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)效果(guo)(guo)是提高了,但(dan)這時(shi)(shi)使較精(jing)密的(de)零(ling)件(jian)也產(chan)生蝕(shi)點(dian),得不償失(shi),而且清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)缸底(di)部(bu)振動板處空(kong)(kong)(kong)(kong)化(hua)(hua)嚴(yan)重,水(shui)(shui)點(dian)腐蝕(shi)也增大(da),在采用(yong)(yong)(yong)(yong)(yong)三氯乙烯(xi)等有機溶劑時(shi)(shi),基(ji)本(ben)上(shang)沒有問題,但(dan)采用(yong)(yong)(yong)(yong)(yong)水(shui)(shui)或水(shui)(shui)溶性(xing)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)液時(shi)(shi),易于受(shou)到水(shui)(shui)點(dian)腐蝕(shi),如果(guo)(guo)振動板表(biao)面已受(shou)到傷(shang)痕,強功(gong)(gong)率(lv)下水(shui)(shui)底(di)產(chan)生空(kong)(kong)(kong)(kong)化(hua)(hua)腐蝕(shi)更嚴(yan)重,因此要(yao)(yao)按實際使用(yong)(yong)(yong)(yong)(yong)情況選(xuan)(xuan)擇(ze)超(chao)聲(sheng)功(gong)(gong)率(lv)。 二、頻率(lv)的(de)選(xuan)(xuan)擇(ze) 超(chao)聲(sheng)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)頻率(lv)從28kHz到120kHz之間,在使用(yong)(yong)(yong)(yong)(yong)水(shui)(shui)或水(shui)(shui)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)劑時(shi)(shi)由(you)空(kong)(kong)(kong)(kong)穴作用(yong)(yong)(yong)(yong)(yong)引(yin)起的(de)物理清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)力顯(xian)然對(dui)低頻有利,一(yi)般(ban)使用(yong)(yong)(yong)(yong)(yong)28-40kHz左右。對(dui)小(xiao)間隙、狹縫、深孔的(de)零(ling)件(jian)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi),用(yong)(yong)(yong)(yong)(yong)高頻(一(yi)般(ban)40kHz以上(shang))較好,甚至幾百kHz。對(dui)鐘表(biao)零(ling)件(jian)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)時(shi)(shi),用(yong)(yong)(yong)(yong)(yong)400kHz。若用(yong)(yong)(yong)(yong)(yong)寬帶(dai)調頻清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi),效果(guo)(guo)更良好。 三、清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)籃的(de)使用(yong)(yong)(yong)(yong)(yong) 在清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)小(xiao)零(ling)件(jian)物品時(shi)(shi),常使用(yong)(yong)(yong)(yong)(yong)網(wang)籃,由(you)于網(wang)眼要(yao)(yao)引(yin)起超(chao)聲(sheng)衰(shuai)減,要(yao)(yao)特別引(yin)起注意。當頻率(lv)為(wei)28khz時(shi)(shi)使用(yong)(yong)(yong)(yong)(yong)10mm以上(shang)的(de)網(wang)眼為(wei)好。 四、清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)液溫(wen)(wen)度的(de)選(xuan)(xuan)擇(ze) 水(shui)(shui)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)液最適(shi)宜的(de)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)溫(wen)(wen)度為(wei)40-60℃,尤其在天冷時(shi)(shi)若清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)液溫(wen)(wen)度低空(kong)(kong)(kong)(kong)化(hua)(hua)效應差,清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)效果(guo)(guo)也差。因此有部(bu)分清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)機在清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)缸外邊(bian)繞上(shang)加熱電熱絲(si)進(jin)行溫(wen)(wen)度控(kong)制,當溫(wen)(wen)度升高后(hou)空(kong)(kong)(kong)(kong)化(hua)(hua)易發生,所以清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)...
