一、功(gong)(gong)率的選(xuan)擇(ze) 超(chao)聲波清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效果(guo)(guo)不(bu)一定與(功(gong)(gong)率×清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)時(shi)間(jian))成正比(bi),有(you)(you)(you)時(shi)用(yong)小(xiao)(xiao)功(gong)(gong)率,花費很長(chang)時(shi)間(jian)也(ye)沒(mei)有(you)(you)(you)清(qing)(qing)(qing)(qing)(qing)(qing)除污(wu)垢。而如(ru)果(guo)(guo)功(gong)(gong)率達到(dao)一定數值,有(you)(you)(you)時(shi)很快(kuai)便(bian)將污(wu)垢去除。若(ruo)(ruo)選(xuan)擇(ze)功(gong)(gong)率太大(da),空(kong)化(hua)強(qiang)度(du)將大(da)大(da)增(zeng)加,清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效果(guo)(guo)是提高(gao)了,但這時(shi)使(shi)(shi)較精密的零(ling)(ling)件(jian)也(ye)產生(sheng)(sheng)(sheng)蝕(shi)點(dian),得不(bu)償(chang)失(shi),而且(qie)清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)缸底(di)部振動板處空(kong)化(hua)嚴重(zhong),水(shui)(shui)(shui)點(dian)腐蝕(shi)也(ye)增(zeng)大(da),在采用(yong)三氯乙烯等有(you)(you)(you)機(ji)(ji)溶劑時(shi),基本上(shang)(shang)沒(mei)有(you)(you)(you)問題,但采用(yong)水(shui)(shui)(shui)或水(shui)(shui)(shui)溶性清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液時(shi),易于受(shou)到(dao)水(shui)(shui)(shui)點(dian)腐蝕(shi),如(ru)果(guo)(guo)振動板表(biao)面(mian)已受(shou)到(dao)傷痕,強(qiang)功(gong)(gong)率下水(shui)(shui)(shui)底(di)產生(sheng)(sheng)(sheng)空(kong)化(hua)腐蝕(shi)更(geng)嚴重(zhong),因(yin)此要(yao)按(an)實際使(shi)(shi)用(yong)情況選(xuan)擇(ze)超(chao)聲功(gong)(gong)率。 二、頻(pin)(pin)率的選(xuan)擇(ze) 超(chao)聲清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)頻(pin)(pin)率從(cong)28kHz到(dao)120kHz之間(jian),在使(shi)(shi)用(yong)水(shui)(shui)(shui)或水(shui)(shui)(shui)清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)劑時(shi)由空(kong)穴作用(yong)引(yin)起(qi)的物理(li)清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)力(li)顯然對低頻(pin)(pin)有(you)(you)(you)利,一般使(shi)(shi)用(yong)28-40kHz左(zuo)右。對小(xiao)(xiao)間(jian)隙、狹縫、深孔的零(ling)(ling)件(jian)清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi),用(yong)高(gao)頻(pin)(pin)(一般40kHz以(yi)上(shang)(shang))較好,甚至(zhi)幾百kHz。對鐘表(biao)零(ling)(ling)件(jian)清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)時(shi),用(yong)400kHz。若(ruo)(ruo)用(yong)寬(kuan)帶調頻(pin)(pin)清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi),效果(guo)(guo)更(geng)良好。 三、清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)籃(lan)的使(shi)(shi)用(yong) 在清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)小(xiao)(xiao)零(ling)(ling)件(jian)物品時(shi),常使(shi)(shi)用(yong)網(wang)籃(lan),由于網(wang)眼要(yao)引(yin)起(qi)超(chao)聲衰減,要(yao)特別引(yin)起(qi)注意。當頻(pin)(pin)率為28khz時(shi)使(shi)(shi)用(yong)10mm以(yi)上(shang)(shang)的網(wang)眼為好。 四、清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液溫(wen)度(du)的選(xuan)擇(ze) 水(shui)(shui)(shui)清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液最適(shi)宜的清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)溫(wen)度(du)為40-60℃,尤其在天冷時(shi)若(ruo)(ruo)清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液溫(wen)度(du)低空(kong)化(hua)效應(ying)差(cha),清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效果(guo)(guo)也(ye)差(cha)。因(yin)此有(you)(you)(you)部分(fen)清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)機(ji)(ji)在清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)缸外邊繞(rao)上(shang)(shang)加熱電(dian)熱絲進行溫(wen)度(du)控制,當溫(wen)度(du)升高(gao)后空(kong)化(hua)易發(fa)生(sheng)(sheng)(sheng),所以(yi)清(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)...
