一、功(gong)(gong)(gong)率(lv)的(de)選(xuan)擇(ze) 超(chao)聲(sheng)(sheng)波清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效(xiao)果不(bu)一定與(功(gong)(gong)(gong)率(lv)×清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)時(shi)(shi)(shi)(shi)(shi)間)成正比,有(you)(you)時(shi)(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)小功(gong)(gong)(gong)率(lv),花(hua)費很長時(shi)(shi)(shi)(shi)(shi)間也(ye)沒(mei)有(you)(you)清(qing)(qing)(qing)除污垢。而如(ru)果功(gong)(gong)(gong)率(lv)達到(dao)(dao)一定數值,有(you)(you)時(shi)(shi)(shi)(shi)(shi)很快(kuai)便將污垢去除。若(ruo)選(xuan)擇(ze)功(gong)(gong)(gong)率(lv)太大(da),空化強(qiang)度將大(da)大(da)增加,清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效(xiao)果是提高(gao)(gao)了,但這時(shi)(shi)(shi)(shi)(shi)使(shi)(shi)(shi)較(jiao)精密(mi)的(de)零(ling)件(jian)(jian)也(ye)產生蝕點(dian),得(de)不(bu)償(chang)失(shi),而且(qie)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)缸(gang)底部振(zhen)(zhen)動板(ban)(ban)處空化嚴重(zhong),水(shui)點(dian)腐蝕也(ye)增大(da),在(zai)采用(yong)(yong)(yong)(yong)三氯乙烯等(deng)有(you)(you)機溶劑時(shi)(shi)(shi)(shi)(shi),基本上(shang)(shang)(shang)沒(mei)有(you)(you)問題,但采用(yong)(yong)(yong)(yong)水(shui)或水(shui)溶性清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)時(shi)(shi)(shi)(shi)(shi),易于(yu)受到(dao)(dao)水(shui)點(dian)腐蝕,如(ru)果振(zhen)(zhen)動板(ban)(ban)表面已受到(dao)(dao)傷(shang)痕,強(qiang)功(gong)(gong)(gong)率(lv)下水(shui)底產生空化腐蝕更嚴重(zhong),因此要按實(shi)際使(shi)(shi)(shi)用(yong)(yong)(yong)(yong)情況選(xuan)擇(ze)超(chao)聲(sheng)(sheng)功(gong)(gong)(gong)率(lv)。 二、頻(pin)率(lv)的(de)選(xuan)擇(ze) 超(chao)聲(sheng)(sheng)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)頻(pin)率(lv)從28kHz到(dao)(dao)120kHz之間,在(zai)使(shi)(shi)(shi)用(yong)(yong)(yong)(yong)水(shui)或水(shui)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)劑時(shi)(shi)(shi)(shi)(shi)由空穴作用(yong)(yong)(yong)(yong)引起的(de)物理清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)力顯然(ran)對(dui)低頻(pin)有(you)(you)利,一般使(shi)(shi)(shi)用(yong)(yong)(yong)(yong)28-40kHz左右。對(dui)小間隙(xi)、狹縫(feng)、深孔的(de)零(ling)件(jian)(jian)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi),用(yong)(yong)(yong)(yong)高(gao)(gao)頻(pin)(一般40kHz以上(shang)(shang)(shang))較(jiao)好(hao)(hao),甚(shen)至幾百(bai)kHz。對(dui)鐘表零(ling)件(jian)(jian)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)時(shi)(shi)(shi)(shi)(shi),用(yong)(yong)(yong)(yong)400kHz。若(ruo)用(yong)(yong)(yong)(yong)寬帶調頻(pin)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi),效(xiao)果更良好(hao)(hao)。 三、清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)籃的(de)使(shi)(shi)(shi)用(yong)(yong)(yong)(yong) 在(zai)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)小零(ling)件(jian)(jian)物品時(shi)(shi)(shi)(shi)(shi),常(chang)使(shi)(shi)(shi)用(yong)(yong)(yong)(yong)網(wang)(wang)籃,由于(yu)網(wang)(wang)眼(yan)要引起超(chao)聲(sheng)(sheng)衰減(jian),要特(te)別引起注意。當頻(pin)率(lv)為(wei)28khz時(shi)(shi)(shi)(shi)(shi)使(shi)(shi)(shi)用(yong)(yong)(yong)(yong)10mm以上(shang)(shang)(shang)的(de)網(wang)(wang)眼(yan)為(wei)好(hao)(hao)。 四、清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)溫(wen)(wen)度的(de)選(xuan)擇(ze) 水(shui)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)最(zui)適宜的(de)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)溫(wen)(wen)度為(wei)40-60℃,尤其在(zai)天冷(leng)時(shi)(shi)(shi)(shi)(shi)若(ruo)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)溫(wen)(wen)度低空化效(xiao)應差,清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效(xiao)果也(ye)差。因此有(you)(you)部分清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)機在(zai)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)缸(gang)外(wai)邊繞(rao)上(shang)(shang)(shang)加熱電熱絲(si)進行溫(wen)(wen)度控制,當溫(wen)(wen)度升(sheng)高(gao)(gao)后空化易發生,所以清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)...
