一、功(gong)率(lv)(lv)的(de)選擇(ze)(ze) 超聲(sheng)波清(qing)(qing)洗(xi)(xi)(xi)效(xiao)果(guo)不一定與(功(gong)率(lv)(lv)×清(qing)(qing)洗(xi)(xi)(xi)時(shi)間)成正比,有(you)時(shi)用小(xiao)(xiao)(xiao)功(gong)率(lv)(lv),花費很長(chang)時(shi)間也沒有(you)清(qing)(qing)除污(wu)垢。而(er)(er)如果(guo)功(gong)率(lv)(lv)達(da)到(dao)一定數值,有(you)時(shi)很快便(bian)將(jiang)污(wu)垢去除。若選擇(ze)(ze)功(gong)率(lv)(lv)太大(da),空(kong)化(hua)強度將(jiang)大(da)大(da)增(zeng)加,清(qing)(qing)洗(xi)(xi)(xi)效(xiao)果(guo)是提高了(le),但這時(shi)使較精密的(de)零(ling)件也產生(sheng)蝕(shi)點(dian)(dian),得不償失,而(er)(er)且清(qing)(qing)洗(xi)(xi)(xi)缸底(di)部振動(dong)板處空(kong)化(hua)嚴重(zhong),水(shui)(shui)(shui)(shui)點(dian)(dian)腐(fu)蝕(shi)也增(zeng)大(da),在采用三氯乙烯等有(you)機溶(rong)劑(ji)時(shi),基本上(shang)沒有(you)問題(ti),但采用水(shui)(shui)(shui)(shui)或(huo)水(shui)(shui)(shui)(shui)溶(rong)性清(qing)(qing)洗(xi)(xi)(xi)液時(shi),易于(yu)受到(dao)水(shui)(shui)(shui)(shui)點(dian)(dian)腐(fu)蝕(shi),如果(guo)振動(dong)板表面已受到(dao)傷痕,強功(gong)率(lv)(lv)下水(shui)(shui)(shui)(shui)底(di)產生(sheng)空(kong)化(hua)腐(fu)蝕(shi)更嚴重(zhong),因(yin)此(ci)要(yao)按實際使用情況選擇(ze)(ze)超聲(sheng)功(gong)率(lv)(lv)。 二、頻率(lv)(lv)的(de)選擇(ze)(ze) 超聲(sheng)清(qing)(qing)洗(xi)(xi)(xi)頻率(lv)(lv)從28kHz到(dao)120kHz之(zhi)間,在使用水(shui)(shui)(shui)(shui)或(huo)水(shui)(shui)(shui)(shui)清(qing)(qing)洗(xi)(xi)(xi)劑(ji)時(shi)由(you)空(kong)穴作用引(yin)起的(de)物理清(qing)(qing)洗(xi)(xi)(xi)力顯(xian)然(ran)對(dui)低頻有(you)利(li),一般使用28-40kHz左右。對(dui)小(xiao)(xiao)(xiao)間隙、狹(xia)縫(feng)、深孔的(de)零(ling)件清(qing)(qing)洗(xi)(xi)(xi),用高頻(一般40kHz以上(shang))較好,甚至(zhi)幾百(bai)kHz。對(dui)鐘(zhong)表零(ling)件清(qing)(qing)洗(xi)(xi)(xi)時(shi),用400kHz。若用寬帶調頻清(qing)(qing)洗(xi)(xi)(xi),效(xiao)果(guo)更良(liang)好。 三、清(qing)(qing)洗(xi)(xi)(xi)籃(lan)的(de)使用 在清(qing)(qing)洗(xi)(xi)(xi)小(xiao)(xiao)(xiao)零(ling)件物品時(shi),常使用網籃(lan),由(you)于(yu)網眼要(yao)引(yin)起超聲(sheng)衰減,要(yao)特別(bie)引(yin)起注意。當頻率(lv)(lv)為28khz時(shi)使用10mm以上(shang)的(de)網眼為好。 四、清(qing)(qing)洗(xi)(xi)(xi)液溫度的(de)選擇(ze)(ze) 水(shui)(shui)(shui)(shui)清(qing)(qing)洗(xi)(xi)(xi)液最適(shi)宜的(de)清(qing)(qing)洗(xi)(xi)(xi)溫度為40-60℃,尤其在天(tian)冷時(shi)若清(qing)(qing)洗(xi)(xi)(xi)液溫度低空(kong)化(hua)效(xiao)應差,清(qing)(qing)洗(xi)(xi)(xi)效(xiao)果(guo)也差。因(yin)此(ci)有(you)部分清(qing)(qing)洗(xi)(xi)(xi)機在清(qing)(qing)洗(xi)(xi)(xi)缸外邊繞上(shang)加熱電(dian)熱絲進行溫度控制,當溫度升高后(hou)空(kong)化(hua)易發生(sheng),所以清(qing)(qing)洗(xi)(xi)(xi)...
