一、功(gong)率(lv)(lv)(lv)的(de)(de)選擇 超(chao)聲波清(qing)(qing)(qing)洗(xi)(xi)效(xiao)(xiao)(xiao)果(guo)(guo)不一定與(功(gong)率(lv)(lv)(lv)×清(qing)(qing)(qing)洗(xi)(xi)時(shi)(shi)(shi)(shi)間)成正比,有時(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)小功(gong)率(lv)(lv)(lv),花(hua)費很長(chang)時(shi)(shi)(shi)(shi)間也(ye)沒有清(qing)(qing)(qing)除(chu)污(wu)垢。而如(ru)果(guo)(guo)功(gong)率(lv)(lv)(lv)達到(dao)一定數值,有時(shi)(shi)(shi)(shi)很快便將(jiang)污(wu)垢去除(chu)。若(ruo)選擇功(gong)率(lv)(lv)(lv)太大,空(kong)化(hua)強度(du)將(jiang)大大增(zeng)加,清(qing)(qing)(qing)洗(xi)(xi)效(xiao)(xiao)(xiao)果(guo)(guo)是提高了,但(dan)這(zhe)時(shi)(shi)(shi)(shi)使較(jiao)精密的(de)(de)零件(jian)也(ye)產(chan)生(sheng)蝕(shi)(shi)點,得不償(chang)失,而且清(qing)(qing)(qing)洗(xi)(xi)缸底部(bu)振動板處空(kong)化(hua)嚴重,水(shui)(shui)(shui)點腐(fu)蝕(shi)(shi)也(ye)增(zeng)大,在(zai)采用(yong)(yong)(yong)(yong)(yong)三氯(lv)乙烯等有機溶劑時(shi)(shi)(shi)(shi),基(ji)本上沒有問題(ti),但(dan)采用(yong)(yong)(yong)(yong)(yong)水(shui)(shui)(shui)或水(shui)(shui)(shui)溶性清(qing)(qing)(qing)洗(xi)(xi)液時(shi)(shi)(shi)(shi),易于(yu)受到(dao)水(shui)(shui)(shui)點腐(fu)蝕(shi)(shi),如(ru)果(guo)(guo)振動板表面已(yi)受到(dao)傷(shang)痕,強功(gong)率(lv)(lv)(lv)下(xia)水(shui)(shui)(shui)底產(chan)生(sheng)空(kong)化(hua)腐(fu)蝕(shi)(shi)更嚴重,因(yin)此要(yao)按(an)實際使用(yong)(yong)(yong)(yong)(yong)情況選擇超(chao)聲功(gong)率(lv)(lv)(lv)。 二、頻率(lv)(lv)(lv)的(de)(de)選擇 超(chao)聲清(qing)(qing)(qing)洗(xi)(xi)頻率(lv)(lv)(lv)從28kHz到(dao)120kHz之間,在(zai)使用(yong)(yong)(yong)(yong)(yong)水(shui)(shui)(shui)或水(shui)(shui)(shui)清(qing)(qing)(qing)洗(xi)(xi)劑時(shi)(shi)(shi)(shi)由空(kong)穴作用(yong)(yong)(yong)(yong)(yong)引起的(de)(de)物理清(qing)(qing)(qing)洗(xi)(xi)力顯然對(dui)低頻有利,一般使用(yong)(yong)(yong)(yong)(yong)28-40kHz左(zuo)右。對(dui)小間隙、狹縫、深孔的(de)(de)零件(jian)清(qing)(qing)(qing)洗(xi)(xi),用(yong)(yong)(yong)(yong)(yong)高頻(一般40kHz以(yi)上)較(jiao)好(hao),甚至幾百kHz。對(dui)鐘表零件(jian)清(qing)(qing)(qing)洗(xi)(xi)時(shi)(shi)(shi)(shi),用(yong)(yong)(yong)(yong)(yong)400kHz。若(ruo)用(yong)(yong)(yong)(yong)(yong)寬帶(dai)調頻清(qing)(qing)(qing)洗(xi)(xi),效(xiao)(xiao)(xiao)果(guo)(guo)更良好(hao)。 三、清(qing)(qing)(qing)洗(xi)(xi)籃的(de)(de)使用(yong)(yong)(yong)(yong)(yong) 在(zai)清(qing)(qing)(qing)洗(xi)(xi)小零件(jian)物品(pin)時(shi)(shi)(shi)(shi),常使用(yong)(yong)(yong)(yong)(yong)網籃,由于(yu)網眼要(yao)引起超(chao)聲衰減,要(yao)特別引起注意。當(dang)頻率(lv)(lv)(lv)為(wei)28khz時(shi)(shi)(shi)(shi)使用(yong)(yong)(yong)(yong)(yong)10mm以(yi)上的(de)(de)網眼為(wei)好(hao)。 四、清(qing)(qing)(qing)洗(xi)(xi)液溫度(du)的(de)(de)選擇 水(shui)(shui)(shui)清(qing)(qing)(qing)洗(xi)(xi)液最適宜的(de)(de)清(qing)(qing)(qing)洗(xi)(xi)溫度(du)為(wei)40-60℃,尤其(qi)在(zai)天冷時(shi)(shi)(shi)(shi)若(ruo)清(qing)(qing)(qing)洗(xi)(xi)液溫度(du)低空(kong)化(hua)效(xiao)(xiao)(xiao)應差,清(qing)(qing)(qing)洗(xi)(xi)效(xiao)(xiao)(xiao)果(guo)(guo)也(ye)差。因(yin)此有部(bu)分清(qing)(qing)(qing)洗(xi)(xi)機在(zai)清(qing)(qing)(qing)洗(xi)(xi)缸外邊(bian)繞(rao)上加熱電熱絲進行溫度(du)控(kong)制,當(dang)溫度(du)升高后空(kong)化(hua)易發生(sheng),所以(yi)清(qing)(qing)(qing)洗(xi)(xi)...
