一(yi)、功(gong)率(lv)(lv)(lv)的(de)選(xuan)擇(ze)(ze)(ze) 超聲(sheng)波(bo)清(qing)洗(xi)(xi)效(xiao)果(guo)不一(yi)定與(功(gong)率(lv)(lv)(lv)×清(qing)洗(xi)(xi)時(shi)(shi)(shi)(shi)(shi)間(jian))成正比,有(you)(you)時(shi)(shi)(shi)(shi)(shi)用(yong)(yong)(yong)小(xiao)功(gong)率(lv)(lv)(lv),花費很長時(shi)(shi)(shi)(shi)(shi)間(jian)也(ye)(ye)沒有(you)(you)清(qing)除(chu)污垢。而如(ru)果(guo)功(gong)率(lv)(lv)(lv)達到(dao)一(yi)定數(shu)值,有(you)(you)時(shi)(shi)(shi)(shi)(shi)很快便將污垢去除(chu)。若(ruo)選(xuan)擇(ze)(ze)(ze)功(gong)率(lv)(lv)(lv)太大(da),空(kong)(kong)化強度將大(da)大(da)增加,清(qing)洗(xi)(xi)效(xiao)果(guo)是(shi)提高了,但這時(shi)(shi)(shi)(shi)(shi)使(shi)(shi)較(jiao)精(jing)密的(de)零件也(ye)(ye)產(chan)生(sheng)蝕點,得不償(chang)失,而且清(qing)洗(xi)(xi)缸底(di)部振(zhen)動板處空(kong)(kong)化嚴重(zhong),水(shui)(shui)(shui)點腐(fu)(fu)蝕也(ye)(ye)增大(da),在(zai)采用(yong)(yong)(yong)三(san)氯(lv)乙烯等有(you)(you)機溶(rong)(rong)劑(ji)時(shi)(shi)(shi)(shi)(shi),基(ji)本上(shang)沒有(you)(you)問題(ti),但采用(yong)(yong)(yong)水(shui)(shui)(shui)或水(shui)(shui)(shui)溶(rong)(rong)性清(qing)洗(xi)(xi)液(ye)時(shi)(shi)(shi)(shi)(shi),易(yi)(yi)于受到(dao)水(shui)(shui)(shui)點腐(fu)(fu)蝕,如(ru)果(guo)振(zhen)動板表面已受到(dao)傷(shang)痕(hen),強功(gong)率(lv)(lv)(lv)下水(shui)(shui)(shui)底(di)產(chan)生(sheng)空(kong)(kong)化腐(fu)(fu)蝕更嚴重(zhong),因(yin)此要(yao)按實際使(shi)(shi)用(yong)(yong)(yong)情況選(xuan)擇(ze)(ze)(ze)超聲(sheng)功(gong)率(lv)(lv)(lv)。 二、頻率(lv)(lv)(lv)的(de)選(xuan)擇(ze)(ze)(ze) 超聲(sheng)清(qing)洗(xi)(xi)頻率(lv)(lv)(lv)從28kHz到(dao)120kHz之(zhi)間(jian),在(zai)使(shi)(shi)用(yong)(yong)(yong)水(shui)(shui)(shui)或水(shui)(shui)(shui)清(qing)洗(xi)(xi)劑(ji)時(shi)(shi)(shi)(shi)(shi)由空(kong)(kong)穴(xue)作用(yong)(yong)(yong)引起(qi)的(de)物理清(qing)洗(xi)(xi)力顯然對(dui)低(di)頻有(you)(you)利,一(yi)般使(shi)(shi)用(yong)(yong)(yong)28-40kHz左(zuo)右。對(dui)小(xiao)間(jian)隙、狹縫、深孔的(de)零件清(qing)洗(xi)(xi),用(yong)(yong)(yong)高頻(一(yi)般40kHz以(yi)(yi)上(shang))較(jiao)好,甚至幾百(bai)kHz。對(dui)鐘(zhong)表零件清(qing)洗(xi)(xi)時(shi)(shi)(shi)(shi)(shi),用(yong)(yong)(yong)400kHz。若(ruo)用(yong)(yong)(yong)寬(kuan)帶(dai)調頻清(qing)洗(xi)(xi),效(xiao)果(guo)更良好。 三(san)、清(qing)洗(xi)(xi)籃的(de)使(shi)(shi)用(yong)(yong)(yong) 在(zai)清(qing)洗(xi)(xi)小(xiao)零件物品時(shi)(shi)(shi)(shi)(shi),常使(shi)(shi)用(yong)(yong)(yong)網籃,由于網眼要(yao)引起(qi)超聲(sheng)衰減,要(yao)特別引起(qi)注意。當頻率(lv)(lv)(lv)為28khz時(shi)(shi)(shi)(shi)(shi)使(shi)(shi)用(yong)(yong)(yong)10mm以(yi)(yi)上(shang)的(de)網眼為好。 四、清(qing)洗(xi)(xi)液(ye)溫度的(de)選(xuan)擇(ze)(ze)(ze) 水(shui)(shui)(shui)清(qing)洗(xi)(xi)液(ye)最適(shi)宜的(de)清(qing)洗(xi)(xi)溫度為40-60℃,尤其在(zai)天(tian)冷時(shi)(shi)(shi)(shi)(shi)若(ruo)清(qing)洗(xi)(xi)液(ye)溫度低(di)空(kong)(kong)化效(xiao)應差,清(qing)洗(xi)(xi)效(xiao)果(guo)也(ye)(ye)差。因(yin)此有(you)(you)部分清(qing)洗(xi)(xi)機在(zai)清(qing)洗(xi)(xi)缸外邊(bian)繞上(shang)加熱(re)電熱(re)絲進(jin)行溫度控(kong)制,當溫度升(sheng)高后空(kong)(kong)化易(yi)(yi)發(fa)生(sheng),所(suo)以(yi)(yi)清(qing)洗(xi)(xi)...
