一、功(gong)率(lv)(lv)(lv)的(de)(de)選擇(ze) 超(chao)聲(sheng)(sheng)波清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)效果不一定(ding)與(功(gong)率(lv)(lv)(lv)×清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)時(shi)(shi)間(jian))成正比,有(you)時(shi)(shi)用(yong)(yong)小(xiao)功(gong)率(lv)(lv)(lv),花(hua)費(fei)很長時(shi)(shi)間(jian)也(ye)沒有(you)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)除(chu)污垢(gou)。而如果功(gong)率(lv)(lv)(lv)達到(dao)一定(ding)數(shu)值,有(you)時(shi)(shi)很快便將污垢(gou)去(qu)除(chu)。若選擇(ze)功(gong)率(lv)(lv)(lv)太大(da)(da)(da),空(kong)(kong)化(hua)(hua)強度將大(da)(da)(da)大(da)(da)(da)增(zeng)加,清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)效果是提高了,但這時(shi)(shi)使(shi)(shi)較(jiao)精密的(de)(de)零件也(ye)產生(sheng)蝕(shi)點(dian),得不償(chang)失,而且清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)缸底部振(zhen)動(dong)板處空(kong)(kong)化(hua)(hua)嚴重(zhong),水(shui)(shui)點(dian)腐蝕(shi)也(ye)增(zeng)大(da)(da)(da),在采(cai)用(yong)(yong)三氯乙烯等有(you)機溶劑時(shi)(shi),基本(ben)上(shang)沒有(you)問題,但采(cai)用(yong)(yong)水(shui)(shui)或水(shui)(shui)溶性清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)液時(shi)(shi),易于(yu)受到(dao)水(shui)(shui)點(dian)腐蝕(shi),如果振(zhen)動(dong)板表面已受到(dao)傷(shang)痕(hen),強功(gong)率(lv)(lv)(lv)下水(shui)(shui)底產生(sheng)空(kong)(kong)化(hua)(hua)腐蝕(shi)更(geng)嚴重(zhong),因(yin)(yin)此要按實際(ji)使(shi)(shi)用(yong)(yong)情況選擇(ze)超(chao)聲(sheng)(sheng)功(gong)率(lv)(lv)(lv)。 二(er)、頻(pin)(pin)率(lv)(lv)(lv)的(de)(de)選擇(ze) 超(chao)聲(sheng)(sheng)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)頻(pin)(pin)率(lv)(lv)(lv)從28kHz到(dao)120kHz之間(jian),在使(shi)(shi)用(yong)(yong)水(shui)(shui)或水(shui)(shui)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)劑時(shi)(shi)由(you)空(kong)(kong)穴(xue)作用(yong)(yong)引起(qi)的(de)(de)物(wu)理清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)力顯然對低頻(pin)(pin)有(you)利,一般使(shi)(shi)用(yong)(yong)28-40kHz左右(you)。對小(xiao)間(jian)隙(xi)、狹(xia)縫、深孔的(de)(de)零件清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi),用(yong)(yong)高頻(pin)(pin)(一般40kHz以上(shang))較(jiao)好,甚至幾百(bai)kHz。對鐘表零件清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)時(shi)(shi),用(yong)(yong)400kHz。若用(yong)(yong)寬帶調頻(pin)(pin)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi),效果更(geng)良好。 三、清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)籃的(de)(de)使(shi)(shi)用(yong)(yong) 在清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)小(xiao)零件物(wu)品(pin)時(shi)(shi),常使(shi)(shi)用(yong)(yong)網(wang)(wang)籃,由(you)于(yu)網(wang)(wang)眼要引起(qi)超(chao)聲(sheng)(sheng)衰減,要特(te)別引起(qi)注意。當(dang)頻(pin)(pin)率(lv)(lv)(lv)為28khz時(shi)(shi)使(shi)(shi)用(yong)(yong)10mm以上(shang)的(de)(de)網(wang)(wang)眼為好。 四、清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)液溫度的(de)(de)選擇(ze) 水(shui)(shui)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)液最適宜的(de)(de)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)溫度為40-60℃,尤其在天冷時(shi)(shi)若清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)液溫度低空(kong)(kong)化(hua)(hua)效應差,清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)效果也(ye)差。因(yin)(yin)此有(you)部分清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)機在清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)缸外邊繞上(shang)加熱(re)電(dian)熱(re)絲進行溫度控制,當(dang)溫度升高后空(kong)(kong)化(hua)(hua)易發生(sheng),所以清(qing)(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)...
