一(yi)、功(gong)(gong)率(lv)(lv)(lv)的(de)(de)選(xuan)擇 超(chao)聲波(bo)清(qing)(qing)洗(xi)(xi)(xi)效(xiao)(xiao)果不(bu)(bu)一(yi)定(ding)與(功(gong)(gong)率(lv)(lv)(lv)×清(qing)(qing)洗(xi)(xi)(xi)時(shi)(shi)(shi)間(jian)(jian))成正(zheng)比,有(you)(you)時(shi)(shi)(shi)用小(xiao)功(gong)(gong)率(lv)(lv)(lv),花(hua)費很長(chang)時(shi)(shi)(shi)間(jian)(jian)也沒有(you)(you)清(qing)(qing)除(chu)污垢。而如(ru)果功(gong)(gong)率(lv)(lv)(lv)達到(dao)一(yi)定(ding)數值,有(you)(you)時(shi)(shi)(shi)很快(kuai)便(bian)將污垢去除(chu)。若選(xuan)擇功(gong)(gong)率(lv)(lv)(lv)太大(da),空(kong)化(hua)(hua)強度(du)將大(da)大(da)增加,清(qing)(qing)洗(xi)(xi)(xi)效(xiao)(xiao)果是提高了,但(dan)這時(shi)(shi)(shi)使(shi)較(jiao)精密的(de)(de)零件(jian)也產(chan)生(sheng)蝕點(dian),得不(bu)(bu)償失,而且清(qing)(qing)洗(xi)(xi)(xi)缸(gang)底(di)部振動(dong)板處空(kong)化(hua)(hua)嚴重(zhong),水(shui)點(dian)腐(fu)(fu)蝕也增大(da),在采(cai)用三氯乙烯等有(you)(you)機溶(rong)劑時(shi)(shi)(shi),基本上(shang)(shang)沒有(you)(you)問題,但(dan)采(cai)用水(shui)或水(shui)溶(rong)性(xing)清(qing)(qing)洗(xi)(xi)(xi)液時(shi)(shi)(shi),易于受(shou)到(dao)水(shui)點(dian)腐(fu)(fu)蝕,如(ru)果振動(dong)板表(biao)(biao)面已受(shou)到(dao)傷痕,強功(gong)(gong)率(lv)(lv)(lv)下水(shui)底(di)產(chan)生(sheng)空(kong)化(hua)(hua)腐(fu)(fu)蝕更(geng)嚴重(zhong),因此要(yao)按實(shi)際使(shi)用情況(kuang)選(xuan)擇超(chao)聲功(gong)(gong)率(lv)(lv)(lv)。 二、頻(pin)(pin)(pin)(pin)(pin)率(lv)(lv)(lv)的(de)(de)選(xuan)擇 超(chao)聲清(qing)(qing)洗(xi)(xi)(xi)頻(pin)(pin)(pin)(pin)(pin)率(lv)(lv)(lv)從28kHz到(dao)120kHz之間(jian)(jian),在使(shi)用水(shui)或水(shui)清(qing)(qing)洗(xi)(xi)(xi)劑時(shi)(shi)(shi)由(you)空(kong)穴(xue)作用引起(qi)的(de)(de)物(wu)理清(qing)(qing)洗(xi)(xi)(xi)力顯然對低(di)頻(pin)(pin)(pin)(pin)(pin)有(you)(you)利,一(yi)般使(shi)用28-40kHz左右。對小(xiao)間(jian)(jian)隙、狹(xia)縫、深(shen)孔的(de)(de)零件(jian)清(qing)(qing)洗(xi)(xi)(xi),用高頻(pin)(pin)(pin)(pin)(pin)(一(yi)般40kHz以(yi)上(shang)(shang))較(jiao)好,甚至幾百kHz。對鐘表(biao)(biao)零件(jian)清(qing)(qing)洗(xi)(xi)(xi)時(shi)(shi)(shi),用400kHz。若用寬帶調頻(pin)(pin)(pin)(pin)(pin)清(qing)(qing)洗(xi)(xi)(xi),效(xiao)(xiao)果更(geng)良好。 三、清(qing)(qing)洗(xi)(xi)(xi)籃的(de)(de)使(shi)用 在清(qing)(qing)洗(xi)(xi)(xi)小(xiao)零件(jian)物(wu)品時(shi)(shi)(shi),常(chang)使(shi)用網(wang)籃,由(you)于網(wang)眼(yan)要(yao)引起(qi)超(chao)聲衰減,要(yao)特別(bie)引起(qi)注意。當(dang)頻(pin)(pin)(pin)(pin)(pin)率(lv)(lv)(lv)為(wei)(wei)28khz時(shi)(shi)(shi)使(shi)用10mm以(yi)上(shang)(shang)的(de)(de)網(wang)眼(yan)為(wei)(wei)好。 四(si)、清(qing)(qing)洗(xi)(xi)(xi)液溫(wen)度(du)的(de)(de)選(xuan)擇 水(shui)清(qing)(qing)洗(xi)(xi)(xi)液最適宜(yi)的(de)(de)清(qing)(qing)洗(xi)(xi)(xi)溫(wen)度(du)為(wei)(wei)40-60℃,尤其在天冷時(shi)(shi)(shi)若清(qing)(qing)洗(xi)(xi)(xi)液溫(wen)度(du)低(di)空(kong)化(hua)(hua)效(xiao)(xiao)應差,清(qing)(qing)洗(xi)(xi)(xi)效(xiao)(xiao)果也差。因此有(you)(you)部分清(qing)(qing)洗(xi)(xi)(xi)機在清(qing)(qing)洗(xi)(xi)(xi)缸(gang)外(wai)邊繞上(shang)(shang)加熱電熱絲進行溫(wen)度(du)控制,當(dang)溫(wen)度(du)升高后(hou)空(kong)化(hua)(hua)易發生(sheng),所以(yi)清(qing)(qing)洗(xi)(xi)(xi)...
