    超声波清(qing)洗(xi)机(ji)的主要参数

    超声(sheng)(sheng)波清(qing)(qing)洗(xi)是基於空化作用(yong),即在清(qing)(qing)洗(xi)液(ye)(ye)(ye)中无数(shu)气泡快速(su)形成(cheng)并迅速(su)内爆。由此(ci)(ci)产生的(de)冲(chong)击(ji)将浸没在清(qing)(qing)洗(xi)液(ye)(ye)(ye)中的(de)工件内外表面的(de)污(wu)物(wu)剥(bo)落下(xia)来。随(sui)着(zhe)超声(sheng)(sheng)频(pin)(pin)率的(de)提(ti)高(gao),气泡数(shu)量增加(jia)而(er)爆破冲(chong)击(ji)力减弱,因此(ci)(ci),高(gao)频(pin)(pin)超声(sheng)(sheng)特别适用(yong)於小颗粒污(wu)垢的(de)清(qing)(qing)洗(xi)而(er)不(bu)破环其工件表面。气泡是在液(ye)(ye)(ye)体中施加(jia)高(gao)频(pin)(pin)(超声(sheng)(sheng)频(pin)(pin)率)、高(gao)强度(du)的(de)声(sheng)(sheng)波而(er)产生的(de)。因此(ci)(ci),任何超声(sheng)(sheng)清(qing)(qing)洗(xi)系(xi)统都须具备(bei)三个基本元件:盛放清(qing)(qing)洗(xi)液(ye)(ye)(ye)的(de)槽、将电能(neng)转化为(wei)机械能(neng)的(de)换能(neng)器以及产生高(gao)频(pin)(pin)电信(xin)号的(de)超声(sheng)(sheng)波发生器。

    (1)频(pin)(pin)率(lv):≥20KHz,可以(yi)分为低频(pin)(pin),中频(pin)(pin),高频(pin)(pin)3段。

    (2)清(qing)(qing)洗(xi)介质:采用(yong)超(chao)声波(bo)清(qing)(qing)洗(xi),一般两类清(qing)(qing)洗(xi)剂(ji):化学溶剂(ji)、水基清(qing)(qing)洗(xi)剂(ji)等。清(qing)(qing)洗(xi)介质的化学作用(yong),可(ke)以加速(su)超(chao)声波(bo)清(qing)(qing)洗(xi)效果(guo),超(chao)声波(bo)清(qing)(qing)洗(xi)是物理作用(yong),两种(zhong)作用(yong)相结合,以对物件(jian)进行充分、清(qing)(qing)洗(xi)。

    (3)功率(lv)(lv)密(mi)度(du)(du):功率(lv)(lv)密(mi)度(du)(du)=发射功率(lv)(lv)(W)/发射面积(ji)(cm2)通常≥0.3W/cm2,超声波的功率(lv)(lv)密(mi)度(du)(du)越高,空化效果(guo)越强,速度(du)(du)越快(kuai),清洗(xi)效果(guo)越好。但对于表(biao)面光洁度(du)(du)甚高的物(wu)件,采用长时(shi)间的高功率(lv)(lv)密(mi)度(du)(du)清洗(xi)会(hui)对物(wu)件表(biao)面产生“空化”腐蚀。

    (4)超(chao)声波频率(lv)(lv):超(chao)声波频率(lv)(lv)越低,在液体(ti)中产生(sheng)的空化越容(rong)易,产生(sheng)的力度(du)大(da),作用(yong)(yong)也越强,适用(yong)(yong)于工件(粗、脏)初洗(xi)(xi)。频率(lv)(lv)高则(ze)超(chao)声波方向性强,适用(yong)(yong)于精细的物件清(qing)洗(xi)(xi)。

    (5)清(qing)洗(xi)温(wen)度:一般来说,超(chao)声波在30℃-40℃时的(de)空化效果较(jiao)好。清(qing)洗(xi)剂则温(wen)度越高(gao),作(zuo)(zuo)用(yong)越显著。通(tong)常实际应(ying)用(yong)超(chao)声波时,采用(yong)50℃-70℃的(de)工作(zuo)(zuo)温(wen)度。

    超声(sheng)波清洗机使(shi)用注意(yi)事项:

    (1)超(chao)声波清洗机电(dian)源及电(dian)热器(qi)电(dian)源须有良好接(jie)地装(zhuang)置。

    (2)超(chao)声波(bo)清洗(xi)(xi)机(ji)严禁无清洗(xi)(xi)液开机(ji),即清洗(xi)(xi)缸没有加(jia)一定数量的清洗(xi)(xi)液,不得合超(chao)声波(bo)开关。

    (3)有(you)加(jia)热设备的清(qing)洗设备严禁(jin)无液时打开(kai)加(jia)热开(kai)关。

    (4)禁(jin)止用(yong)重物(铁件)撞(zhuang)击清洗缸(gang)缸(gang)底(di),以免能(neng)量转(zhuan)换器晶片受损(sun)。

    (5)超声(sheng)波(bo)发生器(qi)电(dian)源(yuan)应单独(du)使用一路220V/50Hz电(dian)源(yuan)并(bing)配(pei)装2000W以上稳压(ya)器(qi)。

    (6)清洗缸缸底要定期冲洗,不得有过多(duo)的杂物(wu)或(huo)污垢。

    (7)每(mei)次换新(xin)液时,待超声波起动后,方(fang)可(ke)洗件。
