1、电路短路:
线路接错,或者是线路老化等,都有可能导致电路发生短路,从而导致超声波清洗机发生跳闸。
解决措施:纠正错误接线,或者是更换老化的线路。
2、整流桥短路
超声波发生器的整流桥发生短路,也会导致超声波清洗机跳闸。
解决措施:
用万用表的二极管档,逐个测量其整流桥的管教,如果发现有短路的管脚,则证明整流桥已经损毁,需要更换新的整流桥。
3、清洗频率设定不合适:
超声波清洗机里面的物品过多,且设定的清洗频率很高的情况下,易产生跳闸现象。
解决措施:
降低清洗频率。
二、关于超声波清洗机:
超声波在液体中传播,使液体与清洗槽在超声波频率下一起振动,液体与清洗槽振动时有自己固有频率,这种振动频率是声波频率,所以人们就听到嗡嗡声。随着清洗行业的不断发展,越来越多的行业和企业运用到了超声波清洗机。
对超声波清洗机原理由超声波发生器发出的高频振荡信号,通过换能器转换成高频机械振荡而传播到介质--清洗溶剂中,超声波在清洗液中疏密相间的向前辐射,使液体流动而产生数以万计的直径为50-500μm 的微小气泡,存在于液体中的微小气泡在声场的作用下振动。这些气泡在超声波纵向传播的负压区形成、生长,而在正压区,当声压达到一定值时,气泡迅速增大,然后突然闭合。并在气泡闭合时产生冲击波,在其周围产生上千个大气压,破坏不溶性污物而使他们分散于清洗液中,当团体粒子被油污裹着而黏附在清洗件表面时,油被乳化,固体粒子及脱离,从而达到清洗件净化的目的。在这种被称之为“空化”效应的过程中,气泡闭合可形成几百度的高温和超过1000个气压的瞬间高压。
超声波清洗机的优点是:超声波清洗效果好,操作简单。人们所听到的声音是频率20-20000Hz的声波信号,高于20000Hz的声波称之为超声波,声波的传递依照正弦曲线纵向传播,产生大量小气泡 。一个原因是液体内局部出现拉应力而形成负压,压强的降低使原来溶于液体的气体过饱和,而从液体逸出,成为小气泡;另一原因是强大的拉应力把液体“撕开”成一空洞,称为空化。
但当超声波功率弱的时候,就不是清洗时间长与短的问题了,
而在28KHz到128KHz之间主要用在工序间洗净,40KHz以下的换能器主要用于五金类精密金属类,它强度大,但粗糙,一般精密光学零件都是采用超高频换能器,目前国内的洗净设备还没有达到兆赫兹的制造水平!日本的可以
楼主的问题还不好回答,洗净时间的长短与被洗物及洗净液有关,而并非是越长越好!
只是120KHz的超声机比28KHz的超声机价格高三倍,更高频率的恐怕更是吓人哟。有5分钟的 ,也有半小时的。也和你医疗器械的难易有关,比如含油含血的还是只表面的灰尘的清洗呢!
1、使用前请仔细阅读使用说明书。
2、使用清洗机前,必须有可靠的接地装置。
3、工作现场严禁携带火种及明火作业。(使用酒精、丙酮、汽油、等挥发易燃液体时,应加盖,此时严禁使用加热功能。)
4、清洗液温度最好不高于60℃,否则会影响清洗效果,一般为常温和状态下即可。
5、槽内无清洗液,不得开机,以免清洗机空载损坏。
6、清洗机长期不用时,应将槽内清洗液放掉,并将机体擦洗干净。
7、清洗机应放置在干燥、清洁的房间使用,严禁在潮湿、污染、阳光直射的地方使用。

2、超声波清洗槽尺寸选择:根据工件大小和清洗量决定。
3、超声波清洗剂的选择:以传统方法用到的清洗剂是一样的,不需要更换。
4、超声波频率的选择:常规的是28KHZ和40KHZ,28KHZ的特点是超声威力大,超声次数少,适合清洗清洁度有一定要求的工件。40KHZ的特点是超声威力小,超声次数多,适合清洗清洁度要求不高的工件。
5、超声波功率的选择:根据清洗槽的尺寸来确定功率大小。每个50W的换能器之间的距离为80mm,根据这个行业标准,可以算出功率大小。
6、配件选择:韩国逸山超声波换能器、第六代超声波发生器、SUS304槽体、进口胶水和种钉双重固定。
7、超声波清洗液温度的选择:常温-100度,具备恒温系统,一直保持这样的温度。比如:可以在60度的时候,去油效果更佳。
8、超声波安装方式的选择:超声波安装方式有:底部安装、两侧安装、底部和两侧三面同时安装。底部安装又叫做底震式,超声波的有效作用高度为500mm,两侧安装是侧震,超声波的有效作用长度为1000mm,有效作用高度与换能器的位置有关。底部和两侧三面同时安装,是三面震,超声波的有效作用长度不能超过1000mm,高度可以调整。
2、超声波清洗工件时,所标的功率大多是声频功率而不是电功率。一般超声波清洗机所标,是指消耗工频功率,而超声波清洗质量优劣是由效率来判断。如果效率低,在同样清洗效果时则会耗电大,这样反而增加了用户的费用。
总之,超声波清洗机不是功率越大清洗工件就会越干净,买超声波清洗机时因根据工件要求选择合适的功率。力华机械是专业生产超声波清洗机厂家,可根据您的需求非标订制各种超声波清洗设备。
铭扬超声波清洗机小编为您解答:超声波清洗机的power99%是你机台额定功率的百分比,意思就是机台额定功率是1000W,power99%显示现在机台工作功率达到了990W
还有水箱温度的控制
1、看频率:F≥20KHz(在实际应用中因为效果相似,通常把F≥15K的声波也称为超声波)。
2、看功率密度:p=发射功率(W)/发射面积(cm2);通常p≥0.3w/cm2;在液体中传播的超声波能对物体表面的污物进行清洗,其原理可用“空化”现象。
