超声波清洗机核心的部件就是超声波换能器，那么在以后的使用过程中常见的故障有以下几个：

The core component of the ultrasonic cleaning machine is the ultrasonic transducer. In the future, the common faults are as follows:

1、超声波换能器脱落，这种情况多见于使用时间较长的实验室清洗器，因为大部分厂家实验室用超声波清洗器采用不锈钢拉伸槽，换能器固定只能靠粘胶剂固定，使用时间过长，一般两三年后，换能器就会脱落；工业用超声波清洗机，多采用螺钉加粘胶的固定方式，一般很少出现这种情况。

1. The ultrasonic transducer falls off, which is more common in laboratory cleaners that have been used for a long time, because the ultrasonic cleaners used in most manufacturers' laboratories use stainless steel stretching groove, the transducer can only be fixed by adhesive, and the use time is too long, generally after two or three years, the transducer will fall off; the industrial ultrasonic cleaners mostly use screw and adhesive fixation This is rarely the case.

避免换能器脱落有效的方法是平时使用中注意不撞击振动面。振动面穿孔，一般换能器满负荷使用年以后可能会出现振动面穿孔的情况，这是由于振动面的不锈钢板长时间高频振动疲劳所至，振动面穿孔说明换能器的使用寿命已经到了，一般只能更换。

The effective way to avoid the transducer falling off is to pay attention not to impact the vibration surface in normal use. The vibration surface is perforated. Generally, the vibration surface may be perforated after the transducer has been used for years at full load. This is due to the long-time high-frequency vibration fatigue of the stainless steel plate on the vibration surface. The vibration surface perforation indicates that the service life of the transducer has arrived and can only be replaced.

2、超声波换能器炸裂，工业用超声波清洗机这种问题较为常见，这是有螺钉焊接质量差，不锈钢清洗槽表面不平等原因造成的，另外液体滴在换能器上也会造成换能器炸裂。这种情况下要将炸裂换能器卸下，并对超声波清洗槽进行整形，然后再重新粘结换能器。

2. Ultrasonic transducer burst, industrial ultrasonic cleaning machine this problem is more common, this is a screw welding quality is poor, stainless steel cleaning tank surface is not equal cause, in addition, liquid drops on the transducer will also cause transducer burst. In this case, it is necessary to remove the burst transducer, reshape the ultrasonic cleaning tank, and then re bond the transducer.

3、换能器过热，一般清洗槽装水并开机工作一段时间后，换能器会慢慢升温。如果在众多的换能器中某个换能器温升特别快，则表明该换能器可能粘结不好.因为此时声辐射不好，电能量大部分消耗在换能器上而发热。另一个方法是在小信号条件下逐个测量换能器的电阻抗大小来判别粘结质量。

3. The transducer is overheated. Generally, after the cleaning tank is filled with water and started to work for a period of time, the transducer will slowly heat up. If the temperature rise of one of the transducers is particularly fast, it indicates that the transducer may not bond well. Because the sound radiation is not good at this time, most of the electrical energy is consumed on the transducer and generates heat. Another method is to measure the impedance of transducers one by one under the condition of small signal to judge the bonding quality.

4、超声波换能器衰减，一般超声波清洗机使用2年以上，换能器会形成一定的衰减，震动效果会变得很差，此时，维修后使用寿命也不会太长，维修成本也不低，这样就可以考虑更换新的清洗机。

4. Ultrasonic transducer attenuation, the general ultrasonic cleaning machine used for more than 2 years, the transducer will form a certain attenuation, the vibration effect will become very poor, at this time, the service life after maintenance will not be too long, the maintenance cost is not low, so you can consider replacing a new cleaning machine.
