超聲波清洗機(jī)由超聲波發(fā)生器和超聲波換能器組成，超聲波換能器是由壓電陶瓷材料制造的夾芯式換能器，壓電陶瓷材料在交變電場(chǎng)的作用下會(huì)產(chǎn)生機(jī)械振動(dòng)。

Ultrasonic cleaning machine is composed of ultrasonic generator and ultrasonic transducer. Ultrasonic transducer is a sandwich transducer made of piezoelectric ceramic materials. Piezoelectric ceramic materials will produce mechanical vibration under the action of alternating electric field.

超聲波換能器是超聲波清洗機(jī)的重要組成部分，超聲波清洗機(jī)出現(xiàn)問(wèn)題的時(shí)候很可能就是超聲波換能器出現(xiàn)問(wèn)題，本文就將帶大家了解下超聲波清洗機(jī)換能器常見(jiàn)的四大問(wèn)題：

The ultrasonic transducer is an important part of the ultrasonic cleaning machine. When the ultrasonic cleaning machine has problems, it is likely that the ultrasonic transducer has problems. This paper will take you to understand the four common problems of the ultrasonic cleaning machine transducer

1.超聲波換能器受潮。一般用兆歐表檢查和換能器相連接的插頭，檢查換能器正負(fù)極間的絕緣電阻值就可以判斷。一般要求絕緣電阻大于30兆歐以上。如果達(dá)不到這個(gè)絕緣電阻值，很可能是換能器受潮。

1. The ultrasonic transducer is damp. Generally, the plug connected to the transducer is checked with a megohmmeter, and the insulation resistance value between the positive and negative poles of the transducer can be judged. Generally, the insulation resistance is more than 30 megohm. If the insulation resistance value is not reached, it is likely that the transducer is affected by moisture.

維修方法是把換能器整體(不包括噴塑外殼)放進(jìn)烘箱設(shè)定100℃左右，烘干三小時(shí)或者使用電吹風(fēng)去潮至阻值正常為止。換能器振子打火，陶瓷材料碎裂。維修時(shí)可以用肉眼和兆歐表結(jié)合檢查。一般作為應(yīng)急處理的措施，可以把個(gè)別損壞的換能器斷開(kāi)，不會(huì)影響到別的換能器正常使用。

The maintenance method is to put the whole transducer (excluding the plastic spraying shell) into the oven, set it at about 100 ℃, dry it for three hours or use an electric hair dryer to remove moisture until the resistance is normal. The transducer vibrator ignited and the ceramic material was broken. During maintenance, it can be checked with naked eye and megohmmeter. Generally, as an emergency measure, individual damaged transducers can be disconnected, which will not affect the normal use of other transducers.

2.換能器脫膠。我們知道大多數(shù)廠家采用膠粘的方式固定換能器，但超聲波清洗機(jī)的長(zhǎng)期使用后由于振動(dòng)會(huì)出現(xiàn)脫膠現(xiàn)象。也有廠家采用膠結(jié)加螺釘緊固的方式，一般情況下不會(huì)出現(xiàn)脫膠，由于螺釘?shù)淖饔茫褡用撃z后不會(huì)從振動(dòng)面上落下，一般的判斷方法是用手輕搖振子的尾部，仔細(xì)觀察振動(dòng)面的膠水情況做出判斷。

2. Transducer degumming. We know that most manufacturers use adhesive way to fix the transducer, but after long-term use of ultrasonic cleaning machine, it will appear degumming phenomenon due to vibration. Some manufacturers also adopt the way of cementation and screw fastening, which generally will not occur degumming. Due to the role of the screw, the vibrator will not fall from the vibration surface after degumming. The general judgment method is to gently shake the tail of the vibrator by hand, carefully observe the glue situation of the vibration surface, and make a judgment.

3.一般振子出現(xiàn)脫膠以后超聲波

3. After the general vibrator appears degumming, ultrasonic

電源輸出的功率正常，但是由于振子與振動(dòng)面連接不好，振動(dòng)面的振動(dòng)效果不好，長(zhǎng)時(shí)間后由于能量無(wú)法釋放出去，很可能會(huì)燒壞振子。振子脫膠對(duì)于用戶來(lái)說(shuō)維修起來(lái)是比較麻煩的，一般情況只能送回生產(chǎn)廠家進(jìn)行維修處理。避免振子脫膠有用的方法是平時(shí)使用中注意不撞擊振動(dòng)面。

The power output of the power supply is normal, but the vibration effect of the vibration surface is not good due to the poor connection between the vibrator and the vibration surface. After a long time, because the energy can not be released, the vibrator is likely to be burnt out. Vibration degumming is troublesome for the user to maintain. Generally, it can only be sent back to the manufacturer for maintenance. A useful way to avoid the degumming of the vibrator is not to hit the vibrating surface in normal use.

4.振動(dòng)面穿孔。一般超聲波換能器滿負(fù)荷使用數(shù)年以后可能會(huì)出現(xiàn)振動(dòng)面穿孔的情況，這是由于振動(dòng)面的不銹鋼板長(zhǎng)時(shí)間高頻振動(dòng)疲勞所致，振動(dòng)面穿孔說(shuō)明換能器的使用壽命已經(jīng)到了，超聲波清洗機(jī)在維修上一般只能更換。

4. The vibration surface is perforated. In general, after the ultrasonic transducer is used at full load for several years, the vibration surface may be perforated, which is caused by the high frequency vibration fatigue of the stainless steel plate of the vibration surface for a long time. The perforation of the vibration surface indicates that the service life of the transducer has come, and the ultrasonic cleaning machine can only be replaced in the maintenance.
