超声波清洗机主要由超声波发生器和超声波换能器组成,超声波换能器是由锆钛酸铅压电陶瓷材料制造的夹芯式换能器,压电陶瓷材料具有在电场作用下发生尺寸变化的现象,在交变电场的作用下换能器会产生机械振动。   超声波换能器常见问题:   1、超声波振子受潮   可以用兆欧表检查与换能器相连接的插头,其中2脚为超声波换能器的正极, 3脚是换能器的负极而且与换能器的外壳相连。检查,2 3 脚间的绝缘 电阻值就可以判断基本情况,一般要求绝缘 电阻大于30兆欧以上。如果达不到这个绝缘电阻值,一般是换能器受潮,可以把换能器整体(不包括喷塑外壳)放进烘箱设定100 ℃左右烘干3小时或者使用电吹风去潮至阻 值正常为止。   2、换能器振子打火,陶瓷材料碎裂。   可以用肉眼和兆欧表结合检查,一般作为应急处理的措施,可以把个别损坏的振子断开,不会影响到别的振子正常使用。   2、振子脱胶   换能器采用胶结,螺钉紧固双重保证工艺,在一般情况下不会出现这种情况,由于螺钉的作用,振子脱胶后不会从振动面上落下,一般的判断方法是用手轻摇振子。
Ultrasonic cleaning machine is mainly composed of ultrasonic generator and ultrasonic transducer. Ultrasonic transducer is a sandwich transducer made of lead zirconate titanate piezoelectric ceramic material. Piezoelectric ceramic material has the phenomenon of size change under the action of electric field, and the transducer will produce mechanical vibration under the action of alternating electric field. Common problems of ultrasonic transducer: 1. When ultrasonic vibrator is damped, megger can be used to check the plug connected with the transducer, of which 2 pins are positive pole of ultrasonic transducer and 3 pins are negative pole of transducer, which are connected with the shell of transducer. The basic situation can be judged by the insulation resistance value between 23 pins. Generally, the insulation resistance should be more than 30 megohm. If the insulation resistance value is not reached, the transducer is generally affected by moisture. Put the whole transducer (excluding the plastic spraying shell) into the oven, set it at 100 ℃ and dry it for 3 hours or use a hair dryer to remove moisture until the resistance value is normal. 2. The transducer vibrator ignites and the ceramic material is broken. It can be checked by naked eye and megohmmeter. Generally, it can be used as an emergency measure to disconnect individual damaged vibrator, which will not affect the normal use of other vibrators. 2. Due to the screw action, the vibrator will not fall from the vibration surface after degumming. The general judgment method is to gently shake the vibrator by hand
