超声雾化器利用超声波能将药液变成高浓度的微细的气溶胶,雾粒直径大部分在1～5微米范围内。我院有鞍山、上海、浙江等地厂家生产的晶体管和电子管超声雾化器,经几年来的维修实践,发现无论是那一种型号,其一般故障都有共同之处,基本有以下几种:一、输出变弱或无输出主要原因:1.振荡管特性变化使其振荡频率偏离晶片固有频率,产生失谐 2.晶片浸水短路造成振荡管损坏。3.晶片损坏。处理办法:1.老式电子管可调节振荡线圈的磁芯,
Ultrasonic atomizer using ultrasonic energy to the liquid into a high concentration of fine aerosol, most of the fog particle diameter in the range of 1 to 5 microns. Our hospital has Anshan, Shanghai, Zhejiang and other manufacturers of transistors and tube ultrasonic atomizer, after several years of maintenance practice and found that no matter what kind of model, the general breakdown has in common, the basic following : First, the output is weak or no output The main reasons: 1. Oscillation tube characteristics change its oscillation frequency deviation from the natural frequency of the wafer, resulting in detuning 2. wafer immersion caused by short-circuit oscillation tube damage. 3. The chip is damaged. Approach: 1. Old-fashioned tube adjustable oscillation coil core,
