超声波清洗机生产厂家讲解超声波清洗机中的匹配电路

超声波清洗机中的匹配电路是将发生器输出的电能送往换能器的通道。匹配电路虽然结构简单(通常

The matching circuit in ultrasonic cleaning machine is the generator output power sent to the transducer channels. The matching circuit has simple structure (usually

只有一个匹配电感),却具有重要作用。相同型号的清洗机,匹配调得好的清洗效果好;匹配调的差的清洗

There is only one matching inductor), has an important role. Cleaning machine of the same type, matching the cleaning effect have good matching adjustable poor cleaning;

效果差。对同一台机器而言,如果工作一段时间后清洗效果变差,或者换能器经过更换,都需要重新调整

Poor effect. On the same machine, if you work for a period of time after the cleaning effect is poor, or transducer after replacement, need to re adjust

匹配。与一般电子设备的匹配有所不同,超声波清洗机的匹配除了要解决变阻问题(即变换负载的阻值,

Matching. Unlike matching electronic equipment, ultrasonic cleaning machine in addition to solve the problem of matching variable resistance (i.e. transform load resistance,

使之与发生器的最佳负载值相等)外,还要解决调谐问题,即用匹配电感的感抗抵消换能器的容抗,使换

The equal value of optimum load and generator), but also solve the tuning problem, with capacitive reactance cancellation transducer matching inductance,.

能器呈纯阻性。技术人员通常是根据各自的经验进行匹配。例如,有人在改变清洗槽水位时观察电流的变

It is a pure resistance. Technical staff is usually matched according to their experiences. For example, some people observe the current changes in the water level of the cleaning tank

化,如果电流变化处于一定范围之内,同时管子不发热,空化声强,便认为匹配已调好。也有人让机器空

If the current change, in a certain range, while the pipe is not heating, cavitation intensity, then that matching has been adjusted. Some people let air machines

载时稍微呈电感性,而在加载后转变为纯阻状态。这些经验都是适用的。但在已有经验的基础上,再掌握

When the load is inductive slightly, and after loading into pure resistance state. These experiences are applicable. But based on previous experience, and master the

匹配的原理,就可以在匹配时有的放矢,更加主动,从而收到事半功倍的效果。
