超声波清洗机的高频驱动和匹配电路的设计方法

来源:http://www.sinokohl.com/ 时间: 2022-09-23 浏览次数: 0

超声发生器与一般放大器的一个重要区别在于它的匹配电路部分。一般放大器与负载之间的匹配只牵涉到阻抗变换,而超声波发生器与负载之间的匹配则除了阻抗变换之外,还有一项很重要的内容—调谐,即选用一定值的阻抗元件,使之在工作频率上与负载中的电抗成分谐振。只有在同时进行了阻抗变换和调谐之后,整个系统才算是达到了匹配,换能器才能正常工作。
An important difference between ultrasonic generator and general amplifier is its matching circuit. In general, the matching between amplifier and load only involves impedance transformation. In addition to impedance transformation, the matching between ultrasonic generator and load also has a very important content - tuning, that is, selecting a certain value of impedance element to make it resonant with the reactance component in the load at the operating frequency. Only after the impedance transformation and tuning are carried out at the same time, the whole system can be considered as matching, and the transducer can work normally.
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;匹配调得差的则清洗效果差。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,都需要重新调整匹配。与一般电子设备的匹配有所不同,超声清洗机的匹配除了要变阻问题(即变换负载的阻值,使之与发生器的负载值相等)外,还要调谐问题,即用匹配电感的感抗抵消换能器的容抗,使换能器呈纯阻性。
The matching circuit in the ultrasonic cleaning machine is the channel to send the electrical energy output by the generator to the transducer. Although the matching circuit has a simple structure (usually only one matching inductor), it plays an important role. The cleaning machine of the same model has good cleaning effect if it is well matched and adjusted; If the matching adjustment is poor, the cleaning effect is poor. For the same machine, if the cleaning effect becomes worse after working for a period of time, or the transducer is replaced, readjustment and matching are required. Different from the matching of general electronic equipment, the matching of ultrasonic cleaning machine should not only solve the problem of variable resistance (that is, change the resistance value of the load to make it equal to the load value of the generator), but also solve the problem of tuning, that is, offset the capacitive reactance of the transducer with the inductance matching, so that the transducer is pure resistance.
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,再掌握匹配的原理,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。纯水设备,超声波洗机机,苏州全自动超声波清洗设备。苏州超声波清洗机,
Technicians usually match according to their own experience. For example, someone observes the change of current when changing the water level of the cleaning tank. If the current change is within a certain range, and the pipe does not generate heat, the cavitation sound intensity is considered to have been adjusted. Some people make the machine slightly inductive when it is unloaded, but it changes to pure resistance state after loading. These experiences are applicable. However, on the basis of existing experience, if you master the principle of matching, you can have a definite aim and be more active in matching, so that you can get twice the result with half the effort.
