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.

超聲波清洗機(jī)中的匹配電路是將發(fā)生器輸出的電能送往換能器的通道。匹配電路雖然結(jié)構(gòu)簡單(通常只有一個(gè)匹配電感)，卻具有重要作用。相同型號的清洗機(jī)，匹配調(diào)得好的清洗效果好；匹配調(diào)得差的則清洗效果差。對同一臺機(jī)器而言，如果工作一段時(shí)間后清洗效果變差，或者換能器經(jīng)過更換，都需要重新調(diào)整匹配。與一般電子設(shè)備的匹配有所不同，超聲清洗機(jī)的匹配除了要解決變阻問題(即變換負(fù)載的阻值，使之與發(fā)生器的負(fù)載值相等)外，還要解決調(diào)諧問題，即用匹配電感的感抗抵消換能器的容抗，使換能器呈純阻性。

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.

技術(shù)人員通常是根據(jù)各自的經(jīng)驗(yàn)進(jìn)行匹配。例如，有人在改變清洗槽水位時(shí)觀察電流的變化，如果電流變化處于一定范圍之內(nèi)，同時(shí)管子不發(fā)熱，空化聲強(qiáng)，便認(rèn)為匹配已調(diào)好。也有人讓機(jī)器空載時(shí)稍，微呈電感性，而在加載后轉(zhuǎn)變?yōu)榧冏锠顟B(tài)。這些經(jīng)驗(yàn)都是適用的。但在已有經(jīng)驗(yàn)的基礎(chǔ)上，再掌握匹配的原理，就可以在匹配時(shí)有的放矢，更加主動，從而收到事半功倍的效果。純水設(shè)備，超聲波洗機(jī)機(jī)，蘇州全自動超聲波清洗設(shè)備。蘇州超聲波清洗機(jī)，

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.
