超聲波清洗機(jī)有電源，有超聲，超聲聲音很不正常，超聲力度不佳。這是怎么回事？下面通過(guò)式噴淋清洗機(jī)廠家為您講解這個(gè)問(wèn)題。

The ultrasonic cleaning machine has power supply and ultrasound. The ultrasonic sound is very abnormal and the intensity of ultrasound is poor. What's the matter? The manufacturer of the pass-through spray cleaner will explain this problem to you.

〔1〕用頻率表查看輸出頻率是否在換能器工作頻率范圍內(nèi)（頻率28KHZ換能器應(yīng)該在27KHZ-31KHZ，40KHZ換能器為38KHZ-42KHZ）。如果差別太大，可通過(guò)調(diào)節(jié)頻率電位器來(lái)恢復(fù)正常的工作頻率。

〔1〕 Use the frequency meter to check whether the output frequency is within the working frequency range of the transducer (the frequency of 28KHZ transducer should be 27KHZ-31KHZ, and that of 40KHZ transducer should be 38KHZ-42KHZ). If the difference is too large, the normal working frequency can be restored by adjusting the frequency potentiometer.

（2）觀察電流表的電流大小，如果電流比額定電流過(guò)小，應(yīng)檢查超聲波換能器是否有損壞，例如換能器脫落，換能器晶片破裂，粘結(jié)膠水開(kāi)裂等，連接導(dǎo)線是否有短路等。一般情況下，如果電流下降不多或根本沒(méi)有下降，而聲音又正常，但是超聲強(qiáng)度下降比較厲害，則很可能是換能器粘結(jié)膠水開(kāi)裂，其判斷方法為；觀察換能器與鋼板連接處的膠水涂層，正常情況下應(yīng)該是光滑的表面，如有細(xì)小裂痕則很可能是膠水已開(kāi)裂，此時(shí)應(yīng)該把換能器取下重新粘結(jié)，如電流下降比較厲害，則主要檢查是否有連接導(dǎo)線斷路或換能器晶片開(kāi)裂。

(2) Observe the current of the ammeter. If the current is too small than the rated current, first check whether the ultrasonic transducer is damaged, for example, the transducer falls off, the transducer chip is broken, the adhesive is cracked, and the connecting wire is short circuited. In general, if the current drops little or no at all, and the sound is normal, but the ultrasonic intensity drops sharply, it is likely that the adhesive of the transducer is cracked, and the judgment method is as follows:; Observe the glue coating at the connection between the transducer and the steel plate. It should be a smooth surface under normal conditions. If there is a small crack, it is likely that the glue has cracked. At this time, the transducer should be removed and re-bonded. If the current drop is severe, the main check is whether there is an open circuit in the connecting wire or a crack in the transducer chip.

（3）一般工作電壓，清洗對(duì)象，水溫高低及清洗液的種類等都會(huì)對(duì)超聲強(qiáng)度有影響，特別是在劇烈攪動(dòng)時(shí)，超聲會(huì)減弱，數(shù)十秒鐘才能恢復(fù)，

(3) Generally, the working voltage, cleaning object, water temperature and the type of cleaning fluid will have an impact on the ultrasonic intensity, especially in the case of intense agitation, the ultrasonic will weaken and can only recover in tens of seconds,

（4）超聲波換能器常見(jiàn)問(wèn)題：超聲波振子受潮，可以用兆歐表檢查與換能器相連接的插頭，其中2腳為超聲波換能器的正極，3腳是換能器的負(fù)極而且與換能器的外殼相連。檢查，23腳間的絕緣電阻值就可以判斷基本情況，一般要求絕緣電阻大于30兆歐以上。如果達(dá)不到這個(gè)絕緣電阻值，一般是換能器受潮。

(4) Common problems of ultrasonic transducer: the ultrasonic vibrator is damp, and the plug connected to the transducer can be checked with a megohmmeter. Two pins are the positive pole of the ultrasonic transducer, and three pins are the negative pole of the transducer and are connected to the shell of the transducer. Check the insulation resistance value between the 23 pins to determine the basic situation. Generally, the insulation resistance is more than 30 megohm. If the insulation resistance value is not reached, the transducer is usually damp.
