清（qīng）洗（xǐ）機由超聲波（bō）發生器（qì）和超聲波換能器組成，超聲波換能（néng）器是由壓電陶瓷材料製造（zào）的夾芯（xīn）式換能器，壓電陶瓷材料（liào）在交（jiāo）變電場的作用下會產生機械振動。 超聲波換能器常見問題：

　　The cleaning machine consists of an ultrasonic generator and an ultrasonic transducer. The ultrasonic transducer is a sandwich type transducer made of piezoelectric ceramic material, which generates mechanical vibration under the action of an alternating electric field. Common problems with ultrasonic transducers:

　　1."超聲波換能器受潮"一般用（yòng）兆歐表檢查和換能器相連接的插頭（tóu），檢查換能器正負極間的絕緣（yuán）電阻值就可以判斷。一般要求（qiú）絕緣（yuán）電阻大於30兆歐以上。如果（guǒ）達不到這個絕緣電阻值，很可能是（shì）換能器受潮。維修方法是（shì）把換能器整體（不包括（kuò）噴塑（sù）外殼（ké））放（fàng）進烘箱設定100℃左右，烘幹三小時或者使用（yòng）電吹風去潮至阻值正常為止。換（huàn）能器振子打（dǎ）火，陶瓷材料碎裂。維修時可以（yǐ）用肉眼和兆（zhào）歐表結合檢查。一般作為應急處理的措施，可以把個別損壞的換能器斷開，不會影響到別的（de）換能器正常使用。

　　1. "Ultrasonic transducers are damp". Generally, a megohmmeter is used to check the plug connected to the transducer, and the insulation resistance value between the positive and negative poles of the transducer can be checked to determine. Generally, it is required that the insulation resistance be greater than 30 megaohms or above. If the insulation resistance value cannot be reached, it is likely that the transducer is damp. The maintenance method is to place the entire transducer (excluding the spray coated casing) in an oven set at around 100 ℃, dry for three hours or use a hair dryer to remove moisture until the resistance value is normal. The transducer oscillator ignites, causing the ceramic material to shatter. During maintenance, a combination of visual inspection and a megohmmeter can be used for inspection. As a general emergency measure, individual damaged transducers can be disconnected without affecting the normal use of other transducers.

　　2."換能器脫膠"91污（men）知道（dào）大多數廠家采用膠粘的方式固定換（huàn）能器，但超聲（shēng）波清洗機的長期使（shǐ）用後由（yóu）於振動會出現脫膠現象。也有廠（chǎng）家采用膠結加螺釘緊固的方式，一般情（qíng）況下不會出現脫膠，由於螺（luó）釘的作用，振（zhèn）子脫膠後不會從振動麵上落下，一般的判（pàn）斷（duàn）方法是用手輕（qīng）搖振子的尾部，仔細觀察振動（dòng）麵的膠（jiāo）水情（qíng）況做出判斷。

　　We know that most manufacturers use adhesive to fix the transducer, but ultrasonic cleaning machines may experience delamination due to vibration after long-term use. Some manufacturers also use the method of bonding and fastening with screws, which generally does not cause delamination. Due to the action of the screws, the oscillator will not fall off the vibration surface after delamination. The general judgment method is to gently shake the tail of the oscillator by hand and carefully observe the glue situation on the vibration surface to make a judgment.

　　3.一般振子出現脫膠以後超（chāo）聲波電源輸出的功率正常，但是由於振子與振動麵連接不好，振動麵的振動效果不（bú）好，長時間後由於能量無法釋放出去，很可能會燒壞振（zhèn）子。振子脫膠對於用戶來說維修起來是比較麻煩的，一般情況隻能送回生產廠家進行維修處理。避免振子（zǐ）脫膠（jiāo）最有效的方法是（shì）平時使用中注意不撞（zhuàng）擊振（zhèn）動麵。

　　3. Generally, after the detachment of the oscillator, the output power of the ultrasonic power supply is normal. However, due to poor connection between the oscillator and the vibration surface, the vibration effect of the vibration surface is not good. After a long time, the energy cannot be released, and it is likely to burn out the oscillator. The detachment of the oscillator is quite troublesome for users to repair, and in general, it can only be sent back to the manufacturer for repair and treatment. The most effective way to avoid detachment of the oscillator is to be careful not to hit the vibrating surface during normal use.

　　4."振動麵穿孔"一般超聲（shēng）波換能器滿負（fù）荷使用數年以（yǐ）後可（kě）能會出現振動麵穿（chuān）孔（kǒng）的情況，這是由於振動麵的不鏽鋼板長時間高頻振動疲（pí）勞所致，振動（dòng）麵穿孔說明換能（néng）器的使用壽命已經到了，維修上一般隻能更換。

　　4. "Perforation of vibration surface" Generally, ultrasonic transducers may experience perforation of vibration surface after several years of full load use, which is caused by long-term high-frequency vibration fatigue of the stainless steel plate on the vibration surface. Perforation of vibration surface indicates that the service life of the transducer has reached its end, and maintenance usually only requires replacement.

　　超聲波清洗機發生（shēng）器常見（jiàn）問題有：

　　Common problems with ultrasonic cleaning machine generators include:

　　1.超聲波清洗（xǐ）機打開電源開關，指示燈（dēng）不亮。這種情況維修時必須檢查電源開關是否完好，漏電開關是否合上。如果開關（guān）完好再檢（jiǎn）查保險（xiǎn）絲是否過載熔斷，基本上可以解決。

　　1. Turn on the power switch of the ultrasonic cleaning machine, but the indicator light does not light up. When repairing this situation, it is necessary to check whether the power switch is intact and whether the leakage switch is closed. If the switch is intact, checking if the fuse is overloaded and blown can basically solve the problem.

　　2.打開（kāi）電源（yuán）開關後，指示燈亮（liàng），但沒有超聲波輸出。這種情況比較複雜，維修時首先檢查換能器與超聲波功率板的連接插頭是否有鬆脫，然後（hòu）檢查保險絲是否熔斷。如果一切正常有可（kě）能是超聲功率發生器內部故障，用萬用表打電源線明線，火線是否都通。在（zài）排除了發生器故障後再檢查超聲波換（huàn）能器是否（fǒu）燒壞（huài），是否需要更換。

　　After turning on the power switch, the indicator light is on, but there is no ultrasonic output. This situation is quite complicated. When repairing, first check if the connection plug between the transducer and the ultrasonic power board is loose, and then check if the fuse is blown. If everything is normal, it is possible that there is an internal fault in the ultrasonic power generator. Use a multimeter to connect the power cord to the open wire and check if all live wires are connected. After troubleshooting the generator, check if the ultrasonic transducer is burnt out and if it needs to be replaced.

　　3.超聲波清洗機直流保險絲熔斷。可能是整流橋堆或功（gōng）率管燒毀，也可能是換能器老化，電流不穩，這些都可能造成電（diàn）源（yuán）發生器故障。維修時要多（duō）加注意。

　　3. The DC fuse of the ultrasonic cleaning machine is blown. It may be due to the burnout of rectifier bridge stack or power tube, or it may be due to the aging of transducer and unstable current, all of which can cause power generator failure. Pay more attention during maintenance.

　　4.超聲波清洗機打開電源開關後，機器有（yǒu）超（chāo）聲波輸出，但清洗效（xiào）果不如以前理想。這種情況（kuàng）大多是使用（yòng）不當造成，比如，清洗槽內清洗液液位不當，過高（gāo）或者過低；超聲波頻率（lǜ）協（xié）調沒有調好；清洗槽內液體溫度過高或過低；清洗液選用不（bú）當或者用量不夠。當然，也不排除（chú）換能器脫膠後使（shǐ）大部（bù）分超聲波能量無法傳遞到清洗液中（zhōng），這種情況應當及時送回廠（chǎng）家維修，以（yǐ）免燒壞振子。

　　After turning on the power switch of the ultrasonic cleaning machine, the machine has ultrasonic output, but the cleaning effect is not as ideal as before. This situation is mostly caused by improper use, for example, the level of cleaning solution in the cleaning tank is inappropriate, too high or too low; The ultrasound frequency coordination is not properly adjusted; The liquid temperature in the cleaning tank is too high or too low; Improper selection or insufficient use of cleaning solution. Of course, it cannot be ruled out that after the transducer is detached, most of the ultrasonic energy cannot be transmitted to the cleaning solution. In this case, it should be promptly sent back to the manufacturer for repair to avoid burning out the oscillator.
