The ultrasonic cleaning machine has good cleaning effect and simple operation. The sound heard by people is a signal with a frequency of 20-20000 Hz. The sound wave higher than 20000 Hz is called the ultrasonic cleaning machine. The transmission of the sound wave propagates longitudinally according to the sinusoidal curve and produces a large number of small bubbles. One reason is that the local tensile stress in the liquid forms a negative pressure. The reduction of the pressure makes the gas originally dissolved in the liquid supersaturated, and escapes from the liquid into small bubbles. The other reason is that the strong tensile stress "tears" the liquid into a cavity, which is called cavitation.

超（chāo）聲波清洗機從放大電路形式，可以采用線性放大電路（lù）和（hé）開關電源電路，大功率超聲波電源從轉換效率方麵考慮一般采（cǎi）用開關（guān）電源的電路（lù）形式。線性電（diàn）源也有它特有的應用範圍，它的優點是可以不嚴格要求電路匹配，允（yǔn）許工作頻率連續快速變化。從目前超聲業界的情況看，超聲波主要（yào）分為自激式和它激式電源;超聲波電源的（de）使用主要是要根據換能器功率的大小、頻率的高低、電容量去匹（pǐ）配就可以。功率較小的可以使用自激式，功率較大的建議使用它激式。

The ultrasonic cleaning machine can adopt linear amplification circuit and switching power supply circuit in the form of amplification circuit. The high-power ultrasonic power supply generally adopts the circuit form of switching power supply in terms of conversion efficiency. Linear power supply also has its unique application range. Its advantage is that it can not strictly require circuit matching and allow continuous and rapid change of working frequency. From the current situation of ultrasonic industry, ultrasonic is mainly divided into self-excited power supply and other excited power supply; The use of ultrasonic power supply is mainly to match according to the power, frequency and capacitance of the transducer. The self-excited type can be used for low power, and it is recommended to use the other excited type for high power.

超聲（shēng）波清洗機的使用方法

Application method of ultrasonic cleaning machine

1. 超聲波清洗機在進行（háng）操作時使用（yòng）的電源是采用三芯插座（zuò）(相線、零線（xiàn）、地線)。

1. The power supply used in the operation of the ultrasonic cleaning machine is a three core socket (phase line, zero line and ground line).

2. 超聲（shēng）波清洗機的清（qīng）洗槽內必須要加入清洗液或者是水，其清洗液或者是水的液麵不得低（dī）於清洗槽高度的三分（fèn）之二（èr）(位（wèi）置應於網籃上沿口平齊（qí）)。清洗時（shí），請根據不同的清洗要求，添加（jiā）洗滌劑，加（jiā）強清洗效（xiào）率，所有洗滌劑必須符合不（bú）腐蝕清洗機內槽、機體（tǐ）的要（yào）求（qiú）。

2. The cleaning tank of the ultrasonic cleaning machine must be filled with cleaning liquid or water, and the liquid level of the cleaning liquid or water shall not be less than two-thirds of the height of the cleaning tank (the position shall be flush along the opening on the net basket). When cleaning, please add detergent according to different cleaning requirements to strengthen the cleaning efficiency. All detergents must meet the requirements of not corroding the inner tank and body of the cleaning machine.

3. 超聲（shēng）波（bō）清洗機會將被清洗物質放入金屬框內，根據清洗物的積垢程度，在一定程（chéng）度（dù）上設定清洗時間，一般3-10分鍾，特（tè）別難清洗的物質，可適（shì）當延長（zhǎng）清洗時間。(嚴禁把被清洗物質直接放在清洗槽底使用)。

3. The ultrasonic cleaning opportunity puts the cleaned material into the metal frame, and sets the cleaning time to a certain extent according to the scale degree of the cleaned material, generally 3-10 minutes. For the material that is particularly difficult to clean, the cleaning time can be extended appropriately. (it is strictly prohibited to put the cleaned material directly at the bottom of the cleaning tank for use).
