1. It can be identified from the production process and appearance of ultrasonic vibration plates

因为这直接体现了公司对产物质量的重视，技术和外观好的产物质量通常情况下自然不会差。而设计过程直接影响产物质量。

Because this directly reflects the company's emphasis on product quality, the quality of products with good technology and appearance is usually not inferior. The design process directly affects product quality.

2、可以根据超声波震板的工艺设计和使用的材料来识别

2. It can be identified based on the process design and materials used for ultrasonic vibration plates

但是这需要对换能器材料有很好的理解和经验。设计是否合理应根据选用的材料来确定。材料的好坏直接影响产物的质量。如果同一规格的材料不同，质量会有很大差异。劣质材料是做不出好产物的。

But this requires a good understanding and experience of the transducer material. The rationality of the design should be determined based on the selected materials. The quality of materials directly affects the quality of products. If materials of the same specification are different, there will be significant differences in quality. Poor quality materials cannot produce good products.

3、上机实验：

3. Computer Experiment:

a、功率输出实验；可以检测换能器与电箱的匹配情况，同时可以反映电箱送出的换能器负载功率输出的大小，模带越大，工作效果越好，功率输出越强。 (电流的大小只能反映输出效率，不能反映器件的功率)。

a. Power output experiment; It can detect the matching between the transducer and the electrical box, and also reflect the size of the load power output of the transducer sent by the electrical box. The larger the mode band, the better the working effect, and the stronger the power output. The magnitude of the current can only reflect the output efficiency, not the power of the device.

产、稳定性试验(模拟老化试验)；带上设备额定负载检测电箱及换能器的功率输出稳定性。

b. Stability test (simulated aging test); Check the power output stability of the electrical box and transducer with the rated load of the equipment.

肠、过载运行试验；测试产物质量的稳定性和寿命。该测试只需在额定负载下连续运行8小时。

c. Overload operation test; Test the stability and lifespan of product quality. This test only needs to run continuously for 8 hours under rated load.

超声波震板挑选方法：

Method for selecting ultrasonic vibration plates:

1、选择多功率振荡器或大功率振荡器

1. Choose a multi-power oscillator or high-power oscillator

好品质的超声波震荡器，关键在于它所适用的行业和常用清洗工件的种类。这是选择采购主要原则和依据。但一般来说，在选择这类设备时，不要选择小功率设备，因为通常小功率清洗效率低，效果差，可以选择多功率振荡器或大功率振荡器。

The key to a high-quality ultrasonic oscillator lies in the industry it is suitable for and the types of commonly used cleaning workpieces. This is the main principle and basis for selecting procurement. But generally speaking, when choosing such devices, do not choose low-power devices because low-power cleaning efficiency is usually low and the effect is poor. You can choose multi-power oscillators or high-power oscillators.

2、注意频率范围不能太小

2. Note that the frequency range should not be too small

精密超声波振荡器的工作效果与其频率直接相关。通常这类设备的频率不高，所以通用设备一般工作在低赫兹。但是，在清洁特殊产物或结构缝隙时，需要高频率操作。所以在选购超声波振子时，要选择宽带振子，频率范围不要太窄。

The working effect of a precision ultrasonic oscillator is directly related to its frequency. Usually, the frequency of such devices is not high, so general-purpose devices generally operate at low hertz. However, when cleaning special products or structural gaps, high-frequency operations are required. So when choosing an ultrasonic oscillator, it is important to choose a broadband oscillator with a frequency range that is not too narrow.

3、注意设备温度范围不宜过小

3. Note that the temperature range of the equipment should not be too small

超声波清洗机的温度控制也很重要，它的温度范围也是选购时的重中之重。因为有些清洗剂需要高温或更高温度的环境才能产生气蚀，如果设备的温度范围太小，不容易发生气蚀，所以清洗效果很差。

The temperature control of the ultrasonic cleaning machine is also important, and its temperature range is also a top priority when purchasing. Because some cleaning agents require a high or higher temperature environment to produce cavitation, if the temperature range of the equipment is too small, cavitation is not easy to occur, so the cleaning effect is poor.

4、注意震板的耐腐蚀性能不能差

4. Note that the corrosion resistance of the shock plate should not be poor

超声波振子的振动板作用很大，其换能器深置其中。如果盖板的抗压能力差或抗腐蚀能力弱，势必会影响换能器与导电介质的关系。所以在选购超声波振子时，一定要注意振动板的耐腐蚀性和抗压性。

The vibrating plate of the ultrasonic oscillator has a great effect, and its transducer is deeply embedded in it. If the pressure resistance or corrosion resistance of the cover plate is poor, it will inevitably affect the relationship between the transducer and the conductive medium. So when choosing ultrasonic vibrators, it is important to pay attention to the corrosion resistance and compressive resistance of the vibration plate.
