1. It can be identified from the manufacturing process and appearance of the ultrasonic cleaner; It directly reflects the company's focus on production and quality. The production and quality with good technology and appearance will naturally be better (but not absolute). Moreover, the design process directly affects the production and quality.

2.可依据超声波清洗机的工艺设计和资料停止辨认，但需求对换能器资料有较好的理解和丰厚的经历。设计能否合理取决于资料的选择。资料的质量直接影响产品的质量。光版复制不一定可行。不同于相同规格资料的来源，质量也有很大差别。 （人员）

2. It can be identified according to the process design and data of ultrasonic cleaning machine, but it is required to have a good understanding and rich experience in the data of energy exchanger. Whether the design is reasonable or not depends on the selection of data. The quality of data directly affects the quality of products. Optical copy is not necessarily feasible. Different from the source of the same specification data, the quality is also very different. (professionals)

3.参数检测;检测传感器参数能否与电箱参数匹配，能否能到达理想效果。 （熟习设备参数的人士）

3. Parameter detection; Check whether the sensor parameters match the electric box parameters and whether the ideal effect can be achieved. (professionals familiar with equipment parameters)

4.车载测试：

4. On board test:

（1）功率输出测试;它能够检测传感器与电箱之间的匹配，并能反映电箱输出功率和传感器负载。模带的工作效果越大，功率输出越好。 （电流幅度仅反映输出效率，而非设备功率幅度）

(1) Power output test; It can detect the matching between the sensor and the electric box, and reflect the output power of the electric box and the sensor load. The greater the working effect of the die band, the better the power output. (current amplitude only reflects output efficiency, not equipment power amplitude)

（2）稳定性实验（模仿老化实验）;具有额定负载的测试箱和传感器的功率输出稳定性。

(2) Stability test (simulated aging test); Power output stability of test box and sensor with rated load.

（3）过载运转实验;测试产质量量的稳定性和寿命。该测试仅需求在额定负载下连续运转8小时。目前，没有这样的东西（我公司除外）。由于我们的产质量量差，我们经不起考验。测试在不到几非常钟内报废。但它仍可用于塑料焊接机约一年。自产品改良以来，该测试公司增加了产品。它直接反映了传感器的稳定性和寿命。因而，能够依据测试结果改良产质量量。在塑料焊接机上，能够接受此测试的传感器的短运用寿命可达五年以上（真正契合国际规范）。在超声波清洗机产品之前，只要美国产品才能达到它。

(3) Overload operation test; Test the stability and life of production and quality. The test only requires continuous operation for 8 hours under rated load. At present, there is no such thing in China (except our company). Because of our poor quality, we can't stand the test. The test was scrapped in less than ten minutes. But it can still be used in plastic welding machines for about a year. Since the product improvement, the testing company has increased its products. It directly reflects the stability and service life of the sensor. Therefore, the yield and quality can be improved according to the test results. On the plastic welding machine, the shortest service life of the sensor that can accept this test can reach more than five years (truly in line with international specifications). Before ultrasonic cleaning machine products, only American products can reach it.
