由于超聲波清洗的原理是空化效應(yīng)，所以其性能驗(yàn)證主要是驗(yàn)證空化效應(yīng)，目的是看清洗槽內(nèi)聲場(chǎng)強(qiáng)度是否存在盲區(qū)。

Because the principle of ultrasonic cleaning is cavitation effect, its performance verification is mainly to verify the cavitation effect, the purpose is to see whether there is a blind area in the intensity of the sound field in the cleaning tank.

1、我們可以用鋁箔腐蝕方法進(jìn)行超聲波清洗機(jī)性能驗(yàn)證，將20-30微米厚的鋁箔紙放在支架上，垂直放置在清洗槽內(nèi)，不要碰到底部。機(jī)器啟動(dòng)一段時(shí)間后，鋁箔表面不同部位的腐蝕程度可以間接反映出超聲波強(qiáng)度的深度是否均勻。

1. We can use the aluminum foil corrosion method to verify the performance of the ultrasonic cleaning machine. Put the 20-30 micron thick aluminum foil on the bracket and vertically place it in the cleaning tank without touching the bottom. After the machine starts for a period of time, the corrosion degree of different parts on the aluminum foil surface can indirectly reflect whether the depth of ultrasonic intensity is uniform.

2. 

2、如果要檢測(cè)超聲波在水平方向上的強(qiáng)度分布，可以將鋁箔水平放置。該方法直觀、簡(jiǎn)便，但不能定量檢測(cè)，誤差較大。在裝填設(shè)備的條件下難以進(jìn)行試驗(yàn)，可能與堿性清洗劑發(fā)生化學(xué)反應(yīng)。

2. If the intensity distribution of ultrasonic wave in horizontal direction is to be detected, the aluminum foil can be placed horizontally. The method is intuitive and simple, but it can't be used for quantitative detection, and the error is large. It is difficult to carry out the test under the condition of loading equipment, and may react with alkaline detergent.

3、也可以用滑動(dòng)沖洗法驗(yàn)證，每周用HB鉛筆涂玻片，3分鐘內(nèi)用超聲波清洗干凈。記錄結(jié)果。該方法操作簡(jiǎn)單，但不能定量檢測(cè)，誤差較大。

3. It can also be verified by sliding washing method. Smear the slide with HB pencil every week and clean it with ultrasonic wave within 3 minutes. Record the results. This method is simple to operate, but it can't detect quantitatively, and the error is large.

4、或者是用淀粉碘化鉀反應(yīng)方法超聲波清洗機(jī)性能驗(yàn)證。將淀粉處理成光敏乳劑，涂在載玻片上，置于含有稀釋碘溶液的超聲波容器中。在超聲空化作用下，碘和淀粉發(fā)生反應(yīng)變成藍(lán)色，導(dǎo)致玻片變色。對(duì)玻片進(jìn)行沖洗干燥，通過對(duì)玻片變色區(qū)域的觀察，推斷出聲場(chǎng)的分布。該方法可以彌補(bǔ)鋁箔腐蝕法中鋁箔損傷的缺陷，但不能進(jìn)行定量檢測(cè)。

4. Or starch potassium iodide reaction method is used to verify the performance of ultrasonic cleaning machine. Starch was treated into photosensitive emulsion, coated on glass slide and placed in ultrasonic container containing diluted iodine solution. Under the action of ultrasonic cavitation, iodine reacts with starch and turns blue, resulting in the discoloration of glass slide. The slide was washed and dried, and the distribution of sound field was deduced by observing the discoloration area of the slide. This method can make up for the defect of aluminum foil damage in aluminum foil corrosion method, but it can not be used for quantitative detection.

5、染色法也是驗(yàn)證超聲波清洗機(jī)性能的方法之一，水分配染料，超聲波將涂在水中，超聲空化作用下，染料會(huì)附著在紙上，取出紙沖洗干燥。觀察染料模式的背景，對(duì)聲場(chǎng)的分布，如果不均勻分布的涂層，聲場(chǎng)不均勻，如寒冷的地方。

5. Dyeing method is also one of the methods to verify the performance of ultrasonic cleaning machine. The dye is distributed by water and applied by ultrasonic wave. Under the action of ultrasonic cavitation, the dye will adhere to the paper and take out the paper for washing and drying. Observe the background of the dye mode, the distribution of the sound field, if the uneven distribution of the coating, the sound field is uneven, such as cold places.

6、超聲波能量瓶試驗(yàn)超聲波清洗機(jī)性能驗(yàn)證的時(shí)候，所需變色時(shí)間與超聲空化能力成正比。根據(jù)水箱容積，將測(cè)能瓶置于不同位置，觀察換色時(shí)間。該方法直觀、簡(jiǎn)便，而且是定性測(cè)量。

6. When the ultrasonic energy bottle test is used to verify the performance of the ultrasonic cleaning machine, the required discoloration time is directly proportional to the ultrasonic cavitation ability. According to the volume of the water tank, put the energy measuring bottle in different positions and observe the color change time. The method is intuitive, simple and qualitative.
