在采購超聲波清（qīng）洗機的時候（hòu），首先是了解自己的產品可以用哪些（xiē）方式（shì）去洗，第二是要達到（dào）一（yī）種什（shí）麽樣的清潔效果，第三是預計自己公司（sī）發展的產量會達到多（duō）少，要購買的機器最大產能是要多少，第四步是清洗工藝的（de）了解，詢問自己同行的是采用什麽樣的工藝，或者谘詢超聲波的生（shēng）產（chǎn）廠家有（yǒu）沒有更新的清洗工藝，第（dì）五（wǔ）是選擇一些專業的生產企業進行清洗工藝、價格和（hé）售後服務（wù）保障方麵比較，第六是在簽訂合同時把做設備所用材料品牌型號，易耗品價格，維（wéi）修條款等等寫進合（hé）同協議（yì）中，以防一些不良生產企業的欺詐，第七是驗收，如果是（shì）大型設備的話，您盡量要帶上（shàng）您的工件到（dào）生產企業去現場驗收，第八（bā）是安裝完對您公司員工的培訓，您確定您的（de）員工是真的學會了而不是安裝人（rén）員所說已經培訓過了（le）。一、功率的（de）選擇

　　When purchasing an ultrasonic cleaning machine, the first step is to understand how your product can be cleaned, the second is to achieve what kind of cleaning effect, the third is to estimate your company's production capacity and the maximum production capacity of the machine you want to purchase, the fourth step is to understand the cleaning process, ask your peers what kind of process they are using, or consult with ultrasonic manufacturers for updated cleaning processes, the fifth is to compare the cleaning process, price, and after-sales service guarantee of some professional production enterprises, and the sixth is to include the brand and model of materials used in the equipment, consumable prices, maintenance terms, etc. in the contract agreement when signing the contract, in order to prevent some bad production enterprises from being affected. Fraud, the seventh is acceptance. If it is a large equipment, You should try to bring your workpiece to the production enterprise for on-site inspection. The eighth step is to provide training to your company's employees after installation. Are you sure that your employees have truly learned it, rather than the installation personnel claiming that they have already been trained. 1、 Power selection

　　超聲（shēng）波清洗機有（yǒu）時用（yòng）小功率，花（huā）費很長時（shí）間也沒有清（qīng）除汙垢。而如果功率達到一定數值，很快便將汙垢去除。若（ruò）選擇功率太大，空化強度將大大增加，清洗效（xiào）果（guǒ）是提高了，但這時較精密的零件也產生了蝕點，而且清洗機底部振（zhèn）動板空化嚴重，水點腐蝕也增大，在采用三氯乙烯等有機溶劑時，基本上沒有問題（tí），但采用水或水溶性清洗液時，易於受到水點腐蝕，如果振（zhèn）動板表麵已受到傷（shāng）痕（hén），強功率（lǜ）下水底產（chǎn）生（shēng）空化腐蝕更嚴（yán）重，因此要按實際使用情況（kuàng）選擇超聲功率。二、頻率的選擇

　　Ultrasonic cleaning machines sometimes use low power and take a long time without removing dirt. If the power reaches a certain value, the dirt will be quickly removed. If the power is chosen to be too high, the cavitation intensity will be greatly increased, and the cleaning effect will be improved. However, at this time, more precise parts will also produce corrosion points, and the vibration plate at the bottom of the cleaning machine will have severe cavitation, and water point corrosion will also increase. When using organic solvents such as trichloroethylene, there is basically no problem, but when using water or water-soluble cleaning solutions, it is easy to suffer from water point corrosion. If the surface of the vibration plate has been damaged, cavitation corrosion will be more severe under high power, so the ultrasonic power should be selected according to the actual use situation. 2、 Frequency selection

　　超聲清洗頻（pín）率（lǜ）從28 kHz 到 120kHz 之間，在使用水或（huò）水清洗劑時由空穴作用引起的物理清洗力顯然對低頻有利，一般使用 28-40kHz 左右。對小間隙、狹縫、深孔的零（líng）件清洗，用高頻(一般 40kHz 以上)較好，甚至幾百 kHz 。對鍾表零件（jiàn）清洗時，用 100kHz 。若用寬帶調頻清洗，效果更良好。三、清洗籃的使（shǐ）用

　　The ultrasonic cleaning frequency ranges from 28 kHz to 120 kHz, and the physical cleaning force caused by the action of holes when using water or water cleaning agents is clearly advantageous for low frequencies. Generally, around 28-40 kHz is used. For cleaning parts with small gaps, narrow slits, and deep holes, it is better to use high frequency (usually above 40kHz), even several hundred kHz. When cleaning clock parts, use 100kHz. If broadband FM cleaning is used, the effect will be better. 3、 Use of cleaning basket

　　在清（qīng）洗小零件物（wù）品時，常使用網籃，由於網眼要引起超聲衰減，要特別引起注意。當頻率為 28khz 時使用 10mm 以上的網眼為好。

　　When cleaning small items, a mesh basket is often used, and special attention should be paid to the ultrasonic attenuation caused by the mesh. It is better to use a mesh size of 10mm or more when the frequency is 28kHz.
