在采購(gòu)超聲波清洗機(jī)的時(shí)候，首先是了解自己的產(chǎn)品可以用哪些方式去洗，第二是要達(dá)到一種什么樣的清潔效果，第三是預(yù)計(jì)自己公司發(fā)展的產(chǎn)量會(huì)達(dá)到多少，要購(gòu)買(mǎi)的機(jī)器最大產(chǎn)能是要多少，第四步是清洗工藝的了解，詢(xún)問(wèn)自己同行的是采用什么樣的工藝，或者咨詢(xún)超聲波的生產(chǎn)廠(chǎng)家有沒(méi)有更新的清洗工藝，第五是選擇一些專(zhuān)業(yè)的生產(chǎn)企業(yè)進(jìn)行清洗工藝、價(jià)格和售后服務(wù)保障方面比較，第六是在簽訂合同時(shí)把做設(shè)備所用材料品牌型號(hào)，易耗品價(jià)格，維修條款等等寫(xiě)進(jìn)合同協(xié)議中，以防一些不良生產(chǎn)企業(yè)的欺詐，第七是驗(yàn)收，如果是大型設(shè)備的話(huà)，您盡量要帶上您的工件到生產(chǎn)企業(yè)去現(xiàn)場(chǎng)驗(yàn)收，第八是安裝完對(duì)您公司員工的培訓(xùn)，您確定您的員工是真的學(xué)會(huì)了而不是安裝人員所說(shuō)已經(jīng)培訓(xùn)過(guò)了。一、功率的選擇

　　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

　　超聲波清洗機(jī)有時(shí)用小功率，花費(fèi)很長(zhǎng)時(shí)間也沒(méi)有清除污垢。而如果功率達(dá)到一定數(shù)值，很快便將污垢去除。若選擇功率太大，空化強(qiáng)度將大大增加，清洗效果是提高了，但這時(shí)較精密的零件也產(chǎn)生了蝕點(diǎn)，而且清洗機(jī)底部振動(dòng)板空化嚴(yán)重，水點(diǎn)腐蝕也增大，在采用三氯乙烯等有機(jī)溶劑時(shí)，基本上沒(méi)有問(wèn)題，但采用水或水溶性清洗液時(shí)，易于受到水點(diǎn)腐蝕，如果振動(dòng)板表面已受到傷痕，強(qiáng)功率下水底產(chǎn)生空化腐蝕更嚴(yán)重，因此要按實(shí)際使用情況選擇超聲功率。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

　　超聲清洗頻率從28 kHz 到 120kHz 之間，在使用水或水清洗劑時(shí)由空穴作用引起的物理清洗力顯然對(duì)低頻有利，一般使用 28-40kHz 左右。對(duì)小間隙、狹縫、深孔的零件清洗，用高頻(一般 40kHz 以上)較好，甚至幾百 kHz 。對(duì)鐘表零件清洗時(shí)，用 100kHz 。若用寬帶調(diào)頻清洗，效果更良好。三、清洗籃的使用

　　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

　　在清洗小零件物品時(shí)，常使用網(wǎng)籃，由于網(wǎng)眼要引起超聲衰減，要特別引起注意。當(dāng)頻率為 28khz 時(shí)使用 10mm 以上的網(wǎng)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.
