在采购超声波清洗机的时候，是了解自己的产品可以用哪些方式去洗，第二是要达到一种什么样的清洁效果，第三是预计自己公司发展的产量会达到多少，要购买的机器产能是要多少，第四步是清洗工艺的了解，询问自己同行的是采用什么样的工艺，或者咨询超声波的生产厂家有没有更新的清洗工艺，第五是选择一些的生产企业进行清洗工艺、和售后服务保障方面比较，第六是在签订合同时把做设备所用材料型号，易耗品，维修条款等等写进合同协议中，以防一些不良生产企业的欺诈，第七是验收，如果是大型设备的话，您尽量要带上您的工件到生产企业去现场验收，第八是安装完对您公司员工的培训，您确定您的员工是真的学会了而不是安装人员所说已经培训过了。一、功率的选择

　　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

启航彩　　超声波清洗机有时用小功率，花费很长时间也没有污垢。而如果功率达到一定数值，很快便将污垢去除。若选择功率太大，空化强度将大大增加，清洗效果是提高了，但这时较精密的零件也产生了蚀点，而且清洗机底部振动板空化严重，水点腐蚀也增大，在采用三氯乙烯等有机溶剂时，基本上没有问题，但采用水或水溶性清洗液时，易于受到水点腐蚀，如果振动板表面已受到伤痕，强功率下水底产生空化腐蚀更严重，因此要按实际使用情况选择超声功率。二、频率的选择

启航彩　　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

　　超声清洗频率从28 kHz 到 120kHz 之间，在使用水或水清洗剂时由空穴作用引起的物理清洗力显然对低频有利，一般使用 28-40kHz 左右。对小间隙、狭缝、深孔的零件清洗，用高频(一般 40kHz 以上)较好，甚几百 kHz 。对钟表零件清洗时，用 100kHz 。若用宽带调频清洗，效果更良好。三、清洗篮的使用

　　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

　　在清洗小零件物品时，常使用网篮，由于网眼要引起超声衰减，要特别引起注意。当频率为 28khz 时使用 10mm 以上的网眼为好。

启航彩　　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.
