：使用范围的区别

First: differences in the scope of use

1.超声波清洗机主要用于机械工业行业。超声波可清洗机械零件、印刷电路板、真空管零件、硅片、电容器等；在精密工业中，超声波可以清洗仪器、仪表、钟表表盘和零件；齿轮、弹簧、眼镜架、金属饰物；在汽车行业，它可以清洗阀门、发动机缸、变速箱、燃油泵、活塞环等。总之，行业中有很多五金零件，电子机械，光学玻璃等等，只要能放入超声波清洗容器就可以用超声波清洗。

1. Ultrasonic cleaning machine is mainly used in machinery industry. Ultrasonic can clean mechanical parts, printed circuit boards, vacuum tube parts, silicon wafers, capacitors, etc; In precision industry, ultrasonic can clean instruments, meters, clocks, dials and parts; Gears, springs, spectacle frames, metal ornaments; In the automotive industry, it can clean valves, engine cylinders, gearboxes, fuel pumps, piston rings, etc. In short, there are many hardware parts, electronic machinery, optical glass and so on in the industry. As long as they can be put into the ultrasonic cleaning container, they can be cleaned with ultrasonic.

2.高压清洗机的清洗范围更广。它采用电机或燃油发动机驱动高压泵产生压力，可根据不同的用途选择不同的压力。高压清洗设备更广泛地应用于生产领域和公共场所的清洗和维护。可用于清洗各种搅拌设备、运输工具等物品，可疏通各种管道；可对钻机平台、输油管道、油箱内外进行清洁；工厂地面和墙壁上的油污和水垢；可清洁建筑外墙、玻璃幕墙、锅炉房、公共场所、停车场；在清洁服务行业，它可以用于清洁停车场、广场、道路、街道等。

2. The cleaning range of high-pressure cleaning machine is wider. It uses a motor or fuel engine to drive the high-pressure pump to generate pressure, and different pressures can be selected according to different purposes. High pressure cleaning equipment is more widely used in the cleaning and maintenance of production fields and public places. It can be used to clean all kinds of mixing equipment, transportation tools and other items, and dredge all kinds of pipelines; Clean the rig platform, oil pipeline and oil tank; Oil and scale on the factory floor and walls; It can clean building exterior walls, glass curtain walls, boiler rooms, public places and parking lots; In the cleaning service industry, it can be used to clean parking lots, squares, roads, streets, etc.

第二：工作原理不同

Second: the working principle is different

1.超声波清洗机主要利用超声波的空化效应，在工件周围形成巨大的冲击力，使工件表面和缝隙上的污垢迅速剥离，从而达到工件表面净化的目的。该清洗方法使复杂、弯曲、小型工件的清洗方便可行，易于实现自动化操作。由于清洗介质-水含有少量空气，在初次清洗或更换清洗介质后的一段时间内，超声波清洗机的超声波效果会减弱，但随着清洗时间的延长，水中的空气会减少，即，当“冷水”变成“热水”后，超声波清洗效果将显著提高。超声波清洗的佳温度为40℃-60℃。影响工件清洗效果的因素很多，包括频率、功率、水质、清洗温度、清洗时间长度、清洗剂的组成、清洗液的更换周期、压缩空气（鼓泡）质量、环境空气质量、清洗槽中工件的放置姿势和数量。

1. The ultrasonic cleaning machine mainly uses the cavitation effect of ultrasonic to form a huge impact force around the workpiece, so as to quickly peel off the dirt on the workpiece surface and gap, so as to achieve the purpose of workpiece surface purification. The cleaning method makes the cleaning of complex, curved and small workpieces convenient and feasible, and is easy to realize automatic operation. Because the cleaning medium water contains a small amount of air, the ultrasonic effect of the ultrasonic cleaning machine will be weakened in a period of time after the initial cleaning or replacement of the cleaning medium, but with the extension of the cleaning time, the air in the water will be reduced, that is, when the "cold water" becomes "hot water", the ultrasonic cleaning effect will be significantly improved. The optimum temperature for ultrasonic cleaning is 40 ℃ - 60 ℃. There are many factors affecting the workpiece cleaning effect, including frequency, power, water quality, cleaning temperature, cleaning time length, composition of cleaning agent, replacement cycle of cleaning fluid, compressed air (bubbling) quality, ambient air quality, and the placement position and quantity of workpieces in the cleaning tank.

2.高压清洗是指高压泵在驱动电机的作用下产生的高压水射流，由高压喷枪喷射到被清洗物体上，高压喷嘴的孔径远小于高压管道的直径。因此，到达高压喷嘴的水必须加速通过喷嘴。这样，喷嘴就可以将高压低流量的水变成低压高流量的射流；高压喷淋清洗主要是通过提高水压对工件表面进行喷淋清洗，从而去除污垢。该方法实施简单，操作方便，效果好，适用于平面工件。除污、除油、除锈效果明显。大多数高压清洗机使用一组阀门和泵头来控制高压水射流，使高压清洗操作简单

2. High pressure cleaning refers to the high-pressure water jet generated by the high-pressure pump under the action of the driving motor, which is sprayed onto the cleaned object by the high-pressure spray gun. The aperture of the high-pressure nozzle is much smaller than the diameter of the high-pressure pipe. Therefore, the water reaching the high-pressure nozzle must accelerate through the nozzle. In this way, the nozzle can turn the water with high pressure and low flow into a jet with low pressure and high flow; High pressure spray cleaning is mainly to spray clean the workpiece surface by increasing the water pressure, so as to remove dirt. The method has the advantages of simple implementation, convenient operation and good effect, and is suitable for plane workpieces. The effect of decontamination, oil removal and rust removal is obvious. Most high-pressure cleaning machines use a set of valves and pump heads to control the high-pressure water jet, making the high-pressure cleaning operation simple

第三：性能和用途的差异

Third: differences in performance and use

1.超声波清洗是指去除被清洗物体表面的液体污垢和固体污垢，使其表面达到相应的清洁度清洁。其清洗过程是一个复杂的物理和化学过程。它的清洗不仅与污染物的性质、类型、形式和附着程度有关，还与温度、压力、附加超声振动、机械外力等清洗条件有关。超声波清洗利用液体中气泡破裂产生的冲击波来清洁和冲刷工件的内外表面。例如，超声波洗碗机不需要电机或水泵，清洗时不需要高压水和循环水。一切都是靠水分子的无声振动来完成的，所以清洗机的噪音相对较小，省水省电

1. Ultrasonic cleaning refers to removing the liquid dirt and solid dirt on the surface of the cleaned object to make the surface reach the corresponding cleanliness. The cleaning process is a complex physical and chemical process. Its cleaning is not only related to the nature, type, form and adhesion degree of pollutants, but also related to the cleaning conditions such as temperature, pressure, additional ultrasonic vibration, mechanical external force and so on. Ultrasonic cleaning uses the shock wave generated by the rupture of bubbles in the liquid to clean and wash the inner and outer surfaces of the workpiece. For example, ultrasonic dishwashers do not require motors or pumps, and high-pressure water and circulating water are not required for cleaning. Everything is completed by the silent vibration of water molecules, so the noise of the cleaning machine is relatively small, saving water and electricity

2.高压清洗设备采用高压水射流清洗技术。只要能将水射流直接引至该位置，无论是管道和容器的内腔，还是机械设备的表面，无论是坚硬顽固的结垢还是严重堵塞，都可以用高压水射流彻底清洗。这种高压清洗方法对材料特性有很大影响，对污垢的形状和类型没有特殊要求。只要能直接接触到空气，自动化程度高，清洁效果好，工作效率高，不污染自然环境。

2. High pressure water jet cleaning technology is adopted for high-pressure cleaning equipment. As long as the water jet can be directly led to this position, whether it is the inner cavity of pipes and containers, or the surface of mechanical equipment, whether it is hard and stubborn scaling or serious blockage, it can be thoroughly cleaned with high-pressure water jet. This high-pressure cleaning method has a great impact on the material characteristics, and has no special requirements for the shape and type of dirt. As long as it can directly contact the air, it has high degree of automation, good cleaning effect, high work efficiency and does not pollute the natural environment.
