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; Glasses, gear frame, 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.高壓清洗機的清洗范圍更廣。它采用電機或燃油發動機驅動高壓泵產生壓力，可根據不同的用途選擇不同的壓力。高壓清洗設備更廣泛地應用于生產領域和公共場所的清洗和維護。可用于清洗各種攪拌設備、運輸工具等物品，可疏通各種管道；可對鉆機平臺、輸油管道、油箱內外進行清潔；工廠地面和墻壁上的油污和水垢；可清潔建筑外墻、玻璃幕墻、鍋爐房、公共場所、停車場；在清潔服務行業，它可以用于清潔停車場、廣場、道路、街道等。它與超聲波清洗機的區別在于它可以清潔長的地下管道，大面積物體或大地方。

2. The cleaning range of high-pressure cleaning machine is wider. It uses the 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; It can clean the inside and outside of drilling 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. The difference between it and ultrasonic cleaning machine is that it can clean long underground pipelines, large areas of objects or large places.

第二：工作原理不同

Second: different working principles

1.超聲波清洗機主要利用超聲波的空化效應，在工件周圍形成巨大的沖擊力，使工件表面和縫隙上的污垢迅速剝離，從而達到工件表面凈化的目的。該清洗方法使復雜、彎曲、小型工件的清洗方便可行，易于實現自動化操作。由于清洗介質-水含有少量空氣，在初次清洗或更換清洗介質后的一段時間內，超聲波清洗機的超聲波效果會減弱，但隨著清洗時間的延長，水中的空氣會減少，即，當“冷水”變成“熱水”后，超聲波清洗效果將顯著提高。超聲波清洗的佳溫度為40℃-60℃。影響工件清洗效果的因素很多，包括頻率、功率、水質、清洗溫度、清洗時間長度、清洗劑的組成、清洗液的更換周期、壓縮空氣（鼓泡）質量、環境空氣質量、清洗槽中工件的放置姿勢和數量。

1. Ultrasonic cleaning machine mainly uses the cavitation effect of ultrasonic to form a huge impact force around the workpiece, so that the dirt on the workpiece surface and gap can be stripped quickly, 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 cleaning effect of workpieces, including frequency, power, water quality, cleaning temperature, cleaning time, composition of cleaning agent, replacement cycle of cleaning fluid, compressed air (bubbling) quality, ambient air quality, and the placement posture and quantity of workpieces in the cleaning tank.

2.高壓清洗是指高壓泵在驅動電機的作用下產生的高壓水射流，由高壓噴槍噴射到被清洗物體上，高壓噴嘴的孔徑遠小于高壓管道的直徑。因此，到達高壓噴嘴的水必須加速通過噴嘴。這樣，噴嘴就可以將高壓低流量的水變成低壓高流量的射流；高壓噴淋清洗主要是通過提高水壓對工件表面進行噴淋清洗，從而去除污垢。該方法實施簡單，操作方便，效果好，適用于平面工件。除污、除油、除銹效果明顯。大多數高壓清洗機使用一組閥門和泵頭來控制高壓水射流，使高壓清洗操作簡單

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. It 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：性能和用途的差異

Third: differences in performance and use

1.超聲波清洗是指去除被清洗物體表面的液體污垢和固體污垢，使其表面達到相應的清潔度清潔。其清洗過程是一個復雜的物理和化學過程。它的清洗不僅與污染物的性質、類型、形式和附著程度有關，還與溫度、壓力、附加超聲振動、機械外力等清洗條件有關。超聲波清洗利用液體中氣泡破裂產生的沖擊波來清潔和沖刷工件的內外表面。例如，超聲波洗碗機不需要電機或水泵，清洗時不需要高壓水和循環水。一切都是靠水分子的無聲振動來完成的，所以清洗機的噪音相對較小，省水省電

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, external mechanical 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.高壓清洗設備采用高壓水射流清洗技術。只要能將水射流直接引至該位置，無論是管道和容器的內腔，還是機械設備的表面，無論是堅硬頑固的結垢還是嚴重堵塞，都可以用高壓水射流徹底清洗。這種高壓清洗方法對材料特性有很大影響，對污垢的形狀和類型沒有特殊要求。只要能直接接觸到空氣，自動化程度高，清潔效果好，工作效率高，不污染自然環境。

2. High pressure cleaning equipment adopts high-pressure water jet cleaning technology. 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 no pollution to the natural environment.
