如果说超声波清洗时用声能强化清洗，使清洗技术向高功能化合专用型方向发展的话，那么目前相对应用推广的水射流清洗则是用机械能强化清洗，向高功能化发展的另一种类型。特别是高压水射流清洗时射流清洗技术的最新发展。水射流清洗对环境不构成污染，清洗效率高，清洗质量好，适应性强，能满足各类永华的特殊需要，特别是对大面积、大型工件的清洗更有其独到的优点。既可在清洗机械设备内清洗液可以在外部或现场清洗。根据清洗的工件大小和清洗污物类型的不同，清洗设备的用途，其清洗能力和机械化自动化水平和射流清洗方法的实施也是不同的，可采用各式各样的方法。水射流清洗的能力既与污物的牢固性和数量有关。也就是要求射流的动压强超过污物在表面的牢固性。牢固性代表了污物本身的内聚性和与表面的附着力有关。只要射流的动压强在污物区稍高于上述的牢固性能时，污物即可剥离并从表面脱落。因此，水射流清洗时利用水力喷枪在压力0.5~2.0MPa下将温度为90~100℃的汽水射流向被清洗的表面。由于射流的冲击作用与高温清洗液配合可有效地清洗工件表面上的油类及其分解物，润滑油和油封保护层及尘埃微粒等除油污的作用明显。但对腐蚀产物如铁锈、砂皮、水垢等和表面有化学作用的污物则清除不干净。
流体动力清洗的方法是向被清洗表面压送不同压力（0.5~20MPa）、温度为20~80℃的水流或洗涤剂流体。射流的动压力，高温和清洗剂的综合作用，能有效地清除表面的各种污物。

If the ultrasonic cleaning with acoustic energy intensive cleaning, the cleaning technology to the development of special function type combined direction, then the water jet cleaning the relative application is enhanced cleaning using mechanical energy, to another type of high functional development. Especially on the latest development of high pressure water jet cleaning jet cleaning technology. Water jet cleaning does not constitute pollution to the environment, high cleaning efficiency, good cleaning quality, strong adaptability, can meet the special needs of various Yonghua, especially cleaning more for large area, large parts of its unique advantages. Not only can the cleaning machinery and equipment cleaning fluid can be external or cleaning the scene. According to the size of the workpiece cleaning and cleaning dirt types, use cleaning equipment, the cleaning ability and level of mechanization and automation and jet cleaning method is different, can adopt every kind of method. The ability of water jet cleaning and dirt of the firm and the number of. Also is the request of dynamic pressure jet over the dirt in the solid surface. Firm represents the dirt itself cohesion and adhesion on the surface. As long as the jet dynamic pressure is higher than the strong performance of the slightly in the dirt area, dirt can be peeled and fall from the surface. Therefore, water jet cleaning with water gun under the 0.5~2.0MPa pressure temperature for 90~100 ℃ surface water shooting to be cleaned. As a result of impact jet with high temperature cleaning liquid and cleaning the oil to the surface of the work effectively and its decomposition products, lubricating oil and seal protection layer and dust particles and other degrease effect. But the dirt corrosion products such as rust, sand, scale and surface chemistry there is removed is not clean.
