高压清洗机在铝板带清洗设备上的应用近年来随着我国国民经济的高速发展，航空航天、家用电器、装饰材料及饮料行业等对铝带、箔的需求越来越大，带来了PS基材、铝塑带、电容器箔、制罐料等高精度铝板带材的快速发展。这些产品对平直度、洁净度要求非常严格，而高精度铝带材通常是采用全油冷却润滑轧制的，其表面残留大量的轧制油和铝粉，因此要获得良好的表面质量，必须清洗去掉其表面残留物。另外对于板形要求较高铝带材还要进行拉弯矫直，拉弯矫直使带材在拉仲和弯曲的作用下，逐步产生塑性延仲并释放板材内应力，以改善板带材在冷加工时产生的波形、翘曲、侧弯和潜在的板形不良等缺陷，从矫直工艺考虑，必须对带材表面进行清洗。
With the rapid development of China's national economy in recent years, the application of high pressure cleaning machine to aluminum strip cleaning equipment has developed rapidly. The demand for aluminum strip and foil is becoming more and more important in aerospace, household appliances, decorative materials and beverage industry. It has brought the rapid development of high precision aluminum strip such as PS base material, aluminum plastic belt, capacitor foil and tank material. These products are very strict for flatness and cleanliness, and high precision aluminum strip is usually rolled by full oil cooling, and its surface remains a large amount of rolled oil and aluminum powder. Therefore, to get good surface quality, it must be cleaned to remove the surface residue. In addition, it is necessary to straighten the strip with higher requirements and make the strip straighten and straighten and straighten the strip under the action of pulling and bending, and gradually producing the plastic extension and releasing the internal stress of the plate, so as to improve the wave, warpage, side bending and the potential bad shape of the plate in cold processing. First, the surface of the strip must be cleaned.
高压水射流的喷射距离高压水射流是靠密实的流束直接喷射而产生巨大的打击力，密实射流和直接喷射二者缺一不可。射流流束以喷嘴中心线呈对称布置，而是发散分布，射流一般分为三段。原始段，长度用L，表示，这段射流的特点是沿轴向的动压力值儿乎是常数，射流尖端的动压和喷嘴出口的动压是相同的。
The high pressure water jet of high pressure water jet is directly ejected by the dense flow beam, and the dense jets and direct jet two are indispensable. The jet flow is symmetrical in the center line of the nozzle, but diverges and distributes. The jet is generally divided into three segments. The original section, with the length of L, indicates that the jet is characterized by constant axial dynamic pressure, and the dynamic pressure of the jet tip is the same as the dynamic pressure of the nozzle exit.

另一特点质地非常密实，质点儿乎不和空气相混和，因此该段的打击力较强，主要用于清洗坚硬的结垢物，基本段，长度用Lz表示，这段射流的特点是空气开始与水射流相混合，形成了空穴和涡流，因此该段的打击力适中，适合各种设备及物料的清洗。
The other feature is very dense, and the particle is not mixed with air, so it has the strongest strike force. It is mainly used to clean hard dirt, the basic section, and the length is Lz. The jet is characterized by the air starting to mix with the water jet, forming holes and vortices, so the strike force is moderate and suitable for the section. Cleaning of all kinds of equipment and materials.
应该指出的是随着该段距离的加长，有效打击力也逐渐下降。发散段，长度用L3表示，这段射流的特点是空气与水射流完全混合，射流完全雾化，冲击压力和射流速度都大幅度下降，在技术上此段射流已没有应用价值。对于水射流清洗应用，关键在于压力和流量的选择与匹配。但在射流的不同喷射距离和扩散角上，起直接作用的压力和流量是不同的，另外受喷嘴结构性能差异的影响，即便在同样的出口压力和流量条件下，动压在量的分布上也有着较大的差异。可见，喷嘴的选用是不容忽视的关键环节。此外，射流断面形状与流量分布也是影响清洗效果的重要因素。
It should be noted that with the lengthening of the distance, the effective strike force will also gradually decline. The length of the divergent section is expressed in L3. The jet is characterized by a complete mixture of air and water jet. The jet is completely atomized and the impact pressure and the jet velocity are greatly reduced. The jet has no application value in technology. The key to the application of water jet cleaning is the selection and matching of pressure and flow. But in the different jet distance and diffusion angle of the jet, the pressure and flow of direct action are different. In addition, influenced by the difference of the structure and performance of the nozzle, even under the same outlet pressure and flow condition, the distribution of dynamic pressure varies greatly. It can be seen that the selection of nozzles is a key link that can not be ignored. In addition, the shape and discharge distribution of the jet section are also important factors affecting the cleaning effect.
