At present, the country has entered the era of waste classification, which also indicates that people pay more and more attention to environmental protection and cleaning. High pressure cleaning machine is a new type of high-pressure cleaning equipment developed in recent years. It has the characteristics of high efficiency and environmental protection, and has a wide range of applications, covering most fields of industrial cleaning. Especially in the environment with higher and higher environmental protection requirements, high-pressure water cleaning machines such as zero emission environmental protection cleaning equipment have attracted more and more attention from major enterprises. However, there is a problem that puzzles everyone. What is the cleaning efficiency of high-pressure water cleaning machine? We made a comprehensive analysis.

高压清洗机的清洁效率不仅与高压水射流的密度和速度有关，而且与射流与物体的标称距离有关。这是因为高压水射流的速度和结构随着射流距离而变化，因此冲击物体的力随着目标距离的变化而变化。

The cleaning efficiency of high-pressure cleaning machine is related not only to the density and speed of high-pressure water jet, but also to the nominal distance between jet and object. This is because the velocity and structure of high-pressure water jet change with the jet distance, so the force of impacting the object changes with the target distance.

高压水射流对物体的实际影响不仅取决于射流的基本参数，还取决于喷嘴位置和靶距之间的距离。高压水射流的距离，即靶距，是指喷嘴到洁净物体的距离。它的大小对清洗效果有很大的影响。随着喷射距离的增加，高压水射流的扩散水平增加到一个干净的名义值，即喷射功率损失增加。当喷射距离减小时，单位时间的除垢面积也减小。因此，如果高压清洗机太大或太小，清洗效率会降低。

The actual influence of high-pressure water jet on the object depends not only on the basic parameters of the jet, but also on the distance between the nozzle position and the target distance. The distance of high-pressure water jet, that is, the target distance, refers to the distance from the nozzle to the clean object. Its size has a great influence on the cleaning effect. With the increase of jet distance, the diffusion level of high-pressure water jet increases to a clean nominal value, that is, the jet power loss increases. When the spraying distance decreases, the descaling area per unit time also decreases. Therefore, if the high-pressure cleaning machine is too large or too small, the cleaning efficiency will be reduced.

高压射流清洗物体的重要影响是高压射流携带动能的响和良好的清洁效果。喷管与喷嘴的距离越远，喷管的压力越小，因此喷管在喷管中通过蒸汽作用产生的气泡会在喷管流动时突然改变。然而，暂时的实验证明，在喷嘴与喷嘴的距离上，清洁效果更好。在正常情况下，清洁效果取决于喷管对水的影响。

The important influence of high-pressure jet cleaning objects is the sound of kinetic energy carried by high-pressure jet and good cleaning effect. The farther away the nozzle is from the nozzle, the smaller the pressure of the nozzle is. Therefore, the bubbles generated by the steam in the nozzle will change suddenly when the nozzle flows. However, temporary experiments have proved that the cleaning effect is better in the distance between the nozzle and the nozzle. Under normal circumstances, the cleaning effect depends on the impact of the nozzle on the water.

这将影响高压清洗机的清洗效率。它们充分利用压力和流量，将压力能转化为速度能、喷嘴设计和目标冲击力。因此，在购买高压水轮机时，每个人不仅要关心高压清洗机的压力，还要综合各种因素来选择合适的高压流量清洗装置。

This will affect the cleaning efficiency of the high-pressure cleaning machine. They make full use of pressure and flow to convert pressure energy into velocity energy, nozzle design and target impact force. Therefore, when purchasing high-pressure water turbine, everyone should not only care about the pressure of high-pressure washing machine, but also integrate various factors to select the appropriate high-pressure flow cleaning device.
