高压清洗机作为一种高效环保的清洗设备，其工作原理基于流体力学和能量转换原理。该设备主要由动力驱动单元和增压泵两大核心部件构成，以普通自来水作为工作介质。

As an efficient and environmentally friendly cleaning equipment, the working principle of high-pressure cleaning machine is based on fluid mechanics and energy conversion principles. The device mainly consists of two core components: the power drive unit and the booster pump, using ordinary tap water as the working medium.

在工作过程中，动力驱动单元带动增压泵运转，通过连续的吸水-增压-排水循环，将常压水转化为高压低速水流（压力通常可达5-40MPa）。

During the working process, the power drive unit drives the booster pump to operate, converting normal pressure water into high-pressure low-speed water flow (usually up to 5-40MPa) through a continuous cycle of water absorption, boosting, and drainage.

这种高压水流通过特殊设计的管路系统输送至喷嘴处，由于喷嘴孔径（通常0.5-3mm）远小于管路直径，根据伯努利原理，水流在通过喷嘴时速度急剧提升，完成高压低速到低压高速（流速可达100-300m/s）的能量转换过程。

This high-pressure water flow is transported to the nozzle through a specially designed pipeline system. Due to the nozzle aperture (usually 0.5-3mm) being much smaller than the pipeline diameter, according to Bernoulli's principle, the velocity of the water flow increases sharply when passing through the nozzle, completing the energy conversion process from high pressure low speed to low pressure high speed (flow rate can reach 100-300m/s).

这种高速水射流产生的冲击力可以轻松超过绝大多数污垢与基体表面的结合力（通常在0.5-5MPa范围内），从而实现对污垢层的机械剥离和冲刷清除，达到高效清洁的目的。

The impact force generated by this high-speed water jet can easily exceed the bonding force between the vast majority of dirt and the substrate surface (usually in the range of 0.5-5MPa), thereby achieving mechanical peeling and flushing removal of the dirt layer, achieving efficient cleaning.

在应用范围方面，高压清洗机展现出广泛的适用性。几乎所有具有刚性表面的工业制品都可以采用该技术进行清洗，包括但不限于：机械加工后的金属零部件（如轴承、齿轮等精密部件）、汽车制造领域的各类配件（发动机缸体、轮毂等）、压铸成型的铝合金/锌合金零件、五金制品（紧固件、工具等）、大型钢结构件（桥梁构件、船舶部件），以及各类物流周转容器（塑料箱、金属箱等）。

In terms of application scope, high-pressure cleaning machines have demonstrated a wide range of applicability. Almost all industrial products with rigid surfaces can be cleaned using this technology, including but not limited to: machined metal parts (such as precision components such as bearings and gears), various accessories in the automotive manufacturing field (engine cylinder blocks, wheel hubs, etc.), die cast aluminum/zinc alloy parts, hardware products (fasteners, tools, etc.), large steel structural components (bridge components, ship components), and various logistics turnover containers (plastic boxes, metal boxes, etc.).

相比传统清洗方式，高压水射流清洗具有无可比拟的优势：不仅能彻底清除表面附着的切削液、抛光膏等顽固污渍，还可深入复杂型腔和细微缝隙，实现全方位清洁，且不会对工件基体造成损伤或产生二次污染。

Compared to traditional cleaning methods, high-pressure water jet cleaning has unparalleled advantages: it can not only thoroughly remove stubborn stains such as cutting fluid and polishing paste attached to the surface, but also penetrate into complex cavities and subtle gaps, achieving all-round cleaning without causing damage or secondary pollution to the workpiece substrate.

针对不同性质的污垢，高压清洗机可提供冷水/热水两种清洗模式。冷水高压清洗（水温10-30℃）适用于常规的灰尘、泥土、金属屑等物理性附着物的清除，具有能耗低、设备简单的特点。而热水高压清洗机（水温通常可达80-95℃）则通过结合高压水射流的机械冲击和热能的化学作用，可高效处理各类顽固污染物：高温能显著降低油脂、沥青等高粘度物质的粘附强度；促进化学品残留的分解；快速融化冰层和蜡质；对食品加工行业的蛋白质类污垢也有独特效果。

For different types of dirt, the high-pressure cleaning machine can provide two cleaning modes: cold water/hot water. Cold water high-pressure cleaning (water temperature 10-30 ℃) is suitable for removing physical attachments such as dust, soil, metal shavings, etc. It has the characteristics of low energy consumption and simple equipment. The hot water high-pressure cleaning machine (usually with a water temperature of 80-95 ℃) can efficiently treat various stubborn pollutants by combining the mechanical impact of high-pressure water jet and the chemical action of thermal energy. High temperature can significantly reduce the adhesion strength of high viscosity substances such as oil and asphalt; Promote the decomposition of chemical residues; Quickly melt ice and wax; It also has a unique effect on protein based dirt in the food processing industry.

这种热力-机械协同清洗方式特别适合石化、食品加工、交通运输等行业的特殊清洗需求，清洗效率可比冷水清洗提高30-50%。设备通常配备燃油或电加热系统，能精确控制水温以适应不同清洗要求。

This thermal mechanical collaborative cleaning method is particularly suitable for the special cleaning needs of industries such as petrochemicals, food processing, and transportation. The cleaning efficiency can be increased by 30-50% compared to cold water cleaning. The equipment is usually equipped with a fuel or electric heating system, which can accurately control the water temperature to meet different cleaning requirements.

现代高压清洗机还集成了多项智能化技术：变频调节系统可根据清洗对象自动优化压力参数；旋转喷嘴设计能产生三维清洗轨迹；废水回收装置实现环保作业；安全联锁系统确保操作防护。

Modern high-pressure cleaning machines also integrate multiple intelligent technologies: the variable frequency regulation system can automatically optimize pressure parameters according to the cleaning object; Rotating nozzle design can generate three-dimensional cleaning trajectories; Wastewater recycling equipment achieves environmentally friendly operations; The safety interlock system ensures operational protection.

这些技术创新使高压清洗技术在工业维护、市政清洁、食品加工等领域的应用不断拓展，成为绿色清洁生产的重要装备。随着环保要求的不断提高和清洗技术的持续进步，高压清洗设备正朝着更高压力、更智能化、更节能环保的方向发展，为各行业提供更加高效的清洁解决方案。

These technological innovations have continuously expanded the application of high-pressure cleaning technology in industrial maintenance, municipal cleaning, food processing and other fields, becoming an important equipment for green and clean production. With the continuous improvement of environmental protection requirements and the continuous advancement of cleaning technology, high-pressure cleaning equipment is developing towards higher pressure, intelligence, energy conservation and environmental protection, providing more efficient cleaning solutions for various industries.
