喷淋清洗机的性能优劣，很大程度上取决于三大核心参数的匹配：压力、流量和喷嘴。

The performance of a spray cleaning machine largely depends on the matching of three core parameters: pressure, flow rate, and nozzle.

压力是清洗能力的决定性因素。压力越高，液流速度越快，冲击力越强。但并非压力越高越好。压力过高可能损伤工件表面；压力过低则清洗不有效。一般原则是：轻油污、精密件采用较低压力（0.5-1.0MPa）；重油污、厚重件采用较高压力（1.0-3.0MPa）。实际应用中可通过变频调节实现压力的准确控制。

Pressure is the decisive factor in cleaning ability. The higher the pressure, the faster the liquid flow velocity, and the stronger the impact force. But the higher the pressure, the better. Excessive pressure may damage the surface of the workpiece; If the pressure is too low, the cleaning will not be thorough. The general principle is to use lower pressure (0.5-1.0MPa) for light oil stains and precision parts; Heavy oil stains and heavy components are subjected to high pressure (1.0-3.0MPa). In practical applications, precise pressure control can be achieved through frequency conversion regulation.

流量决定了单位时间内有多少清洗液作用到工件表面。流量不足，即使压力再高，也无法形成有效的覆盖。流量过大则造成清洗液浪费。流量与压力的匹配需要根据喷嘴规格和清洗面积计算。一般建议：每个喷嘴的流量控制在2-5L/min范围内，通过增加喷嘴数量来提升总流量。

The flow rate determines how much cleaning solution is applied to the surface of the workpiece per unit time. Insufficient flow, even with high pressure, cannot form effective coverage. Excessive flow can cause waste of cleaning solution. The matching of flow rate and pressure needs to be calculated based on the nozzle specifications and cleaning area. General recommendation: Control the flow rate of each nozzle within the range of 2-5L/min and increase the total flow rate by increasing the number of nozzles.

喷嘴选择需综合考虑喷射角度、射流形状和材质。喷射角度决定覆盖范围——角度越大覆盖越广但冲击力分散；角度越小冲击力越集中但覆盖面积小。射流形状决定清洗方式——扇形适合平面；锥形适合点状污渍；旋转式适合复杂曲面。喷嘴材质影响耐用性——不锈钢喷嘴耐腐蚀；陶瓷喷嘴耐磨；硬质合金喷嘴适合高压高磨蚀工况。

The selection of nozzles should comprehensively consider the spray angle, jet shape, and material. The spray angle determines the coverage range - the larger the angle, the wider the coverage, but the impact force is dispersed; The smaller the angle, the more concentrated the impact force but with a smaller coverage area. The shape of the jet determines the cleaning method - fan-shaped is suitable for flat surfaces; Cone shape is suitable for spot stains; Rotating type is suitable for complex surfaces. The nozzle material affects durability - stainless steel nozzles are corrosion-resistant; Ceramic nozzle wear-resistant; Hard alloy nozzles are suitable for high-pressure and high abrasion conditions.

温度是常被忽视但影响显著的参数。提高清洗液温度能增强化学清洗剂的活性，加速油污的乳化和溶解。但温度过高会增加能耗，且可能使某些清洗剂分解或挥发。一般水基清洗剂的非常佳工作温度为50-70℃。采用蒸汽加热或电加热管配合智能温控系统，可准确控制温度并避免能源浪费。

Temperature is a parameter that is often overlooked but has a significant impact. Raising the temperature of the cleaning solution can enhance the activity of chemical cleaning agents, accelerate the emulsification and dissolution of oil stains. However, excessively high temperatures can increase energy consumption and may cause certain cleaning agents to decompose or evaporate. The optimal working temperature for general water-based cleaning agents is 50-70 ℃. By using steam heating or electric heating tubes in conjunction with an intelligent temperature control system, temperature can be accurately controlled and energy waste can be avoided.

过滤系统是保证清洗质量的隐形功臣。喷淋清洗过程中，剥离的污垢会混入清洗液。如果不及时过滤，这些污垢会随清洗液再次喷射到工件表面，造成二次污染。多级过滤装置（袋式过滤器、磁性过滤器等）可回收清洗液并去除杂质，实现清洗液的重复利用，降低耗材成本。

The filtration system is an invisible contributor to ensuring the quality of cleaning. During the spray cleaning process, the peeled dirt will mix into the cleaning solution. If not filtered in time, these dirt will be sprayed onto the surface of the workpiece again with the cleaning solution, causing secondary pollution. Multi stage filtration devices (bag filters, magnetic filters, etc.) can recycle cleaning solution and remove impurities, achieving the reuse of cleaning solution and reducing consumable costs.
