碳氢清洗机作为工业清洗领域的高效设备，其清洗流程经过精心设计，能够确保工件得到彻底清洁，同时实现碳氢溶剂的循环利用。了解这一流程，有助于更好地理解其工作原理和高效性的来源。

　　As an efficient equipment in the industrial cleaning field, the hydrocarbon cleaning machine has a carefully designed cleaning process that ensures thorough cleaning of the workpiece while achieving the recycling of hydrocarbon solvents. Understanding this process helps to better understand its working principle and the sources of efficiency.

　　清洗流程的第一步是工件预处理。在将工件放入清洗机之前，需要对其进行简单处理。操作人员会先清除工件表面附着的大块杂质，如金属碎屑、灰尘结块等，避免这些杂质进入清洗系统后污染溶剂或堵塞设备管路。对于带有复杂结构的工件，比如带有深孔、缝隙的零件，会检查是否有缠绕的丝线、残留的大块油污等，必要时进行手工初步清理，为后续的深度清洗做好准备。预处理虽简单，却能有效提高整体清洗效率，减少设备运行中的故障风险。

　　The first step in the cleaning process is workpiece pretreatment. Before placing the workpiece into the cleaning machine, it needs to be subjected to simple processing. The operator will first remove large impurities attached to the surface of the workpiece, such as metal debris, dust clumps, etc., to avoid these impurities entering the cleaning system and contaminating the solvent or blocking the equipment pipeline. For workpieces with complex structures, such as those with deep holes and gaps, they will be checked for tangled threads, residual large oil stains, etc. If necessary, manual preliminary cleaning will be carried out to prepare for subsequent deep cleaning. Although preprocessing is simple, it can effectively improve overall cleaning efficiency and reduce the risk of equipment failure during operation.

　　接下来进入核心的清洗阶段，这一阶段通常包含多个步骤，且会根据工件的污染程度和清洁要求进行调整。首先是浸泡清洗，将预处理后的工件放入装有碳氢溶剂的清洗槽中，让溶剂充分包裹工件。碳氢溶剂会逐渐渗透到油污内部，对其进行溶解，对于一些附着不牢固的油污，在浸泡过程中就会脱离工件表面。浸泡时间根据工件油污的厚度和性质而定，一般从几分钟到几十分钟不等。

　　Next, we enter the core cleaning stage, which usually involves multiple steps and will be adjusted according to the degree of contamination and cleaning requirements of the workpiece. Firstly, soak and clean the pre treated workpiece by placing it into a cleaning tank filled with hydrocarbon solvents, allowing the solvent to fully envelop the workpiece. Carbon hydrogen solvents will gradually penetrate into the oil stains and dissolve them. For some oil stains that are not firmly attached, they will detach from the surface of the workpiece during the soaking process. The soaking time depends on the thickness and nature of the oil stains on the workpiece, generally ranging from a few minutes to several tens of minutes.

　　浸泡之后往往会进行超声波清洗，这一步是提高清洗效果的关键。清洗槽内的超声波发生器产生高频振动，使碳氢溶剂中形成无数微小的气泡。这些气泡在振动过程中不断生成、长大，然后迅速破裂，产生强烈的冲击力。这种冲击力能够作用于工件表面及缝隙、盲孔等难以清洁的部位，将浸泡后松动的油污彻底剥离，确保工件每个角落都能得到清洁。超声波清洗的频率和功率会根据工件材质和结构进行调节，避免对精密零件造成损伤。

　　After soaking, ultrasonic cleaning is often performed, which is the key to improving the cleaning effect. The ultrasonic generator in the cleaning tank generates high-frequency vibration, causing countless tiny bubbles to form in the hydrocarbon solvent. These bubbles continuously generate and grow during the vibration process, and then quickly burst, generating strong impact force. This impact force can act on the surface of the workpiece, as well as on difficult to clean areas such as gaps and blind holes, thoroughly removing any loose oil stains after soaking, ensuring that every corner of the workpiece can be cleaned. The frequency and power of ultrasonic cleaning will be adjusted according to the material and structure of the workpiece to avoid damage to precision parts.

　　清洗完成后，工件会进入漂洗阶段。经过前面的清洗，工件表面可能还残留少量的溶剂和未完全脱离的细小污染物，漂洗就是为了去除这些残留物。漂洗槽中通常装有经过蒸馏提纯的纯净碳氢溶剂，工件在其中再次浸泡或受到喷淋，利用干净的溶剂将表面残留的杂质带走，进一步提高工件的洁净度。对于要求极高的精密工件，可能会进行多次漂洗，以确保达到规定的清洁标准。

　　After cleaning, the workpiece will enter the rinsing stage. After the previous cleaning, there may still be a small amount of solvent and incomplete detachment of small pollutants on the surface of the workpiece. Rinsing is to remove these residues. The rinsing tank usually contains pure hydrocarbon solvents that have been distilled and purified. The workpiece is soaked or sprayed in it again, and the residual impurities on the surface are taken away by the clean solvent, further improving the cleanliness of the workpiece. For precision workpieces with extremely high requirements, multiple rinses may be performed to ensure compliance with the specified cleaning standards.

　　漂洗之后是干燥处理。由于碳氢溶剂具有较强的挥发性，干燥过程相对简便。工件被转移到干燥槽后，设备会对其进行加热或通入热风，加速溶剂的挥发。同时，干燥槽通常与溶剂回收系统相连，挥发的溶剂蒸汽会被收集起来，送入蒸馏装置进行处理，避免直接排放造成浪费和污染。干燥时间根据工件的大小、材质以及环境温度而定，确保工件表面完全干燥，没有溶剂残留，不影响后续的加工或装配工序。

　　After rinsing, it is dried. Due to the strong volatility of hydrocarbon solvents, the drying process is relatively simple. After the workpiece is transferred to the drying tank, the equipment will heat it or introduce hot air to accelerate the evaporation of the solvent. At the same time, the drying tank is usually connected to the solvent recovery system, and the evaporated solvent vapor is collected and sent to the distillation unit for treatment, avoiding direct discharge that may cause waste and pollution. The drying time depends on the size, material, and ambient temperature of the workpiece, ensuring that the surface of the workpiece is completely dry, without solvent residue, and does not affect subsequent processing or assembly processes.

　　最后是溶剂回收与净化。在整个清洗过程中，使用过的碳氢溶剂会被收集到蒸馏槽中，通过加热使其蒸发成蒸汽。蒸汽进入冷却系统后液化，变成纯净的溶剂，重新输送到清洗槽或漂洗槽中循环使用。而蒸馏后留下的残渣，主要是从工件上剥离的油污和杂质，会被定期清理。这一环节不仅提高了溶剂的利用率，降低了运行成本，还减少了废弃物的排放，体现了碳氢清洗机的环保特性。

　　Finally, solvent recovery and purification. During the entire cleaning process, the used hydrocarbon solvents will be collected in the distillation tank and heated to evaporate into steam. After entering the cooling system, the steam liquefies and becomes a pure solvent, which is then transported back to the cleaning or rinsing tank for recycling. The residue left after distillation, mainly consisting of oil stains and impurities peeled off from the workpiece, will be cleaned regularly. This step not only improves the utilization rate of solvents and reduces operating costs, but also reduces waste emissions, reflecting the environmental characteristics of hydrocarbon cleaning machines.
