碳氫清洗機作為工業清洗領域的高效設備，其清洗流程經過精心設計，能夠確保工件得到徹底清潔，同時實現碳氫溶劑的循環利用。了解這一流程，有助于更好地理解其工作原理和高效性的來源。

　　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預處理。在將工件放入清洗機之前，需要對其進行簡單處理。操作人員會先清除工件表面附著的大塊雜質，如金屬碎屑、灰塵結塊等，避免這些雜質進入清洗系統后污染溶劑或堵塞設備管路。對于帶有復雜結構的工件，比如帶有深孔、縫隙的零件，會檢查是否有纏繞的絲線、殘留的大塊油污等，必要時進行手工初步清理，為后續的深度清洗做好準備。預處理雖簡單，卻能有效提高整體清洗效率，減少設備運行中的故障風險。

　　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.

　　接下來進入核心的清洗階段，這一階段通常包含多個步驟，且會根據工件的污染程度和清潔要求進行調整。首先是浸泡清洗，將預處理后的工件放入裝有碳氫溶劑的清洗槽中，讓溶劑充分包裹工件。碳氫溶劑會逐漸滲透到油污內部，對其進行溶解，對于一些附著不牢固的油污，在浸泡過程中就會脫離工件表面。浸泡時間根據工件油污的厚度和性質而定，一般從幾分鐘到幾十分鐘不等。

　　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.

　　浸泡之后往往會進行超聲波清洗，這一步是提高清洗效果的關鍵。清洗槽內的超聲波發生器產生高頻振動，使碳氫溶劑中形成無數微小的氣泡。這些氣泡在振動過程中不斷生成、長大，然后迅速破裂，產生強烈的沖擊力。這種沖擊力能夠作用于工件表面及縫隙、盲孔等難以清潔的部位，將浸泡后松動的油污徹底剝離，確保工件每個角落都能得到清潔。超聲波清洗的頻率和功率會根據工件材質和結構進行調節，避免對精密零件造成損傷。

　　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，工件會進入漂洗階段。經過前面的清洗，工件表面可能還殘留少量的溶劑和未完全脫離的細小污染物，漂洗就是為了去除這些殘留物。漂洗槽中通常裝有經過蒸餾提純的純凈碳氫溶劑，工件在其中再次浸泡或受到噴淋，利用干凈的溶劑將表面殘留的雜質帶走，進一步提高工件的潔凈度。對于要求極高的精密工件，可能會進行多次漂洗，以確保達到規定的清潔標準。

　　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.

　　漂洗之后是干燥處理。由于碳氫溶劑具有較強的揮發性，干燥過程相對簡便。工件被轉移到干燥槽后，設備會對其進行加熱或通入熱風，加速溶劑的揮發。同時，干燥槽通常與溶劑回收系統相連，揮發的溶劑蒸汽會被收集起來，送入蒸餾裝置進行處理，避免直接排放造成浪費和污染。干燥時間根據工件的大小、材質以及環境溫度而定，確保工件表面完全干燥，沒有溶劑殘留，不影響后續的加工或裝配工序。

　　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.

　　最后是溶劑回收與凈化。在整個清洗過程中，使用過的碳氫溶劑會被收集到蒸餾槽中，通過加熱使其蒸發成蒸汽。蒸汽進入冷卻系統后液化，變成純凈的溶劑，重新輸送到清洗槽或漂洗槽中循環使用。而蒸餾后留下的殘渣，主要是從工件上剝離的油污和雜質，會被定期清理。這一環節不僅提高了溶劑的利用率，降低了運行成本，還減少了廢棄物的排放，體現了碳氫清洗機的環保特性。

　　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.
