滤芯堵塞=故障高发！碳氢清洗机90%常见问题速解指南

　　Filter blockage=high incidence of malfunctions! Quick guide to solving 90% common problems of hydrocarbon cleaning machine

　　在工业精密清洗领域，碳氢清洗机凭借环保、无腐蚀、清洁度高的优势，广泛应用于汽车零部件、电子元件、模具等行业，尤其适配高压去毛刺清洗后的精密工件二次清洁，弥补传统清洗残留隐患。但很多企业在使用中会遇到两大棘手问题：蒸馏槽与再生槽无液、清洗后产品残留清洗液，据行业数据统计，这类故障中90%源于滤芯堵塞，今天就跟大伙唠透碳氢清洗机的常见故障、排查技巧及核心注意事项。

　　In the field of industrial precision cleaning, hydrocarbon cleaning machines are widely used in industries such as automotive parts, electronic components, molds, etc. due to their advantages of environmental protection, non corrosion, and high cleanliness. They are particularly suitable for secondary cleaning of precision workpieces after high-pressure deburring cleaning, making up for the hidden residual problems of traditional cleaning. But many companies encounter two major thorny problems in use: no liquid in the distillation tank and regeneration tank, and residual cleaning solution in the cleaned products. According to industry data statistics, 90% of these failures are caused by filter blockage. Today, we will talk about common faults, troubleshooting techniques, and core precautions of hydrocarbon cleaning machines.

　　先理清核心逻辑：碳氢清洗机的正常运行，依赖储液槽（ET槽）、蒸馏槽、再生槽的液体循环，以及过滤系统的通畅性，其中滤芯承担着过滤清洗液中杂质、铁屑、毛刺残留的关键作用，一旦堵塞，会直接引发全流程液体循环故障，进而导致工件清洗残留，影响产品合格率。

　　First, clarify the core logic: the normal operation of the hydrocarbon cleaning machine relies on the liquid circulation of the storage tank (ET tank), distillation tank, and regeneration tank, as well as the smoothness of the filtration system. The filter element plays a key role in filtering impurities, iron filings, and burrs in the cleaning solution. Once blocked, it will directly cause a complete liquid circulation failure, leading to residual cleaning of the workpiece and affecting the product qualification rate.

　　最常见的两大故障，根源往往指向同一个问题。第一个高频故障是蒸馏槽、再生槽无液，很多操作员会误以为是清洗液耗尽，盲目补充碳氢溶剂，反而增加成本。实则90%的情况的是滤芯堵塞，尤其是再生槽管路的过滤器和Y型过滤器，长期过滤杂质后易造成堵塞，导致储液槽内的清洗液无法正常输送至蒸馏槽、再生槽，形成“无液假象”。

　　The two most common faults often stem from the same problem. The first high-frequency fault is that there is no liquid in the distillation tank and regeneration tank. Many operators may mistakenly think that the cleaning solution is exhausted and blindly supplement with hydrocarbon solvents, which actually increases costs. In fact, 90% of cases are caused by clogged filter elements, especially the filters and Y-shaped filters in the regeneration tank pipeline. After filtering impurities for a long time, it is easy to cause blockages, resulting in the inability of the cleaning solution in the storage tank to be transported to the distillation tank and regeneration tank normally, forming a "no liquid illusion".

　　第二个关联故障是清洗后产品残留清洗液。当滤芯堵塞，清洗液循环流速会下降30%以上，无法形成稳定的清洗液喷淋压力（正常工况需维持0.3-0.5MPa），工件表面的碳氢清洗液难以彻底沥干，同时堵塞的滤芯会导致清洗液纯度下降，杂质混入后更易附着在工件表面，最终造成残留，严重时会导致产品合格率下降至70%以下，增加返工成本。

　　The second related fault is residual cleaning solution in the product after cleaning. When the filter element is clogged, the circulation flow rate of the cleaning solution will decrease by more than 30%, and a stable cleaning solution spray pressure cannot be formed (normal working conditions need to maintain 0.3-0.5MPa). The hydrocarbon cleaning solution on the surface of the workpiece is difficult to completely drain. At the same time, the clogged filter element will cause a decrease in the purity of the cleaning solution, and impurities are more likely to adhere to the surface of the workpiece after mixing, ultimately resulting in residue. In severe cases, it can cause the product qualification rate to drop below 70%, increasing rework costs.

　　掌握两步排查法，快速解决80%的循环与残留问题。第一步，优先检查储液槽（ET槽）液位，确保液位处于标准刻度线（通常为槽体容积的60%-80%），若液位低于40%，需补充适配型号的碳氢清洗液，避免因液位不足导致循环中断；第二步，重点检查滤芯，拆解再生槽管路过滤器及Y型过滤器，查看滤芯污染情况--若滤芯表面附着大量杂质、铁屑，或通透度不足50%，即可判定为堵塞，需及时更换滤芯。

　　Master the two-step troubleshooting method to quickly solve 80% of circulation and residual problems. The first step is to check the liquid level of the storage tank (ET tank) first, ensuring that the liquid level is at the standard scale line (usually 60% -80% of the tank volume). If the liquid level is below 40%, it is necessary to supplement the appropriate type of hydrocarbon cleaning solution to avoid circulation interruption due to insufficient liquid level; Step 2, focus on inspecting the filter element, dismantling the regeneration tank pipeline filter and Y-shaped filter, and checking the contamination of the filter element - if there are a large number of impurities, iron filings attached to the surface of the filter element, or if the permeability is less than 50%, it can be judged as blocked and the filter element needs to be replaced in a timely manner.

　　这里有个关键提醒：滤芯的更换周期需严格把控，不可盲目延长。根据行业实操数据，常规工况下，碳氢清洗机滤芯每150-200小时需检查一次，每300小时强制更换，若用于高压去毛刺后的工件清洗（杂质、毛刺更多），需缩短至每200小时更换一次，可降低95%以上的堵塞故障发生率。

　　Here is a key reminder: the replacement cycle of the filter element needs to be strictly controlled and cannot be blindly extended. According to industry practical data, under normal operating conditions, the filter element of the hydrocarbon cleaning machine needs to be checked every 150-200 hours and replaced forcibly every 300 hours. If used for cleaning workpieces after high-pressure deburring (with more impurities and burrs), it needs to be shortened to every 200 hours, which can reduce the occurrence rate of blockage failures by more than 95%.

　　除了滤芯堵塞，还有几点细节易被忽略，也可能引发类似故障。比如管路接头密封不严，会导致清洗液泄漏，间接造成蒸馏槽、再生槽无液，泄漏率若超过5%，需及时更换密封件；蒸馏槽加热管结垢，会影响溶剂蒸馏回收效率，导致再生槽液体补充不及时，建议每6个月清理一次加热管结垢，提升蒸馏效率25%以上。

　　In addition to filter clogging, there are several details that are easily overlooked and may also cause similar malfunctions. For example, if the sealing of pipeline joints is not tight, it can lead to leakage of cleaning solution, indirectly causing no liquid in the distillation tank and regeneration tank. If the leakage rate exceeds 5%, the sealing components need to be replaced in a timely manner; The scaling of the heating tube in the distillation tank can affect the efficiency of solvent distillation recovery, resulting in delayed replenishment of liquid in the regeneration tank. It is recommended to clean the scaling of the heating tube every 6 months to improve distillation efficiency by more than 25%.

　　碳氢清洗机的清洁效果，与过滤系统和循环系统的通畅性直接相关。以高压去毛刺后的汽车齿轮清洗为例，合格的碳氢清洗机可将工件表面清洗液残留量控制在5mg/㎡以内，远超行业标准，而一旦滤芯堵塞，残留量会飙升至20mg/㎡以上，无法满足精密零件装配要求。定期维护滤芯，不仅能减少故障，还能提升清洗液循环利用率，降低30%的溶剂消耗成本。

　　The cleaning effect of the hydrocarbon cleaning machine is directly related to the smoothness of the filtration system and circulation system. Taking the cleaning of automotive gears after high-pressure deburring as an example, a qualified hydrocarbon cleaning machine can control the residual amount of cleaning solution on the surface of the workpiece within 5mg/㎡, far exceeding industry standards. However, once the filter element is clogged, the residual amount will soar to over 20mg/㎡, which cannot meet the requirements of precision parts assembly. Regular maintenance of the filter element can not only reduce malfunctions, but also improve the recycling rate of cleaning solution and reduce solvent consumption costs by 30%.

　　总结来说，碳氢清洗机的常见故障无需过度头疼，抓住“滤芯排查”这个核心，就能解决90%的循环无液、产品残留问题。搭配定期检查储液槽液位、清理管路杂质、更换密封件等维护动作，既能保障设备稳定运行，又能提升产品清洁合格率，延长设备使用寿命。对依赖精密清洗的企业而言，掌握这些实操技巧，能有效减少停工损失，实现降本增效。

　　In summary, the common faults of hydrocarbon cleaning machines do not require excessive headaches. By focusing on the core of "filter element troubleshooting", 90% of the problems of no liquid circulation and product residue can be solved. By regularly checking the liquid level in the storage tank, cleaning impurities in the pipeline, and replacing seals, maintenance actions can be taken to ensure stable operation of the equipment, improve product cleanliness and qualification rate, and extend the service life of the equipment. For enterprises that rely on precision cleaning, mastering these practical skills can effectively reduce downtime losses and achieve cost reduction and efficiency improvement.
