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

　　在工業(yè)精密清洗領(lǐng)域，碳氫清洗機憑借環(huán)保、無腐蝕、清潔度高的優(yōu)勢，廣泛應用于汽車零部件、電子元件、模具等行業(yè)，尤其適配高壓去毛刺清洗后的精密工件二次清潔，彌補傳統(tǒng)清洗殘留隱患。但很多企業(yè)在使用中會遇到兩大棘手問題：蒸餾槽與再生槽無液、清洗后產(chǎn)品殘留清洗液，據(jù)行業(yè)數(shù)據(jù)統(tǒng)計，這類故障中90%源于濾芯堵塞，今天就跟大伙嘮透碳氫清洗機的常見故障、排查技巧及核心注意事項。

　　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.

　　先理清核心邏輯：碳氫清洗機的正常運行，依賴儲液槽（ET槽）、蒸餾槽、再生槽的液體循環(huán)，以及過濾系統(tǒng)的通暢性，其中濾芯承擔著過濾清洗液中雜質(zhì)、鐵屑、毛刺殘留的關(guān)鍵作用，一旦堵塞，會直接引發(fā)全流程液體循環(huán)故障，進而導致工件清洗殘留，影響產(chǎn)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.

　　最常見的兩大故障，根源往往指向同一個問題。第一個高頻故障是蒸餾槽、再生槽無液，很多操作員會誤以為是清洗液耗盡，盲目補充碳氫溶劑，反而增加成本。實則90%的情況的是濾芯堵塞，尤其是再生槽管路的過濾器和Y型過濾器，長期過濾雜質(zhì)后易造成堵塞，導致儲液槽內(nèi)的清洗液無法正常輸送至蒸餾槽、再生槽，形成“無液假象”。

　　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".

　　第二個關(guān)聯(lián)故障是清洗后產(chǎn)品殘留清洗液。當濾芯堵塞，清洗液循環(huán)流速會下降30%以上，無法形成穩(wěn)定的清洗液噴淋壓力（正常工況需維持0.3-0.5MPa），工件表面的碳氫清洗液難以徹底瀝干，同時堵塞的濾芯會導致清洗液純度下降，雜質(zhì)混入后更易附著在工件表面，最終造成殘留，嚴重時會導致產(chǎn)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.

　　掌握兩步排查法，快速解決80%的循環(huán)與殘留問題。第一步，優(yōu)先檢查儲液槽（ET槽）液位，確保液位處于標準刻度線（通常為槽體容積的60%-80%），若液位低于40%，需補充適配型號的碳氫清洗液，避免因液位不足導致循環(huán)中斷；第二步，重點檢查濾芯，拆解再生槽管路過濾器及Y型過濾器，查看濾芯污染情況--若濾芯表面附著大量雜質(zhì)、鐵屑，或通透度不足50%，即可判定為堵塞，需及時更換濾芯。

　　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.

　　這里有個關(guān)鍵提醒：濾芯的更換周期需嚴格把控，不可盲目延長。根據(jù)行業(yè)實操數(shù)據(jù)，常規(guī)工況下，碳氫清洗機濾芯每150-200小時需檢查一次，每300小時強制更換，若用于高壓去毛刺后的工件清洗（雜質(zhì)、毛刺更多），需縮短至每200小時更換一次，可降低95%以上的堵塞故障發(fā)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%.

　　除了濾芯堵塞，還有幾點細節(jié)易被忽略，也可能引發(fā)類似故障。比如管路接頭密封不嚴，會導致清洗液泄漏，間接造成蒸餾槽、再生槽無液，泄漏率若超過5%，需及時更換密封件；蒸餾槽加熱管結(jié)垢，會影響溶劑蒸餾回收效率，導致再生槽液體補充不及時，建議每6個月清理一次加熱管結(jié)垢，提升蒸餾效率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%.

　　碳氫清洗機的清潔效果，與過濾系統(tǒng)和循環(huán)系統(tǒng)的通暢性直接相關(guān)。以高壓去毛刺后的汽車齒輪清洗為例，合格的碳氫清洗機可將工件表面清洗液殘留量控制在5mg/㎡以內(nèi)，遠超行業(yè)標準，而一旦濾芯堵塞，殘留量會飆升至20mg/㎡以上，無法滿足精密零件裝配要求。定期維護濾芯，不僅能減少故障，還能提升清洗液循環(huán)利用率，降低30%的溶劑消耗成本。

　　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%.

　　總結(jié)來說，碳氫清洗機的常見故障無需過度頭疼，抓住“濾芯排查”這個核心，就能解決90%的循環(huán)無液、產(chǎn)品殘留問題。搭配定期檢查儲液槽液位、清理管路雜質(zhì)、更換密封件等維護動作，既能保障設(shè)備穩(wěn)定運行，又能提升產(chǎn)品清潔合格率，延長設(shè)備使用壽命。對依賴精密清洗的企業(yè)而言，掌握這些實操技巧，能有效減少停工損失，實現(xiàn)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.
