自動上料攪拌車漏油故障一般出現(xiàn)在哪些地方？
1、自動上料攪拌車上各類螺母都是否擰緊，車用聯(lián)管螺母常常拆裝，輕易滑絲斷扣而松脫，會引起滲油。
1. Whether all kinds of nuts on the automatic feeding mixer are tightened, and the vehicle union nuts are often disassembled, which is easy to slip, break and loosen, which will cause oil leakage.
2、裝配是否不當，表面是否不清潔，襯墊破損、位移或未按操縱規(guī)程規(guī)范進行安裝。更換聯(lián)管螺母，用研磨法其錐面密封，使螺母壓緊而密封。如油底殼或氣門罩蓋，因為接觸面積大而不易壓實，由此造成漏油，若在材料、制作質(zhì)量及安裝上不符合技術(shù)規(guī)范，就起不到密封防漏作用，甚發(fā)生事故。
2. Whether the assembly is improper, whether the surface is not clean, whether the gasket is damaged, displaced or not installed according to the operating procedures and specifications. Replace the union nut and solve the conical seal by grinding to compress the nut. For example, the oil pan or valve cover is not easy to compact due to large contact area, resulting in oil leakage. If the material, manufacturing quality and installation do not meet the technical specifications, it will not play the role of sealing and leakage prevention, and even accidents will occur.
3、是否是密封材料長期使用后磨損過限，老化變質(zhì)、變形失效。
3. Whether the sealing material is worn out after long-term use, aging, deterioration, deformation and failure.
4、是否是輪轂甩油。由此引起箱殼內(nèi)溫度升高，油氣布滿整個空間、排放不出去，使箱殼內(nèi)壓力升高潤滑油消耗增加和更換周期縮短。自動上料攪拌車上良多動置部位（如油封、Ｏ型圈）會因安裝不妥，軸頸與油封刃口不同心，偏擺而甩油。輪轂軸承及腔內(nèi)潤滑油脂過多，或其油封裝配不妥，質(zhì)量不良及老化失效；制動頻繁引起的輪轂溫渡過高；車軸螺母松動等都會引起輪轂甩油，發(fā)現(xiàn)滲漏應(yīng)及時更新。
4. Whether it is hub oil rejection. As a result, the temperature in the tank shell increases, the oil and gas fills the whole space and cannot be discharged, so that the pressure in the tank shell increases, the lubricating oil consumption increases and the replacement cycle shortens. Many moving parts (such as oil seal and O-ring) on the automatic feeding mixer will shed oil due to improper installation, misalignment between the journal and the oil seal edge and deflection. Excessive lubricating grease in hub bearing and cavity, or improper oil packaging, poor quality and aging failure; The hub temperature transition caused by frequent braking is too high; Looseness of axle nut will cause oil rejection of wheel hub, and it shall be updated in time in case of leakage.
5、是否是緊固螺母擰力不均、滑絲斷扣或松曠脫落等導致工作失效，過松壓不緊襯墊會滲漏；過緊又會使螺孔附近金屬突出或?qū)⒔z扣擰滑而引起漏油。
5. Whether the uneven tightening force of the fastening nut, the broken buckle of the sliding wire or the looseness and falling off cause the work failure, and the gasket will leak if it is too loose and not tightly pressed; Too tight will make the metal near the screw hole protrude or screw thread slip, resulting in oil leakage.
