在混凝土搅拌机的使用过程中，偶尔会出现漏油的情况，如果不能及时处理，可能会引起机件早期损坏，甚留下事故隐患，因此需要我们对造成混凝土搅拌机漏油的原因进行分析排查，以此来避免事故的发生。接下来的文章内容，我们就带大家来分析一下混凝土搅拌机漏油的原因。

In the process of using the concrete mixer, oil leakage occasionally occurs. If it can not be handled in time, it may cause early damage to the parts, and even leave hidden dangers. Therefore, we need to analyze and investigate the causes of oil leakage of the concrete mixer, so as to avoid accidents. In the following article, we will take you to analyze the causes of oil leakage of concrete mixer.

混凝土搅拌机漏油故障原因排查：

Troubleshooting for oil leakage of concrete mixer:

1、混凝土搅拌机上各类螺母都是否拧紧，车用联管螺母常常拆装，轻易滑丝断扣而松脱，会引起渗油。

1. Whether all kinds of nuts on the concrete mixer are tightened or not, and the vehicle union nut is often disassembled and disassembled, which is easy to slide, break and loose, and cause oil leakage.

2、装配是否不当，表面是否不清洁，衬垫破损、位移或未按操纵规程规范进行安装。更换联管螺母，用研磨法其锥面密封，使螺母压紧而密封。如油底壳或气门罩盖，因为接触面积大而不易压实，由此造成漏油，若在材料、制作质量及安装上不符合技术规范，就起不到密封防漏作用，甚发生事故。

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. Replace the union nut, and use the grinding method to solve its cone sealing, so that the nut is compressed to solve the sealing problem. For example, the oil pan or valve cover is not easy to be compacted because of its 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, or even accidents.

3、是否是密封材料长期使用后磨损过限，老化变质、变形失效。

3. Whether it is the sealing material after long-term use wear limit, aging deterioration, deformation failure.

       

4、是否是轮毂甩油。由此引起箱壳内温度升高，油气布满整个空间、排放不出去，使箱壳内压力升高润滑油消耗增加和更换周期缩短。混凝土搅拌机上良多动置部位（如油封、Ｏ型圈）会因安装不妥，轴颈与油封刃口不同心，偏摆而甩油。轮毂轴承及腔内润滑油脂过多，或其油封装配不妥，质量不良及老化失效；制动频繁引起的轮毂温渡过高；车轴螺母松动等都会引起轮毂甩油，发现渗漏应及时更新。

4. Whether it's hub oil rejection. As a result, the temperature in the tank increases, the oil and gas fill the whole space and cannot be discharged, the pressure in the tank increases, the consumption of lubricating oil increases and the replacement period shortens. Many moving parts of concrete mixer (such as oil seal and O-ring) will throw oil due to improper installation, misalignment between shaft neck and oil seal edge and deflection. There is too much grease in the hub bearing and cavity, or the oil package is not matched properly, with poor quality and aging failure; The wheel hub temperature transition caused by frequent braking is too high; If the axle nut is loose, it will cause the hub to throw oil. If leakage is found, it should be updated in time.

5、是否是紧固螺母拧力不均、滑丝断扣或松旷脱落等导致工作失效，过松压不紧衬垫会渗漏；过紧又会使螺孔附近金属突出或将丝扣拧滑而引起漏油。

5. Whether the work failure is caused by uneven tightening force of fastening nut, broken thread or looseness, and the gasket will leak if it is too loose or not tight; If it is too tight, the metal near the screw hole will protrude or the screw thread will slip, causing oil leakage.

以上便是混凝土搅拌机漏油故障原因排查，希望对您有所帮助。
