自动上料搅拌车漏油故障一般出现在哪些地方?

1、自动上料搅拌车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 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、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,用研磨法解决其锥面密封,使螺母压紧而解决密封。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,甚至发生事故。
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 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、是否是密封材料长期使用后磨损过限,老化变质、变形失效。

3. Whether the sealing material is worn out after long-term use, aging, deterioration, deformation and 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。自动上料搅拌车上良多动置部位(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 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 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.
