全自动搅拌车轴承损坏如何处理?

来源:http://www.zkzdsljbc.com/ 时间:2022-02-23

全自动混凝土搅拌车滑动轴承早期损坏比轴承烧毁要常见得多,因此预防滑动轴承早期损坏很重要。滑动轴承的正确维护是减少轴承早期损坏的有效途径,也是延长轴承寿命的可靠保证。因此,在发动机的日常维护和维修中,必须注意轴承的合金表面、背面、端头及边缘棱角处的外观形状,如有异常或出现过半磨损的征兆,就要认真查明原因,并采取相应的措施,改善轴承的工作条件,重视对滑动轴承早期损坏的预防.滑动轴承在气缸压力冲击载荷的反复作用下,表面层发生塑性变形和冷作硬化,局部丧失变形能力,逐步形成条纹并不断扩展,然后随着磨屑的脱落,在受载表面层形成凹穴。一般轴瓦发生穴蚀时,是先出现凹坑,然后这种凹坑逐步扩大并引起合金层界面的开裂,裂纹沿着界面的平行方向扩展,直到剥落为止。滑动轴承穴蚀的主要原因是,由于油槽和油孔等结构要素的横断面突然改变引起油流强烈紊乱,在油流紊乱的真空区形成气泡,随后由于压力升高,气泡溃灭而产生穴蚀。
The early damage of the sliding bearing of the full-automatic concrete mixer is much more common than the burning of the bearing, so it is very important to prevent the early damage of the sliding bearing. The correct maintenance of sliding bearing is not only an effective way to reduce the early damage of bearing, but also a reliable guarantee to prolong the service life of bearing. Therefore, in the daily maintenance and repair of the engine, attention must be paid to the appearance and shape of the alloy surface, back, end and edge corners of the bearing. If there are abnormalities or signs of excessive wear, it is necessary to carefully find out the causes, take corresponding measures, improve the working conditions of the bearing, and pay attention to the prevention of early damage of the sliding bearing Under the repeated action of cylinder pressure impact load, the surface layer of sliding bearing will undergo plastic deformation and cold work hardening, lose the deformation ability locally, gradually form stripes and expand continuously, and then form pits in the loaded surface layer with the falling off of wear debris. Generally, when the bearing bush is pitted, the pit first appears, and then the pit gradually expands and causes the cracking of the alloy layer interface. The crack extends along the parallel direction of the interface until it peels off. The main reason for the cavitation of sliding bearing is that the sudden change of the cross section of structural elements such as oil groove and oil hole causes the strong disorder of oil flow, forming bubbles in the vacuum area with disordered oil flow, and then cavitation occurs due to the collapse of bubbles due to the increase of pressure.中科聚峰
穴蚀一般发生在轴承的高载区,如曲轴主轴承的下轴瓦上。轴承走外圆轴承走外圆就是轴承在座孔内有相对转动。轴承走外圆后,不仅影响轴承的散热,容易使轴承内表面合金烧蚀,而且还会使轴承背面损伤,严重时烧毁轴承。其主要原因是,轴承过短、凸榫损伤、加工或者安装不符合规范等。搅拌车,混凝土搅拌车,水泥搅拌车,搅拌车价格,水泥罐车任何质量等级的润滑油在使用过程中油质都会发生变化。到一定里程之后,性能恶化,会给发动机带来种种问题。为了避免故障的发生,应结合使用条件定期换油,并使油量适中。机油从滤清器的细孔通过时把油中的固体颗粒和粘稠物积存在滤清器中。如滤清器堵塞,机油不能通过滤芯时,会胀破滤芯或打开安全阀,从旁通阀通过,仍把脏物带回润滑部位,促使发动机磨损,内部的污染加剧。混凝土搅拌车底盘。汽车底盘是混凝土搅拌车组成中成本最高、使用中维护费用最高的部分。混凝土搅拌车的汽车底盘,重点主要看该底盘的发动机功率和扭矩、油耗、轮胎、车架、驾驶舒适性及排放标准等方面,所以选择正规厂家生产的混凝土搅拌车以保证车辆在使用过程中,故障率低,维修成本低,损耗费用低。
Cavitation usually occurs in the high load area of the bearing, such as the lower bearing bush of the crankshaft main bearing. The outer circle of bearing means that the bearing has relative rotation in the seat hole. After the bearing goes to the outer circle, it will not only affect the heat dissipation of the bearing, which is easy to ablate the alloy on the inner surface of the bearing, but also damage the back of the bearing and burn the bearing in serious cases. The main reason is that the bearing is too short, the tenon is damaged, and the processing or installation does not meet the specifications. Mixer truck, concrete mixer truck, cement mixer truck, the price of mixer truck, and the quality of lubricating oil of any quality grade of cement tank truck will change during use. After a certain mileage, the performance deteriorates, which will bring various problems to the engine. In order to avoid the occurrence of faults, the oil should be changed regularly in combination with the service conditions, and the oil volume should be moderate. When the oil passes through the fine hole of the filter, the solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and the oil cannot pass through the filter element, the filter element will be broken or the safety valve will be opened to pass through the bypass valve, and the dirt will still be brought back to the lubrication part, which will promote the wear of the engine and aggravate the internal pollution. Concrete mixer chassis. The automobile chassis is the part with the highest cost and maintenance cost in the composition of concrete mixer. The automobile chassis of concrete mixer truck mainly focuses on the engine power and torque, fuel consumption, tires, frame, driving comfort and emission standards of the chassis. Therefore, the concrete mixer truck produced by regular manufacturers is selected to ensure that the vehicle has low failure rate, low maintenance cost and low loss cost in the process of use.
