全自動攪拌車軸承損壞如何處理?

全自動混凝土攪拌車滑動軸承早期損壞比軸承燒毀要常見得多,因此預防滑動軸承早期損壞很重要?;瑒虞S承的正確維護是減少軸承早期損壞的有效途徑,也是延長軸承壽命的可靠保證。因此,在發動機的日常維護和維修中,必須注意軸承的合金表面、背面、端頭及邊緣棱角處的外觀形狀,如有異?;虺霈F過半磨損的征兆,就要認真查明原因,并采取相應的措施,改善軸承的工作條件,重視對滑動軸承早期損壞的預防.滑動軸承在氣缸壓力沖擊載荷的反復作用下,表面層發生塑性變形和冷作硬化,局部喪失變形能力,逐步形成條紋并不斷擴展,然后隨著磨屑的脫落,在受載表面層形成凹穴。一般軸瓦發生穴蝕時,是先出現凹坑,然后這種凹坑逐步擴大并引起合金層界面的開裂,裂紋沿著界面的平行方向擴展,直到剝落為止?;瑒虞S承穴蝕的主要原因是,由于油槽和油孔等結構要素的橫斷面突然改變引起油流強烈紊亂,在油流紊亂的真空區形成氣泡,隨后由于壓力升高,氣泡潰滅而產生穴蝕。
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
穴蝕一般發生在軸承的高載區,如曲軸主軸承的下軸瓦上。軸承走外圓軸承走外圓就是軸承在座孔內有相對轉動。軸承走外圓后,不僅影響軸承的散熱,容易使軸承內表面合金燒蝕,而且還會使軸承背面損傷,嚴重時燒毀軸承。其主要原因是,軸承過短、凸榫損傷、加工或者安裝不符合規范等。攪拌車,混凝土攪拌車,水泥攪拌車,攪拌車價格,水泥罐車任何質量等級的潤滑油在使用過程中油質都會發生變化。到一定里程之后,性能惡化,會給發動機帶來種種問題。為了避免故障的發生,應結合使用條件定期換油,并使油量適中。機油從濾清器的細孔通過時把油中的固體顆粒和粘稠物積存在濾清器中。如濾清器堵塞,機油不能通過濾芯時,會脹破濾芯或打開安全閥,從旁通閥通過,仍把臟物帶回潤滑部位,促使發動機磨損,內部的污染加劇?;炷翑嚢柢嚨妆P。汽車底盤是混凝土攪拌車組成中成本最高、使用中維護費用最高的部分?;炷翑嚢柢嚨钠嚨妆P,重點主要看該底盤的發動機功率和扭矩、油耗、輪胎、車架、駕駛舒適性及排放標準等方面,所以選擇正規廠家生產的混凝土攪拌車以保證車輛在使用過程中,故障率低,維修成本低,損耗費用低。
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.
