奔馳汽車預防車輛漏油的措施有哪些?

來源:http://www.pxhecheng.com發布時間:2021-09-07 15:10:29

1.重視襯墊作用。汽車靜置部位(如各接合端面、各端蓋、殼體、罩墊、平面琺瑯蓋板等)零部件之間的襯墊起著防漏密封作用。若在材料、制作質量及安裝上不符合技術規范,就起不到密封防漏作用,甚至發生事故。如油底殼或氣門罩蓋,由于接觸面積大而不易壓實,由此造成漏油。拆裝時注意妥善放置,仔細檢查,并按規范裝配。
1. Pay attention to the function of cushion. The gasket between the parts of the stationary parts of the automobile (such as each joint end face, each end cover, shell, cover pad, flat enamel cover plate, etc.) plays a leak proof sealing role. 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. Such as oil pan or valve cover, it is difficult to compact due to large contact area, resulting in oil leakage. During disassembly and assembly, pay attention to proper placement, careful inspection and assembly according to specifications.
2.車上各類緊固螺母都需按規定的扭矩擰緊。過松壓不緊襯墊會滲漏;過緊又會使螺孔周圍金屬凸起或將絲扣擰滑而引起漏油。另外,油底殼放油螺塞若未擰緊或回松脫落,容易造成機油流失,繼而發生“燒瓦抱軸”的機損事故。
2. All kinds of fastening nuts on the vehicle shall be tightened according to the specified torque. The gasket will leak if it is too loose and not tightly pressed; Too tight will make the metal bulge around the screw hole or screw thread slip, resulting in oil leakage. In addition, if the oil drain plug of the oil pan is not tightened or loosened, it is easy to cause oil loss, and then the machine damage accident of "Bush burning and shaft holding" occurs.
3.及時更換失效油封。車上很多動置部位(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。有些油封使用過久會因橡膠老化而失運河彈性。發現滲漏應及時更新。
3. Replace the failed oil seal in time. Many moving parts on the vehicle (such as oil seal and O-ring) will shed oil due to improper installation, misalignment between the journal and the oil seal edge and deflection. Some oil seals will lose elasticity due to rubber aging if they are used for too long. If leakage is found, it shall be updated in time.

4.汽車零件使用過久會產生磨損過限(如活塞與汽缸等),導致燃燒室內高壓氣體竄入曲軸箱,并迫使機油外漏。因此,當加機油口蓋處廢氣外竄嚴重時,應及早檢修或更換磨損件。
4. Excessive wear of automobile parts (such as piston and cylinder) will lead to high-pressure gas in the combustion chamber channeling into the crankcase and forcing oil leakage. Therefore, when the exhaust gas at the oil filler cap is seriously channeled, the worn parts shall be repaired or replaced as soon as possible.
5.避免單向閥、通氣閥堵死。由此引起箱殼內溫度升高,油氣充滿整個空間、排放不出運河,使箱殼內壓力升高潤滑油消耗增加和更換周期縮短。發動機通氣系統堵塞后,增加了活塞的運動阻力,使油耗增加。由于箱殼內外氣壓差的作用,往往會引起密封薄弱處漏油。因此需對車輛進行定期檢查、疏通、清洗。
5. Avoid blocking the check valve and vent valve. As a result, the temperature in the tank shell increases, the oil and gas fills the whole space and cannot be discharged out of the canal, which increases the pressure in the tank shell, increases the consumption of lubricating oil and shortens the replacement cycle. After the engine ventilation system is blocked, the movement resistance of the piston is increased and the fuel consumption is increased. Due to the pressure difference inside and outside the tank shell, oil leakage at the weak seal is often caused. Therefore, the vehicle shall be inspected, dredged and cleaned regularly.
6.妥善解決各類油管接頭密封。車用聯管螺母經常拆裝,容易滑絲斷扣而松脫;兩接頭喇叭口精度差,兩錐面中心線不重合而接觸不良;錐度不同而不相吻合,由此均會引起滲油。更換聯管螺母,用研磨法解決其錐面密封,使螺母壓緊而解決密封。
6. Properly solve the sealing of various oil pipe joints. The union nut for vehicle is often disassembled and disassembled, which is easy to slip and break off; The accuracy of the bell mouth of the two joints is poor, and the center lines of the two conical surfaces do not coincide, resulting in poor contact; The taper is different but not consistent, which will cause oil leakage. Replace the union nut and solve the conical seal by grinding to compress the nut.
7.避免輪轂甩油。輪轂軸承及腔內潤滑油脂過多,或其油封裝配不妥,質量不良及老化失效;制動頻繁引起的輪轂溫度過高;車軸螺母松動等都會引起輪轂甩油。因此有用“空腔潤滑法(即適量潤滑)”,疏通通氣孔,嚴格選擇配件,并按工藝規范進行裝配和高速。
7. Avoid hub oil throwing. Excessive lubricating grease in hub bearing and cavity, or improper oil packaging, poor quality and aging failure; Excessive hub temperature caused by frequent braking; Loose axle nuts will cause oil rejection of the wheel hub. Therefore, the "cavity lubrication method (i.e. appropriate lubrication)" is used to dredge the vent hole, strictly select the accessories, and carry out assembly and high-speed according to the process specifications.
