In the use of vehicles, often appear leakage fault, it will directly affect the performance of automotive technology, resulting in lubricating oil, fuel waste, power consumption, influence the vehicle clean, causing environmental pollution. Due to the oil spill, the interior of the machine lubricating oil is reduced, resulting in poor lubrication, cooling machine is insufficient, cause parts of early damage, even leave hidden dangers of accidents.
First, the main causes of common vehicle oil spills
1 product quality, material or poor workmanship; structural design problems.
2 improper assembly of high speed, with the surface is not clean, gasket damage, displacement or not according to the operating rules of the installation.
The 3 fastening nut force uneven, slippery silk off button or Songkuang off work as a result of failure.
4 after long-term use of the sealing material wear limit, aging metamorphism, deformation failure.
5 too much oil, oil surface is too high or wrong oil.
6 parts of the joint surface deflection deformation, shell damage, so that the oil seepage.
7 North Ben V3 accessories vent plug, one-way valve plug, due to the pressure difference between the inside and outside the box shell, often caused by the leakage of oil seal.
Two, to prevent vehicle leakage measures
1 pay attention to the role of padding. Auto static site parts between the liner plays a role in leakproof. If the material, production and installation of quality does not meet the technical specifications, would not achieve the role of leak proof seal, and even accidents. If the oil pan or the valve cover, the contact area is large and easy to compaction, the resulting oil spill.
2 all kinds of fastening nuts are required to tighten according to the specified torque. Pressure is not too loose gasket leak tight; tight around the metal bumps and lead screw or screw thread work caused by oil spills. In addition, the oil pan drain plug loose if not tightened or back off, easy to cause the loss of oil, and then the engine damage accident burnt axle “of.
3 replace the oil seal in time. Many moving parts on the car because of improper installation, the shaft neck and the oil seal edge is not concentric, swing and throw oil. Some oil seals have been used for a long time due to the loss of elasticity of rubber aging. Found leakage should be updated.
4 avoid one-way valve, vent valve block. As a result, the temperature in the case is increased, the oil and gas are filled with the whole space, and the discharge is not allowed. The pressure in the case is increased, the consumption of the lubricating oil is increased, and the replacement period is shortened. 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 between the inside and outside of the box and the role of the body, often caused by the leakage of oil seal. Therefore, the need for regular inspection of vehicles, dredging, cleaning.
5. Properly solve the North rush V3 fittings various types of tubing joint seal. The joint nut of the automobile is often disassembled and assembled, which is easy to slide and break, and can cause oil leakage. Replacing the union nut, sealed with grinding method to solve the cone, the nut tightly and solve the seal.
6 to avoid the North rush V3 parts hub oil. Hub bearing and grease in the cavity too much, or its oil packaging is not appropriate, poor quality and aging failure; frequent braking caused by the high temperature of the hub; axle nut loosening and so will cause the hub oil. Therefore, the use of “cavity lubrication method” to clear the pores.
