How to check if there is oil leakage in the vehicle

Time:2019-08-01 Views:1466
Common special vehicle oil leakage reasons:
1. The quality, material or process of the product (accessory) is not good, and the structural design has problems.
2, improper assembly, the surface of the parts is not clean, the gasket is damaged, displaced or not installed according to the operating procedures.
3. The unevenness of the tightening nut, the broken or falling of the sliding wire, etc., cause the work to fail.
4. The sealing material is excessively worn after long-term use, aging deterioration and deformation failure.
5. Too much oil is added, the oil level is too high or the fuel is added incorrectly.
6. The surface of the joints (side cover, thin-walled parts) is flexed and deformed, and the shell is damaged, so that the lubricating oil seeps out.
7. After the vent plug and the one-way valve are blocked, due to the difference of the air pressure inside and outside the oil tank, oil leakage may occur in the weak seal.
Prevent special oil spill measures:
Pay attention to the padding effect. The gasket between the components of the static part of the car acts as a leakproof seal. If the material, production quality and installation do not meet the technical specifications, it will not be able to seal and prevent leakage, and even accidents. For example, the oil pan or the valve cover is not easy to compact due to the large contact area, thereby causing oil leakage. All kinds of fastening nuts on the car must be tightened according to the specified torque. If the gasket is not tight, the gasket will leak; if it is too tight, the metal around the screw hole will be screwed or the thread will be screwed to cause oil leakage.
Timely replacement of many parts of the failed oil seal car (such as oil seals, O-rings) will be improperly installed, the journal and the oil seal edge are not concentric, yaw and oil. Some oil seals use too long to lose their elasticity due to rubber aging. It is found that the leakage should be updated in time.
Avoiding the check valve and vent valve blocking will cause the temperature inside the casing to rise. The oil and gas will fill the entire space and the discharge will not be exhausted, so that the pressure in the fuel tank will increase, the consumption of lubricating oil will increase and the replacement cycle will be shortened. After the engine ventilation system is blocked, the resistance of the piston is increased to increase the fuel consumption. The effect of the air pressure difference inside and outside the fuel tank often causes oil leakage at the weak seal. Therefore, the vehicle needs to be inspected regularly, dredged, and cleaned.
Properly solve the various types of tubing joint sealing car with the union nut often disassembled, easy to slip the wire and loosen, causing oil leakage. Replace the union nut, solve the cone seal with the grinding method, and tighten the nut to solve the seal.
Avoid excessive bearing oil in the hub bearing and the cavity, or its oil package is not properly equipped, the quality is poor and the aging is invalid. The temperature of the hub caused by the brake is too high, and the axle nut is loose, etc., which will cause the hub to simmer. Therefore, use a proper amount of lubrication to clear the vent.
