The least problem with tubing joints is the sealing problem. Because it is used in automobiles, and automobile oil leakage can be large or small, and it can even endanger the safety of drivers. Tell everyone some ways to prevent automobile oil leakage. Pay attention to the role of cushioning. The gasket between the parts of the stationary part of the car acts as a leak-proof seal. If the material, production quality and installation do not meet the technical specifications, the sealing and leakage prevention function will not be achieved, and accidents may even occur. For example, the oil pan or valve cover is not easy to compact due to the large contact area, which causes oil leakage.
In addition to the oil pipe joints, all kinds of fastening nuts on the car must be tightened according to the specified torque. If the packing is too loose or not tight, the gasket will leak; if it is too tight, the metal around the screw hole will bulge or the thread will cause oil leakage. In addition, if the oil sump oil drain plug is not tightened or loosened, it is easy to cause oil loss. Many moving parts on the car will be incorrectly installed, and the journal and the oil seal edge will not be concentric, and the oil will be thrown off. Some oil seals will lose their elasticity due to rubber aging when used for too long. Any leakage should be updated in time.
Avoid blocking of check valves and vent valves. As a result, the temperature in the tank is increased, and the oil and gas fill the entire space and cannot be discharged, which increases the pressure in the tank and 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 fuel consumption is increased. Due to the difference in air pressure between the inside and outside of the tank shell, it often causes oil leakage at the oil pipe joints or weak seals. Therefore, regular inspections, dredging, and cleaning of vehicles are required.
