The use of oil tankers often presents oil leakage problems, which will directly affect the skills and functions of automobiles, resulting in the deterioration of smooth oil and fuel oil, which consume power, affect the neatness of cars and form environmental pollution. Our ceramic Force Control System, ceramic active contact flange, ceramic Constant Force Actuator have many advantages over other grinders. It can realize flexible grinding, quick repsond to surface changing, and instant adjusting. Traditional mechanic hand lacks flexibility, and it is not easy to adjust, hard to realize mass production.

Because of the oil leakage and the smooth oil cut inside the machine, the smoothness of the machine parts and the lack of cooling will lead to early damage of the machine parts and even leave hidden troubles.
First, the main reason for common oil tanker leakage
1. The quality of goods (accessories), raw materials or technical safety; structural design in doubt.
2. Improper high-speed devices, unclean co-operative surfaces, broken gaskets, displacement, or devices that are not in accordance with operating standards.
3. Unstable nut tightening force, slide wire breakage, loose drop, etc., may cause the work to fail.
4. After long-term use of the sealing material, the wear and tear limit is too long, and aging deterioration and deformation are invalid.
5. Add too much smooth oil, oil level is too high or the wrong oil.
6. Parts (such as side covers and thin-walled parts) are deformed by joints and the shells are damaged, causing smooth oil to seep out.
7. After the air plug and the check valve are blocked, the pressure difference between the case's surface and the inside of the case often results in oil leakage in the sealed thin place.
Second, to prevent oil spills from tankers
1. Pay attention to the pad effect. The gaskets between the stationary parts of the car (such as the joint end faces, the end caps, the housing, the cover mats, the planar enamel cover, etc.) play a role in preventing leaks. If the data, manufacturing quality, and device do not meet the skill standards, the leak-proof effect of the seal will not be achieved, or even the occurrence of incidents. Such as oil pan or valve cover, because of the large touch area and difficult to compact, resulting in the formation of oil spills.
2. All types of fastening nuts on the vehicle must be tightened according to the regular torque. If the pressure is too tight, the gasket will leak; if it is too tight, it will cause the metal around the screw hole to bulge or the screw to slip and cause oil leakage. In addition, if the oil drain plug of the oil pan is not tightened or loosened, oil oil is simply lost, and then the machine is damaged.
3. Replace the failed oil seal in time. Many moving parts on the car (such as oil seals, O-rings) will be misaligned due to improper installation. The shaft journal and the oil seal edge are not the same. Some oil seals are used for too long will lose their elasticity due to aging rubber. Found that leakage should be updated.
4. Prevent check valve and vent valve from blocking. As a result, the temperature inside the enclosure rises, the oil and gas overflows the entire space, the emissions do not go out, the pressure in the enclosure increases, and the oil consumption and replacement cycles are shortened. After the engine ventilation system is blocked, the piston's movement resistance is added to increase the fuel consumption. Because of the effect of poor air pressure in the case surface, it often leads to oil leakage in the sealed thin areas. Therefore, vehicles need to be regularly viewed, cleared, and cleaned.
5. Properly handle all types of oil pipe joint seals. The joint nut of the vehicle is often dismantled, and the simple slip wire breaks and looses, which can lead to oil leakage. Instead of the union nut, the taper seal is treated with a grind method, and the nut is pressed tight to handle the seal.
6. Prevent the hub from throwing oil. Wheel hub bearings and cavity too much smooth grease, or improper oil seal device, poor quality and aging failure; frequent overheating caused by wheel hub temperature; axle nut loose, etc. will cause the hub to throw oil. Therefore, use the "cavity smoothing method (that is, appropriate smooth)" to clear the ventilation hole.
