Precautions for Oil Leakage in Special Purpose Vehicles

With the continuous use of special vehicles and the increase in vehicle age, it is inevitable that sprinklers will leak oil. The oil leakage will directly affect the technical performance of the vehicle, resulting in a large amount of wasted lubricants and fuel, consuming power, and affecting vehicle capacity. Being tidy will also cause environmental pollution. And with the continuous reduction of oil leakage and internal lubricants of the machine, it will lead to poor lubrication of the parts and insufficient cooling, leading to early damage of the parts and even leaving hidden accidents. Here we learn together how to prevent vehicle oil leakage?

Pay attention to the role of cushions. The gasket between the standing parts of the sprinkler (such as the joint end face, the end caps, the housing, the cover gasket, the plane cover plate, etc.) plays a role of leakproof sealing. If the material, production quality and installation do not meet the technical specifications, it will not achieve sealing leakage, even accidents. Such as the oil pan or valve cover, due to the large contact area and difficult to compact, resulting in oil spills.

All types of fastening nuts on special purpose vehicles must be tightened according to the specified 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 screw the screw to cause oil leakage. In addition, if the oil drain plug of the oil pan is not tightened or loosened, it will easily cause the loss of oil, and then the machine damage of “burning and holding the shaft” will occur.

Replace the failed oil seal in time. Many moving parts on the car (such as oil seals, O-rings) will be improperly installed, the journal and the oil seal blade are not the same, and the oil will be thrown off. Some oil seals used for too long will lose their elasticity due to aging of the rubber. Found leakage should be replaced in time oil seal.

Avoid check valve, vent valve blocked. As a result, the temperature in the enclosure rises, oil and gas fill the entire space, and emissions do not go out. As a result, the pressure in the enclosure increases and the lubricant consumption increases and the replacement cycle shortens. When the sprinkler engine's ventilation system is blocked, it increases the piston's resistance to movement and increases fuel consumption. Due to the pressure difference between the inside and outside of the enclosure, it often causes oil leakage in the weak sealing area. Therefore, vehicles need to be regularly inspected, dredged and cleaned.

Properly solve all types of oil pipe joint seals. The joint nut of the vehicle is often disassembled and assembled, and it is easy for the slip wire to break and loosen, which can cause oil leakage. Replace the union nut, use a grinding method to solve the cone seal, make the nut tight and solve the seal.

Avoid hub throwing oil. Wheel hub bearings and cavity too much lubricating oil, or its oil package is not properly equipped, poor quality and aging failure; brakes frequently caused by the hub temperature is too high; axle nut loose, etc. will cause the hub to throw oil. Therefore, use the "cavity lubrication method, that is, proper lubrication, to clear the ventilation hole.
