Long truck drivers may often encounter leakage problems, whether it is oil or diesel oil leakage will not only cause great waste to produce vehicles running more serious in static or friction fire, life and property safety of buried vehicles and driving under the great hidden dangers.
In general, the main reasons for the oil spill caused by the following 3 aspects:
The liner is not qualified.
The truck static parts (such as the joint end faces, each end cover, shell gasket, etc.) gasket between components play a role in leakproof. If the device does not fit the manufacturing quality and technical specifications, would not achieve the role of leak proof seal, and accident. If the oil pan or the valve cover, the contact area is large and easy to compaction, resulting in oil spill.
The various types of fastening nut loose
Pressure is not too loose gasket leak tight; tight and lead screw around the metal bulge or threaded screw slide caused by oil spill. In addition, Baotou beiben heavy truck parts sump oil drain plug loose if not tightened or back scattered, easy to form oil loss, and engine damage burning tile axle.
The oil seal aging failure
The car a lot of moving parts (such as oil seal, Baotou beiben heavy truck accessories O ring) because the device is wrong, shaft and seal edge misalignment, deflection and the oil. Some oil seals used for a long time will be lost because of rubber aging and found that leakage should be updated in a timely manner.
How to prevent leakage of trucks, to eliminate safety hazards:
First of all, to properly handle Baotou beiben heavy truck accessories of all kinds of oil pipe joint seal. Car coupling nut often disassembly, easy to slide off button and loose, will cause oil leakage. Change the union nut, sealed by grinding method to dispose of its cone, the nut pressing and sealing treatment.
Secondly, to prevent the wheel hub oil. Hub bearing and cavity smooth grease too much, or its oil packaging and improper, poor quality and aging failure; brake frequently caused by the wheel hub temperature transition is too high; axle nut loose and so will cause the wheel oil. So to use “cavity smooth method” (that is, the right amount of smooth) dredging vent.
And prevent the one-way valve, vent valve block. Which cause the temperature rise inside the box, oil and gas filled the entire space, the discharge does not come in, so that the pressure inside the tank to increase the smooth fuel consumption increases and change the cycle to shorten. After the infarction of the engine ventilation system, the movement resistance of the piston is increased, and the fuel consumption is increased. Because of the pressure difference between the inside and outside of the box, the seal is often caused by the thin oil leakage, and therefore need to be checked regularly, clear and clean the vehicle.
