Engine maintenance It is believed that everyone understands that the effect of vehicle performance and driving quality after oil change is immediate, so many users also pay attention to regular maintenance. However, like the maintenance of the gearbox and the rear axle, some users are a little despised. Heavy-duty gearboxes, even if it is a long oil change, manufacturers generally recommend changing the oil cycle is only 100,000 kilometers. However, many users will think that the oil change cycle is conservative, and 200,000 kilometers can never be exchanged. Some old drivers will tell you through past experience that there is no problem if the gearbox does not change oil to 500,000 kilometers or even if the vehicle is scrapped. If a certain gear collapses, it will take over 2,000 to go overhauled. Some gearboxes have three to four hundred thousand kilometers of oil change, driving is not easy to feel, but the gearbox is really not a problem? In order to save maintenance costs, is it worthwhile to encourage maintenance? Earlier, the Dongfeng Tianlong ZF gearbox with users did not change oil for a long time, the 4th gear of the countershaft was damaged, and overhaul took more than 3,000. Cardmates commented that there are two reasons for tooth fractures. One is the lack of gear hardness and the second is improper operation. Gear oil is important but not the main cause. Although reasonable in view, it must be based on proper maintenance. The role of gear oil is lubrication and cooling. If the transmission does not change oil 500,000 kilometers, even if the gear has not been damaged, the internal parts, including shafts and gears, have in fact been affected in intensity and have declined more than normal maintenance. Faster. One of the gears in the overhaul was replaced due to damage. The other internal parts seem to be intact, and in fact only the potential risk of damage is not revealed. The damage to a single gear like this gearbox is not a big problem, and the maintenance price is not too high. To liberate the 12-speed transmission, for example, Guangzhou, a 4S shop service station reported the maintenance price, parts processing is about 4,000 or so, not in the 4S maintenance, then the price is much lower, the following 3,000 prices can get. Therefore, some people think that if one does not change oil for 500,000 kilometers, it will only be a bad tooth, and overhaul is lower than the maintenance price during this period. This is also the value. Is this really the case? Don't forget to mention above that even if only one tooth is broken at the moment, because the strength of other parts is also reduced due to lack of lubrication and cooling over a long period of time, the subsequent bad situation may be that other gears and even the shaft is damaged. . The car is bad on the road. Loss of time and efficiency is also a waste of time. It is not worth the effort. Knowing how to maintain it properly can greatly reduce this situation. Carbon Steel Fuel Tank Semi-trailer Fuel tank semi-trailer is mainly used for large-scale oil transportation, and the tonnage is generally about 40 ~ 60 cubic meters. There are usually two axle semi-trailer and three axle semi-trailer. The square tank body of the oil semi-trailer is made of Q235A steel plate. The tank body is built with multiple reinforced anti wave baffle plates, and the lower end of the baffle plate is provided with through holes to reduce the impact of oil in the tank and improve the strength of the tank body during vehicle driving. The combined tank mouth is located at the top of the tank body, there is a self-locking small cover on the large cover, and a breathing valve is installed on the upper side of the large cover to ensure the consistency of atmospheric pressure inside and outside the tank; With electrostatic grounding wire. Install the pump oil system, take the power from the transmission side through the power take-off, which can be self-priming and self draining; With two oil pumping pipes, equipped with quick fitting joints, with a suction lift of 6m. Two fire extinguishers and special tools. The oil semi-trailer is divided into two parts, the oil tank body and the framework or bracket supporting the tank body.
