How is it that the engineering dump semi-trailer is difficult to start?

When the vehicle is started in the morning, it may encounter the situation that the ignition is started several times before it starts. The semi-trailer also has the symptoms of high fuel consumption and power reduction, and even the car cannot be started after starting for a few days or the key cannot be returned to ON after starting. Location and other issues. In response to these problems, Shandong Hongsheng vehicle maintenance personnel gave a diagnosis.

Ignition start is repeated several times, some owners find their own cars start difficult, it takes several times to start, the number of times the car does not need to start a few days will be more, and even if the vehicle starts, it can obviously feel the power decline. Maintenance personnel said that the problem occurred in the way the owner started, and most people were accustomed to inserting the key and immediately ignited it. In fact, this is incorrect. Even the now popular one-button startup system cannot immediately start to fire, otherwise it will hurt the engine. This is due to the fact that the engine is still in a cool state, especially for vehicles with long parking time. The operating parameters of the engine are completely different from the previous day's thermal state. Each sensor needs to be readjusted. If the key is inserted, the engine's operating parameters If it is abnormal raw data, there will be a startup failure or multiple startup failures. Even if it starts successfully, it will cause excessive fuel consumption or engine overheating. Because the computer has an automatic memory function, in the long run, the wrong data will overwrite the correct data, eventually resulting in soft failures such as weak climbing, large fuel consumption, serious carbon deposition, and overheating of the engine. This kind of fault is difficult to find and determine, even if overhauling the engine can not eliminate the fault. How is it that the engineering dump semi-trailer is difficult to start?

Dump semi-trailers are suitable for the transportation of loose bulk cargoes such as coal, ore, and construction materials. The self-unloading semi-trailer, also known as dump trucks and construction vehicles, is composed of a car chassis, a hydraulic lifting mechanism, a power take-off device and a cargo box. According to the chassis carrying capacity, it can be divided into light truck series dumping, small tonnage series dumping and mid-tonnage series dumping. It is widely used in construction engineering, municipal engineering, road construction, sanitation, mine, lime kiln, stone material factory, cement factory, Starch factory, brick factory, fireproof plant, coking plant, phosphate fertilizer plant, chemical fertilizer plant, concentrator, construction team, station, coal yard, bee coal yard, dock and other units of material transfer; can save a lot of manpower, reduce labor intensity. Semi-trailers can be divided into two categories according to their use: One category of heavy-duty and super-heavy dump trucks that are used for off-road transport mainly carry large-scale mines, engineering, and other transportation tasks, and are usually used in conjunction with excavators. The other type of light-to-medium-sized common dump trucks used for road transport mainly carry bulk cargo such as gravel, soil, and coal, and are usually used in conjunction with loaders. 1. The car body adopts side-turning and back-turning self-unloading methods, which can effectively improve the transport efficiency of bulk cargo transported by the loader. 2. The frame and the carriage longitudinal beams are welded with high-quality manganese plates. There are two kinds of crates and rectangles in the container. It has high strength, strong lifting force, good rigidity and toughness, strong bearing capacity, and no permanent deformation. 3、Excellent technology: The main parts are processed by advanced equipment. The stringers are made by automatic submerged arc welding. The assembly machine is used to accurately assemble the axles and leaf springs. Shandong Hongsheng Special Manufacturing Co., Ltd. production standard dump semi-trailer, standard rear dump semi-trailer, light standard side-dump dump semi-trailer, 13-meter side-dump dump semi-trailer, 60 cm back-up dump truck semi-trailer , 12 meters, 11 meters side dump dump semi-trailer, after the load dumped semi-trailer, semi-trailer dump truck.

The correct ignition method is: insert the key to rotate to ACC to stop, wait about 2-3 seconds, Hongsheng vehicle industry makes the main power relay contact firmly contact, let the first part needs to energize the device power; continue to turn the key to ON , And then stop waiting for 6-10 seconds, let the oil pump relay pull, wait for each sensor to adjust the state is completed, the key is turned to START until the engine continuously runs back to the ON position, under the guidance of the computer, automatically adjust the most The location and good parameters finally succeeded in starting the engine. However, for temporary or short-term parking without stopping, just observe that the yellow AAA color indicator light on the instrument panel is extinguished and you can quickly start it .
