Winter can not start the diagnosis of three parts need to pay attention to inspection
Why do you have a car? The map is the convenience of travel, especially in the winter. In the cold winter months, when you open the door and open the car, you accidentally discover that the car cannot start.
Diagnosis Part I: Battery
The weather turned cold, winter has arrived, and the most direct impact of the winter on the owners of the North is to start the car. At low temperatures, the battery power will be greater than the temperatures in other seasons. This is like the fact that many battery-powered devices in winter use a feeling of insufficient battery power.
Solution: Zhang Naiqi, technical director of Shenyang Zhongba Subaru Hutai Store, said that winter battery will also be affected by the temperature and make the electric capacity lower. Especially when some car owners lose their battery capacity due to business trips or not driving for a long time, they will lose their battery capacity. Will not start up, usually the battery life is 2 years, if the battery is maintained, the service life can be extended to 3 years.
If the battery of some vehicle owners does not have a shelf life, and such a situation occurs, you can only find friends or service personnel of the 4S shop to charge your car battery through the battery or power supply of other vehicles. After the battery is restored, it is best to go to the 4S shop to check the battery to see if there is a fault.
Diagnostic site II: exhaust pipe
In winter, many owners are relatively lazy and will drive for shorter distances. Sometimes due to the short distance near the exhaust pipe, water vapor may be generated due to the temperature difference between hot and cold. Freezing of the exhaust pipe may result in unsmooth start-up of vehicle exhaust. .
Solution: A technician in a car repair shop, Master Zhao, said that the solution to this type of situation is very simple. To solve the ice problem, you must first think of ways to melt the ice in the exhaust pipe, such as pushing the car to a warmer place. , Or use a hot water bottle to melt the ice in the exhaust pipe, then start the car, and do not use the fire to evaporate the exhaust pipe.
If you want to solve this problem completely, it is best for the owner to run a high-speed or long-term car and thoroughly melt and dry the ice and water vapor in the exhaust pipe with high heat.
Diagnostic Site 3: Engine Oil
The car is not used for a period of time, especially in the winter, it is easy to make some of the oil in the car go bad or freeze and block the oil circuit, which makes the engine resistance increase and the starting difficult.
Solution: The peak of a car maintenance shop manager said that in the winter, the car is mainly to the 4S shop to check whether the oil of his car is suitable for winter use, then it must be replaced in time.
For example, it is appropriate to select 5W~40 engine oil for an outside air temperature of -30°C; and for an outside temperature range of ~25°C to 30°C for a 10W-30 engine oil. The heat resistance and cold resistance of 5W~40 are better than 10W~30, but the price will be relatively higher. The owner can select the engine oil according to the local temperature.
Stamping Parts:
The processing method for stamping and forging are plastic processing (or pressure processing), forging stamping blank collectively. Is hot-rolled and cold-rolled steel sheet and strip. The world of steel, 60 ~ 70% is the plate, mostly made by stamping products. Automobile body, chassis, tank, radiator, boiler drum, vessel shell, electric machine, electric iron core silicon steel sheet are stamping processing. Instruments, household appliances, bicycles, office machinery, household utensils and other products, there are a large number of Stamping Parts stamping. Is powered by conventional or special punching equipment, make sheet metal in the mold directly affected by the deformation force and deformation, thus A certain shape, size and performance of the product parts production technology. The sheet metal, mold and equipment are the three elements of stamping. Temperature divided by stamping hot stamping and cold stamping. The former is suitable for high deformation resistance, sheet metal plasticity is poor; the latter was carried out at room temperature, is commonly used in stamping method the sheet metal plastic processing. It is (or pressure processing) one of the main methods, but also forming part of materials engineering. Stamping mold called stamping die, or die. The die is the material (metal or non-metal) batch processing into the special tool stamping. Die is of vital importance in the in the press, did not meet the requirements of the die, it is difficult to carry out production batch stamping die; no advanced, advanced stamping process can not be achieved. The stamping process and die, stamping equipment and stamping materials to constitute three stamping processing Only when they combine with each other can they get the stamping parts.
WHY Stamping:
Stamping parts and castings, forgings, a thin, uniform, light, strong character. Stamping can be produced from other methods is difficult to manufacture with stiffeners, stamping parts stamping rib, rolling or burring of the workpiece, to improve its rigidity. Because of the use of precision molds, workpiece precision, and high repetition accuracy, specifications, can punch a hole nest, boss. Cold stamping generally no longer cutting machining, or only a small amount of cutting. The hot stamping precision and surface state below the cold stamping, but still better than the casting, forging, machining less.
(1) Stamping processing is of high production efficiency, convenient operation, easy to realize mechanization and automation. This is because the stamping dies and stamping equipment rely on to complete the processing, ordinary press trips per minute up to dozens of times, high pressure per minute up to hundreds or even thousands of times, and each press stroke you may get a red piece.
(2) The stamping die ensure the dimension and shape precision stamping parts, and generally do not damage the surface quality of stamping, and die life is generally longer, so the stamping quality, good interchangeability, "as like as two peas" feature.
(3) Stamping can press the processing size range is large, complex shape parts, such as a small clock stopwatch, large car rails, covering parts, stamping and material hardening effect of cold deformation, punching strength and stiffness are higher..
(4) Stamping generally without cutting scrap generated, material consumption is less, and no other heating equipment, which is a kind of material saving, energy saving and processing, lower the cost of stamping parts.
Category:
Stamping is mainly according to the process of classification, can be divided into separation process and the forming process of two categories. The separation process also known as blanking, its purpose is to make the stamping parts along the contour line must be separated from the sheet, and guarantee the quality of the separation section (Table 1). The forming process is designed to make sheet metal in broken slab under the condition of plastic deformation, the workpiece into the required shape and size. In the actual production, often a variety of integrated process applied to a workpiece. The blanking, bending, shear, tensile, bulging, spinning, correction is the main stamping process of several.
Mainly speaking,based on the three different material,we can make steel stamping farts,copper alloy stamping parts and aluminium alloy stamping parts.
