We often see vehicles covered with various propaganda signs on the road. This is the LED advertising vehicle . Many vehicle owners today do not understand the daily maintenance and maintenance of LED advertising vehicles, which greatly reduces the lifespan of the vehicles. It is easy to cause failures. What are the daily maintenance items for LED advertising vehicles ?
Before the advertisement vehicle is operated, the driver needs to check whether the door of the LED screen box has been fully locked, whether the LED screen has been fully landed, and it is also required to check whether the welding site of the LED screen site plate and the steel plate lifting lug is There is no existence of cracks, tire pressure is not normal and so on. Only after doing these inspections can you begin your daily tasks.
LED advertising vehicles in the process of driving, the speed is best to control within 30 kilometers per hour, and the follow-up staff also need to be on the move every time to monitor the advertising vehicle, found that when the road is uneven, need to be timely Remind the driver to slow down.
In the LED advertising vehicle operation, the middle distance between the tail of the tractor and the front end of the media car can not be less than one meter, otherwise, when turning, the tail of the tractor will damage the outer casing of the media car, and the short distance can be manually moved. Do not use towing traction rods with the tow bar mounted on the truck.
When the advertising vehicle arrives at the designated working site, it is first necessary to put down the four supporting feet of the car and adjust the length and tighten it with the ground. In the case of extremely strong winds, it is necessary to prevent advertisements from being advertised. Can't raise the car's screen. When the advertising vehicle raises the screen, it is forbidden that the worker will put his head into the space below the screen and the gap of the chassis so as to avoid accidental production.
If the LED advertising vehicle malfunctions, professional people are required to perform maintenance. At the same time, the screen needs to be raised after the screen is repaired, and a support rack for preventing sudden drop is also required inside the elevator. Before the start of the LED, the ground needs to be grounded. Wire is connected to prevent leakage.
Aluminum roll is widely used in electronics, packaging, construction, machinery and other aspects, our country's aluminum roll production enterprise is more, the production technology has caught up with developed countries, according to the metal elements aluminum roll contains are different, aluminum roll can probably be divided into 9 big categories, that is, can be divided into 9 series, are roughly introduced:
1000 series
On behalf of 1000 series aluminum plate is also known as pure aluminum plate, in all series 1000 series belong to a series containing the most aluminum. Purity can reach more than 99.00%. Because it does not contain other technical elements, the production process is relatively simple and the price is relatively cheap. It is the most commonly used series in conventional industry at present. Most of the 1050 and 1060 series are in circulation in the market. The minimum aluminum content of 1000 series aluminum plate is determined according to the last two Arabic digits of this series, such as the last two Arabic digits of 1050 series is 50. According to the international brand naming principle, the aluminum content must reach more than 99.5% for qualified products. China's aluminum alloy technical standard (gB/T3880-2006) also clearly stipulates that the aluminum content of 1050 can reach 99.5%. In the same way, the aluminum content of 1060 series aluminum plate must reach more than 99.6%.
2000 series aluminum plate
On behalf of 2A16 (LY16) 2A06 (LY6) 2000 series aluminum plate is characterized by high hardness, among which the content of Copper is the highest, about 3-5%. 2000 series aluminum plate belongs to aviation aluminum material, is not often used in conventional industry. Our manufacturers of 2000 series aluminum plate are few. The quality cannot be compared with abroad. Korean and German manufacturers mainly supply the imported aluminum sheet. With the development of Chinese aerospace industry, the production technology of aluminum plate in 2000 series will further improve.
3000 series aluminum plate
Indicates 3003 3003 3A21. It can also be called rust-proof aluminum plate. Our production process of 3000 series aluminum plate is excellent. 3000 series aluminum plate is made of manganese element as the main component. The content is between 1.0 and 1.5. It is a series with good rust prevention function. Commonly used in air conditioning, refrigerator, car under humid environment, price higher than 1000 series, is a more commonly used alloy series.
4000 series aluminum plate
On behalf of 4A01 4000 series of aluminum plate belongs to the high silicon content of the series. The silicon content is usually between 4.5 and 6.0%. It belongs to building materials, mechanical parts, forging materials, welding materials; Low melting point, good corrosion resistance Product Description: With heat and wear resistance
5000 series
Stands for 5052.5005.5083.5A05 series. 5000 series aluminum plate belongs to the more commonly used alloy aluminum plate series, the main element is magnesium, the magnesium content is between 3-5%. Also known as aluminum magnesium alloy. The main characteristics are low density, high tensile strength and high elongation. The weight of aluminum magnesium alloy is lower than that of other series under the same area. Often used in aviation, such as aircraft fuel tanks. It is also widely used in conventional industry. The processing technology is continuous casting and rolling, which belongs to the hot rolled aluminum plate series, so it can do oxidation deep processing. In our country 5000 series aluminum plate belongs to one of more mature aluminum plate series.
6000 series
Represents 6061 mainly contains magnesium and silicon two elements, so concentrated the advantages of 4000 series and 5000 series 6061 is a cold treatment aluminum forging products, suitable for corrosion resistance, oxidation requirements of high applications. Good usability, excellent interface characteristics, easy coating, good processing. Can be used in low pressure weapons and aircraft joints.
General characteristics of 6061: excellent interface characteristics, easy coating, high strength, good usability, strong corrosion resistance.
Typical uses of 6061 aluminum: aircraft parts, camera parts, couplers, Marine fittings and hardware, electronic fittings and joints, decorative or various hardware, hinge heads, magnetic heads, brake pistons, hydraulic pistons, electrical fittings, valves and valve parts.
7000 series
Represents 7075 mainly contains zinc. Also belongs to aviation series, is aluminum magnesium zinc copper alloy, heat treatment alloy, belongs to super dural alloy, has good wear resistance.7075 aluminum plate is stress-relieved, after processing will not deformation, warping. All super thick 7075 aluminum plate by ultrasonic detection, can ensure that no sand holes, impurities.7075 aluminum plate has high thermal conductivity, can shorten the molding time, improve the work efficiency. 7075 is a high hardness, high strength aluminum alloy, often used in the manufacture of aircraft structure and futures. It requires high strength, corrosion resistance of high stress structural parts, mold manufacturing. Rely on import basically, our country production technique still need to be improved. (The company once had a foreign company proposed that the domestic 7075 aluminum plate annealing is not uniform, the surface and internal hardness of aluminum plate is inconsistent)
8000 series
The more commonly used 8011 belongs to other series. In my memory, aluminum plate is mainly used for bottle caps. It is also used for radiators, most of which are aluminum foil. It's not very common.
9000 series
Belongs to the standby series, so developed technology, in order to cope with the appearance of aluminum plate containing other alloying elements, the international aluminum plate Federation shows that 9000 series for the standby series, waiting for a new variety to appear to fill the gap of 9000 series.
