Aluminium round discs are also known as an aluminum round disc, referring to aluminum wafers made of aluminum as the main raw material and mixed with other alloying elements. The aluminum round disc is a round type obtained by embossing an aluminum ingot, and is divided into different grades, specifications, and states according to the use. There is a certain amount of solid metal particles in the aluminum disc. When we use aluminum discs, sometimes the surface will be damaged. And what are the causes?
1. When the metal flows through the working belt during the kneading process, a large amount of segregation floating objects or strong metal particles adhere to the surface of the working belt on the surface of the aluminum round disc, which may cause scratches on the surface of the aluminum wafer.

2. There is any debris on the work belt during work, so that the surface of the work belt is injured during the kneading and aluminium round discs are scratched.
3. The speed is too fast to form aluminum disc bumps;
4. The aluminium round discs collide with each other or knead to form damage during transportation.
Aluminum round disc pieces and aluminum alloys are among the most economical materials available today. The current production and use of aluminum is second only to steel, making it the second largest metal for human applications, and the resources of aluminum are very rich. Aluminum wafers and aluminum alloys are widely used in the manufacturing industries of airplanes, automobiles, trains, and ships. Pure aluminum is very soft with good ductility, and can be drawn into filaments and rolled into foil, used in the manufacture of wires, cables, the radio industry, and the packaging industry.

Подключение электродвигателя ленточного конвейера
Каждое оборудование нуждается в техническом обслуживании во время эксплуатации, а так же сама эксплуатация требует правильного подхода. Немаловажную роль имеет способ подключения. В таком оборудовании как ленточный конвейер присутствуют различные модификации, а области их применения многообразны. Они имеют постоянный крутящий момент, а момент сопротивления различен и возрастает со степенью загруженности оборудования. В этих условиях подключение электродвигателя ленточного конвейера нужно осуществить правильным образом.
Пуск прямой подачей напряжения
График включения компрессора прямой подачей напряженияГрафик включения компрессора звезда-треугольникГрафик включения компрессора при системе плавного пуска
Что бы запустить такое оборудование, стартовый крутящий момент должен превышать или быть равен номинальному крутящему моменту электродвигателя. Стартовый крутящий момент при таком пуске в 1,5-2,5 раза превышает номинальный крутящий момент электродвигателя. По этой причине между лентой конвейера и ведущим роликом возникают проскальзывания. Редукторы и шарниры системы подвергаются внушительным перегрузкам. В результате этих воздействий срок службы оборудования значительно сокращается. В некоторых случаях, что бы снизить показатель стартового крутящего момента применяют гидравлические приспособления, но цена на эти опции высока, а процесс обслуживания достаточно трудоемкий и сложный. http://www.uesk.org/katalog/elektrodviga...is2e/56a2/ Включение методом «звезда-треугольник»
Схема включения электродвигателя «звезда-треугольник» неприменима к такому оборудованию как конвейер. Поскольку на валу электродвигателя при его пуске присутствует нагрузка а значение момента сопротивления равно номинальному крутящему моменту при старте, такое включение может вывести мотор из строя.
Система плавного пуска
При применении этого подключения стартовый крутящий момент снижается до необходимого значения, достаточного для запуска ленты конвейера. Этот метод включения можно настроить таким образом, что бы он максимально соответствовал значению, которое необходимо для запуска оборудования. В результате использования этого метода при включении электродвигателя, существенно снижается механическая нагрузка на механизмы системы, а ремни в процессе пуска не проскальзывают. В результате расходы на эксплуатацию оборудования снижаются. Пусковой ток в результате такого запуска системы будет в 3-4 раза превышать номинальный ток электродвигателя. Если конвейер загружен максимально или если его лента слишком длинная, выбирайте систему плавного пуска под большой нагрузкой.
Рекомендуемые настойки:
• Время включения: 10 секунд
• Время остановки: 0 секунд
• Начальное напряжение: 40%

Under normal circumstances, lithium battery aluminum foil as a positive electrode collector, commonly used aluminum foil is a series of pure aluminum foil, including 1060 aluminum foil, 1050, 1235 and other grades, the state is O, H14, H18, H24, H22, thickness of 10 to 50 microns between. The choice of battery aluminum foil is very important and has a great impact on battery performance. Among the total procurement costs, cathode material procurement costs account for 30%, and anode materials account for 20%.
The surface quality of the battery aluminum foil has certain requirements, including: 1 The surface of the aluminum foil is uniform in color, clean, and flat. 2 The surface of the aluminum foil has no rolling defects such as creases, spots, and bright lines; there are no pinholes and corrosion marks. 3 The surface of the aluminum foil is oil-free, has no serious oil odor, and no oil spots are visible to the naked eye. 4 Surface tension test is not less than 32 dynes. Lithium battery aluminum foil anode aluminum foil has no special requirements on the performance of aluminum foil.
In new energy vehicles, lithium batteries play an important role. On the one hand, the positive electrode of the lithium battery is aluminum foil, which can reduce the weight of the car itself. On the other hand, the reduction in body weight can also increase the cruising range of new energy vehicles.

Due to the different performance of the fins, the fin stock are mainly divided into two categories: plain aluminum foil and hydrophilic coated aluminum foil.
Aluminum foil (fin stock) refers to aluminum foil which is rolled and annealed and has no surface treatment. It is mainly used in low-grade split air conditioner outdoor units and window machines;
Hydrophilic coated aluminum foil (finned stock) refers to an aluminum foil deep-processed product coated with an anti-corrosive coating and a hydrophilic coating on plain aluminum foil. The hydrophilic coated aluminum foil surface has strong hydrophilicity and is used on air conditioners to optimize the ventilation effect of the heat exchanger, thereby increasing the heat exchange rate by 5%. In addition, the hydrophilic coated aluminum foil also has other advantages such as anti-corrosion, anti-mold, no odor, and is mainly used for medium and high-grade and export air-conditioning.
