Working cycle: The conversion of thermal and mechanical energy of the internal combustion engine through the piston in the cylinder, continuous intake, compression, power and exhaust processes. The process of each machine is called a work cycle.
Piston stroke: The minimum linear distance between the upper and lower dead centers is called the stroke of the piston (or the stroke of the piston). The minimum linear distance between the center of the connection between the crankshaft and the big end of the connecting rod to the center of rotation of the crankshaft is called the rotation of the crank. radius.
Top dead center and bottom dead center: When the piston moves in the cylinder, the highest point is called top dead center (or top dead center), and the lowest is called bottom dead center.
Working volume: The piston moves from top dead center to the next point, called cylinder volume (piston displacement).
Compression ratio: air fills the cylinder, the total volume occupied by the cylinder will occupy the total cylinder volume. The larger the gas compression ratio, the more the gas is compressed when the piston moves, and the higher the temperature and pressure of the gas, the internal combustion engine. The efficiency is also higher.
Aluminum oxide flap discs are made by Aluminum oxide coated cloth, one kind of the flap discs or power flex discs. ALO flap discs have the advantages of grinding discs and fiber discs, making it easier for grinding and polishing disposable, reducing the work process and lower the grinding cost.
Abrasive grains for ALO Flap Disc is Aluminum oxide. ALO flap discs are widely used in grinding, polishing and deburrnig of metals and non-metals; metals includes general metals, carbon steel, alloy steel, casting iron, etc.
Flap discs have the features of quick speed, high efficiency, synchronous consumption, strong grinding force, fast heat disspation and good performance.
