What are the problems of the shock absorber of the nodular casting factory

The damping function of the shock absorber is to convert the energy of shock into heat energy. If the gray iron supplier suspends to produce the large range movement, the relative shock absorber gray iron castings wholesale will also produce the quite big resistance to restrain it, this resistance comes the shock absorber piston will put the oil pressure into the small valve, so it will turn the resistance into the heat. The heat generated inside the shock absorber warms the damping oil the viscosity of the oil becomes thinner after heating (the reaction is similar to that of engine oil). After thinning, the damping oil will reduce the resistance through the oil valve reduce the damping force, which is called "shockfade". 1438076743690678 [1]. JPG to avoid damping decay, it can be improved by increasing the capacity of shock absorber damping oil. Therefore, the so-called high-performance shock absorbers usually have large tube diameter large damping. Another problem of the shock absorber is the bubble problem of damping oil. When the shock absorber is actuated, the piston will stir the damping oil to produce bubbles, which will cause the loss of damping. In order to fight against bubbles, in addition to using better damping oil, manufacturers usually fill high-pressure gas to reduce the generation of bubbles. The most representative product is bilstein. Bilstein's product has a unique design, which has a "gas chamber" to resist the generation of bubbles, which is like using high-pressure to resist you The boiling point is proportional to the pressure. In addition, the air chamber also has cooling effect on the column bolt, because the column bolt can obtain cooling effect when exposed to air. The problem of oil leakage caused by poor oil seal is one of the main causes of shock absorber damage, which is directly related to the "durability" of shock absorber, so the more expensive shock absorber usually has better oil seal shock absorber accessories.
