【正文】 ing way with a shock absorbing instead of steel springs superposition, so its advantages of rigidity, ageing resistance stable mechanical property shown in practice are beyond parison. Excellent properties of elastic damping materials enable disc shock absorber to satisfy big load shock absorbing requirement at very small volume so that effectively save design space. Its these good properties are also suitable for the anchor bolt shock absorbing etc. situations. High energy damping buffer Basic principle By the action of dynamic applied force, the fast insertion of piston will result in steep increase of friction between piston and damping material and piston rod is decided by moving speed, both are in direct proportion. The friction between solid sealing parts is decided by internal pressure, ., the larger internal pressure is, the larger friction is (the pressure is produced by pressing the volume of elastic material chamber). This shows that high energy damping buffer makes full use of pressibility and high viscosity of elastic damping medium, it converts instantaneous impact energy into elastic potential energy(produced by pressing medium)and thermal energy(produced by friction)and rapid release. High energy damping buffer made by using above principle has strong buffering ability, and its volume is small, weight is light, its buffering energy is 3 times of which rubber buffer had at same volume, the highest energy absorptivity can reach 85%. The advantages of products Compared with rubber buffer, high energy damping buffer can resist high temperature and corrosion, can suit adverse circumstances, it has strong rigidity and high shock strength, it works stably and has no ageing and failure phenomenon. Compared with traditional pneumatic buffer and air oil buffer or hydraulic buffer, it is easy to mount ,its structure is pact, volume is small, weight is light and service life is long, it doesn’t need daily maintenance. Because it has fewer sealing links and is not easy to damage, it is more suitable for high temperature circumstances in which pneumatic buffer and hydraulic buffer can not work, and it doesn’t need other plicated auxiliary devices, it has no air leak and oil leak phenomenon, it works stably and reliably. Scope of application High energy damping buffers have been widely applied in iron＆ steel industry and heavy machinery industry, such as: buffer for baffle plate and loop in rolling mill, for adjustable end stop, for limits of soaking hood and various moving machinery, lifting machinery etc. many places where buffering and guard are needed, the use result is very ideal, they can increase collision safety coefficient of equipment with the highest limit at a limited design space and guard the main equipment well. 。 特性 : (1) 高粘性 (2) 強壓縮性 (3) 良好的熱穩(wěn)定性 (4) 特殊的化學惰性 (5) 無老化現(xiàn)象 附錄
