Self-locking buffer

The LQH-ZN series elastic damping buffer is the latest product of our company and is suitable for iron&steel industry, transport and heavy duty machinery industry widely. Compared with rubber buffer, elastic damping buffer can resist high temperature and corrosion, can suit adverse circumstances, and it has high shocking-resist capability, works stably and has no ageing and failure phenomenon. Compared with traditional pneumatic buffer, air-oil buffer or hydraulic buffer, it is easy to install, its structure is compact, volume is small, weight is light and service life is long, it doesn’ t need daily maintenance. Because it needs fewer sealing links and is not easy to damage, it is more suitable for the high temperature circumstances in which other type of buffers can not work, and it doesn’t need any complicated auxiliary devices, it has no air leak and oil leak phenomenon.

Up to now, The LQH-ZN series buffers made by our company have been used by many famous enterprises successfully. For example DHI.DCW Group CO., LTD., Wuhan Steel company limited, Handan Steel CO., LTD., Shanghai Bao Steel Group, Shanghai Zhenhua Port Machinery, etc.

BASIC PRINCIPLE

Elastic damping buffer take the elastic colloid as medium, by the action of impact, the insertion of piston will result in increase of friction in the colloid. Between the piston-rod and container-wall, the elastic colloid come into being viscous friction by the shearing force, and the faster piston move in，the greater viscous resistance of colloid is.

The colloid is shrinked while the piston is drived in, and inflated when the outside-force reduced or disappeared so that the piston returned back to primary location.

This shows that damping buffer makes full use of compressibility and high viscosity of elastic damping colloid, to convert instantaneous impact energy into elastic potential energy and thermal energy and rapid release.the damping buffer made by using above principle has strong buffering ability.

The dynamic curve prove that elastic damping buffer possess good buffering capability and high energy absorption (up to 95%).

APPLICATION EVIRONMENT

a)Elastic damping buffer can resist high temperature and no ageing, work temperature is -70℃~250℃

b)Work velocity range: 0.5~1.5m/s.it need to be declared if beyond the range.

c)Frequency of the buffer is limited because of poor cooling rate of the elastic colloid. Normally, impact number is no more than ten time per hour.
