Hydraulic buffer main role: as in automated machinery can reduce vibration and noise, the kinetic energy generated by the moving object is converted to heat and released into the atmosphere, in a balanced and effective action will stop the object; the mechanical efficiency increase production capacity, extend the life of the machine and reduce maintenance costs, mechanical action and stable product quality and service, so that operation of the machine safer to avoid accidents, improve the working environment to send staff efficiency, increase their competitive advantage.
