2) Overview
 
Use of the test bench: Damper static performance test bench main function is used to detect the static performance of the damper, such as: low speed friction resistance, blocking speed, post-locking speed, rated load, rated stroke, etc., in addition, static performance test The table can also be used for cold position adjustment of the damper; the damper dynamic performance test bench is mainly used to detect the dynamic performance of the damper, such as: dynamic stiffness (1-33HZ), stiffness ratio, and the like.
In order to better understand the performance and testing requirements of hydraulic damper products, our company has successfully developed 14 static and dynamic performance test benches for hydraulic dampers based on nearly ten years of product production and inspection experience. Eight of them are supplied to nuclear power owners in service. Our company is currently a professional manufacturer with the largest number of damper testers and the most complete functional coverage in China. Our company's hydraulic damper performance test bench design, manufacturing capabilities and test techniques have also highlighted Green as the most professional hydraulic damper manufacturer in China.
