Research Of Sealing And Leakage Of Reciprocating On The Hydraulic AGC Servo Cylinder

Hydraulic seal is a very complex mechanical parts.Probably from the 1930s began,reciprocating seals on hydraulic engineering research has been initial progress.AGC hydraulic servo cylinder is rolling system electro-hydraulic servo system and proportional system of actuators,its role is very important.By servo cylinder,in order to achieve arbitrary control of the direction of movement of the load,position,speed,etc.As the hydraulic system is a key part of the circuit,so when it fails,debugging and troubleshooting very difficult,often due to inability to timely troubleshooting and forced shutdowns,and the hydraulic cylinder seal problem is the failure of major the reason.In this paper,laboratory conventional hydraulic AGC servo system experimental study,pressurized leakage test,to receive the experimental and theoretical data,and provides an overview of experimental and theoretical studies on nearly a decade of analysis from the relevant discussion Publications over 200 of the most influential literature.The main issues discussed included the design of hydraulic reciprocating seal,materials,experimental methods,theoretical research,fluid dynamics elastic lubrication,solid contact mechanics,hydraulics sealing performance issues and optimize programs.At present,the fuel tank has been widely used in various devices.With the rapid development of electro-hydraulic servo technology,robotics,aircraft tail wind tunnel support mechanism and metallurgical equipment are increasingly adopting servo cylinder,the servo system requires a good dynamic and static performance.Therefore,the design precision servo cylinder,ensure operational performance,increase service life,has important significance.Most are non-standard servo cylinder,this cylinder is designed for servo servo cylinder HAGC metallurgical industry rolling mills.Servo cylinder performance and dynamic and static stiffness largely depends on the cylinder seal.Therefore,the study of sealing and leakage of hydraulic AGC servo-hydraulic cylinder reciprocating mofion is to design high-precision servo-hydraulic cylinders important issue.
