Abstract


The hydraulic cylinder is an energy conversion of the hydraulic actuator , which hydraulic energy into linear motion of the mechanical work, which is the actuator of the hydraulic system . With the continuous development of China 's science and technology , hydraulic cylinders, hydraulic drive and control more and more widely , the function of the hydraulic cylinder is constantly develop and utilize . At the same time, user requirements for the performance of the hydraulic cylinder is getting higher and higher , the hydraulic cylinder testing equipment and methods seriously hampered the improvement of production technology of hydraulic cylinders , the improvement and enhancement of hydraulic cylinder testing equipment and methods , introduced a new type of hydraulic cylinder type test station to become an urgent problem . Firstly, in access to a large number of domestic and international data on the basis of , the content of domestic and international development of the hydraulic cylinder test rig , the significance of the study of the test-bed and national standards for pilot projects . Secondly, the need for actual production , the article describes the system function of the hydraulic cylinder type test station analysis , structural analysis , and computer control system can achieve automatic intelligent control . Finally, the type of the hydraulic cylinder test Taichung proportional relief valve pressure control system loading characteristics , and its pressure control characteristics . This paper discusses a new type of integrated hydraulic cylinder - type test , type testing and factory test of the specifications of the hydraulic cylinder and additional 70MPa ultrahigh pressure test . The test rig can be up to six hydraulic cylinders synchronization test , and also conventional ultra-high pressure , high temperature , three test can be carried out simultaneously . In addition , the test-bed for remote stepless voltage regulation , composite governor , proportional loading , stable commutation , automatic discharge of oil , the intelligent automatic control of the trip non -contact measurement , the oil temperature automatic control system test . So that the test rig to comprehensively improve the accuracy , stability and reliability of the performance testing of the hydraulic cylinder , reduce labor intensity , improve production efficiency , and provide a solid foundation for the improvement of the level of production technology of hydraulic cylinder , hydraulic cylinder production detection has major significance and practical significance .
