The invention discloses a testing system for a hydraulic ram. The testing system for the hydraulic ram comprises a hydraulic power supply and a main testing unit, wherein the main testing unit comprises a first three-position four-way electromagnetic directional valve, a second three-position four-way electromagnetic directional valve, a second overflow valve, a third overflow valve, a third throttle valve and a fourth throttle valve; the hydraulic power supply is connected to the port a of the first three-position four-way electromagnetic directional valve; the port c of the first three-position four-way electromagnetic directional valve is communicated to the port a of the second three-position four-way electromagnetic directional valve; the port c of the second three-position four-way electromagnetic directional valve is communicated with the inlet of the second overflow valve and the third throttle valve. The testing system disclosed by the invention can be specially used for testing the hydraulic ram, and has the advantages that testing is convenient, and the testing efficiency is high.
Description
technical field [0001] The invention relates to a hydraulic test bench, in particular to a hydraulic cylinder testing system capable of testing hydraulic cylinders. Background technique [0002] At present, hydraulic technology is widely used in various fields. The produced hydraulic components and equipment need to be tested, such as hydraulic cylinders, hydraulic motors, and some hydraulically driven wind power. However, at present, the test of the hydraulic cylinder needs to be installed on the actual equipment to complete the test, which is very inconvenient, and the testing efficiency of the hydraulic cylinder is relatively low. [0003] Therefore, it is necessary to develop a hydraulic cylinder testing system that is convenient for testing and has high testing efficiency. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a hydraulic cylinder testing system to overcome the shortcomings of the prior art. [...
