Abstract

The invention relates to a hydraulic oil circuit suitable for tests of multiple kinds of hydraulic components, and belongs to the technical field of hydraulic test. The hydraulic oil circuit suitable for the tests of the multiple kinds of hydraulic components comprises a proportional relief valve, an electromagnetic directional valve, a throttling valve, an electromagnetic ball valve, a proportional directional valve, an electro-hydraulic servo valve, a fine filter, an accumulator, a servo oil cylinder, a pressure sensor, a temperature sensor, a flow sensor, a high-pressure oil source P1, a low-pressure oil source P2, an oil return port PT, an oil drain port PL and a test piece tooling. The invention solves the problems that standard hydraulic test oil circuits have single functions and are low in generality. The hydraulic oil circuit has high automation degree and a strong comprehensive test ability, and can meet the comprehensive test requirements of the multiple kinds of hydraulic components.

Description

technical field [0001] The invention relates to a comprehensive test oil circuit of a hydraulic component, which belongs to the technical field of hydraulic test. Background technique [0002] In order to ensure the reliability of the hydraulic system, it is necessary to conduct experimental tests on the hydraulic components contained in the system. The national test standard has formulated a standard test oil circuit for individual hydraulic components, but the test function is single and the versatility is poor, so it is difficult to adapt to the test of various types of hydraulic components. Complex hydraulic systems often contain various types of hydraulic components, including conventional hydraulic components such as hydraulic pumps, hydraulic motors, hydraulic cylinders, and hydraulic valves. In addition, they may also involve electro-hydraulic servo valves, hydraulic dampers, and valve groups with special functions. Therefore, , it is very meaningful to design a hyd...
