Abstract

The invention provides a test system for a hydraulic rotary joint. The test system comprises an oil tank, a pulse test system, a pressure maintaining test system and a tested workpiece, and the pulsetest system is internally provided with a first energy output oil path, a first control oil path, a pressurizing oil path and a workpiece which are connected in sequence; and a second energy input oilway, a second control oil way and a workpiece are sequentially connected in the pressure maintaining test system. The transient performance and the steady-state performance of the workpiece can be tested respectively through the arranged pulse test system and the pressure maintaining test system, obtained workpiece performance parameters are rich, the requirements of customers for product diversity performance can be met, and in addition, the test system is relatively precise in structural design, stable in work and accurate in test result.

Description

technical field [0001] The invention relates to a hydraulic system, in particular to a testing system for a hydraulic rotary joint. Background technique [0002] After the development of hydraulic testing technology in the past 10 years, it has gradually transitioned from traditional steady-state testing, which only satisfies some necessary working stress and environmental stress simulation, to focusing on dynamic performance, microscopic characteristics and system matching performance. The test equipment has gradually transitioned from manual operation and secondary instruments to a computer-based measurement and control center, with complex system technology for data processing and analysis. [0003] Hydraulic rotary joints are the core components of construction machinery, and their performance and reliability parameters directly affect the use of the whole machine. However, the existing test system has a relatively single test performance and can only test some leaks. O...
