Development of Testing System for Micro Two-dimensional Hydraulic Pump Based on Virtual Instrument

The micro-sized hydraulic components are the key components in aerospace, robot and other high-end equipment. Its development is one of the key research directions in the field of fluid drive and control. In order to test the performance index of the new-type micro-sized 2D hydraulic pumps, taking micro-sized 2D piston pump as the test object, adopting the method of parallel energy recovery and multi-machine synchronous test, and designing the performance test system of micro-sized 2D hydraulic pump based on LabVIEW platform. The test system takes the data acquisition card as the middle end of the signal to carry out high-precision data acquisition and control signal output. The modular design method can shorten the development cycle of the test software and facilitate the expansion of functions. The system realizes real-time monitoring and remote adjustment of test parameters. The system can complete various performance tests such as displacement verification test, efficiency test and seal inspection test, and has the functions of automatically generating characteristic curve, saving test data and chart information after the tests, and making test report, etc.
