Problems solved by technology

The existing proportional servo valve testing system usually can only statically test the pressure, flow and leakage curve characteristics of the proportional servo valve, but cannot perform high-speed dynamic testing of the displacement of the servo proportional valve, and the tested curve is not smooth and cannot truly reflect Actual Performance of Proportional Servo Valves
At present, there is no dynamic, accurate, comprehensive and operable test system and test method for proportional servo valves

Abstract

The invention discloses a proportional servo valve testing system and a testing method thereof. The proportional servo valve testing system comprises a hydraulic system, an electric control cabinet and an industrial personal computer. The industrial personal computer comprises America LABVIEW software, Germany SIEMENSS7-300PLC software and a board card PCI. The electric control cabinet and the industrial personal computer control the hydraulic system together. The board card PCI comprises PCI1710U and PCI1720U and is connected with a PCI of the industrial personal computer, and the industrial personal computer is connected with a DP interface of the Germany SIEMENSS7-300PLC software through a CP5611 interface. By means of the system and the method, an accurate servo valve dynamic characteristic curve is provided and can be used for servo valve manufacturer performance testing and can also be used for testing after the servo valve maintenance company finishes maintenance, especially for some imported servo valves. The system can reduce maintenance cost.

Description

[0001] technical field [0002] The invention relates to the technical field of mechanical engineering, in particular to a proportional servo valve testing system and a testing method thereof. Background technique [0003] In the field of mechanical engineering technology, the precision of products requires higher and higher control precision, and various servo valve control systems have been used more and more widely. Proportional servo valve control system is a typical high-precision adjustment control system, and it is often the core guarantee technology for high-quality and high-yield products in a production line. The existing proportional servo valve testing system usually can only statically test the pressure, flow and leakage curve characteristics of the proportional servo valve, but cannot perform high-speed dynamic testing of the displacement of the servo proportional valve, and the tested curve is not smooth and cannot truly reflect Actual performance of proport...
