Test System For Hydraulic Gear Wheel Pump Performance Parameter Based On Visual C++

This thesis has finished the design of the System of Computer Aided Test for Hydraulic Gear Wheel Pump, and the design is based on Visual C++. Basing the National Standard related to the test and the condition existing in lab, according to the principle of hydraulic pump and the design criterion of hydraulic system and test system, using precise theory analyzing and integrating exactly experiment, the system is designed. This system is mainly made up of hardware and software, two major parts. It not only can gather and deal whith the test data but also can control the output pressure and the rotational speed of the hydraulic pump. The hardware include pulling, observing and controlling, hydraulic pressure three main parts, and the core of it is industry computer. The soft ware of this system is constructed by utilizing Visual C++ in Windows operating system. The soft ware can observe and control the whole system through the hardware. Analyzing the test result, forming the form and drawing the curve is also can be done by the software. Finally, for the sake of systematic stability the thesis discussed how to resist the interference by hardware and software.
