The Designing And Developmnent Of The Piston Compressor’s Displacement Test System

This paper describes the design and development of the test system for the exhaust of the piston compressor, and discusses the design and Realization of the system. The working principle and the system testing mechanism of piston compressor are described. The overall design scheme of the hardware and software of the system is given, and the realization method of the function of the system is discussed. The main research contents and conclusions are as follows:(1) test mechanism analysis. By analyzing the working principle of the piston compressor, the concept of the performance parameters of the compressor is given, and the test method is given.(2) the overall design scheme of the software and hardware. The overall design scheme of the test system for the exhaust volume of piston compressor is put forward, which includes the function design of the system, the overall structure design of the system, hardware design and software program design.(3) functional implementation method. The realization process of the data acquisition and real-time testing function of the testing system is studied. The method to solve the problem is presented. The hardware and software program are presented. The selection of hardware and software are discussed. Then, the test of the performance parameters and the realization process are described.(4) case test analysis. The test system of the piston compressor’s exhaust quantity is tested. The experimental calibration method of the temperature sensor and micro pressure sensor is presented. The performance parameters are measured and the specific steps and the main steps are described. The error analysis is carried out based on the test data. The results show that the system has higher accuracy.
