Computer test control system for pressure alternating test of air-air intercooler

Abstract

The invention relates to a computer test control system for pressure alternating test of an air-air intercooler. The computer test control system comprises an industrial personal computer, a data collecting module, a temperature sensor, a pressure sensor, a touch screen and a programmable controller, wherein the industrial personal computer is connected with the display screen and the programmable controller, the programmable controller is respectively connected with the data collecting module and the touch screen, the data collecting module is respectively connected with the temperature sensor and the pressure sensor, the computer test control system collects one to three circulation data of an air circulating system at the set time interval, the temperature, the pressure, the set value, the real-time operation curve, the wave form and the warning signal during the real-time operation of the air circulating system are displayed on the display screen, and values are regulated on the touch screen for measuring the fatigue resistance intensity of test pieces. Compared with the prior art, the computer test control system has the advantages that the structure design is novel and practical, the operation and the maintenance are convenient, the safety performance is higher, and the like.

Description

technical field [0001] The invention relates to a computer measurement and control system for pressure alternating tests of air-air intercoolers, in particular to a computerized measurement and control system for air-air intercoolers that can simulate the fatigue resistance of heat exchange equipment under actual working conditions Computer measurement and control system for pressure alternating test. Background technique [0002] Air-air intercooler of internal combustion engine is an indispensable part in high-end cars or large locomotives. Its performance directly affects various indicators such as whether the internal combustion engine is running normally, energy consumption, and exhaust emissions. The pressure alternating test is the necessary equipment to ensure the quality of the air-air intercooler. At present, there is no unit in China that can meet the technical performance curve graph proposed in the project index, and most of them are zigzag, which cannot meet th...
