The invention discloses a test system for a gasket in an exhaust emission control device, wherein a first displacement device is connected with a heating device, and the first displacement device is used for driving the movement of the heating device; the heating device is used for heating a gasket to be tested; a first force sensor is connected with the heating device and a control device, the first force sensor is used for testing an expansion force of the gasket to be tested when the gasket to be tested is heated and sending the measured expansion force of the gasket to be tested to the control device; a temperature control device is connected with the heating device and the control device, and the temperature control device is used for receiving a temperature control instruction sent by the control device and controlling a heating temperature of the heating device for the gasket to be tested according to the temperature control instruction; and the control device is used for performing data analysis on the received expansion force of the gasket to be tested to obtain a surface pressure variation curve of the gasket to be tested. The test system provided by the invention for thegasket in the exhaust emission control system achieves performance testing for the gasket.
Description
technical field [0001] The invention relates to the technical field of testing exhaust gas emission control devices, in particular to a testing system for gaskets in exhaust gas emission control devices. Background technique [0002] With the decline of automobile prices and the improvement of the consumption environment, my country's automobile market has maintained an average annual growth rate of more than 10%. However, while automobiles bring convenience to society, they also bring a serious problem, namely, automobile exhaust pollution. . Solving the harm of automobile emissions to environmental pollution has become one of the important topics studied by major automobile manufacturers in the world for many years. One of the important measures is the exhaust emission control device, which converts the harmful gases in the exhaust gas into harmless CO2, N2 and H20 through the honeycomb ceramic substrate coated with Pb and other precious metals, so that the exhaust emissio...
