Vehicle high temperature and high humidity test vehicle anti-aging performance
On test benches in the automotive industry, accurate temperature simulation is critical. From the time of the test, the air temperature in the test chamber has always been maintained at 45 ℃, which is equivalent to the hottest area of the Flaming Mountains in Turpan, Xinjiang, China. Ultra-high temperature environments cause all automotive components, from control electronics to gaskets and load-bearing elements, to experience severe temperature fluctuations that, in addition to mileage, stress materials and circuits. Temperature control systems are mainly used in two ways: they can simulate external environmental conditions in a climate chamber or replace internal systems, such as the cooling circuit of an engine. For example in a vehicle, a coolant is supplied to the sample.
IC test conditions for locomotives: -40℃~125℃, wind blowing, sun exposure, high vibration;
Instrument panel operation test test conditions: -40℃~85℃;
Motor controller test conditions: operating test temperature: 40 ℃ ~ 110 ℃;
Satellite positioning (GPS) Test conditions: high temperature operation test temperature: 85℃; low temperature operation test temperature: -40℃;
Compound vibration: -40℃~80℃;
The only area in my country that meets the ambient temperature tested by these projects is Turpan, with a large temperature difference between day and night. Shipping is a big project. Obviously the best solution is for the test house to have temperature simulation system equipment.
Our refrigeration and heating temperature control flow system KRY series equipment can be flexibly connected to other test platforms. The system is controlled by Siemens PLC, and the electrical control part can complete all actions without manual operation, which not only avoids human operation errors but also improves the The accuracy of the test results has a great advantage in endurance testing. The temperature range is -40℃~+100℃, which can be extended to +135℃ according to the actual situation, and the temperature control accuracy is plus or minus 0.5℃. The equipment can control the flow and pressure independently while controlling the temperature, and different customized solutions are required for simultaneous control.
