| description | Air tightness test is a necessary step in the performance test of electric pneumatic valves. Traditional air tightness test method cannot provide quantitative description of leakage rate, which results in the lack of theoretical data for the reproduction of electric pneumatic valves. In order to solve the problem, differential pressure method to realize the quantitative requirements of air tightness test of electric pneumatic valves is proposed. (Peng et al., 2008) The paper attempts to figure out the relationship between the leakage rate and the differential pressure in ways of modelling analysis. Furthermore, it designs an air tightness test system of electric pneumatic valves based on differential pressure method using MSP430 as controlling core. On the basis of this system, the hardware platform of pneumatic circuit and drive control is constructed. System integration and test is conducted with the use of software. The test proves that this system can realize quantitative description based on qualitative description for testing leakage rate. The automated air tightness test has advantages of low power consumption, quick testing process and stable system. The practicability of this method is obvious. |
