Abstract


With the rapid development of the electronics industry , more and more stringent control of suspended particles in the electronics industry production environment , making the air filtration industry faces enormous opportunities and challenges . Current domestic efficient, ultra - high efficiency filter performance test national standard sodium flame method , oil mist law due to various defects can not meet the actual needs of the development , it is necessary to refer to relevant international standards for the development of new and efficient ultra - high efficiency air filter performance detection system to solve the current situation of the domestic high efficiency air filter quality testing methods are backward . The detection system to the European standard EN1822 for the program , and at the same time learn from the Japan JIS B 9908 standard , and the United States IEST standard , full build efficient ( super efficient ) filter efficiency test and scan test station . The entire system can measure the most penetrating particle size efficiency and local efficiency high efficiency air filters . Given the degree of automation of the foreign high efficiency filter detection system is higher than the domestic certain level , the automatic control system and the system of the testing station developed by the introduction of automated instrumentation stepper motor control software , the detection of high degree of automation of Taiwan The full-featured . The detection system on the basis of previous work to redesign the scanning structure and scanning procedures , the usefulness of the scanning station . This article focuses on the production of the inspection station , equipment selection, automatic control system design . Through the development of new efficient filter performance testing laboratory bench , get some valuable data . Completion of the detection system provides a powerful tool to ensure the quality of their products for the domestic manufacturers of filter certain guiding significance for the future of the design and manufacture of automatic detection system filter .
