气液增压泵讲解气密性检测仪检测四要素

气密性检测仪又叫密封测试仪或泄露性测试仪，主要适用于食品、制药、医疗器械、日化、汽车、电子元器件、文具等行业的包装袋、瓶、管、罐、盒等的密封试验。Gastightness detector called seal tester or leak testing instrument, mainly is suitable for the food, pharmaceutical, medical, chemical, automotive, electronics, stationery and other industries packaging bags, bottles, cans, boxes, pipe sealing test.在气密性检测仪检测零件的整个测量过程中，包括以下四方面的内容：In the whole measuring process gastightness detector measurement of parts, including the following four aspects:1、检测方法。指检测过程所采用的测量器具、检测原理以及检测条件的综合1, detection method. The comprehensive index of the detection process of measuring instruments, measuring principle and the detection conditions2、检测对象。主要指的是被测零件的有关几何要素2, object detection. Mainly refers to the geometric elements of the workpiece to be measured3、检测精度。指检测结果与理想值的一致程度。任何检验测量都免不了会产生误差，因此，误差和精度是两个相互对应的概念3, the detection precision. The test results and the ideal value of the degree of agreement. Any test measurements are inevitably leads to errors, therefore, error and precision are two relative concepts4、计量单位。指国家的法定单位，长度单位是米(m)，其他常用单位有毫米(mm)和微米(um)4, unit of measurement. The legal unit state, unit of length is the meter (m), other common unit of a millimeter (mm) and micro (UM)气液增压泵http://www.xinmingte.com/
