摘要：

为准确有效检测氧弹量热仪中氧弹的安全性能，解决目前人工千分尺测不准的问题，研制一种量热仪氧弹自动检测装置。该装置经液体加液，用电涡流测距传感器测氧弹形变，测量范围0~6 mm，分辨率1 μm，准确度0.2%，压力范围0~25 MPa，准确度等级0.05级，满足DL/T 661-1999《热量计氧弹安全性能技术要求及测试方法》对氧弹安全性能检测要求。装置操作自动化程度高、准确、安全，可作为计量部门对量热仪氧弹安全性能检测标准装置。

Abstract: In order to detect the safety performance of oxygen bomb in oxygen bomb calorimeter accurately and effectively, and solve the problem of inaccuracy of manual micrometer, a calorimeter automatic detection device for calorimeter is developed, which is charged with liquid. The device has a measuring range 0-6 mm, resolution 1 μm, accuracy 0.2%, pressure range 0-25 MPa, and accuracy level 0.05. The device meets the requirements of DL/T 661-1999 Technical requirements and test method for the safety of calorimeter bombs for safety performance testing of oxygen bomb and has high degree of automation, accuracy and safety which can be used as a standard device for safety performance testing of calorimeter oxygen bomb by metrology department.
