液压千斤顶检定校准和不确定度评定探析

Verification and Calibration of Hydraulic Jack and Their Uncertainty Assessment Analysis

千斤顶为使用刚性顶举件当作工作装置,用底部托爪或者顶部托座于小行程里顶升重物的轻小起重设备。本文对液压千斤顶于校准及检定作业之中的大致调控过程进行解析和总结,并且对液压千斤顶校准及检定的调控重点和需要注意的方面及对其不确定度进行了评定探析和阐述。

The jack is one kind of light lifting equipment, and its working device is a rigid jacking assemblyjacking the weight in a small itinerary by the bottom claw or the top bracket. This article analyzes and summarizes roughly the regulation process of the hydraulic jack being verified and calibrated,and analyzes and elaborates the regulation emphases and matters needing attention of the hydraulic jack being verified and calibrated,and their uncertainty assessment done too.
