液压式万能材料试验机(以下简称试验机),是机械,冶金及建筑等工业部门试验室,测试材料机械性能不可缺少的基本设备之一,是为科研,设计及产品检验提供可靠的技术数据。如果,试验机在失准状态下工作,测得的数据不准,必然导致对材料性能的错误判断,因此,要求试验机的示值精度(或误差)必须控制在所规定的允许误差±1％以内。若示值精度超差即应及时检定调修。下面将我们在调修试验机过程中一些粗浅体会整理如下,供有关同志参考,不妥之处予以批评指正。
Hydraulic universal material testing machine (hereinafter abbreviated as testing machine) is an indispensable basic equipment for the mechanical properties of testing materials, such as machinery, metallurgy and construction. It is a reliable technical data for scientific research, design and product inspection. . If the tester is working in the misaligned state and the measured data is inaccurate, it will inevitably lead to erroneous judgment of the material properties. Therefore, the required accuracy (or error) of the tester must be controlled within the specified allowable error ±1. Within %. If the accuracy of the indication value is too bad, it shall be verified and repaired in time. Here are some of the superficial experiences we have learned during the process of repairing the testing machine. They are for the reference of the relevant comrades, and criticisms are given for any inaccuracies.
