弹簧拉压试验机主要供各种螺旋弹簧做拉伸或压缩试验，即在一定负荷下测量弹簧的变形量。本文将弹簧拉压试验机常见的故障及排除方法列出仅供参考。 故障现象之一：指针对零不稳或做试验后指针不能回零。 产生原因：１、拉杆与立柱上端四个滚动轴承间的间隙太小。２、指针与刻
Spring tension and compression testing machine for a variety of helical springs for tensile or compression test, that is measured under certain load spring deformation. This article will spring tension and compression testing machine common troubleshooting and troubleshooting are listed for reference purposes only. One of the symptoms of failure: Pointer zero instability or after the test pointer can not return to zero. Reason: 1, the upper rod and column four rolling bearing clearance is too small. 2, pointer and engraved
