Tensile testing machine of difference value reason have?

by:GESTER     2020-10-17
Tensile testing machine part load bearing before and after the installation is not level, will lead to two pendulum shaft rolling bearings under the effect of axial force and improve the rolling bearing sliding friction, the size of the sliding friction with the flatness to expand and ascend, and along with the ascension of the load. Tensile testing machine load part of the upper and lower bearing installation does not water the center line of the strain of the piston rod is not according to the iron blade axial force increased, improve the load piston rod and oil cylinder measuring forces of friction. Its characteristic is: for each baidu cloud resources in which relative deviation, relative deviation of a category in the same scale, too. Tensile testing machine load cylinder is too dirty, prompting the load piston rod in the move around when subjected to friction resistance, the load on the spring piece of swinging rod on the swinging rod, the leaf spring on the follower lever and whose hands the spindle rod rolling bearing friction plate is too tight, the rust is smudgy, pulleys, rollers and slippery iron tub etc with dirt. Strong vibration caused by a ruptured when time, prompting HouGaiBan anchor bolt looseness, caused by raw material tensile testing machine load of knife pad off, change the leverage ratio, make its cause negative deviation. ( Because the knife pad jumped down, is likely to go it would probably have to be to the right on the left, so sometimes can cause positive deviation) 。 Tensile test machine set for dirt or bf, plan adjustment difficult, prompting dynamometer axial force. On the spring piece of swinging rod load on the swinging rod, the leaf spring on the follower lever and whose hands the spindle rod rolling bearing friction plate is too tight, rust have smudgy, pulleys, rollers and slippery iron tub etc with dirt. Swinging rod spindle bearings have rust or dirt, or improper installation site, suffer from the harm of friction pendulum rod shaking. By tensile testing machine rocker shaft installed in the cabinet cannot be directly measured, can rely on the swinging rod and line vertical to the equivalent substitution method of main level. Will scale value not less than 0. 1/1000 of the frame level on the opposite end on swinging rod, by regulating motor shaft bottom pad to adjust to zero. 2/100mm。 To promote swinging rod make hard whose hands to 1/4 baidu cloud resources, then use top load piston rod in his hand, after drawing board smoothly, ease strain after the sinking of the piston rod piston rod needle top point to the load piston rod do nest, if the needle top not to strain of the piston rod of the piston rod, with adjusting pad is handled at the bottom of the base. The interpretation of the reasons of the poor in value is a tensile testing machine, hope can help you, if you want to learn more about information of tensile testing machine, welcome to the online consulting service or call the company service hotline ( Website top right corner) For consultation, we will wholeheartedly provide high quality service for you!
