Analysis of the error of the verticality of the force part of the hydraulic universal test machine

Today, the editor will introduce to you about the hydraulic universal testing machineThere are a total of the following six error analysis of the verticality of the afterburner part. I hope it will be helpful to everyone and is for reference only.

, When measuring the elastic modulus of low carbon steel, the reading error of the two dial gauges of the butterfly extensor is very large, and sometimes one of the gauges rotates in reverse. The main reason for this problem is that the verticality of the universal tester does not meet the requirements when the sample is stretched, causing eccentric stretching when the tester is stretched. Due to the poor pressure stabilization performance of the tester, the needle rotates in reverse, and some oil leakage in the hydraulic system occurs.
Second, if the verticality of the test machine cannot be guaranteed, the axial tensile of the sample is not guaranteed, and the obtained test data cannot guarantee the accuracy. For example: When we went to a place, we got the wrong car and we would definitely not be able to reach our destination.
Third, if there is a problem with the verticality of the test machine, it will cause friction between the single-sided roller of the movable workbench and the fixed column, and the accuracy of the load data cannot be guaranteed.
Fourth, if there is a problem with the verticality of the test machine, it will also cause one-side friction between the working cylinder piston and the cylinder wall, affecting the hydraulic system of the test machine, and thus affecting the service life of the entire machine.
Fifth, the verticality problem of the test machine will also cause friction to rise vertically by the chuck lifting worm under the test machine, causing increased mechanism wear.
Sixth, if there is a problem with the verticality of the test machine, it will also affect the automatic drawing device on the left, because the automatic drawing device on the left is driven by the rope and guide roller connected to the lifting workbench of the main body of the test machine, and is mainly related to the horizontal rack of the transmission load. Because the verticality of the test machine causes the load accuracy to be reduced, which will affect the automatic drawing device. Therefore, its tensile curve cannot test the true performance of the sample.

Hydraulic universal testing machine is divided into disc typeHydraulic universal testing machine, digitally explicit hydraulic universal testing machine, microcomputer screen display hydraulic universal testing machine, microcomputer control voltage servo hydraulic universal testing machine.
