The microcomputer-controlled electro-hydraulic servo universal testing machine needs to be properly installed according to the manufacturer's instructions before it is officially used. The safety of the universal testing machine is making the foundation. After the foundation is finished, the equipment is in place, and then the level is adjusted, and then poured, to ensure that the base of the universal testing machine is well combined with the cement foundation, to prevent the test machine from being not level due to vibration during use.
After the universal testing machine (www.lgtester.com) arrives at the laboratory, the packaging is removed, the main host and the oil source of the testing machine are respectively transported to the foundation of the concrete, according to the external drawing provided by the testing machine manufacturer and the foundation drawing of the testing machine, and the tubing size determines the distance and direction between the main unit and the oil source. Then use a thin plate to fit between the bottom of the main unit and the foundation. Then use a 0.05/1000 square level to perform the alignment, place the square level on the outer surface of the cylinder, and align the verticality on the two sides perpendicular to each other. Its verticality should be no more than 0.2/1000. Or put the bar level on the workbench and align its level, the level should be no more than 0.2/1000.
After the universal testing machine is aligned, the grounding nut is poured with cement, and fasten the pad underneath the base. The cement is used to fill all the gaps under the machine base to maintain the good combination of the base of the universal testing machine and the cement foundation, so as to prevent the testing machine from being not level due to vibration during use. After pouring the anchor bolts, before the cement is not dried, it is not allowed to fasten the test machine with the anchor bolts and start the main machine (the cement drying time is generally not less than 10~15 days). After the cement is dried, fix the test machine on the foundation with anchor bolts. Review the installation accuracy of the test machine to see if it matches the accuracy of the alignment. If not, re-align.
