Hidden dangers when installing hydraulic universal testing machine

This article mainly talks aboutHidden dangers when installing hydraulic universal testing machine.

it is knownThe hydraulic universal testing machine must be installed and debugged before use, so the selection of installation method and location is also crucial. The selection of installation location is based on the criterion of convenience of use. There are no special requirements, just make the foundation. It is to be exaggerated here that if the hydraulic universal testing machine is inappropriate, it will affect the accuracy of the experimental machine's value display, and even directly affect the service life of the hydraulic universal testing machine. For example, the main difference is the advantages and disadvantages of the degree of the dynamometer device, which has a more significant impact on the accuracy of the hydraulic universal test machine.

Here we focus on the impact of inaccurate hydraulic universal testing machine equipment on the accuracy of the display value:

1. If the oil cylinder and piston of the host device are not vertical, it will cause a deviation in the indication value. If the main unit is not in the right way, the guide wheel on the column will be inclined to one side, because the spherical support in the piston will be inclined to one side, which will cause the difference between the upper and lower chucks and the upper and lower pressing plates, and the squeezing of the guide wheel will cause great friction, which will occasionally squeeze the guide wheel, and the test stand will be guided, and the sample will not be disconnected in the central position. This question affects application and displays

2. The deviation of the display value caused by the incorrect dynamometer device. Please be sure to use the dynamometer device to the right. If it is tilted to the right, the angle between the vertical line of the tooth rod and the push rod will increase, which will cause too little oil pressure and affect the accuracy of the experimental machine. If the dynamometer device is to the left, the result will be reversed.
