1. The whole machine can't be turned on and the power cord or fuse holder is not in good contact. | Check the circuit, find out the reason and solve it. Phase-sensitive zero adjustment failure phase-sensitive rectifier wiring or part of the rectifier diode performance does not | check the ...

This standard stipulates the test method of mechanical properties of ordinary concrete. This standard mainly carries out compressive strength test, axial compressive strength test, static compressive modulus test, splitting tensile strength test and flexural strength test. This test can be com...

The purpose of tearing experiment of electronic universal testing machine is to find the tearing strength value. The rubber products with or without cuts are stretched continuously at the prescribed speed until the rubber pattern is torn, so that the tearing strength value can be obtained. The te...

The test machine uses hydraulic loading and computer screen display to show the test results. It is easy to operate and the test readings are accurate and reliable. It is mainly used for the tensile performance test of concrete prestressing strands. Additional accessories can be used for tension,...

Summary It is most commonly used in bridges, dams, roads and buildings. Common material properties tests include tensile test, bending test and hardness test. The results of these tests are used to ensure that these products meet the material specifications and classification requirements. Co...

Before using any test machine, we should fully understand the performance of the product and fixture, so as to better realize man-machine running-in during the operation process. In order to improve production efficiency. Next, we will introduce to you the performance characteristics of the elect...

Pressure testing machine should be installed in clean, dry, vibration-free, non-corrosive gas impact room. The installation foundation should be firm and reliable, and the foot bolts should be on the base. After the machine is installed horizontally, clean and kerosene-soaked cotton yarn is appl...

What you need to pay attention to when installing the universal testing machine: First of all, the universal testing machine needs to be installed in a clean, dry, no vibration, and indoor temperature in the room of 20 to 10 degrees, while also doing beam bending test, can also use the extensome...

As a high-precision testing instrument, the universal testing machine has a relatively high price and a long service life. It must check the internal configuration of the universal testing machine when purchasing. The internal configuration directly affects the service life of the universal testi...

In recent years, with the improvement of engineering quality requirements and the replacement of engineering materials, the laboratory will encounter more and more large-scale and high-strength steel bar inspection tasks. The maximum force of these steel bars will exceed 900kN or even 1000kN, whi...

10000kN microcomputer controlled electro-hydraulic servo compression shear testing machine The microcomputer-controlled electro-hydraulic servo compression shear tester is mainly used for testing the axial radial compression, shear and corner of the support under various complicated conditions...
