In order to control costs, many enterprises pay too much attention to price when purchasing tunnel bolt, which leads to various problems in later use. In fact, the important thing to buy tunnel bolt is to look at its quality and the after-sales service and reputation of tunnel bolt manufacturers.

What should I pay attention to when selecting tunnel bolt?

tunnel bolt is based on the moment the impacted sample is hit by a hammer, and the signal is generated by a high-speed force sensor. After the signal is amplified by the high-speed amplifier, it is quickly converted from A/D to digital signal and sent to the computer for data processing. At the same time, the angular displacement signal is sent to the computer for data processing with high precision. The instrument is based on an impact structure that meets national standards and is equipped with a high-speed angular displacement monitoring system, a force detection sensor and an amplifier. After high-speed sampling and data processing by computer, N-T and J-T can be displayed.

tunnel bolt has the following functions: The main engine of the testing machine is a single pillar structure, the cantilever pendulous mode, and the pendulum body is U-shaped; The impact knife is fixed with screws, easy to replace; Sample simple beam support; The main engine is equipped with safety pins and safety nets; The test machine is semi-automatic control, swing, swing, impact, swing are electronic control, can use the residual energy after the sample is broken automatically swing, to prepare for the next test. Especially suitable for continuous impact test laboratories and do a large number of impact tests of metallurgy, machinery manufacturing departments.
