HY type anti slip coefficient tester is mainly applicable to the inspection of anti slip coefficient of connection friction surface of 10.9 and 8.8 high-strength bolt connection pairs, high-strength large hexagon head bolt connection pairs, and the inspection of anti slip coefficient of connection friction surface of torsion shear high-strength bolt connection pairs (special wrench for torsion shear shall be specially ordered), testing and research.
High strength bolt connection pair: the general name of high strength bolt and its matching nut washer;
Anti slip coefficient: the ratio of the sum of the external force when the friction surface of the connector slides and the pretension of the high-strength bolt perpendicular to the friction surface in the high-strength bolt connection;
Liquid crystal microcomputer dynamometer has four physical channels and six groups of 24 logical channels.
Parameter backup, recovery function, peak holding function and automatic calibration function.
High strength large hexagon head bolt specifications: M16, M20, M22, M24, M27, M30.
Specifications of torsion shear high strength bolts: M16, M20, M22, M24.
In order to facilitate the user to connect with the computer, the llg358 interface is set (it needs to be ordered separately). The data can be transmitted to the computer for further processing and then the test report can be printed.
This equipment is simple to operate, and it is convenient to carry if it is sent to the Metrology Department for verification. The equipment upgrading and maintenance in the later stage are also extremely convenient. This equipment is a kind of high-strength bolt testing instrument with low investment and high return, which is currently popular in China's high-strength bolt manufacturing enterprises, engineering quality testing institutions, steel structure construction units, engineering supervision institutions, high-speed railways, bridge electric power, colleges and universities and other scientific research institutions.
