NJ-S200

Digital display anchor torsion testing machine

1. Product Introduction:

The NJ-S series digital display torsion testing machine is composed of a loading system, a transmission system, a digital data acquisition and processing system, and a liquid crystal controller display system. It is suitable for static torsion mechanics performance testing of metal materials, non-metallic materials, and various components such as bolts and nuts, torque wrenches, hardware tools, transmission shafts, bimetallic material parts, and fasteners.

The machine adopts a horizontal structure, featuring a liquid crystal display for real-time display of torque and torsion angle, a ZCTest II digital data acquisition and control system, and a fully digital AC servo system. It employs a planetary cycloid pin wheel reducer for transmission, which ensures uniform and stable loading, no impact phenomenon, and accurate data acquisition and control.

The NJ-S100 digital display anchor torsion testing machine is a specialized equipment customized according to user requirements, specifically designed for resin anchor rods and glass fiber reinforced plastic rods, used for the installation and operation of anchor force and pull-out force test samples, as well as torsion performance testing.

II. Test and Measurement Functions:

The ZCTest II digital data acquisition and control system achieves various controls of torque and torsion angle, with customizable display screens and operation panels; it allows for the setting of test speeds and various control parameters; it provides real-time display of torque and torsion angle; it displays various relevant parameters during the test process in real time; and it enables system diagnosis and displays diagnostic results.

The entire machine utilizes a fully digital AC servo control system and a ZCTest digital data acquisition and processing system, with a photoelectric encoder to collect the torsion angle of the test sample. This torsion testing machine features a simple structure, easy operation, and low cost, and is mainly suitable for use in mechanical laboratories of scientific research institutions, various colleges and universities, and industrial and mining enterprises for determining the torsion performance, anchoring force, and pull-out force of materials, as well as for sample installation and operation.
