Product Details

1 Equipment Name: Microcomputer-controlled horizontal electronic tensile testing machine (horizontal coal-specific)

2 Equipment Model: WDL-300C

3 Equipment Use:

WDL-300C computer-controlled horizontal electronic tensile testing machine (horizontal coal mine only) is mainly used for coal connection chain tensile test and connection bolt pull shear test for coal mine field test.

The machine adopts horizontal lightweight design, six-column frame structure can be installed in the light bus (Iveco) or light truck (light truck) on the use of, arrived at the scene after only an external 220V power supply can be. The system adopts AC servo motor to drive the ball screw by the decelerating mechanism. The tensile test force is applied by the crossbeam, the servo motor of the closed-loop control computer is controlled automatically, the load sensor is measured and the force and test curve are displayed on the computer screen in real time. The requirements of automatic test data. The control unit uses the computer and the servo control system composition, has the stress, the strain, the displacement control way and mutually smooth switching. The test data can be accessed at will, the data and curve can be reanalyzed, the partial magnification and the data re-edited, the sample, the environment and the testing condition can be programmed, the mechanical performance indexes of the material can be obtained automatically, Of the test reports and curves. The machine is made up of rack, fixed base, movable beam, sensor, servo motor and control system and software. The servo motor is used as the power element in Taiwan to apply the tensile load of 300kN. The computer is used to control and test the whole process. Simple and convenient; the main components of the machine force transmission sensor US brand (high precision, good stability), ball screw with Taiwan brands, other accessories using domestic brand-name products, long-term stable and reliable.

4 Features:

4.1 computer control, software interface menu prompt, easy to operate;

4.2 user self-editing report function. Data can be easily imported Excel form, user-friendly post-processing;

4.3 The test process and measurement, display, analysis, etc. completed by the computer;

4.4 Automatic shift: according to the size of the load automatically switch to the appropriate range to ensure the accuracy of measurement data;

4.5 automatic transmission: beam speed during the test can be pre-set program automatically changes can also be manually switched;

4.6 curve selection: select force - time / force - displacement / force - deformation curve display and print;

4.7 A variety of protection measures. Such as: a variety of electrical power protection, the software part of the overload, super-displacement protection, mechanical safety limit protection, etc.;

4.8 The host adopts the frame horizontal structure, the whole rigidity is high; The power uses the servo motor to drive the ball screw to rotate to drive the beam to move, the loading is steady, the control precision is high, the noise is low, the testing machine's long life, the long-term stability is good;

4.9 arc tooth synchronous deceleration system, with high efficiency, long life, low noise, maintenance-free advantages.
