Tensile test machine, also called universal material testing machine and tensile machine, the electromechanical integration design, its main part, mechanical parts, hydraulic system, measuring system composed of measured force system is mainly composed of a force measuring sensing device, transmitter, microprocessor, load drive mechanism, the computer and a color inkjet printer.
Tensile Testing Machine
Rope net, textiles, metal rods, waterproof material, rubber, wire and cable, plastic, metal wire, plate tensile test available tensile testing machine, increasing attached with to do compression, bending test. With digital display test, continuously adjustable speed test, the samples were broken, automatic shutdown, peak hold function.
Installation, use and maintenance of tension test machine
Tensile testing machine should be installed in a clean, dry, no vibration and room temperature is 20 DEG C plus or minus 10 DEG C room, and pay attention to for bending test and using extensometer test and the equipment maintenance around the testing machine should be set aside enough spare area.
1. Installation
Tensile test machine, the main body and the dynamometer, device is installed on the basis of concrete, foundation size according to the shape and foundation drawing regulations, set aside anchor bolt and a lower jaw wire rod hole and other wire pipe installation etc.. On the basis of the flat surface should be flat, with the level of the foot to find the right, to be the foundation of dry, then put on the test machine.
Installation of a tensile testing machine and its preliminary accuracy
Based on the main body and the dynamometer were transported to the concrete, adjusted according to the shape and foundation drawing between subject and dynamometer distance and adjust the direction and available thin small pieces of iron are respectively inserted into the body and dynamometer bottom (with the base), 0.05 / 1000 precision horizontal square meter were found positive. The main initial alignment can be in two columns of the vertical and horizontal two different positions, with square level measurement, vertical degree shall be not greater than 0.3 / 1000, then the level of available square meter by two in the outer cylinder surface of the vertical and horizontal position, looking for the vertical degree.
2. Must pay attention to the operation
(1) If you are testing process, the pump suddenly stops working. At that time, the coupled with the load unload, the lower hydraulic check, and restart the pump test, should not be under high pressure starting pump or check the cause of the accident.
(2) If the tension test machine, electrical appliances, starting or stopping the button does not work, should immediately cut off the power, so that the test machine to stop running.
(3) Prohibit the operation of non operation of the machine operator.
