Treatment of Failure of Displacement System of Tensile Testing Machine

Treatment of Failure of Displacement System of Tensile Testing Machine
Displacement testing technology has a wide range of applications in industrial production such as tensile machine testing instruments. Displacement detection is the basis of mechanical quantity detection. Converting mechanical quantity into displacement quantity to detect is one of the important components of mechatronics technology. The detection of displacement not only provides important data for improving product quality and production safety, but also provides a basis for the detection of other parameters. In the tensile machine, tensile testing machine, universal material testing machine, the traditional static electro-hydraulic measurement and control method cannot meet the current hydraulic system's performance, operation, online monitoring and fault diagnosis requirements, so the development of online monitoring and analysis systems appears Especially important. If you find a fault in the displacement system, you must deal with it in time. If you can solve it by yourself, you can solve it by yourself. If you can't deal with it, you can call the after-sales phone 0531-61311328 to assist you. There are three main reasons for dealing with this kind of problems. The editor will list them for you, and you will deal with them accordingly: 1. First check the tensile machine, tensile testing machine, and displacement sensor of the universal material testing machine. Since the displacement system of the tensile machine adopts a three-closed-loop control method; therefore, the loop in the displacement system should be disconnected first to make it an open-loop system. Then measure the feedback value of the displacement sensor. After repeating several times, the measured sensor feedback data is a linearly changing straight line to determine whether the sensor is normal. 2. Then check the amplifier unit. If there is no problem with the displacement sensor, check the amplifier unit of the tension machine. The output signal of the normal amplifier unit should have a linear trend. 3. If the failure is not caused by the above reasons, you should check whether the computer software settings are correct; or re-calibrate and correct the displacement system.
