Troubleshooting of Displacement System of Tensile Tester

The displacement testing technology of tensile testing machine is widely used in industrial production such as tensile testing equipment. Displacement detection is the basis of mechanical quantity detection. Converting mechanical quantity into displacement 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 tensile testing machines and universal material testing machines, the traditional static electro-hydraulic measurement and control methods cannot meet the requirements of current hydraulic systems in terms of performance, operation, online monitoring and fault diagnosis, so the development of online monitoring and analysis systems is particularly important.

If you find that the displacement system fails, you must deal with it in time. If you can solve it yourself, you can solve it yourself. If you can't deal with it, you can call Shanghai Jianhu Instrument Equipment Co., Ltd. for assistance. Our company has after-sales outlets all over the country. Among such problems handled by Shanghai Jianhu, there are mainly three main reasons.

 

1. First check the displacement sensor of the tensile machine, tensile testing machine, and universal material testing machine. Since the displacement system of the tensile machine adopts a three-closed-loop control method, 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 feedback data of the sensor is a straight line that changes linearly, and it is determined whether the sensor is normal.

 

2. Next check the amplifier unit. If there is no problem with the displacement sensor, you should focus on checking the amplifier unit of the tensile machine. The output signal of the normal amplifier unit should change linearly.

 

3. If the fault is not caused by the above reasons, you should check whether the computer software is set correctly; or re-calibrate and correct the displacement system.
