The tensile testing machine, also known as the electronic tensile testing machine, is used to test the tensile strength of materials, which is well known to everyone. However, after using the tensile testing machine for a period of time, in order to ensure the accuracy of the test, accuracy needs to be adjusted. The manufacturer can debug it, and you can also master some maintenance methods to debug it yourself.
Firstly, we need to understand why tensile testing machines have inaccurate data. The reasons are also multifaceted. Electronic tensile testing requires the workpiece to work at the yield point, and in such an environment, it is easy for the workpiece to undergo plastic deformation or fracture, which can lead to inaccurate data in the electronic testing machine.
The main reasons for inaccuracy are: 1. The chuck may become loose, usually caused by sudden fracture. 2. The problem with the circuit is mainly caused by plastic deformation, as plastic deformation may cause some overload to the circuit, causing capacitor breakdown and affecting the test data.
The maintenance methods are divided into: test repair, minor repair, and major repair. Conduct testing and repair once a week, mainly for testing. The testing method is to test a previous workpiece, remove the error from the previous test, and then see how much the error is. Lock the loose parts and try to minimize the error during testing. Minor repair: Maintenance refers to the inspection and testing of various parts of the equipment, cleaning of foreign objects, and measuring in preparation for the next major overhaul. Major repair: It refers to the replacement or repair of parts with significant wear based on close observation and minor repair measurements.
Equipment must be carefully maintained and maintained. Only when the equipment is well maintained can it not affect its use at critical moments and save maintenance costs.
