Attention to test steps of electronic universal testing machine

Source: Tensile testing machine April 26, 2018 Keywords: Universal testing machine matters needing attention    

Electronic universal testing machine is used by many enterprises. What should be paid attention to in the use of electronic universal testing machine? We summarize as follows

1. Before using the electronic universal testing machine, turn on the main power supply first, and then confirm whether the power supply is normal without big fluctuation.

2. Sample selection: firstly, select the appropriate number of samples according to experience, and then determine the measurement range of electronic universal testing machine. Through adjusting the buffer valve on the swing rod, pay attention to the adjustment tightness of the buffer valve. If the first test is conducted, the force of the buffer valve must be increased, and the alignment mark should be paid attention to.

3. Installation test of electronic universal testing machine: when installing, we must pay attention to the selection of size, and fix the place to be stressed according to the sample, and do not use gaps or looseness.

4. Pressurization start-up process: first start the electric universal test oil pump motor, then open the oil delivery valve, so that the test bench rises 10 mm, then close the oil delivery valve. If the position of the test bench has been in the expected position before this, it is not necessary to open the oil delivery valve to raise the test bench.
