Some precautions when using the testing machine
Some precautions when using the testing machine
Testing machine, broadly speaking, is an instrument that verifies the quality or performance of a product or material according to the design requirements before it is put into use. From the definition, it can be seen that any instrument that verifies the quality or performance can be It is called a testing machine. The products of the testing machine are constantly innovating, improving, and perfecting, and can adapt to the various properties of the testing materials. In order to let everyone know the testing machine better, let us take a look at some attention when using the testing machine. Matters. 1. The fixture of the testing machine must be coated with anti-rust oil. 2. Always check whether the screws of the jaws are loose, and tighten the loose screws in time. 3. Always check whether the connecting wire behind the controller is in good contact, but pay attention , You must turn off the power of the controller to plug in the interface of the cable. The interface is corresponding, otherwise it will cause damage to the testing machine. 4. Some testing machines will affect their service life when they are energized for a long time, so it is long Please turn off the controller and computer if you don't use the machine for time. 5. A person must be responsible for maintaining the scale wing test machine. In order to prolong the service life of the test machine and the accuracy of the test data, maintenance during the use of the test machine becomes particularly important.
Hydraulic universal testing machines have very high accuracy requirements.
The hydraulic system is the power drive mechanism of the tensile testing machine.
The specific application of the electronic universal testing machine in the automobile manufacturing process: The electronic universal testing machine needs to be used for automobile parts.
Wave soldering refers to the molten solder (lead-tin alloy), sprayed by electric pump or electromagnetic pump into the solder wave required by the design, can also be formed by injecting nitrogen into the solder pool, so that it is pre-loaded The printed board of the component realizes the soft soldering of the mechanical and electrical connection between the solder end or the pin of the component and the pad of the printed board through the solder wave.
The frequency converter is a power control equipment that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply.
Electronic universal testing machine is a necessary equipment to control the quality of products.
The calibration operation of the electronic universal testing machine is still relatively unfamiliar to friends who use it for the first time.
Selective wave soldering defects and their prevention.
The tensile force is not an accurate value after being measured by the testing machine, and subsequent calculations are required to get the desired value.
In order to prevent accidents, safety protection devices are installed in the design of the testing machine.
