Matters needing attention and classification in the use of friction and wear testing machine
Friction and wear testing machine is also called friction testing machine and wear testing machine. The friction paper of the layer to be ground and the sample rubbed against each other at a specified speed under the action of the load friction body. The abrasion resistance of the ink layer (or coating) can be judged by measuring the decrease in density (or coating thickness) before and after rubbing. Next, the precautions and classifications in the operation of the friction and wear tester will be introduced.
1. Classification of friction and wear testing machine
1. According to the load range, it can be divided into: ultra nano friction and wear testing machine, nano friction and wear testing machine, micro friction and wear testing machine (10N), heavy load friction and wear testing machine (1000KN).
2.
According to the friction movement mode, it can be divided into: linear reciprocating friction and wear testing machine, high-speed linear reciprocating friction and wear testing machine (oscillating friction and wear testing machine), rotating friction and wear testing machine, high-speed rotating friction and wear testing machine, linear rotating friction and wear testing machine Combined testing machine.
3.
According to the friction pair, it can be divided into ball and disc friction and wear tester, pin and disc friction and wear tester, disc and disc friction and wear tester, ring block friction and wear tester, four-ball friction and wear tester, cylinder liner and piston ring friction and wear test Machine, high-frequency friction and wear testing machine, high temperature friction and wear testing machine, vacuum friction and wear testing machine.
2. Matters needing attention in the use of friction and wear testing machine
1. Adjust the parameters: check the displayed value of friction and test force, use with care, password protection
2. Adjust the zero point: adjust the hardware zero point (set before the factory, the user does not need to change)
3. Calibration friction: used to calibrate friction (it has been set before leaving the factory, the user does not need to change it)
4. The background parameters of the friction and wear testing machine: the background parameters are set by the manufacturer when they leave the factory. The user does not need to change them. After the change, there will be code confusion and inaccurate measurement data.
5. Do not operate the computer when a large amount of data is added and the system crashes
6.
During the test, the testing machine must not be too far away from the test equipment, nor can it directly perform operations other than the test. In some cases, when the unloading of the test force reaches the limit position, it will not stop actively and continue unloading, it must be stopped manually by emergency stop.
7. Do not connect the plug of the heating device to the socket when the friction and wear tester is performing the normal temperature test.
After understanding the precautions and classification of the friction and wear testing machine introduced by the editor, the operator must use the testing machine in accordance with the process specifications in the instructions. Otherwise, it is easy to cause machine failure and personal injury.

Next: Oil pump debugging and test procedures of hydraulic universal testing machine
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.
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.
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.
