Notes on precautions before operation of friction and wear tester

Author:admin      Created:2017-08-18      Views:1083

No matter what kind of equipment is used before the use of a series of testing, friction and wear testing machine is no exception, the purpose of this is to test orderly and efficient, and of course, the test equipment is a kind of intangible protection. Today we are going to introduce the preparations that must be made in several experiments.

1. Whether the test conditions meet the working conditions of the test machine; the so-called test conditions include the basis of environmental temperature, humidity, magnetic field, voltage and stability, because different materials will change the molecular structure within the material with the change of the working conditions, which leads to the gap of the test results, and the result of the test results will be made. There will be a deviation or a null and void.

2, electrical wiring is correct, there is no leakage phenomenon; different connection lines for different connections, which line is connected to the host and computer, which line is connected to the mainframe and power, and so on, must ensure its correctness. Of course, the manufacturer uses different joints to solve the different connection lines of this problem. The user is very convenient to distinguish it. This will not be a problem, but once the protective sleeve of the connection line is damaged, it will increase a certain risk. Once the leakage result is unbearable.

3. Whether the motor is right or not;

4. Whether the height of the lubricating oil in the spindle box is correct;

5, switch on the power supply, so that all components are in preheating state. Especially in winter, this is done in order to protect all parts of the test equipment. For example, in winter, when the car starts, the car should be pre heated so as to better protect the engine. And this kind of processing method of the test machine also has the similar automobile, all is one kind of protection to the equipment.

The above preparation is the characteristic of the testing machine, except for the d), and it is also applicable to the tension test machine, the electronic universal testing machine and the hydraulic universal testing machine.

A simple introduction to the test of friction and wear testing machine before the preparation, I believe that the use of everyone will have a little help, in addition, about the friction and wear testing machine can call the hotline 0531-85860713/85860723.
