The vertical universal friction and wear testing machine is one of the most important models in the friction and wear testing machine. It is also the main product of our company. So, how should we start with the maintenance and maintenance of the friction and wear test machine? Let's get a simple idea of it. The vertical universal friction and wear testing machine mainly takes the form of sliding, rolling and compound friction, and the contact pressure should not be too large. Through different forms of friction pair, it is used to evaluate the long time wear resistance of lubricating oil and grease, and the friction and wear properties of metal materials.

The machine is generally equipped with four ball, pin, thrust ring and other three pairs of friction pairs, according to user needs can provide a variety of ball and disc friction pairs. The machine can measure the friction torque, calculate the friction coefficient, connect to the computer, record the temperature time curve and the friction coefficient time curve. It is usually equipped with high-precision measurement to realize the computer screen display, measurement and recording of friction spots, and can measure temperature control temperature and temperature regulation.

The main points of maintenance and maintenance of vertical universal wear testing machine are as follows:

1. All parts of the testing machine should be polished regularly. Wipe the surface without painting, then apply a small amount of oil to the cotton yarn and wipe it again to prevent rusting. During the rainy season, more attention should be paid to wipe, in order to prevent rust. Do not use machine cover to prevent dust intrusion, pay attention to sunscreen.

2, be careful not to let oil and dust enter the electrical control box.

When attachments and spare parts are not used, they should be placed in the corresponding accessory boxes neatly, and rusty parts should be coated with antirust oil.

3, connect the power supply, check the power is normal, if normal, the second step operation, if not normal, check power supply and strong power board air switch has been connected.

4, check whether the spindle rotation direction is correct. The spindle of the test machine is irreversible. From top to bottom, the spindle is clockwise rotation.

In addition, the testing machine should be checked every 1-2 years to ensure the correctness of the indicators.

Heng Xu's friction and wear testing machine is a precision instrument, so we must keep the maintenance and maintenance at regular time, so as to keep the precision and make the measurement more convenient.
