Steel wheel wear testing machine

The cycloidal pinwheel reducer has the advantages of large reduction ratio, compact structure, smooth transmission and adjustable abrasive flow rate, which can effectively save the amount of abrasive. The testing machine through the gear drive deceleration to steel wheel speed 75r/min, gear drive compared with the belt drive deceleration, smooth, no skid phenomenon, steel wheel rotation by the time relay control, the motor to the predetermined time is also transferred to the test requirements of the speed

The motor stops automatically. The testing machine has the characteristics of reasonable design, simple structure, beautiful appearance, easy operation, smooth rotation, automatic shutdown to meet the test requirements, etc., which is mainly suitable for wear resistance test of cement bricks.

Application

The steel wheel wear testing machine is widely used in materials science and engineering to evaluate the wear characteristics of various materials. It simulates the wear process of materials in actual use by applying friction from a steel wheel under fixed testing conditions. This method effectively simulates the actual performance of materials under friction and wear conditions.

Test Procedures

1- The sample to be tested is fixed with the help of fixing apparatus.

In order start using to device, the sample is fixed by placing it in its place via the handle on the device.

2- Before adding abrasive grit, it should noted that the valve under the sand chamber is in the closed position.

3- Abrasive sand is filled into the hopper.

4- To adjust the revolution speed, firstly press to "Set" button and after "PRST" button.

5- Sample is should by push lever up place it in contact with the disc.

6- For Start to test, should press to "Start" button.

7- When the disc begin rotate, slowly open grit valve.
