The working principle of the residual depression test machine is : The residual depression value > refers to the ability of plastic floor anti -furniture and other heavy objects to cause depression in the static load. The test method is to use a standard cross -section spherical or cylindrical head. After adding the time specified by the constant load, the pressure is measured, that is, the depression. After restoring the prescribed time, deformation at this time is the residual depression.
The composition of the residual depression test machine is mainly divided into: racks, workbench, thickness measurement device, heavy -duty device, dating device, mobile lifting mechanism, controller.
The rack of the residual depression test machine is made of steel, so that under the action of large loads, the variable variables along the axis direction will not be greater than 0.05mm.
The same axis of the lift measurement thickness and the spindle axis should not be greater than φ0.3m.
Full -automatic floor residual depression test machine is AOTSI A Tengsus Company, which is revised by the old manual residual depression test machine Automatic testing system >, the one -click test automatically produced the result, and improved the previous manual placement of loads. Test results need to do issues such as measuring records. The full -automatic remnant depression test machine has the advantages of saving time, effort, labor, and accurate test results.
There are fewer places to pay attention to the residual depression test machine. What needs to be noticed is that in the test, it cannot be touched by the test sample or the force measurement device by hand. Because during the test, it must be corrected to zero the value at the beginning of the test, and at the beginning of the test, so that the accurate results can be obtained after the test.
Product introduction: >The depression test machine
Also known as the floor residual indentation test machine, the test machine is a method to determine the residual depression of the elastic floor. The floor coating is generated. The difference between the initial thickness and the thickness measured after the loading is removed, and the distance between the floor materials between the two parallel boards under the specified loading capacity. The sample is subject to static static, and the thickness before the force is measured and the thickness after the recovery period. > MainTechnical parameter
