Residual depression test machine > The working principle of: Residual depression refers to the ability to depression caused by heavy objects such as plastic floor anti -furniture in static loads. 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 are revised and upgraded by the old manual residual depression test machine A set of > automatic test system , one -click test automatically produced the result, improved the previous manual placement of loads, and when the load was put on the heavy shock, it exceeded the process of not being accurate, manual timing heavy load, and sometimes forgotten to forget Time exceeds the test, and the test results need to be re -measured. The full -automatic residual depression test machine has the advantages of provincial , 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, you must not touch the test sample or the force measurement device, because in the test, because in the hand, because it is in the test, because it is in 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: > Floor
Residual depression test machine Also known as floor residual indentation test machine, the test machine is a method that determines the residual depression of the elastic floor. After load, it is produced on elastic or thin -piece floor coating. 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 suffering from static, and before the measurement is measuredThickness and thickness after recovery.> Main technical parameters
