PHB-1 hammer type Brinell hardness tester

Overview

*The PHB-1 hammer type Brinell hardness tester adopts the principle of Brinell hardness test. The test force is applied by hammering, and the test force is precisely controlled by shear pins. After the test, a circular Brinell indentation is left on the sample. The diameter of the indentation is read out using a reading microscope, and a relatively accurate Brinell hardness can be obtained by checking the table.
*Test force F=1580kg, indenter spherical diameter D=7.26mm,=30, equivalent to 3000 kg force, under the test conditions of a 10mm ball.
*The PHB-1 hammer type Brinell hardness tester has a high testing force and does not require high surface smoothness of the sample.
*Due to precise control of the experimental force, the stability and reproducibility of the test results are good.
*The PHB-1 hammer type Brinell hardness tester has a testing error of 5-6%, and its accuracy is much higher than that of the old hammer type Brinell hardness tester.
*Each experiment only consumes one cheap shear pin, resulting in low testing costs.
*Testing is fast, simple, does not require sampling, and has appropriate accuracy.
*Suitable for hardness testing of large, inconvenient to move, and uncut castings and forgings.
