The compression device of the 2kN ~ 1000kN spring tension tester is tested: The maximum capacity of the spring tester is not more than 2kN applied to the maximum test force of 10％, and the Renyifangxiang is measured between the upper and lower pressure plates with a stopper; The capacity of the spring tester is greater than 2 kN so that the upper and lower pressure plates leave a certain distance. The difference between the maximum and minimum values of the scale is read by measuring the circumference of the upper and lower pressure plates along the circumference of the upper and lower pressure plates. JB/T7796-2017 is suitable for spring tension and pressure test machines with a maximum capacity of 1000 kN and below. |
