Detailed Description
1. Main specification and usage scope TLS-20000 digital displayed spring tension and compression testing machine is made according to the stated technical requirement of JB/T7796-1995《Technical qualification of spring tension and compression testing machines》, which is mainly used for testing the intension of all kinds of screw spring and elastic components. For other words, the testing machine is used to test the load of the spring in a certain deformation, or to test the deformation of the spring in a certain load. 2. Main specifications technical parameters and indexes: Serial Number Item Specifications, parameters and indexes 1 Max. test load 20KN 2 Valid measurement scope of test load 2~20KN 3 Min. resolution of test load 0.01KN 4 Min. graduation of auxiliary scale 0.05mm 5 Max. distance of two pothooks of tension test ≥1000mm 6 Max. distance of two compression plates of compression test ≥1000mm 7 Max. displacement of tension and compression test ≥1000mm 8 Plate diameter Ф200mm 9 Relative error of indicating value of test load ≤±1% 10 Relative error of indicating repeatability of test load ≤1% 11 Zero-resetting error ≤±0.1% 12 Power supply (three phrases, four lines) 380V±10% 3. Working condition: The tester can work normally under the following conditions. 3.1 Room temperature is within the range of 10~35ºC; 3.2 Relative humidity≤80%; 3.3 Precise Installation on firm foundation 3.4 Working under the condition without vibration, without corrosive medium, and without interference of strong electrocity. 3.5The fluctuating scope of the power supply voltage doesn’t exceed ±10% of the rated voltage.
