WAW-S Series Computerized PC Strand Tensile Testing Machine

(600ティッカー, 1000kN Capacity, 6 列, 0.5 クラス精度)

1. 紹介

This WAW-S series computer control servo hydraulic universal testing machine is designed for tensile strength test Rm, 非比例拡張の測定 Rp0.2, PCストランドの等 (プリストレス鋼ストランド).

It uses high precision load cell to measure testing force, high precision encoder to measure displacement and extensometer to measure deformation of PC strand.

It adopts professional hydraulic operated tensile grip, easy and quickly grip the sample. The successful testing ratio can reach to 100%, the sample is broken at the middle position. Not only it improves the successful testing ratio, it also saves time and testing cost. これは、PCストランドメーカーのための理想的な試験機です, 品質検査局, カレッジと大学, 等.

機械はISOに従って校正されています 75001 およびASTM E4. 試験規格, ISO6934に準拠しています, ISO6892認証取得, ETC国際試験規格.

2. 主要な技術的な変数

3. Professional tensile jaw:

Four pieces of tensile jaws are inserted into the tensile grip seat, then it adopts hydraulic operated the clamping and loosen of PC stand. The good quality tensile jaws are endurable, long life. It can tighten holding the sample without any loosen or slippage during the test. The well adjusted clamping force can not make the sample broken at the ends of clamping, it would break at the middle position of the smple.

4. Break Test
