DWTT drop hammer tearing tester is applicable to various ferritic steel, in particular to a drop hammer tearing impact test of various pipeline steel. The DWTT drop hammer tearing tester meets GB/T8363-2007 and an ASTM E436 testing method. A mainframe of the drop hammer tearing tester adopts a four-support type stable structure, has good rigidity and double slide guide rails which is provided with an automatic sample transportation mechanism, a positioning mechanism, a tilt prevention mechanism, a safety mechanism, a hydraulic buffer device, a test sample reclaiming device and a safety prevention device. The drop hammer tearing tester can adjust the preset impact energy through two modes of controlling the hoisting height of a drop hammer and increasing or reducing balance weight. According to different operation control modes and measuring display modes, the drop hammer tearing tester comprises two types: a digital display drop hammer tearing tester and an instrument drop hammer tearing tester.
The digital display drop hammer tearing tester is characterized by singlechip microcomputer control, touch screen and key-press operation, hoisting height display and control, and presetting and display of the maximal impact energy.
By adopting a microcomputer control mode, the instrument drop hammer tearing tester can acquire and analyze test data.
a. Measurement and Control of the Hoisting Height of the drop hammer: the testing precision is ±1 mm, and the controlling precision is ±5 mm;
b. Measurement of the Impact Speed: measure the maximal impact speed before the impact of the drop hammer.
c. Load Measurement: measure load born in the drop hammer impact process and draw load-time waveform
d. Data Acquisition and Storage: imported data acquisition card with high performance and sampling rate ensures enough sampling points in the very short impact process and ensures the truth of an energy change curve.
e. Software Analysis: With strong software analysis functions, the digital display drop hammer tearing tester provides various data processing results of preset energy, impact energy, absorbed energy, impact speed, impact time, maximal load, energy in maximal load, time in maximal load, deformation in maximal load, load-time waveform and energy-time waveform, and can automatically generate a detection report including various testing results and the size, trademark, number, temperature, and environmental temperature and humidity of the test sample.
