China Shipbuilding Industry CorporationGroup Company 725 Research Institute:15000JLarge pendulum oscilloscope impact testing machine
China Shipbuilding Industry Corporation (CSIC),CSIC was established on July 1, 1999,It is a super-large state-owned enterprise formed by the reorganization of some enterprises and institutions of the former China State Shipbuilding Industry Corporation,It is mainly engaged in the research and development and production of naval equipment, civil ships and supporting, non-ship equipment,It is the only one of the world's top 500 enterprises in China's shipping industry。Purchased the 15000J large pendulum oscilloscope impact testing machine developed by Wanyi。
This equipment is another large-energy pendulum impact testing machine developed by our company. This machine is mainly used for the drop hammer tear test of pipeline steel and medium-thickness steel plate ferritic steel, that is, DWTT test;And the dynamic tearing test of medium-thickness ferritic steel, that is, DT test。During the test, the hammer of a certain mass is lifted to a certain height, and then released by static, the hammer falls freely and impacts the sample, causing the sample to tear。By observing the characteristics of the fracture surface of the sample, the impact resistance of the material is studied and judged。
The testing machine has the function of instrument impact (oscillographic impact), accurately measure the force-displacement curve of the specimen when it is broken, and obtain the characteristic values of the impact force, which provides quantitative basis and results for the study of the impact resistance of the material。At the same time, the testing machine realizes the process of automatic lifting, sample delivery, impact, fracture sample collection, and then grasping the hammer。
The design engineer of this equipment in our company has more than 10 years of similar equipment design experience,In-depth understanding of similar products at home and abroad,The technology used is combined with the corresponding national standards,The 15000J large pendulum oscilloscope impact testing machine is designed,At the same time, our company has many years of similar equipment production experience and mature manufacturing technology,The 15000J large pendulum oscilloscope impact testing machine was produced,It has excellent quality and reliability, good operability, convenient maintainability and safety。
