Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of impact test, in particular to an impact test device for precision components of shale gas power generation equipment. BACKGROUND

[0002] The metal pendulum impact testing machine is a classical mechanical property testing equipment for determining the impact toughness of metal materials; The shale gas power generation equipment is a comprehensive system for converting unconventional natural gas, shale gas, into electric power. The core mission of the shale gas power generation equipment is to efficiently and cleanly convert shale gas into reliable electric power. The core part of the shale gas power generation equipment, especially the power generation area, is in an extremely high temperature environment for a long time in the working state. At a high temperature (such as the working temperature of the shale gas equipment), the material usually has good toughness and will undergo a large plastic deformation before breaking when impacted, and the absorbed energy is high. When detecting the material of the shale gas power generation equipment by the metal pendulum impact testing machine, the influence of temperature on the material needs to be considered, otherwise the detection result cannot substantially reflect the material requirements in the use environment. In the existing material heating impact test, the material is heated by a heating device and then transferred to the test area. In this process, the temperature of the tested material is affected by the environment and the transfer time, which seriously restricts the accuracy of the detection result, resulting in inaccurate detection result. Furthermore, the rotational friction of the bearing is a factor that restricts the accuracy of the detection result of the existing metal pendulum impact testing machine without considering air resistance. In the detection of the material of the shale gas power generation equipment, the material needs to be tested in a certain temperature range, so different temperatures are often required for multiple tests. This makes it necessary to perform an idle swing test before each batch of tests to determine the idle swing loss. However, the traditional idle swing test interrupts the formal impact test process, and the waiting and checking time further aggravates the temperature fluctuation of the subsequent test sample in the transfer process, forming an inherent contradiction between "temperature accuracy" and "checking efficiency", which seriously affects the accuracy of the detection result and the overall detection efficiency. Based on this, the present application proposes an impact test device for precision components of shale gas power generation equipment. SUMMARY
