Description

TECHNICAL FIELD

[0001] The utility model belongs to pressure gauge technical field, specifically is a pressure gauge anti -shock detection machine. BACKGROUND

[0002] As a key measuring instrument in the industrial field, pressure gauges are widely used in oil, chemical, power and other scenarios to monitor system pressure in real time to ensure safe operation of equipment. However, under complex working conditions (such as mechanical vibration, pipe impact, etc.), pressure gauges often bear multi-directional alternating loads, and their anti-shock performance directly affects the measurement accuracy and service life. If the anti-shock ability is insufficient, it may cause the pointer to deviate, internal components to be damaged or even to fail, thereby causing safety hazards. Therefore, scientific and comprehensive anti-shock detection of pressure gauges is a necessary link to ensure their reliability.

[0003] The prior art has the following disadvantages: Most devices can only simulate single-direction vibration, such as horizontal or vertical direction. However, in actual working conditions, pressure gauges are often subjected to multi-directional composite vibration. This single-direction vibration simulation cannot comprehensively and truly reflect the stress conditions of pressure gauges in actual use environment, resulting in a large deviation between the test results and the real environment. Since multi-directional composite vibration cannot be simulated, the existing devices cannot accurately capture the coupling effect of vibration in different directions and its comprehensive influence on the performance of pressure gauges when testing the vibration response of pressure gauges. This makes the test results lack in accuracy and cannot provide sufficient basis for the design optimization and reliability evaluation of pressure gauges. UTILITY MODEL CONTENTS
