Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic testing, and in particular to a hydraulic testing protection device. Background Technology
[0002] Accumulators play an important auxiliary role in mechanical hydraulic systems. Their simplest working principle is to store the pressurized oil output from the hydraulic system in the accumulator. When the hydraulic system stops working, the accumulator uses the previously stored pressurized oil to start the hydraulic system again. This reduces the time of mechanical damage and plays a key auxiliary role in ensuring the normal operation of the hydraulic system.
[0003] Before the accumulator leaves the factory, it needs to undergo various performance tests. One of the key tests is the hydraulic oil pressure test, which checks whether the pressure value of the hydraulic oil meets the standard pressure value.
[0004] However, in most existing hydraulic detection and protection devices, the accumulators are limited and protected during the detection process by a flip-adjustable protective structure to prevent them from tipping over. In actual use, since the detection device can detect and process multiple accumulators at the same time, this flip-adjustable protective device is difficult to accurately protect multiple accumulators simultaneously during the flip-adjustment process, making it inconvenient to use. Furthermore, this type of protective device only provides a simple covering protection effect, and the protection effect needs to be improved.
[0005] Therefore, this utility model proposes a hydraulic detection and protection device. Utility Model Content
