Hydraulic machine shaking tricks Time: 2015-04-08 Source: http://
Due to its own tonnage, the hydraulic press will not slosh during use, so when it encounters shaking, stop working immediately, check the reason, and remember not to be careless.
Phenomenon 1: In the work engineering, the phenomenon of sudden loss of load is caused by the sudden decrease of the fracture resistance of the material during the blanking, punching and trimming of the hydraulic machine, which will cause the impact of the moving beam, the frame and the pipeline. vibration. 
Phenomenon 2. After the pressurization, the hydraulic machine is suddenly pressurized. After the hydraulic pressure of the working cylinder is elastically compressed, a certain amount of energy is stored. During the returning process, the unloading pressure is faster, and this part of the energy is suddenly released, which will also cause impact vibration.
Phenomenon 3: When the sliding beam suddenly stops moving and the pipe valve suddenly opens or closes, the sliding beam movement suddenly stops, and the impact vibration will be caused by the inertia of the frame. When the pipeline valve is suddenly closed, the inertia of the flowing liquid in the pipeline will also cause impact vibration. When the pipeline valve is suddenly opened, the speed will change abruptly due to the sudden flow of the liquid, which will also cause shock vibration.

In summary, the operation and use of hydraulic press must develop good habits, good at maintenance, and play the maximum effect of hydraulic equipment.
