How to Calculate the Pressure of Hydraulic Press Machine?

-

When customers inquiry about hydraulic press machine and tell us their product size and drawing, best hydraulic press solution will be provided for they. Do you know how to calculate the pressure of hydraulic press machine?

Cylinder ejection pressure (Kg) = cylinder area (square centimeters) × unit area pressure (Kg/square centimeters)
hydraulic press work
After hydraulic oil enters the system, it will encounter resistance from the pipeline along the way and overcome the frictional resistance of relatively moving parts. Due to frictional resistance, the hydraulic oil entering the system is continuously compressed, and the pressure continues to increase. Until the pressure of the hydraulic oil rises to a level that can overcome the above two bridge spring resistances, the gear pump still pumps a certain amount of oil into the system. The fluid is sent into the rodless cavity of the oil cylinder, so the piston moves upwards driven by the hydraulic oil, lifting the heavy object.
During the use of the hydraulic press, if the hydraulic pressure does not increase, the following is an analysis of common problems.
1. During operation, if it is found that the pressure cannot go up or down, it is likely that the reversing valve has failed, causing the system to continue to unload or maintain high pressure.
2. The damping hole of the relief valve is blocked, there are burrs on the main valve core, and there is dirt in the valve core, the valve hole and the gap, etc., which may cause the main valve core to become stuck and in the fully open position, the hydraulic pressure output by the hydraulic pump will The oil returns directly to the tank through the relief valve, that is, the pressure oil line and the return oil line are short-circuited, resulting in a pressure-free system.
3. In a system with a one-way valve, if the direction of the one-way valve is installed in the opposite direction, the pressure may not rise.
4. Leakage inside and outside the system, such as serious leakage between the valve core and the valve body hole, will also cause the system pressure to fail to increase.

Hydraulic Press Machine Speed Slow How To Solve

-

  If your  hydraulic press machine  speed gets slowly,following are methods to solve it. 1. Air in the hydraulic cylinder When the hydraulic press machine pressing speed gets slowly, we should first consider that air in the hydraulic cylinder, interrupt the corresponding exhaust operation through the exhaust equipment of the machine, and check whether there is air in the movement direction of the piston rod. If so, it may be If the sealing ring is defective, the sealing ring should be changed in time. 2.  Check whether the hydraulic pump is operating normally When the hydraulic press machine moves slowly and the hydraulic pump runs irregularly, and sometimes it may be blocked or slightly seized, it means that there is a problem with the hydraulic pump and the hydraulic pump should be repaired or changed in time. 3. Check the operation of the piston When the hydraulic cylinder of a hydraulic press machine with a buffer device is intermittently started in reverse, the piston will be temp

Hydraulic press offers several benefits when it comes to manufacturing components for AI servers forming: AI server forming ○ Precision and Consistency Hydraulic press allows for precise and consistent shaping of metal components used in AI servers. This is essential for ensuring that the parts fit together correctly and function optimally within the server system. ○ Complex Shapes Hydraulic press enables the creation of complex and intricate metal parts that may be required in the construction of AI servers. This is particularly important as servers often contain components with non-standard shapes to accommodate various functionalities and space constraints. ○ Material Strength The process of hydraulic press can enhance the strength and durability of metal components used in AI servers. This is crucial for ensuring the reliability and longevity of the server hardware, especially in high-demand computing environments.
