Reasons and Solutions for Low Pressure in the 315 Ton Hydraulic Press System
Reasons and Solutions for Low Pressure in the 315 Ton Hydraulic Press System
Reasons for Low Pressure in the 315 Ton Hydraulic Press System:
The hydraulic cylinder, after prolonged use, may develop leaks or cavitation.
If the pressure relief valve, responsible for adjusting the pressure range of the hydraulic press, malfunctions, it can lead to pressure reduction.
A faulty pressure relief valve in the hydraulic press will inevitably result in decreased pressure.
Leakage in the inlet valve causes the hydraulic fluid in the upper chamber to flow back.
Wear and tear of the one-way valve in the 315-ton hydraulic press leads to reverse leakage and pressure drop.
Solutions for Low Pressure in the 315 Ton Hydraulic Press System:
Check Oil Level:
- Verify the oil level; if it's below the marked level, replenish the hydraulic fluid.
- If the oil level is normal, inspect the inlet and outlet pipes for any leaks and eliminate them if found.
Inspect Inlet and Outlet Seals:
- If the seals on the inlet and outlet pipes are excellent, check the operation of the inlet and outlet pressure valves.
- If the pressure valves cannot close properly, dismantle them to inspect for cracks, damage to components, clear oil routes and holes, and check if the stiffness of the tension spring has reduced. Resolve any issues promptly.
Examine Hydraulic Pipes and Filters:
- If the pressure valves are functioning normally, inspect hydraulic pipes or filters.
- If the pipes are clear, examine the hydraulic pump and replace it if necessary. If hydraulic oil foaming is detected, check the device at the return oil pipe. If the oil level in the return pipe is below the oil level in the tank, reinstall the return oil pipe.
Overview of the Hydraulic Press:
- The hydraulic press primarily consists of a bow-shaped frame, punching slide, operating platform, four guide columns, upper main cylinder, proportional hydraulic system, servo electrical system, pressure sensor, and pipelines.
In conclusion, when the 315-ton hydraulic press exhibits slow operation, it is crucial to systematically identify and eliminate the root causes. Careful attention to each potential issue is essential, ensuring that the equipment operates free from underlying problems.
