Causes of Pressure Drop in a 315-Ton Single-Arm Hydraulic Press
Causes of Pressure Drop in a 315-Ton Single-Arm Hydraulic Press:
The pressure regulating valve spring of the 315-ton single-arm hydraulic press becomes loose. If there is no change after pressurization, it may be due to valve core wear and prolonged use, causing leaks and preventing pressure buildup.
The hydraulic pump of the single-arm hydraulic press wears out and leaks after prolonged use.
Wear or aging of the sealing ring on the piston head in the cylinder causes oil leakage and prevents pressure buildup.
The electromagnetic valve of the single-arm hydraulic press has been in use for too long, leading to valve core wear and significant leakage, resulting in inadequate pressure.
High temperatures cause the hydraulic oil to become too thin, making it difficult to build up high pressure.
Leakage in the pressure-holding one-way valve of the 315-ton single-arm hydraulic press.
Leakage in oil pressure pipelines, cylinder welds, piston rod seals, and other areas.
Insufficient oil level in the hydraulic press's oil tank, causing air suction at the filter element.
