What are the precautions for the four-column hydraulic oil cylinder device

Four-column hydraulic press (also known as four-column hydraulic press) when installing and using the cylinder device, special attention must be paid to the following matters to ensure stable operation, long life and less failure of the equipment:

1. Preparation before installation

Check whether the seal is complete: whether the seal ring and O-ring etc. are intact when the cylinder is delivered to avoid oil leakage after installation.

Check the cleanliness of the cylinder inside and outside: ensure that no impurities, iron filings, or contaminants enter the cylinder block or rod area.

Positioning accuracy: the four-column guide rail and the cylinder mounting seat must be vertical and coaxial, otherwise the operation will cause cylinder pulling or oil leakage.

Second, the installation process precautions

Correctly connect the oil pipe: confirm that the high-pressure oil pipe is correctly connected to avoid damage caused by misconnection of high-pressure oil return.

The fixing method should be reasonable: when using flange or thread connection, it should be tightened according to the manufacturer's standard to avoid eccentricity.

Avoid partial load or lateral force: the force of the cylinder piston rod should be aligned with the center line of the guide sleeve to avoid uneven force.

Exhaust treatment for initial operation: exhaust the cylinder after installation to prevent hydraulic shock or jitter.

3. Maintenance during use

Check the piston rod surface regularly: whether there are scratches, rust or oil stains, clean and oil protection in time.

Observe the seal status: Replace the seal immediately if there are signs of oil leakage.

Control the working pressure: avoid long-term overpressure operation, affecting the life of the cylinder.

Replace the hydraulic oil regularly: keep the oil clean to prevent internal wear of the cylinder.

Safety tips

Do not disassemble the cylinder with pressure

Cannot force return with load

If the piston rod shakes abnormally, stop the machine immediately for inspection
