What are the installation requirements for four-column hydraulic oil cylinders?

1. For the installation of the four-column hydraulic oil cylinder, it is necessary to make a special protective cover for the seal, and fill the inlet and outlet oil ports and air vents with special materials to ensure that the seal will not be cut when the piston is installed in the cylinder.

2. It is necessary to check whether the piston rod of the four-column hydraulic press is bent, especially the long-stroke cylinder. Bending piston rods can damage the cylinder head seals, causing leaks, creep and loss of motion and leading to cylinder failure.

3. The axis of the cylinder should be parallel to the guide rail. Pay special attention to the case where the piston cylinder is fully extended. If the two are not parallel, there will be a large tendency force and cause failures such as cylinder jamming, poor commutation, crawling and failure of the cylinder seal.

4. The parallelism error of the piston rod axis to the installation surface of the two ends shall not be less than 0.05MM.

5. For the hydraulic cylinder with a long stroke, the coupling between the piston rod and the table should be kept floating to compensate for the jamming and thermal expansion caused by the installation error.
