What should be paid attention to when selecting the hydraulic cylinder? In consideration of the weight of the object, the hydraulic cylinder with appropriate pressure is selected, which is quite beneficial to the system maintenance and safe operation in the future. When working in the continuous rolling seamless pipe plant, the system pressure is 14 MPa and 31 MPa, which is relatively high.

When there is pressure, you can calculate the cylinder diameter and rod diameter of the hydraulic cylinder according to f = n (p * s). Here, I default that your hydraulic cylinder has no rod cavity filled with oil and the object is lifted, so you can choose. Moreover, the cylinder rod thread of the hydraulic cylinder is the design standard. As for other standards, you can rely on the corresponding common standards, or let the cylinder manufacturer do it according to your requirements.

In addition, the synchronization of each hydraulic cylinder during synchronous action shall also be considered. The synchronous motor can be considered, and the synchronization rate is 4% ~ 7%. Since it is up and down movement, it is very important to install a balance valve on the circuit!

After the hydraulic cylinder is assembled, it shall be responsible for the search to determine which complete machines may be used continuously, which complete machines can be reused after general repair, and which complete machines must be changed. The above is the introduction in this respect. I hope it can be helpful to your work.
