Hydraulic cylinder is essential equipment that you are present of your industry has hydraulic equipment present. Just as any other hydraulic component like Hydraulic Hose With Fittings the cylinder does cost a considerable amount. You sure want to save it from failure or repairs. Yes, you can do it. You need to take care of a variety of aspects to ensure that it does not impact the cylinder in a negative way.
Though the best way to extend the longevity is Hydraulic Cylinder Repair but it would be best if you can eliminate the possibility of failure altogether.
Cylinder barrel distension is usually caused by insufficient wall thickness and/or material strength for the working pressure of the cylinder. When the hose expands, the correct tolerance between the piston seal and the hose wall is lost, allowing high-pressure fluid to bypass the seal. This fast fluid can erode the seal, and the local heating caused by the pressure drop across the piston shortens the life of the seal, ultimately leading to premature failure of the piston seal.
If the surface area of the stuffing box and piston bearing band (wear band) is insufficient to adequately support the lateral pressure transmitted to the cylinder, the rod and piston seals will be exposed to excessive stress. This deforms the seal and ultimately leads to premature failure.
In order for a hydraulic cylinder to function properly, it is essential to supply a constant pressure fluid into the hydraulic cylinder. Special seals help create a tight connection between the cylinder and the movable rod. Damaged hydraulic cylinder seals can leak liquid from the cylinder and reduce performance. With proper care of the hydraulic seal, you can easily prevent the seal from leaking. Schedule regular visual inspections of all seals in the Hydraulic Power Packs system. Check for signs of hardening, cracking, or general wear. When storing the hydraulic seal, be careful not to damage it before installing it.
Another significant reason for cylinder failure is the surface finish of the cylinder rod. The surface finish can have a significant impact on the life of the rod seal. If the surface is smooth, poor lubrication will shorten the seal life. On the other hand, if the surface roughness is too high, the ingress of contaminants will increase, resulting in unacceptable levels of leakage through the rod seal.
In a conventional double-acting cylinder, the effective area, and therefore the force generated by the piston and rod sides of the cylinder, is not equal. Therefore, if the rod side of the cylinder has half the effective area of the piston side, the same pressure will generate half the force of the piston side.
If for some reason the piston side of the double-acting cylinder is pressurized to prevent the fluid from escaping from the rod side, the pressure on the rod side of the cylinder will increase until the forces are balanced or the cylinder is catastrophically damaged. So better ensure to get the Hydraulic Cylinder Repair on time.
