As a product group, hydraulic cylinders are nearly as common as motors and pumps combined. So if you operate plenty of hydraulic equipment, it is very likely that cylinder repair cost is a significant part of your overall operating expenses. In this article you can get the best details about hydraulic repair service in Derby and hydraulic hose repair service.

According to some studies, up to 25 percent of mechanical equipment failures are failures of design. If we apply this to hydraulic cylinders, then as many as one in four hydraulic cylinders aren't adequately designed for the program they are operating in.
#1. Bent Rods
Bending of cylinder rods may be brought on by insufficient pole diameter or material power, improper cylinder mounting arrangement or a combination of all three. When the pole bends, the deforming load is put on the rod-seal.
#2. Rod Finish
The surface finish of the cylinder rod has a substantial effect on the life span of the rod seal. If the surface roughness is too low, seal life can be decreased because of inadequate lubrication. If the surface roughness is too high, contaminant ingression is raised and an unacceptable amount of leakage past the rod seal may result.
#3. Ballooned Tubes
Ballooning of the cylinder tube is usually brought on by insufficient wall thickness and/or material strength for the cylinder's operating pressure. When the tube balloons, the right tolerance between the piston seal and tube wall is dropped, allowing high-pressure fluid to bypass the seal.
#4. Insufficient Bearing Area
If the surface area of the bearing bands in the gland and on the piston are insufficient to adequately support the side thrust transferred into the cylinder, excessive load is put on the rod and piston seals.
