Thinking about the Service Life - Hydraulic Hoses

Hydraulic hoses form an integral part of the hydraulic systems but most commonly these are not paid much interest up until and unless a failure happens. Hoses have a limited life span which too goes undermined due to different factors. The additional costs incurred on its repair works renders a lot more expense than the whole hose replacement. Issues like damage due to ingression of pollutants, ancillary damage to surrounding parts, revival of hydraulic oil and so on adds on to the expenses.

The main factors of hydraulic hose failures are:

Focusing Physical damage

It's a tested fact that 80 % of the hose failures are the resultant of an external physical damage. Many of the times squashing, pulling, kinking, abrasion etc. causes hose failure. The brushing of hoses either against each other or versus the adjacent surfaces (abrasion) is usually the most conventional kind of damage. An easy solution to all these problems is attentiveness. A little attention and prompt check can assist avoid all these issues. Besides, polythene spiral wraps can also be applied to avoid abrasion. The security of clamps must be likewise focused.

Examining Several Airplane Bending

Generally, if a hose bends in more than one plane then it consequently twists its wire support. This twisting can be eventful for the hoses as 5 degrees of twist can deduct 70 % of service life while a 7 degree twist can wind up reducing the life span by 90 %. In effective hose-assembly option and routing cause several plane bending. In case the hose is subjected to the device or actuator motion, improper and inadequate clamping too can be a factor for numerous plane bending.

Maintaining Operating Conditions

The ultimate life span of hydraulic hose grossly depends on the operating conditions. Simply puts, the working conditions of hose really determines its service life. Every hose's rubber tube and cover are sensitive to the extremes of temperature, too high temperature level at day time or too cold temperature level during the night can effect the hose's age negatively. Severe pressure fluctuations too, can show harmful for the hose service life.
