The article considers the reasons of hydraulic drives failure at industrial plants.<\/p>\n
A smooth operation of such equipment depends on the purity class of working fluid. In recent years there has been an increase in power of modern drives, which increases the requirements not only to a drive itself, but also to its hydraulic oil. \u00a0\u00a0GlobeCore<\/i><\/b> filtration plants, are designed to purify working fluids, reduces maintenance costs of hydraulic equipment, improves turnaround time and reduces downtime.<\/p>\n
In general, the working fluid is characterized by a number of parameters: viscosity, density, flash point, etc. \u00a0And the most important parameter, in terms of reliability and trouble-free operation – is a purity class. \u00a0With decreasing of purity class – \u00a0the following effects are observed:<\/p>\n
It has been estimated that \u00a070% of failures in \u00a0hydraulic equipment was caused \u00a0by solid contaminants in working fluid. \u00a0Therefore, purity class of working fluid directly affects the service life of hydraulic system components. \u00a0Fuel purity can be achieved only with competent filtration.<\/p>\n
British Hydromechanics Research Association (BHRA) conducted a research to determine a relation of hydraulic equipment and the class of working fluid. \u00a0The objects of research were metalworking, construction and transport machines, forging presses and marine hydraulics. \u00a0Obtained data showed that upgrading of working fluid can substantially reduce the turnaround time. \u00a0These results were also confirmed in the studies at Franklin Institute (USA). \u00a0They researched particles in oil effecting a piston pump with a working pressure of 200 bar. \u00a0The basic results are shown in Table 1.<\/p>\n
