In the current context, in which the analysis of the failures by infrared thermography for the hydraulically operated machines is an increasingly widespread internationally method, starting from the year 2016, in Romania, at INOE 2000 - IHP Bucharest the first thermographic analyzes were laid made on hydraulic equipment. It is known that by maintaining normal limits of variation of the temperature and viscosity of the hydraulic oil in the actuation plants, are created the conditions of the productivity increase an...

The ?20-20-20? program provides a 20% reduction in greenhouse gas emissions (CO2 equivalent) compared to 1990, ie a 20% reduction of the final energy consumption compared to 2005, by increasing of the energy efficiency and increasing the share of renewable sources in the total energy mix to at least 20% until 2020. Starting from this European directive, the authors propose to develop a method of assessing the wear and operating status of hydraulic pumps, rotary hydraulic motors and hydraulic cylinders, without nec...

Hydrostatic transmissions create compliance between rigid functional parameters of a power-machine, e.g. an electric motor, and flexible functional parameters of the work machine, e.g. a crane hoist. Hydrostatic transmissions equip fixed or mobile machinery and guidance systems for: aviation, artillery, wind turbines, hydraulic turbine blades, etc. Any hydrostatic transmission includes at least two positive displacement machines: a pump, called transmission пїЅprimaryпїЅ and a motor, called transmission пїЅseconda...
