FIELD: machine building.
SUBSTANCE: procedure for diagnosis of hydraulic drive with tank, hydro-accumulator and pressure gauge consists in recording changes of pressure in hydraulic drive and in comparing obtained characteristics with reference ones. The procedure is equipped with an additional sensor for control of level of liquid in the tank. There are also registered losses of working liquid in the hydraulic drive. The pressure gauge is installed in a gas cavity of the hydraulic accumulator. There are controlled both pressure of gas cavity charging, and working pressure of liquid.
EFFECT: raised reliability and efficiency of procedure operation due to control of losses of working liquid and control of pressure in gas cavity of hydraulic accumulator.
