FIELD: engineering industry.
SUBSTANCE: method is intended for diagnosing hydraulic units and hydraulic systems of positive displacement type, including mobile machine control and deceleration systems. Diagnostics method of hydraulic units and hydraulic systems of positive displacement type consists in the fact that hydraulic unit is loaded with hydraulic resistance installed in delivery main line, liquid temperature is determined in drain and discharge main lines and as per temperature change there assessed is technical state. As diagnosed parametre, there also used is electrostatic potential in triboelectrising device installed at hydraulic resistance inlet.
EFFECT: improving measurement accuracy.
