Способ относится к оценке технического состояния гидроцилиндров. Для обеспечения достоверности диагноза путем повышения точности оценки утечки создается перепад давления контролируемой среды, в качестве которой используется воздух. Для определения утечек через уплотнители перепад давления через уплотнители создается в результате перемещения штока, при этом измеряют давление контролируемой среды в полости низкого давления, объем контролируемой среды, вытесненной из полости высокого давления, и объем контролируемой среды, поступившей в полость низкого давления при неподвижном штоке, после чего расчет утечки контролируемой среды производят по формулам.The method relates to the assessment of the technical condition of hydraulic cylinders. To ensure the accuracy of the diagnosis by improving the accuracy of leak assessment, a pressure drop of the controlled medium is created, which uses air as its quality. To determine the leakage through the seals, pressure drop through the seals is created as a result of moving the stem, while measuring the pressure of the controlled medium in the low-pressure cavity, the volume of the controlled medium displaced from the high-pressure cavity, and the volume of the controlled medium entering the low-pressure cavity with a fixed stem, after which the calculation of the leakage of the controlled medium is made according to the formulas.
