The present invention relates to a device for economically and conveniently measuring the amount of leakage from a hydraulic component, which has a small size by performing measurement using a capillary phenomenon without a cylinder for collecting a leaking liquid. The hydraulic leakage measuring device with a metal capillary tube structure using a capacitor comprises: a capillary tube where a packing is combined with the bottom thereof in order to be directly in contact with an object to be measured for leakage, and is composed of an air inlet and a liquid inlet; a capacitor which is inserted into the capillary tube; an air pump which supplies air to the air inlet; a liquid pump which supplies a liquid to the liquid inlet; and a recovery line which recovers the liquid supplied from the liquid pump upon completion of measurement. Therefore, the hydraulic leakage measuring device can significantly increase the accuracy in measuring the amount of leakage higher than the accuracy of a measuring device using a general scale or a length measuring instrument, can be advantageous in the durability and measurement repeatability of an object to be measured for leakage, and can measure the changing amount of leakage over time. |
