    • A device for measuring an oil leak in a hydraulic cylinder comprises: a hydraulic cylinder; a suction part which sucks oil leaking from the hydraulic cylinder using a pressure difference; a temperature measuring part which measures the temperature of the sucked oil; a filling container which is filled with fluids having the same constitution as the leaking oil in a certain amount and is filled with the leaking oil transferred from the suction part; and a leaking oil amount measuring part which measures the amount of the oil leaking from the hydraulic cylinder by compensating the water level change of the filling container with a flow coefficient measured according to the viscosity of the leaking oil changed depending on the temperature of the leaking oil measured in the temperature measuring part.
    • 一种用于测量液压缸中的漏油的装置,包括:液压缸; 吸入部,其利用压差吸入从液压缸泄漏的油; 测量吸油温度的温度测量部件; 填充容器,其填充有与泄漏油相同构造的流体,并且填充有从吸入部分传送的泄漏油; 以及泄漏油量测量部件,其通过以根据泄漏的温度而变化的泄漏油的粘度测量的流量系数补偿填充容器的水位变化来测量从液压缸泄漏的油的量 在温度测量部分测量的油。
