The present invention relates to a diagnosis unit of oil pressure equipment for construction machinery, wherein the diagnosis unit coupled to an oil pressure line supplies oil pressure to the oil pressure equipment when a failure is generated in the oil pressure equipment, thereby diagnosing the position and the degree of the failure in the oil pressure equipment. According to the present invention, a diagnosis unit of oil pressure equipment for construction machinery comprises a first connecting part detachably mounted on an oil tank; a second connecting part detachably mounted on the oil pressure equipment; an oil pressure pump sucking working oil from the oil tank through the first connecting part, and supplying the working oil to the oil pressure equipment through the second connecting part; an electric motor actuating the oil pressure pump; a coupling connecting and disconnecting the oil pressure pump and the electric motor; multiple valves formed on an oil pressure line connected between the first connecting part and the second connecting part, and controlling the flow of the working oil supplied to the oil pressure equipment by the oil pressure pump; a detecting sensor detecting working oil information on at least one of the flow rate, the pressure, the flow, or the temperature of the working oil flowing in the oil pressure line; and a control part controlling the actuation of the electric motor, the coupling, and the oil pressure pump, and diagnosing the cause and the position of a failure in the oil pressure equipment using the working oil information detected by the detecting sensor. |
