Lubricating oil control system of steam compressor

The invention relates to the technical field of compressors, in particular to a lubricating oil control system of a steam compressor, which comprises a main motor, a gearbox, a compressor and an oil supply assembly, the oil supply assembly comprises a main oil tank, a first one-way valve, a main oil pump, a second one-way valve, an electric auxiliary oil pump, a first pipe, a water-cooled oil cooler, a fine filter, a second pipe, a high-level oil tank, a third pipe, a third one-way valve, an electromagnetic valve and a fourth pipe. After the oil supply assembly is normally powered off, the electromagnetic valve is opened immediately, before the main motor is started, oil is supplied through the electric auxiliary oil pump, the high-position oil tank is filled with lubricating oil through the third one-way valve, after the oil supply assembly is abnormally powered off, the electromagnetic valve is opened, and the lubricating oil in the high-position oil tank can return oil immediately through gravity to supply
