The single-machine double-stage compressor of the low-temperature freezing equipment comprises a compressor shell, bearing grooves, a liquid storage cavity, outer rings and inner rings, the bearing grooves are symmetrically formed in one side of the compressor shell in an embedded mode, the outer rings are arranged in the bearing grooves, the inner rings are arranged in the outer rings, and the liquid storage cavity is arranged in the compressor shell. And screw rods are installed in the inner walls of the inner rings in a clamped mode, and limiting grooves are formed in the middle positions of the outer surfaces of the inner rings and the middle positions of the inner walls of the outer rings in an embedded mode. The single-machine two-stage compressor of the low-temperature refrigeration equipment is provided with steel balls and a liquid guide cavity, in the using process, the steel balls abut against through rotation of the balls, the steel balls abut against the liquid guide cavity to ascend, so that lub
