FIELD: machine engineering.
SUBSTANCE: device to lubricate the support bearing of the turbomachine rotor comprises a suction pump, a suction pipe which is connected to the oil return line of the cavity. Outside oil chamber the compensation tank is set, the upper chamber which is communicated with the drain line, the latter is made of two independent pipelines connected in parallel to the oil chamber so that intake oil of a pipeline placed in the bottom of the cavity, and an oil intake other - higher than the first. Lower cavity of the compensation tank is communicated with the suction line suction pump.
EFFECT: implementation of the invention will increase the efficiency of the turbomachine by reducing the hydraulic losses in the flow part of the body and increase the reliability of the oil system when stopping the turbomachine.
