INERTIAL SEPARATOR PUMP Russian patent published in 2022 - IPC B01D17/38 

FIELD: fuel industry.

SUBSTANCE: invention relates to liquid separation devices and can be used to purify oil, petroleum and heavy fuel of internal combustion vehicle engines and to separate petroleum products or petroleum from water. The inertial separator pump contains a housing with an electric motor with a disk rotor placed in it. The pump impeller is fixed to the end of the rotor. The spacer covers the rotation area of the rotor with the impeller and has an axial hole located at the inlet of the impeller. There are holes in the groove connecting it to the opposite end of the spacer, on which the separator is fixed. The separator contains a spiral-shaped first channel ending with the first outlet pipe, along the outer generatrix of which a slit is made connecting it with a spiral-shaped second channel ending with the second outlet pipe. The inlet of the first spiral-shaped channel is located at the end of the separator and is combined with one of the holes of the spacer channel-collector. On the axis, the separator is provided with a hole, combined on one side with the axial hole of the spacer, and on the other side with an inlet pipe.

EFFECT: ensuring a compact combination of a liquid separator with spiral channels with a pump of a mixture of these liquids, as well as explosion safety.
