FIELD: oil and gas industry.SUBSTANCE: device comprises a hollow body in the form of a cylindrical chamber with a bottom and an outlet for pumping a working fluid through a separation filter; the body integrates a working fluid rotation actuator, a ring reducing piece, a ring vortex chamber and a ring diffusor placed on an external surface of the body, as well as a multichannel jet device in the form of two coaxial ring elements rigidly connected to the body with arched discharge channels circumferentially arranged between their contact critical surfaces with a critical section of the outlets for facilitation the connection of the ring vortex channel with the ring diffusor. According to the invention, the multichannel jet device is mounted between flanges which have at least three through holes connected with lodgements. The above implementation provides a possibility to remove ring elements when exhausted. The fluid rotation actuator is equipped with screw blades having a winding pitch decreasing to the bottom.EFFECT: more reliable operation of the device.4 cl, 4 dwg |
