BOREHOLE VIBRATION PUMP Russian patent published in 2010 - IPC F04F7/00 

FIELD: engines and pumps.

SUBSTANCE: device is intended for being used in everyday life and in factories for pumping liquids from deep boreholes, wells and other sources. Vibration borehole pump includes electromagnets, the forces of anchors of which are directed to different sides, working chamber 7 and valves. Pump is equipped with rubber and metal shock absorbers 5 and made in the form of two steps, working chamber 7 of the first pump step is formed with two resin and metal shock absorbers 5, which are rigidly connected to anchors of electromagnets 4, and to shell 6 installed between them and in which there arranged is suction 11 and pressure 12 valves. The second pump step has similar construction, but the force created with stiffness of resin and metal shock absorbers 5 exceeds the force of the same shock absorbers 5 in the first step by the value of the force created with liquid pressure obtained in the first step. Delivery cavity of the first step is connected to suction cavity of the second step. Electric power supply of the pump is performed from half-wave AC rectifier, where electromagnets of the first step are powered from one half-wave, and electromagnets of the second step are powered from the other half-wave.

EFFECT: increasing pump capacity and head at minimum power costs.
