Abstract (en)

[origin: WO2020214056A1] Electric vibration pump has an electromagnet (1), consisting of a core (15) and a winding (16), a vibrator with an armature (2) and a rod (3), and a pump with a housing (11) and a piston (8), while the armature (2) of the vibrator is connected with the core (15) of the electromagnet (1) on one side and with the rod (3) on the other side, on which a shock absorber (4) is fixed, a diaphragm (6) is mounted and a pump piston (8) is set, located in the operating chamber (33) of the pump housing (11). The pump housing (11) is made with channels (30, 31) for connecting the operating chamber (33) to the discharge cavity (32) of the pump, equipped with a built-in check valve (9) and with arc-shaped filtering meshes (12) covering the pump housing (11) along the perimeter of the fluid being pumped from the well, installed to form a flowing volume (18) of purified liquid connected through the check valve (9) with the operating chamber (33) for alternating connection or disconnection.
