Lishanski's vibratory cavitation pump

摘要

A vibratory cavitation pump is provided that includes a working cylinder having an fluid inlet and a fluid outlet, a rod extending into the cylinder, a piston fixed to the rod, a plate fixed to the rod and spaced from the piston, an activator slidably mounted to the rod between the piston and the plate and an oscillating pumping mechanism operably connected to the rod to move the rod with respect to the working cylinder. The sliding activator creates cavitation in the fluid being pumped to increase the ease of pumping the fluid, such as high viscosity fluids. The pump can also include an external cylinder disposed around the working cylinder to impart rotational motion to the incoming fluid, thereby enhancing the cavitation created in the fluid by the pump, rendering the fluid easy to displace.

主权项

1. A vibratory cavitation pump comprising:
a. a working cylinder having an fluid inlet and a fluid outlet; b. a rod extending into the cylinder; c. a piston fixed to the rod; d. a plate fixed to the rod and spaced from the piston and spaced inwardly along the rod from an outer end of the rod; e. an activator slidably mounted to the rod between the piston and the plate, the activator including a central passage through which the rod extends, the central passage defining a space between an exterior surface of the rod and the activator; and f. an oscillating pumping mechanism operably connected to the rod opposite the end of the rod to move the rod with respect to the working cylinder wherein the plate includes a number of apertures therein.
