TROCHOID PUMP FOR TRANSFERRING HIGH-VISCOSITY LIQUID UNDER HIGH PRESSURE

摘要

Disclosed is a trochoid pump for transferring high-viscosity liquids under high pressure. The trochoid pump includes an idler coupled to an inner through-hole inside a housing to be rotated, a rotor inserted into an inside of the idler, and a shaft configured to rotate the rotor, wherein the idler is provided with an inner toothed groove, into which the rotor is inserted and which has a plurality of projecting teeth, and recessed grooves, which are recessed with a predetermined depth along an outer circumferential surface thereof in a circumferential direction. Unlike an existing gear pump or trochoid pump, the trochoid pump for transferring high-viscosity liquids can reduce a viscous friction force, and can reduce the driving power.

主权项

1. A trochoid pump comprising:
an idler rotatably coupled to an inner through-hole on an inside of a housing, a rotor inserted into an inside of the idler, and a shaft rotating the rotor, wherein the rotor is inserted into the idler and the idler has an inner toothed groove having a plurality of projecting gear teeth formed thereon, and a recessed groove formed on an outer circumference with a predetermined depth in a circumferential direction.
