Fluid feeding mechanism and double-cylinder plunger pump thereof

Abstract

The utility model belongs to the technical field of plunger pumps, and particularly relates to a fluid feeding mechanism and a double-cylinder plunger pump thereof. Comprising a bottom plate and further comprises a cylinder body, two material pushing channels are arranged on one side of the cylinder body, and a first feeding hole and two first discharging holes are further formed in the cylinder body; the two rotary shunting discs are respectively propped against the cylinder body; the two push rods are mounted on the bottom plate; the cylinder body is further provided with two flow dividing hole sets, each flow dividing hole set comprises a first flow dividing hole, a second flow dividing hole and a third flow dividing hole, a flow dividing groove is formed in the side, close to the cylinder body, of the rotary flow dividing disc, and the flow dividing grooves enable the first flow dividing holes and the second flow dividing holes to be communicated or enable the second flow dividing holes and the third flow dividing holes to be communicated. Through reciprocating motion of the two push rods, materials are sucked into the material pushing channel, and through reciprocating rotation and diversion of the rotary diversion disc, the discharging frequency of the materials is improved, and the working efficiency is improved.
