a paint pump

Abstract

The invention discloses a coating pump, and belongs to the technical field of fluid pumps. The coating pump comprises a pump body, a feeding port is formed in one end of the pump body, and a vortex-shaped vortex channel is formed in the other end of the pump body. A partition wall is arranged at the position, close to the feeding port, inside the pump body, and an installing tube is arranged at the position, between the partition wall and a plunger piston, inside the pump body. A transmission shaft is installed on the installing tube in a rotating mode and penetrates through an installing cavity, and a rotating disc is fixedly installed at the position, inside the installing cavity, of the transmission shaft. A floating disc is arranged inside the installing cavity, a first impeller is fixedly installed on the transmission shaft, a circulation gap is formed between the floating disc and the rotating disc, and multiple through holes corresponding to the circulation gap are formed in the installing tube. The area of the section of the vortex channel is gradually increased outwards from the center of a vortex, a second impeller is fixedly installed on the transmission shaft and used for guiding fluid into the vortex channel, and a discharging port is formed in the tail end of the vortex channel. The technical problems that an existing coating pump is insufficient in suction volume and low in output efficiency are solved, and the coating pump is widely applied to continuously conveying the fluid.

Description

technical field [0001] The invention relates to a pump, more particularly to a paint pump, and belongs to the technical field of fluid pumps. Background technique [0002] The paint pump is a fluid material conveying device, especially suitable for conveying materials that cannot be damaged, such as oranges, cosmetics containing active agents, blood preparations, biopharmaceuticals, preparations, sucrose containing additives, maltose, etc. [0003] In terms of types, paint pumps are mainly divided into plunger pumps and rotor pumps. Among them, rotor pumps are widely used because they are not easy to clog during delivery. [0004] However, in the field of painting and spraying, there are strict requirements on the particle size of the output fluid materials, and the output of excessively large particle materials is not allowed to affect the spraying effect. In order to solve this problem, the existing treatment measures are to add filter equipment to the pipeline for convey...
