Problems solved by technology
[0002] At present, conveying devices for high-viscosity materials such as adhesives, polyurethane, butyl rubber, and hot-melt adhesives at home and abroad generally use gear pumps, plunger pumps, screw pumps or diaphragm pumps to transport them. When the viscosity of the above materials is very high, gears are used alone. Pumps, plunger pumps, screw pumps or diaphragm pumps are not easy to convey, or are not easy to meter and convey, and the metering is inaccurate

Abstract
The invention discloses a high-efficiency three-screw pump, which includes a pump body, a bushing, a driving screw, a first driven screw, a second driven screw, an upper cover, a safety valve and a thrust coupling. At the front end of the pump body, the driving screw is arranged laterally in the middle of the pump body and protrudes from the front end of the upper cover, and the first driven screw and the second driven screw are respectively arranged inside the pump body and Cooperately arranged at the upper and lower ends of the driving screw, the bush is arranged in the pump body and is in contact with the first driven screw and the second driven screw, the safety valve is arranged at the upper end of the pump body, and the The thrust coupling is arranged on the upper cover and is respectively connected with the driving screw and the safety valve. Through the above method, the present invention utilizes the rotation of the screw to suck and discharge the liquid, which can be applied to the transportation of high-viscosity liquid, and the thrust coupling is added to improve the work efficiency, the operation is stable, the structure is solid, safe and reliable, and the service life is long .
Description
technical field [0001] The invention relates to the technical field of mechanical parts, in particular to a high-efficiency three-screw pump. Background technique [0002] At present, conveying devices for high-viscosity materials such as adhesives, polyurethane, butyl rubber, and hot-melt adhesives at home and abroad generally use gear pumps, plunger pumps, screw pumps or diaphragm pumps to transport them. When the viscosity of the above materials is very high, gears are used alone. Pumps, plunger pumps, screw pumps or diaphragm pumps are not easy to deliver, or are not easy to meter and deliver, and the metering is inaccurate. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a high-efficiency three-screw pump, which uses the rotation of the screw to suck and discharge the liquid, and can be used for the transportation of high-viscosity liquid. The thrust coupling is added to improve the working efficiency and t...
