Problems solved by technology

However, in the current single screw pump, the suction chamber, the rotor chamber and the shaft chamber are all set separately, and are generally connected by flanges, and then sealed with a sealing ring. The sealing ring has aging problems, which leads to liquid leakage. Not only wastes energy, but also causes environmental pollution, and most of the common single screw pumps have poor suction, and the effect is not good when transporting high-viscosity fluids

Abstract

The invention discloses a single-screw pump which comprises a driving motor, a rotating shaft chamber, a suction chamber, a rotor chamber and a delivery chamber, wherein the driving motor, the rotating shaft chamber, the suction chamber, the rotor chamber and the delivery chamber are connected in sequence. A rotating shaft is arranged in the rotating shaft chamber and driven by the driving motor, the suction chamber is provided with a material suction inlet and a winding shaft, a rotor and a stator are arranged inside the rotor chamber and meshed with each other, the delivery chamber is provided with a material delivery outlet, the rotating shaft is connected with the rotor through the winding shaft, the shell of the suction chamber, the shell of the rotating shaft chamber and the shell of the rotor chamber are integrally formed, and the rotating shaft and the winding shaft are respectively of a helix structure. The single-screw pump does not deform or move in the operating process, is good in sealing performance, high in suction and capable of delivering fluid with different viscosities, and has popularization and application value.

Description

technical field [0001] The invention relates to the technical field of pumps, in particular to a single-screw pump. Background technique [0002] The screw pump is a new type of machine for conveying liquids. It has the advantages of simple structure, safe and reliable operation, convenient use and maintenance, continuous and uniform liquid output, and stable pressure. The screw pump can transport lubricating oil, fuel oil, various oils and polymers. Polymers, viscous liquids, etc. However, in the current single screw pump, the suction chamber, the rotor chamber and the rotating shaft chamber are all set separately, and are generally connected by flanges, and then sealed with a sealing ring. The sealing ring has aging problems, which leads to liquid leakage. It not only wastes energy, but also causes environmental pollution, and most of the current common single screw pumps have poor suction, and the effect is not good when transporting high-viscosity fluids.
