Technical Field

Background

The single screw pump is a rotor type volumetric pump which relies on the intermeshing of the screw and the liner to produce a change in volume in the suction and discharge chambers to deliver the fluid. The main working parts consist of a bushing of a spiral cavity, i.e. a stator, and a single-head screw, i.e. a rotor, engaged with it in the stator cavity. The single-screw pump proposed by the prior art publication No. CN115929620B comprises a mounting seat, a feeding chamber, a rotating assembly, a pump body and a first driving assembly; a feeding inlet is formed in one side of the feeding chamber away from the mounting seat; a spiral feeding shaft is arranged in the feeding chamber and provided with a first end and a second end; a discharge hole is formed in one side, close to the first end, of the feeding chamber; the rotating assembly is arranged in the feeding chamber and comprises two rotating rings sleeved at the first end and the second end respectively; a first annular channel communicated with the discharge hole is formed between one of the rotating rings and the first end, and the first annular channel is used for allowing materials to pass through; a second annular channel is formed between the other rotating ring and the second end; the rotor of the pump body passes through the discharge hole and is connected with the first end; the output end of the first driving component penetrates into the feeding chamber and is connected with the second end. However, when large discharge capacity is needed, two modes are not needed, one is to further increase design parameters on the basis of a single-line single-screw pump, and the discharge capacity is improved by increasing structural parameters of the pump; the other method adopts a multi-line single-screw pump design method, meets the displacement requirement by increasing the line number of the pump, and causes each structural parameter of the screw pump to be unreasonable regardless of the line number, especially the increase of the eccentricity, and has great negative influence on the hydraulic characteristic and the service life of the screw pump.
