Abstract

The invention discloses a novel transmission screw pump. The novel transmission screw pump comprises a pump body and a feeding box. The feeding box is provided with a feeding port, a discharging port and a power input port. The feeding box is fixed to the feeding end of a stator of the pump body, and the discharging port of the feeding box is communicated with a feeding port of the stator. A cylindrical bearing block is fixed to the power input port of the feeding box in a sealing manner. According to the novel transmission screw pump, the bearing block and the feeding box are combined, and an original bearing installing structure which is complex, large in size, high in cost and prone to leakage is eliminated. The integral length is greatly reduced. Bearings can be assembled in the bearing block. The overall novel transmission screw pump is small and simple, a leakage structure is eliminated, and a large number of materials are saved. The size and cost are reduced. The appearance is beautified, assembling and maintaining are facilitated, and maintaining and using are convenient.

Description

technical field [0001] The invention relates to a novel transmission screw pump. Background technique [0002] The screw pump is widely used as a feeding device. The pump body is a positive displacement rotor pump. It relies on the volume change of the sealed cavity formed by the rotor and the stator to suck and discharge the material. It has stable flow, small pressure pulsation, and self-priming ability. It has the advantages of low noise, high efficiency, long life, reliable operation, etc., and does not form eddy current when conveying the medium, is not sensitive to the viscosity of the medium, and can transport high-viscosity medium. It has been used in the transportation of emulsion explosives and other substances. [0003] At present, the overall structure of the screw pump is complex, with many parts, easy to leak, difficult to assemble, maintain and manufacture, large in size, high in cost, and the transmission device connected between the pump body and the driving...
