Abstract

The invention relates to a hollow spiral shaft eccentric cavity pump without a vane wheel. A front spiral diversion body and a rear spiral diversion body are arranged in a conical hollow shaft provided with a water inlet and a water outlet and are respectively fixedly connected with the inner wall of the conical hollow shaft; the front end of the rear spiral diversion body is provided with a cavity conical body, and the front end of the cavity conical body is fixedly connected with the inner wall of the conical hollow shaft; and the wall of the cavity conical body is provided with a plurality of apopores. A rotor sleeve is arranged outside the conical hollow shaft, a rotor is arranged in the housing sheathed on the conical hollow shaft, and both ends of the conical hollow shaft are supported by bearings. The pump of the invention has the advantages of scientific and reasonable integral design, simple structure, convenient production, low material consumption, high material quality, low cost, easy assembly and disassembly, low daily maintenance, stable and reliable performance, energy saving and high efficiency and practicability. The pump of the invention is applicable to families, factories and mines, enterprises and institutions, agricultural irrigation, running water and other relative work units.

Description

technical field [0001] The invention relates to a centrifugal pump, in particular to a conical hollow screw shaft centrifugal cavity pump without an impeller. Background technique [0002] With the continuous development of science and technology, the application of liquid transmission technology is becoming more and more extensive. As the core liquid pump of the liquid transmission mechanism, it is extremely important and has reached the point where it cannot be abandoned. At present, there are many kinds and forms of liquid pumps, which can be used in different environments and show their different advantages and performances. However, in summary, the commonly used liquid pumps generally have the following common problems: [0003] 1. Large energy consumption: Commonly used liquid pumps are driven by a motor to rotate the pump shaft and impeller. Undoubtedly, the rotational torque is large. The impeller rotates in water with high resistance and large negative angle compone...
