Abstract
The centripetal spiral fluid pump consists of a motor, centripetal spiral blades, a circular sealing ring and a bidirectional flange, wherein the rotating shaft of the motor is a hollow rotating shaft, and the centripetal spiral blades are arranged on the inner wall of the hollow rotating shaft. The centripetal helical blade rotates at a high speed along with the hollow rotating shaft of the motor, a very low negative pressure is formed at the inlet of the hollow rotating shaft, so that sucking and huge centripetal force are generated, fluid rotates along with the helical blade while obtaining mechanical energy, and the fluid gushes towards the center of the rotating shaft from the periphery, so that the fluid is pumped from one end of the hollow rotating shaft to the other end of the hollow rotating shaft, and the mission of the fluid pump is completed. The new fluid pump is called a radial inflow screw fluid pump.

The invention content is as follows:
the utility model aims to overcome the defects of the existing centrifugal pump, and particularly provides a novel centripetal spiral fluid pump, which is assembled with a fluid pump and a power source motorAre integrated together. The technical scheme of the utility model be realized like this, centripetal spiral fluid pump comprises motor, centripetal helical blade, circular seal ring, two-way flange, and the pivot of motor is a hollow rotating shaft, and centripetal helical blade is installed to hollow rotating shaft's inner wall. As shown in fig. 1. The motor is composed of a hollow rotating shaft, a stator coil, a rotor coil, a thrust bearing, a motor shell and end covers at two ends of the motor, as shown in fig. 2, fig. 2 is a schematic diagram of the principle of a centripetal spiral fluid pump, wherein centripetal spiral blades of the fluid pump are shown in a three-dimensional view, and because a plan view is not intuitive, a motor part is shown in a sectional view. The thrust bearings are arranged on two end covers of the motor and play a role in supporting the motor rotor, and because the radial component force is zero and only the axial component force exists when the centripetal spiral fluid pump runs, the design does not adopt the conventional radial bearing but adopts the thrust bearing for bearing the axial component force. The outside of the thrust bearing is provided with a circular sealing ring which plays a role in sealing between the hollow rotating shaft and the two-way flange, and the outermost surface of the thrust bearing is connected with the external two-way flange, so that the thrust bearing is convenient to be connected with the inlet end and the outlet end of the fluid pump. The double-headed arrows in fig. 2 represent the directions of fluid flow in and out. The centripetal spiral fluid pump is a bidirectional fluid pump, and the fluid pump changes the rotating direction of a motor under the premise that the centripetal spiral direction is fixed, so that the inlet and outlet directions of fluid can be changed. The spiral of this design all adopts right spiral. A complete centripetal helical blade is composed of a helical leading-in blade, a helical main blade and a helical leading-out blade. Firstly, the part of the spiral blade with the thread height from low to high is called a spiral leading-in blade; secondly, the part of the spiral blade with consistent thread height is called a spiral main blade; third, the height of the screw thread of the screw blade is changed from high to low, and the screw blade is called a screw leading-out blade. As shown in fig. 3, in the figure
Is the length of the cut along the spiral line,
is the height of the thread. Such asThe design of the helical blades allows the input fluid to maximize axial power through the rotating helical blades while minimizing the rotational inertia of the output fluid. The radial inflow type spiral vane has two combination forms in the fluid pump, one is a one-dimensional spiral type, and the other is a multi-dimensional spiral type, as shown in fig. 4. The principle of the radial inflow spiral fluid pump is as follows: the rotating shaft of the motor is a hollow rotating shaft, the inner wall of the hollow rotating shaft is provided with a centripetal helical blade, the centripetal helical blade rotates at a high speed along with the hollow rotating shaft of the motor, the centripetal helical blade forms a low negative pressure at the inlet of the hollow rotating shaft, so that sucking is generated, a huge centripetal force is generated, fluid rotates along with the helical blade while obtaining mechanical energy, and the fluid surges to the center of the rotating shaft from the periphery, so that the fluid is pumped from one end of the hollow rotating shaft to the other end of the hollow rotating shaft, and the service of the fluid pump is finished. The new fluid pump is called a radial inflow screw fluid pump.
