Abstract
The invention relates to a series connection combined labyrinth screw pump, and belongs to the technical field of general engineering equipment. At present, a general labyrinth screw pump is composed of one labyrinth screw body. A pump rotor of the series connection combined labyrinth screw pump is formed by two or more rotor rings in a series connection combining mode, and a pump stator is formed by two or more stator rings in a series connection combining mode. The rotors and the stators of different lengths and in different tooth shapes can be combined to adjust flow pressure, the demands under different working conditions can be met, and the defect of performance limits of one single labyrinth screw body is overcome.
Description
Technical field
The present invention relates to a kind of being combined through series connection formula labyrinth screw pump, belong to general engineering equipment technical field.
Background technique
At present, horizontal general use type Mazy spiral pump structure as shown in Figure 1, under the rotation of motor, in the working cavity that institute's fed sheet of a media is made up of pump inlet flange inflow pump rotor and stator, is discharged by pump discharge flange.
The Mazy spiral body that the main working parts of this pump is made up of a pair of rotor and stator, has at the outer surface of rotor and the internal surface car of stator the multiple thread that rotation direction is contrary.According to different designing requirements, this pump profile of tooth can be designed as triangle, trapezoidal, rectangle etc.Studies have shown that, the pressure of labyrinth screw pump is directly proportional to the length of Mazy spiral body within the specific limits.
At present, the Mazy spiral body of this pump is whole segmentation, and operating range is little, and heliconid is the comparatively difficulty of internal thread machining of stator especially.
Summary of the invention
For making up the deficiency of existing labyrinth screw pump, the present invention proposes a kind of being combined through series connection formula labyrinth screw pump.This pump can regulate flow pressure by the stator combination that turns of different length and different tooth forms, meets the requirement under different operating modes, and has overcome the problem of stator internal thread machining difficulty.
The being combined through series connection formula labyrinth screw pump that the present invention proposes, by existing labyrinth screw pump, being designed to pump rotor is composed in series by two or more rotor rings, pump stator is composed in series by two or more track rings, and on axial cross section, Normal section or the end face of each Mazy spiral body ring, profile of tooth can be designed to triangle, rectangle, trapezoidal, circular arc etc.
