Abstract
The utility model discloses a main shaft for a highly corrosive magnetic drive pump. The main shaft comprises a shaft body, the cross section of one end of the shaft body is circular, step-shaped protrusions are arranged at the other end of the shaft body, the middle section of the shaft body is a rotor cooperation position, and three semi-circular reflux tanks are evenly distributed in the radial direction of the side wall of the middle section of the shaft body. The main shaft for the highly corrosive magnetic drive pump is stable in working state, and the reflux tanks are arranged on the side wall of the main shaft.
Description
Technical field
The utility model relates to a kind of pump housing equipment, specifically a kind of deep-etching magnetic drive pump main shaft.
Background technique
In prior art, main shaft simple in structure, friction is large, intensity can not meet usage requirement, main shaft coordinates unstable with rotor.
The model utility content
The utility model purpose is to provide on a kind of stable working state, main shaft sidewall the deep-etching magnetic drive pump main shaft with back flash.
The utility model technical solution problem provides following scheme:
A kind of deep-etching magnetic drive pump main shaft, comprise axis body, it is characterized in that: an end section of described axis body is for being circle, and the other end is provided with step-like projection, the intermediate section of described axis body is the rotor cooperation position, three semicircle back flashes of radial equipartition on the sidewall of the intermediate section of described axis body.
It is conical that one end of described axis body is.
The utility model main shaft one end is circular, with the pump case choma, coordinate, the other end is step-like projection, with the spacer combination, coordinate, during pump work, main shaft does not rotate, stable working state, three semicircle back flashes of the position radial equipartition that main shaft coordinates with rotor, make the friction of main shaft reduce, round-corner transition, circle centre position is without through hole.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, a kind of deep-etching magnetic drive pump main shaft, comprise axis body 1, one end section of described axis body 1 is for being circle, the other end is provided with step-like projection 2, the intermediate section of described axis body 1 is rotor cooperation position 3, three semicircle back flashes 4 of radial equipartition on the sidewall of the intermediate section of described axis body 1, and an end of described axis body 1 is conical 5.
Claims (2)
1. a deep-etching magnetic drive pump main shaft, comprise axis body, it is characterized in that: an end section of described axis body is for being circle, and the other end is provided with step-like projection, the intermediate section of described axis body is the rotor cooperation position, three semicircle back flashes of radial equipartition on the sidewall of the intermediate section of described axis body.
2. deep-etching magnetic drive pump main shaft according to claim 1, it is characterized in that: an end of described axis body is conical.
