Abstract
A symmetrical radial split-type magnetic drive pump comprises a magnetic drive portion (2), impellers (4) and a pump shaft (10), and is characterized in that a pump body is formed by two water inlet sections (3), a plurality of middle sections (6) and a water outlet section (7). A guide vane (5) and the pump shaft (10) are arranged in the pump body. The pump shaft (10) is provided with a coupling (1), the magnetic drive portion (2) and a plurality of impellers (4). A throttle shaft sleeve (9) is arranged on the water outlet section corresponding to the pump shaft. The throttle shaft sleeve (9) is provided with a throttle sleeve (8). The symmetrical radial split-type magnetic drive pump is simple and reasonable in structure and convenient to assemble and overhaul.
Description
Technical field:
the utility model relates to pump, particularly relates to a kind of symmetrical radially split type magnetic drive pump.
Background technique:
magnetic drive pump adaptable across fields such as chemical industry, oil, refinery, pharmacy poisonous, contain solid particle medium, contain the toxic gas medium, near the conveying of boiling point medium.Because the magnetic driving equipment that adopts extraordinary intensity, magneticfocusing, push-and-pull magnetic circuit to be coupled, has compact structure, volume is little, torque is big, eddy current is little, magnetic transmission efficiency advantages of higher.But the assembling of present magnetic drive pump pump section, maintenance inconvenience are brought certain trouble to production.
Summary of the invention:
The purpose of
the utility model provides a kind of simple and reasonable, assembling, the symmetrical easily radially split type magnetic drive pump of maintenance.
the utility model is achieved in that a kind of symmetrical radially split type magnetic drive pump; Comprise that magnetic drives part, impeller, pump shaft; It is characterized in that: the pump housing is made up of two inlet segments, several stage casings, a water exit end, is provided with stator and pump shaft in the pump housing, and pump shaft is provided with coupling, magnetic drives part, plurality of impeller; The corresponding pump shaft of water exit end is provided with restrictor sleeve, and restrictor sleeve is provided with orifice sleeve.
the utility model is simple and reasonable, and assembling, maintenance are conveniently.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Among
figure 1, coupling, 2, magnetic drive part, 3, inlet segment, 4, impeller, 5, stator, 6, stage casing, 7, water exit end, 8, orifice sleeve, 9, restrictor sleeve, 10, pump shaft.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
are with reference to accompanying drawing; A kind of symmetrical radially split type magnetic drive pump comprises that magnetic drives part 2, impeller 4, pump shaft 10, is characterized in that: the pump housing is made up of two inlet segments 3, several stage casings 6, a water exit end 7; Be provided with stator 5 and pump shaft 10 in the pump housing; Pump shaft 10 is provided with coupling 1, magnetic drives part 2, plurality of impeller 4, and the corresponding pump shaft of water exit end is provided with restrictor sleeve 9, and restrictor sleeve 9 is provided with orifice sleeve 8.During practical implementation, motor drives the outer magnet rotor rotation that magnetic drives part through coupling, magnet rotor rotation in outer magnet rotor drives through magnetic force, and interior magnet rotor is through the rotation of pump shaft impeller, and the medium that sucks from two water intakes like this transfers out from water outlet.Because pump partly adopts symmetric arrangement, water outlet in the middle of the water inlet of two ends, the two ends water inlet structure is symmetry fully, and axial force automatic balancing does not receive rate of discharge and variation in pressure.
