Abstract
The utility model disk manifold type magnetic drive pump comprises the pump housing (1), pump cover (2), pump shaft (3), impeller (4), interior magnet rotor (5), separation sleeve (6), outer magnet rotor (7), link press span (8), bearing housing (9), live axle (10), it is characterized in that interior magnet rotor (5) and outer magnet rotor (7) are disc, magnet rotor (5) magnet rotor (7) in the axial direction corresponding matching couple drive outer with disc in disc; In disc, between magnet rotor (5) and disc outer magnet rotor (7), disc separation sleeve (6) is set, outer portion and link press span (8) inner ring surface of disc separation sleeve (6) are sealedly and fixedly connected, and make pump shaft chamber seal isolation.It makes the axial dimension of magnetic drive pump greatly reduce, and the occasion that meeting spatial installation dimension is little uses, and processing, installation and maintenance are conveniently.
Description
Technical field
The utility model relates to the magnetic drive pump being, mainly for delivery of the magnetic drive pump of inflammable, explosive, poisonous, harmful or somewhat expensive dense media, technological points is the improvement to inside and outside magnet rotor.
Technical background
Magnetic drive pump comprises the pump housing 1, pump cover 2, main shaft 3, impeller 4, interior magnet rotor 5, separation sleeve 6, outer magnet rotor 7, link press span 8, bearing housing 9, live axle 10, separation sleeve 6 and pump cover 2 are sealedly and fixedly connected and make shaft seal, are arranged on interior magnet rotor 5 on main shaft 3 in separation sleeve 6 to rotate with the outer magnet rotor 7 mating band main shaft 3 of separation sleeve 6 outside.
In prior art, magnet rotor 5 and outer magnet rotor 7 are cylindrical shape, it is inside and outside ring fit system, although relatively good on magnetic coupling drive performance, but columnar interior magnet rotor 5 is longer at axial fit dimension with outer magnet rotor 7, make the axial dimension of pump larger, this is less demanding for driving force, the occasion that space mounting size is little, is often not easy to install and use and maybe can not installs and uses.Not, its telescopic separation sleeve is comparatively strong because medium to produce eddy current in bottom, and the acrobatics in medium easily produces wearing and tearing to separation sleeve, reduces working life.
Model utility content
The purpose of this utility model improves for the shortcoming deficiency of above-mentioned prior art, provides a kind of disk manifold type magnetic drive pump, to reduce the axial dimension of pump, adapts to the little occasion of installing space and use, and improve sealability and the reliability of separation sleeve.
The utility model magnetic drive pump comprises the pump housing 1, pump cover 2, pump shaft 3, impeller 4, interior magnet rotor 5, separation sleeve 6, outer magnet rotor 7, link press span 8, bearing housing 9, live axle 10, be arranged on and be arranged on the outer magnet rotor 7 mating band pump shaft 3 driven on axle 10 axle head outside interior magnet rotor on pump shaft 3 axle head 5 and separation sleeve 6 and rotate, it is characterized in that, the interior magnet rotor 5 be arranged on pump shaft 3 axle head is disc, being arranged on the outer magnet rotor 7 driven on axle 10 axle head is disc, magnet rotor 5 magnet rotor 7 in the axial direction corresponding matching couple drive outer with disc in disc; In disc, arrange disc separation sleeve 6 between magnet rotor 5 and the outer magnet rotor 7 of disc, outer portion and link press span 8 inner ring surface of disc separation sleeve 6 are sealedly and fixedly connected, and make pump shaft chamber seal isolation.
The utility model due to interior magnet rotor 5 and outer magnet rotor 7 are two disc types corresponding matching couple drive in the axial direction, interior magnet rotor 5 reduces greatly with the axial dimension of outer magnet rotor 7, the axial dimension of magnetic drive pump is reduced greatly, and the occasion that meeting spatial installation dimension is little uses.
Meanwhile, in disc, magnet rotor 5, outer magnet rotor 7 and disc separation sleeve 6 are processed more simple, and installation and maintenance are also convenient.Due to the disc that disc separation sleeve 6 is planes, separation sleeve does not have recess, medium can not produce obvious eddy current on separation sleeve, and medium is little to separation sleeve wearing and tearing, can improve the working life of separation sleeve 6 and pump, reduces amount of maintenance.
