Existing Under Water Pumps has centrifugal Under Water Pumps, its structure forms as shown in Figure 1, include the pump housing, impeller, pump cover, pump shaft, pedestal cylinder, pedestal cylinder can be connected to form by more piece docking, and be provided with bearing attic base and bearing on two pedestal cylinder butt ends, pump shaft can be to be constituted by the docking of two sections or multistage, bearing adopts ceramic slide bearing, corresponding each sliding bearing offers lubrication inlet opening, cooling inlet opening communicates with delivery side of pump pipeline by pipeline, high pressure in pump discharge pipeline is minded to introducing is lubricated sliding bearing cooling, in pump shaft upper end portion, be provided with mechanical seal device and prevent from minding leakage.
Above-mentioned prior art Under Water Pumps, structure is more complicated, and cost is high, assembling maintenance difficult.Medium easily leaks, and medium not only can produce certain leakage in mechanism's sealing place, and can produce a large amount of dielectric leakages when mechanism's seal arrangement is damaged, and has a large amount of danger of leaking of medium.When the medium that will carry is poisonous, inflammable, explosive medium, if a large amount of leakages occur medium in service, can cause security incident.
Model utility content
The utility model is to improve for above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, manufactures simple and conveniently, and cost is low, convenience easy to maintenance, and safety in utilization is good
magneto drive Under Water Pumps.
The utility model magneto drive Under Water Pumps, is characterized in that by the pump housing 11, pump cover 12, pump shaft 13, impeller 14, pedestal cylinder 2, be arranged on the bearing means 31 between pedestal cylinder 2 and pump shaft 13, 32, mechanical seal device 5, interior magnet rotor 15, separation sleeve 16, outer magnet rotor 17, link press span 18 and bearing housing form, and pedestal cylinder 2 is by two sections of socket 2a, 2b or the docking of multistage socket form, at two ends socket 2a, between 2b, be fixedly connected with bearing attic base 3 and sealing gland 4, between bearing attic base 3 and pump shaft 13, be provided with sealed type grease lubrication rolling bearing 31, between bearing attic base 3 and sealing gland 4, on pump shaft, be provided with mechanical seal device 5, between the upper end plate 20 of pedestal cylinder 2a and pump shaft 13, be provided with sealed type grease lubrication rolling bearing 32, on the axle head of the pump shaft 13 on pedestal cylinder 2a outside end plate 20, be fixedly connected with magnet rotor 15 in installation, separation sleeve 16 is sealedly and fixedly connected with the upper end plate 20 of pedestal cylinder 2, link press span 18 is fixedly connected with the upper end plate 20 of pedestal cylinder 2, on motor shaft or on live axle, outside fixed installation, magnet rotor 17 coordinates with interior magnet rotor 15, drive pump shaft 13 to rotate, separation sleeve 16 adopts glass steel material.
The utility model structure is simpler, and cost is low, assembles convenience easy to maintenance, and good airproof performance is used safety.
The utility model is fixedly connected with bearing attic base 3 and sealed type grease lubrication rolling bearing 31 between two ends socket 2a, 2b, and its cost is low, and installation and maintenance are convenient.Between two ends socket 2a, 2b, be fixedly connected with sealing gland 4 and be provided with mechanical seal device 5 simultaneously, to medium, can fully effectively seal, prevent that medium from entering in the pedestal cylinder 2a of top, pump shaft 13a and upper junction member in pedestal cylinder 2a are not immersed in medium, relatively can reduce the material requirement of the inner pump shaft 13a of pedestal cylinder 2a, reduce costs.Bearing means 31,32 adopts airtight grease lubrication rolling bearing, and relative usage sliding bearing, without being equipped with special lubrication mechanism, simplifies the structure and manufacture cost.In adopting, the magnetic force of magnet rotor 15, separation sleeve 16, outer magnet rotor 17 drives, further improve the reliability of sealing, separation sleeve 16 adopts glass steel material simultaneously, can realize the dry running continuously of pump and find time, and without separation sleeve 16 inner chamber cooling mechanisies are set, not needing medium to be incorporated in separation sleeve 16 inner chambers, be that medium is not introduced in pump shaft upper end portion, can not produce dielectric leakage, further improve and only used Security, fully meet poisonous, inflammable, explosive medium and use.
